What, if anything, will get you to go to the basement when severe storms threaten? A text? A call from someone you trust? An official warning or maybe visual confirmation of a tornado on the ground? This gets into behavioral science & how we make smart decisions, but seeing the KARE-11 helicopter footage from the 1986 Brooklyn Park twister got me thinking. I know, it happens rarely, as my wife of 29 years likes to point out.
I really wrestle with this: by showing amazing tornado video are we PROVING the threat is real, prompting people to get off the sofa & do the right thing -OR- are we encouraging more people to whip out their iPhones & remake a scene from the movie Twister, placing themselves in danger? Research suggests most of us need multiple sources of confirmation (siren, text, e-mail, TV warning, NOAA Weather Radio, app alert, etc) before we do the right thing - and head for the basement.
Today I'm grateful for a Canadian breeze: 70s with a dew point in the 50s. A shower may sneak in this evening - a better chance of showers & T-storms on Sunday, especially south of St. Cloud & the Twin Cities. Next week? 70s and low 80s, cooler than average; a few stormy episodes.
When it comes to heat & humidity Minnesota will be a whine-free zone.

Savor The Sun. Clouds will increase as the day goes on, a series of weak stormy ripples tracking along a persistent frontal boundary. Friday's welcome cool front does a U-Turn and returns north Sunday, sparking more numerous showers and T-storms, but a shower or T-shower could sneak into the MSP metro by late afternoon or evening. The earlier in the day you head outside, the better.
A Very Wet First Half of 2013. Dr. Mark Seeley has more information on a very soggy start to the year over the Upper Midwest; here's an excerpt from his latest edition of WeatherTalk: "...Further, the Midwest Climate Center informs us that the first six months of 2013 (January-June) has been the wettest in history for Michigan (20.80" statewide average), Iowa (24.93" statewide average), Wisconsin (21.85" statewide average), and Illinois (29.11" statewide average). In Minnesota it has been the 3rd wettest first six months of the year averaging 16.93 inches statewide (this trails only 17.31 inches in 1908 and 17.83 inches in 1896). Harmony, MN (Fillmore County) has reported nearly 35 inches of precipitation so far this year and their annual normal is 34.63 inches!" (photo credit: Paul Brooks).
Year To Date Rainfall. Portions of southeastern Minnesota have already seen a year's worth of rain, 30-35", as of July 19, based on NOAA rainfall guidance.
A More Seasonable Week. Temperatures will trend cooler average (highs near 83-84, which is average for this time of year). Showers and T-storms are most likely Sunday into Monday, another round Friday. We get a welcome break from the heat and humidity, with one possible exception.
Trending Cooler. The 00z NAM is hinting at a hot, humidified Monday with highs near 90F. Otherwise expect highs in the upper 70s to near 80 into much of next week, a little free A/C.
Welcome Canadian Air. The same cool front dropping temperatures and humidity levels over the Upper Midwest will spread strong to severe T-storms across the Great Lakes and Ohio Valley into parts of New England Saturday; by Sunday much of the Northeast will experience a dip in temperature and dew point. Enjoy the break, because more heat and moisture will build into next week. The far west remains dry and ripe for more wildfires. 84 hour NAM loop: NOAA.
5-Day Rainfall. A stalling cool front will ignite the heaviest showers and T-storms from Kansas City eastward to Louisville and Nashville, more heavy rain for the Florida Panhandle and a monsoon soaking for Arizona.
Saturday Flash Flood Potential. Data from HRRR and other weather models suggest the greatest potential for T-storm flooding today from Cleveland to Erie to Elmira, New York, with more flooding possible over the Florida Panhandle. The Sioux Falls area may pick up as much as 1-2" of rain. Map: Alerts Broadcaster.
Hot And Bothered. Much of America experienced highs well up into the 90s yesterday. Factoring dew points above 70 heat indices poked into the hundreds from coast to coast. Only the Upper Midwest and portions of northern New England saw any relief. A weakening cool front of Canadian origin will provide slight relief for the Northeast by tomorrow. Map: Ham Weather.
Anniversary Of 1986 Televised (KARE-11) Tornado - What Prompts You To Go To The Basement? We've never had more effective ways of getting severe storm warnings: media, sirens, NOAA Weather radio, e-mails, texts, apps. We're all multitasking with various devices, one eye on the television, the other on a laptop or smart phone/tablet. When you see video of a tornado on the ground does it increase the odds of you heading for the basement, or does it tempt you to go outside to see if you can tape the tornado on your phone or camera, or maybe drive somewhere safer? Bad idea. I really wrestle with this, with showing video of tornadoes. On the one hand it provides unmistakable verification that rotation is, in fact, producing an actual tornado. People usually need multiple sources of confirmation from different sources before they do the right thing and head for safety. Another part of me thinks we're distracting the audience, tempting them to go outside and see the tornado for themselves. Here is today's installment of Climate Matters, remember the Twin Cities tornado of 1986, covered from beginning to end during a newscast, and tracked in real-time by KARE-11's helicopter. There has never been a tornado quite like this one. "WeatherNation Chief Meteorologist was on set at KARE 11 when the 1986 Tornado tore through the Twin Cities. Seeing the compelling footage again made him ask, what prompts YOU to take cover? Is it seeing a tornado in your area on TV? Is it hearing your local meteorologist talk about radar? Maybe a text message to your phone? We want to hear from you. Tell us below what gets you to the basement or sheltered space."
Tornado "LIve On KARE-11" 27 Years Ago. Video from the nearly stationary, white, F-2 tornado has been studied by tornado researchers - it's almost as if the tornado wanted to be photographed. Luckily it hit a park (Springbrook Nature Center) in Brooklyn Park, and not a heavily populated subdivision or shopping mall, although I was pretty shaken on the air, thinking that any moment this thing would veer into a nearby neighborhood and we would be witnessing carnage, live, on the air. That didn't happen, thank God. Here's an excerpt of an interview I gave KARE-11 on Thursday: ""People are understandably skeptical because 70% of tornado warnings are false alarms and that breeds this sense of apathy and complacency," Douglas explained. As we all know, the other 30% of tornado warnings can lead to events with devastating, and sometimes, deadly results. Douglas says here in the metro area, we've had a relatively smooth summer weather-wise so far. But, he says, don't become complacent. "Usually the tornado season peaks in May and June in Minnesota but everything has been delayed by at least one or two months. We're kind of limping into summer and so I have a hunch that we are going to be tracking severe storms much of the summer," he concluded."
When Tornadoes Strike, Which Way Do They Travel? This is pretty cool, one of the best visualizations and explanations of tornado tracks. Of course there are exceptions to every rule, as the deadly EF-5 El Reno tornado proved, when it suddenly veered 45 degrees to the northeast, claiming the lives of 3 accomplished tornado researchers. Details from io9.com: "These gorgeous maps have the answer. Created by datavisualization expert John Nelson, these "Tornado Travel Maps" depict the relative proportion of more than 60 years of U.S. tornadoes by their direction of travel. Notice a pattern? The maps are the latest in Nelson's growing ouvre of gorgeous, natural-disaster-themed cartography. To date, he's produced maps depicting more than a century's worth of global earthquakes, over 150 years of tropical storms and hurricanes, and a slew of major U.S. wildfires. Each map is created from data made publicly available by organizations like NASA, NOAA and the USGS. Every one of them is stunning, combining troves of data with arresting visualizations to great (and incredibly informational) effect. Nelson's latest creation is no exception. What's more, it might one day be used to improve emergency response protocols for some of America's most devastating tornados..."
Watch: Surreal Photos Of Nature's Wrath. This is part of a TED Talk, one I encourage you to watch. Here's an excerpt from Camille Seaman's story at Huffington Post: "...For several thousand years we have allowed a story that gives man dominion over all the Earth's creatures to lead us to this place in which we as humans are destroying not only our own habitat, water supplies, air quality etc., but are taking out millions of our brother and sister species in the process. The underlying goal of my work is to help trigger an emotional connection, one that I hope will spark a relationship between the viewer and this planet. It is so easy to do harm to something or someone when you make it separate from yourself, when you can place it below you or see yourself as somehow more important than the "other." If you came to know that you cannot do harm to any other being or thing without doing harm to yourself, you might make different choices. Our planet is an awesome, wonderful and giving verdant place that we so easily take for granted..."

California Wildfire Now Tops 22,000 Acres. Mark my words: this will be one of California's worst fire seasons on record. The state picked up only 31% of their normal rain and snow since January 1, setting the stage for a growing drought, and a potentially historic run of fires, which usually don't peak until October. Here's a clip from U.S. News and World Report: "A massive wildfire that has been burning out of control in Southern California forced the evacuation of about 6,000 people on Wednesday, as firefighters are struggling to contain the 22,800-acre blaze. The Mountain Wildfire, as it is called, started in the San Jacinto Mountains on Monday, just west of Palm Springs. Since it started, the fire has more than tripled in size. On Tuesday, the wildfire had destroyed several buildings and burned through more than 14,000 acres of "steep and rugged terrain." The blaze claimed 22,800 acres by Thursday morning, and was 15 percent contained..."

NASA Talks Global Warming, "Second Warmest June On Record". Here's the intro to a story at Design & Trend: "NASA reported that the only warmer June in the global temperature record was 1998, a year "juiced by global warming and El Nino." June of 2013 teeters between a weak La Nina season and ENSO-neutral conditions, meaning that climate experts projected normally below-average global average temperature. According to Think Progress, the accumulation of heat-trapping greenhouse gases were responsible for contributing to the second hottest June on record. NASA's Goddard Institute for Space Studies reports that the June 2013 surface temperature anomalies, which can be viewed here..."

June 2013 Global Climate Update. Here's a clip from NOAA's climate.gov: "In June 2013, many areas of the world experienced higher-than-average monthly temperatures. According to the latest statistics from NOAA’s National Climatic Data Center, the globally averaged temperature for the month tied with 2006 as the fifth warmest June since record keeping began in 1880. It also marked the 37th consecutive June and 340th consecutive month—that’s a total of more than 28 years—with a global temperature above the 20th-century average. The last below-average June temperature was June 1976 and the last below-average temperature for any month was February 1985..."
The map above shows temperatures relative to average across the globe for June 2013. Shades of red indicate temperatures up to 11° Fahrenheit warmer than the 1981–2010 average and shades of blue indicate temperatures up to 11° Fahrenheit cooler than the average.
Record Heat In June Extends Globe's Streak To 340 Months. Meteorologist Andrew Freedman from Climate Central has more details on the findings for June; here's a clip: "Global average surface temperatures during June were either the second or the fifth-warmest on record for the month, based on analyses by NASA and NOAA, respectively. The two agencies keep tabs on global temperature trends using large networks of surface monitoring stations and statistical approaches to fill in gaps where stations are sparse, but they use slightly different methods to analyze the data, which can result in slight differences in their rankings. June continued the long-term warming trend tied to manmade greenhouse gas pollution as well as natural climate variability. The planet has not recorded a single month with temperatures below the 20th century average since February 1985, when the cult classic film “The Breakfast Club” was released, and the last year with a cooler-than-average June was in 1976. This year so far is tied with 2003 as the seventh-warmest year on record, NOAA said..." (Image above: NASA).

Bill To Shift NOAA Resources To Weather Marches On. I'm all for having more powerful and accurate weather models, but coming at the expense of climate modeling? Not sure that's an inspired idea. Here's a clip from Andrew Freedman at Climate Central: "A House bill that would mandate the nation’s top weather and climate agency shift its priorities more toward short-term weather forecasting has sped its way through the legislative process. The House Science Committee is expected to consider it in the next few weeks. The bill is aimed at changing how the National Oceanic and Atmospheric Administration (NOAA) prioritizes its missions of weather, climate and ocean science. Critics of the bill say that prioritization will shortchange long-term climate research in favor of improving forecasts of extreme weather..."

9 Most Common Regrets Of The Living And Dying - And What To Do About Them. My goal (like so many others) is to live a life of no regrets, to not look back and say "could-have, should-have, would-have". That's why I found this story from Next Avenue so interesting; here's a clip: "In spending time with patients during the last three to 12 weeks of their lives, Ware gleaned vital insight into the concerns and regrets of those faced with imminent death. Here are the core regrets as she describes them in her Inspiration and Chai blog.
1. I wish I'd had the courage to live a life true to myself, not the life others expected of me.
This was the most common regret of all. When people realize that their life is almost over and look back clearly on it, it is easy to see how many dreams have gone unfulfilled. Most people had not honored even a half of their dreams and had to die knowing that it was due to choices they had made, or not made.
It is very important to try and honor at least some of your dreams along the way. From the moment that you lose your health, it is too late. Health brings a freedom very few realize, until they no longer have it..."
Extreme Mowing. 0 to 60 in 4 seconds. On a lawn mower? Why not. Gizmag.com has the details; here's a clip: "Billed as world’s fastest lawn mower, the Mean Mower is a (heavily) modified version of on Honda’s HF260 Lawn Tractor that can make 0-60 mph (96 km/h) in 4.0 seconds – fast enough to put most exotic full-sized autos to shame. This racy take on the riding mower develops 96 Nm (70 lb.ft) of torque, 109 hp (which gives it roughly 100 more ponies than most of its lawn tractor brethren) and has a power-to-weight ratio of 532 bhp/tonne thanks to a weight of only 140 kg (308 lb). To keep the whole thing legit, grass cutting remains very much a part of the equation. Yes it still cuts grass, but only at speeds up to 15 mph (24 km/h). But once the lawn has been carefully manicured then feel free to take it out on the local autobahn and run it out to an (estimated) 130 mph (209 km/h). Helmet recommended..."

Nonsense And Sensitivity: Top Climatologist Slams The Economist For Yet Another "Flawed And Misleading" Piece. Here's a clip from Think Progress: "Here’s The Economist’s idea of responsible journalism. Begin by quoting UN chief climate negotiator Yvo de Boer on the forthcoming fifth assessment by the Intergovernmental Panel on Climate Change (IPCC):
THAT report is going to scare the wits out of everyone.
Then dig up some unpublished, unsubstantiated chart to make the case “it might be less terrifying than it could have been.” No, seriously, the Economist devoted an entire article to argue that a draft climate change report “might be less terrifying than it could have been.” I guess if The Economist had been leaked the draft medical report from a decade ago that Steve Jobs had a neuroendocrine tumor of the pancreas (rather than a carcinoma), they would have written an entire piece explaining his condition “might be less terrifying than it could have been...”

The CIA Wants To Know How To Control The Climate. Geo-engineering climate may be a technological savior, or a dangerous pipe-dream, right? The Verge and Mother Jones have a fascinating story on how the CIA and how they are taking a morphing climate very seriously; here's the intro: "The US Central Intelligence Agency isn't just interested in gathering intelligence on foreign powers and enemies. As it turns out, Langley is also investigating the feasibility of altering the environment to fight the effects of climate change. The CIA is currently funding, in part, a $630,000 study on geoengineering, the science of using experimental techniques to modify Earth's climate, as Mother Jones reports. The 21-month-long study was commissioned by the National Academy of Sciences, a nonprofit group of scientific advisors to the government, and a final report on its findings is due to be published in the fall of 2014..."
Reid Blames Climate Change: "West Is Burning". Here's a clip from The Las Vegas Review-Journal: "As firefighters head home from Southern Nevada, U.S. Sen. Harry Reid on Wednesday blamed “climate change” for the intense blaze that consumed nearly 28,000 acres and drove hundreds of residents from their homes around Mount Charleston this month. Reid said the government should be spending “a lot more” on fire prevention, echoing elected officials who say the Forest Service should move more aggressively to remove brush and undergrowth that turn small fires into huge ones. “The West is burning,” the Nevada Democrat told reporters in a meeting. “I could be wrong, but I don’t think we’ve ever had a fire in the Spring Mountains, Charleston range like we just had. “Why are we having them? Because we have climate change. Things are different. The forests are drier, the winters are shorter, and we have these terrible fires all over the West....”

Saudi Arabia Aims To Become The World's Largest Renewable Energy Market. I had a vaguely out of body experience when I came across this headline. Saudi Arabia? World's biggest renewable energy market? It probably makes sense. All that sunshine, and a gradually depleting natural resource of oil under their feet - The Kingdom probably has the right idea here, as explained at arabnews.com: "Saudi Arabia aims to become the world’s foremost market for renewable energy with an aggressive investment budget of $109 billion. By 2032, the country strives to generate as much as a third of the Kingdom’s energy demands using renewable energy (54 GW). Following the publicity surrounding the country’s major investment drive, King Abdullah City for Atomic and Renewable Energy (KACARE) released a series of documents detailing the revised National Energy Plan. In addition to the 41 GW of solar power, 25 GW of CSP and 16 GW of PV, the Kingdom is aiming to generate 18 GW of nuclear energy, 3 GW of waste to energy, 1 GW of geothermal and an additional 9 GW of wind power, specifically for water desalination plants..."

A Mixed Blessing
Meteorologists often come off as Spock-like, Doppler-loving automatons; finger-pointing nerds who relish a good storm. Truth? We do.
But when weather is persistently foul (Exhibit A: this spring) it's no fun predicting the future.
Every day brings a chorus of new complaints. "Can't you DO something about this lousy weather, Paul?" When's the last time a sportscaster got BLAMED for the Twins losing? Totally irrational - but I guess it comes with the turf.
Sure, we've had 3 plowable snowfalls in April, nearly 18" snow - the snowiest month of the season; almost 4 times more snow than fell in January!
But a fire-hose of Gulf moisture has returned, fueling a parade of very wet storms. The drought is fading fast and the metro area should avoid the most serious river flooding in the weeks ahead. So it's not all bad news, right?
Wait, I think I hear crickets.
Expect lukewarm sun today & Tuesday, followed by 1-2" rains and greening lawns later this week, as a huge storm stalls over the Plains. Wednesday's soggy cold front does a U-turn; more rain pinwheeling in from the east by late week. Wet snow could mix in by Friday.
Excuse me while go I yell at the weatherman.
"Ice Breakers" Hasten Winter's Retreat On Lake Minnetonka. This is new one - using boats and waverunners to accelerate ice-out? Can you tell locals are getting frustrated with our extra-late spring? Here's an excerpt from Lake Minnetonka Patch: "Boats—and even jet skis—were out on Lake Minnetonka yesterday trying to break up ice and hasten the arrival of open water season."
Photo credit: "The photo received more than 40 "like" on Lake Minnetonka's Facebook page in less than 24 hours.
Promising Fishing Opener Outlook? It's still pretty far out, but the cold, rainy (possibly snowy at times) atmospheric holding pattern that will torment us from Wednesday into Sunday should be gone by May 9. Highs on Fishing Opener Weekend may reach the 60s and 70s for metro lakes; 10 degrees cooler up north, but all things considered - not bad.
Big Changes. Mother Nature remains mellow today and much of Tuesday, but a cold slap across the face is shaping up by midweek, highs near 40F by Wednesday with a cold rain, possibly mixing with a little wet snow. There's another surge of moisture shaping up for late week, probably rain, but a little snow can't be ruled out Friday night. Showers spill over into Sunday; 60s returning next week.
Unusual For May. These cut-off lows are more typical in March or October, rare (but not unprecedented) for early May. The same pattern that's pumping a steady stream of drought-busting moisture northward is also pulling unusually chilly air south out of Canada. It's hard to have one without the other. A storm aloft is forecast to stall over Missouri, counterclockwise winds pumping more rain (and a little wet snow?) back into Minnesota by late Thursday into Saturday. GFS model: NOAA.
Nuisance Snow? Plowable? Probably not, but the fact that we're even having this conversation heading into early May. GFS model runs are hinting at minor amounts of slush the latter half of the week. If anything does stick it won't be in your yard for long. Good grief.
PG Rated Weather Map. PG for pretty grim. But right now the latest NAM model keeps accumulating snow over southeastern Minnesota, western Wisconsin and parts of Iowa, maybe 4-6" or more from near Rochester to Eau Claire? The axis of slush may wave back and forth from east to west in the coming days - too early to know who may wake up to a (very rare) May snowfall later this week.

Midwest States Continue To Fight Record Flooding. Here's an excerpt of a story at The Los Angeles Times: "After months of drought, many areas of the Midwest on Saturday continued to fight off flooding from rising rivers that are not expected to crest for several more days. National Weather Service forecasters expect flooding to continue throughout the week along the Des Plaines, Fox, Illinois and other rivers and their tributaries in Illinois. U.S. Geological Survey monitors in the area have recorded record floods. Illinois Gov. Pat Quinn has declared 48 counties in his state disaster areas. In making the announcement, he noted that water is receding in some areas but rising in others. “We are continuing to do everything we can to provide the personnel and resources needed to fight the flooding,” Quinn said..."

Some Good News For Fargo. Flood Warnings are posted for the Red River now, a Flood Watch for northwestern Minnesota and northeastern North Dakota for rapidly melting snow and ice dams causing sudden rises in streams and rivers. The latest NOAA forecast for Fargo shows a crest near 37 feet between Tuesday night and Wednesday night, a foot lower than predicted Saturday, and 3-4 feet below the high water mark set in 2009.
Effects Of Midwest Flooding Will Be Felt For Months. NBC News has a good overview of the problems, including a wild swing from not enough water in the Mississippi River a couple months ago to severe flooding in recent days; here's an excerpt: "...To the north, a damaged lock may keep a stretch of the Illinois River closed to commercial shipping traffic for weeks, the U.S. Army Corps of Engineers said. Flooding has halted the transport of corn and soybean barges at certain terminals on the river, Reuters reports. The disruptions could cause significant disruptions in the flow of grain and corn in the second-highest soybean producing state. Reuters reports almost 60 percent of U.S. grain exports are transported on the Mississippi River and its tributaries. Grain prices at export terminals at the Gulf of Mexico climbed this week to the highest level in at least a month due to the disruptions..."

Up To 375 Flood Gauges To Turn Off Because Of Fund Cuts. Doyle Rice from USA Today has a head-shaking story, another victim of "The Sequester". Coming at a good time huh? Here's an excerpt: "Just in time for the spring flood season, the federal sequester is threatening to shut off funding for hundreds of stream gauges used by the U.S. Geological Survey to predict and monitor flood levels across the country. "The USGS will discontinue operation of up to 375 stream gauges nationwide due to budget cuts as a result of sequestration," the USGS notes on its website. Additional stream gauges may be affected if USGS partners at state and local agencies reduce their funding support..."
NOAA's National Weather Service Completes Doppler Radar Upgrades. New "dual-pol" Doppler upgrades do a better job calculating precipitation types and rainfall and snowfall amounts - so sensitive they can even detect the debris signature from a tornado on the ground. More details from NOAA: "This week, the National Weather Service completed the dual-polarization technology update in Brownsville, Texas – concluding the 122 NWS radar site upgrades throughout the country. This new advanced technology is helping federal weather forecasters more accurately track, assess and warn the public of approaching high-impact weather. Dual-polarization is the most significant enhancement made to the nation’s federal weather radar system since Doppler technology was first installed in the early 1990s. Dual-pol radar sends and receives both horizontal and vertical pulses, which produces a much more informative picture of the size and shape of the objects in the sky. This provides meteorologists the ability to distinguish between rain, snow, hail and non-weather items like wildfire smoke plumes, birds and insects. Conventional Doppler radar only has a one-dimensional view making it difficult to tell the type of precipitation or object in the sky..."
Is Air Pollution Contributing To Hardened Arteries? Some of the research was done in St. Paul, among other U.S. cities. Here's an excerpt from a story at Time Magazine: "Smog and car exhaust can take a toll on the heart, and the latest research explores how. Previous studies have shown an association between badly polluted air and a heightened risk of heart attack stroke, and researchers have started to investigate how pollutants could exert such harm. Some have documented the increased inflammation that pollution can trigger, as well as changes in blood pressure and the activity of clotting factors in the blood that could promote heart heart disease. The latest research, published in the journal PLOS Medicine, found that exposure to air pollution may increase heart attacks and strokes by accelerating the process of atherosclerosis..."
More Welcome Signs of Spring. WeatherNation TV meteorologist Todd Nelson snapped this photo in St. Michael Sunday evening as showers and a few T-showers blossomed, forming out ahead of a weak cool front. Note the rain shaft illuminating a small rainbow. Nice.
81 F. high in the Twin Cities Sunday.
September 29, 2012: last time it got this warm in the metro area (82F).
64 F. average high for April 28.
51 F. high on April 28, 2012.
Heat Spike. From 4" snow on a Tuesday morning to 81F 5 days later? Even by Minnesota standards that's impressive. Sunday highs ranged from 56 at Grand Marais to 68 Duluth (6" snow left) to 77 St. Cloud, 81 Twin Cities and a balmy 83 at Redwood Falls.

Climate Change: Extreme Weather, Insurance Companies And Taxpayers. Here's a video and excerpt from The Energy Collective: "This NRDC video discusses the costs of extreme weather events, which in 2012 totaled one percent of the nation’s gross domestic product. Insurance companies are “under water” in more ways than one and the US taxpayer ended up paying what is essentially a “climate disruption” of 2.7 percent more than the total collected in sales taxes for 2012..."
Climate Change: It's Real And It's Here, Expert Says. Here's a clip from htrnews.com: "Twenty-five years ago, James Brey was a climate change denier. “Then the evidence began to mount,” he said. “At some point, doubts began to diminish and the conviction began to grow.” Today, Brey, American Meteorological Society education program director, is a believer. You might say he was preaching to the choir Thursday night when he spoke to a group of about 50 concerned citizens gathered in the Riverview Room at the Wisconsin Maritime Museum for his climate change workshop. The workshop was presented by Friends of the Manitowoc River Watershed in conjunction with the Lakeshore Natural Resources Partnership..."
China Becoming Global Climate Change Leader. There is little "debate" about the science of climate change in China, which is a bit ironic. They realize they have a problem, and they're taking concrete steps to address those problems, according to this article from AFP and Google News: "China is rapidly assuming a global leadership role on climate change alongside the United States, a new study said Monday, but it warned greenhouse gas emissions worldwide continue to rise strongly. The report by the independent Australian-based Climate Commission, "The Critical Decade: International Action on Climate Change" presents an overview of action in the last nine months. It was released on the same day as a fresh round of UN talks were to start in Bonn on boosting action on climate change -- a two-decade-long process that has been dogged by procedural bickering and defence of national interests. The study found that every major economy had policies in place to tackle the issue, but China was at the forefront in strengthening its response, "taking ambitious strides to add renewable energy to its mix". "China is accelerating action," said Tim Flannery, the co-author and a key figure at the Climate Commission, which brings together internationally-renowned scientists, as well as policy and business leaders..."

The Oddly Tepid Political Fight Over Global Warming. Here's an excerpt from a story at The Atlantic Wire: "Yesterday afternoon, a panel of experts was convened by a House subcommittee to discuss taking action on climate change. Earlier, the heavy machinery that was once Barack Obama's campaign team, Organizing For America, began a new push to hold politicians to task for having not yet done anything on the issue. The odds are good that you didn't know that either of these things happened. The urgency with which scientists and the environmental community looks at global warming has still not been translated to Capitol Hill — or to the rest of America. The House hearing, led by Republican Rep. Chris Stewart of Utah, was never likely to create a massive shift in the politics of the climate. Stewart has long denied a strong human role in warming, writing an opinion piece for the Salt Lake Tribune earlier this month in which he claims that "the science regarding climate change is anything but settled." (Scientists disagree.) Stewart's essay did have one positive outcome: the Tribune was also the only media outlet to cover yesterday's hearing..."

On Climate, GOP Turns From Concern To Denial. Here's a clip from an Op-Ed at The Houston Chronicle: "...How did the conservative movement travel so far, so fast? How did a party that prided itself on reason become a hotbed of scientific denial? The transformation has paralyzed U.S. policymaking and squandered decades that could have been spent weaning the world from fossil fuels. Twenty-three years after Thatcher urged action, the United States has no policy on climate change, even as its effects are evident and the window for action is closing. In 1997, "There was no difference between the way Democrats and Republicans across America viewed the issue," said Ed Maibach, executive director of George Mason University's Center for Climate Change Communication, a research center. Two out of three Democrats and two out of three Republicans believed that climate change was both real and serious. "Somewhere along the way, conservatism became, 'I've got a God-given right to drive my SUV wherever I want to go, and we'll send somebody else's kids to the Middle East to fight for it," said former South Carolina Rep. Bob Inglis, a Republican who lost his 2010 primary election over global warming and now runs the Energy and Enterprise Initiative, where he is pushing for a price on carbon pollution..."
The Drought-Stricken Midwest's Floods: Is This What Climate Change Looks Like? Here'san excerpt from a story at The Atlantic Wire: "...In other words, a warmer atmosphere from climate change likely yields greater extremes in weather. This syncs with the draft report issued by the government's National Climate Assessment Development Advisory Committee last year. That report predicted the following for the Midwest: "longer growing seasons and rising carbon dioxide levels will increase yields of some crops, though those benefits will be increasingly offset by the occurrence of extreme events such as heat waves, droughts, and floods." That prediction was meant to be borne out over the next several decades. What it predicted, though, has already been seen over the course of six months..." (photo: AP).
As CO2 Concentrations Near Ominous Benchmark, Daily Updates Begin. Scientific American has the story - here's an excerpt: "...Scientist Ralph Keeling wants this generation to remember when atmospheric concentrations of carbon dioxide reached 400 parts per million, because of humans. "I hope that many people out there in the decades to come will say, 'Gosh, I will remember when it crossed 400,'" he said. That's why Keeling and his employer, the Scripps Institution of Oceanography at the University of California, San Diego, have launched a website that will provide daily updates on atmospheric CO2 concentrations, measured at Hawaii's Mauna Loa Observatory..."

CO2 On Trial: If Things Had Worked Out Better. Here's an excerpt of an important article, an explanation of how climate science has been turned into a perverse mock "trial". Michael Tobis argues that we need to grow up, and recognize our limits in this story at medium.com: "...The fact is that we are entering an age of new and unprecedented limits. We can still have a happy future, human achievement and human dignity can continue its broad historical progress, and we can still have a lot of fun. But we have to recognize new limitations. The emergence of limits is unfortunate. It's costly. It's ill-timed. But preserving a stable environment is an ethical responsibility like none that has preceded it. We need people to understand not only that CO2 is a global problem, but that it's just the first in a series, as we make the transition from an open frontier world to spaceship earth. As a brand of soap, this is a hard sell. We have to sell the idea of a widespread set of changes in behavior, a new set of ethical constraints, and a substantial increase in the complexity and scale of governance. There are serious risks and costs involved, but avoiding this responsibility will yield something much worse..."
Global Warming Accelerated Last 15 Years. Here's an excerpt from Doug Craig's terrific Climate of Change blog at Redding.com: "...And a new study of ocean warming published last month in Geophysical Research Letters by Balmaseda, Trenberth, and Källén reached several conclusions:
• Completely contrary to the popular contrarian myth, global warming has accelerated, with more overall global warming in the past 15 years than the prior 15 years. This is because about 90% of overall global warming goes into heating the oceans, and the oceans have been warming dramatically.
• As suspected, much of the 'missing heat' Kevin Trenberth previously talked about has been found in the deep oceans. Consistent with the results of Nuccitelli et al. (2012), this study finds that 30% of the ocean warming over the past decade has occurred in the deeper oceans below 700 meters, which they note is unprecedented over at least the past half century..."
2.24" liquid precipitation predicted for MSP by Friday. Rain today, ice tonight, ice changing to snow tomorrow, lingering into Thursday night.
4-8" slushy snow expected Twin Cities metro, maybe more far northern/western suburbs. Definitely plowable by Thursday.
High water content may result in downed trees and powerlines at the height of the storm. I wouldn't be surprised to see reports of power outages Wednesday and Thursday.
6.7" If we pick up at least 6.7" (very possible) this will be the heaviest April snow since 2002.
13.6" Most snowfall in a 24 hour period in April (April 14, 1983). I remember it well.
Winter Storm Watch in effect as of this evening - it may be upgraded to a Winter Storm Warning, even for the metro.
Just the Messenger
May I be excused, please?
This might be a good time to drive south to a slightly warmer, more meteorologically hospitable spot, like Dubuque.
A friend of mine, Tim, reports local fast-ball softball teams are driving as far south as Illinois and Kansas City to find (thawed) ball fields to play on. Our stunted spring has many of us in a funk, and things are about to get even more "interesting".
A slow moving storm tracking across the Plains will spray a fire-hose of Gulf moisture northward - flooding rains for the Midwest & heavy wet snow from the Upper Mississippi Valley into the Dakotas, where some 20-30 inch amounts are predicted. Good grief. A cold rain today mixes with ice tonight and Wednesday, a plowable (4-8"+) pile of slush may reach the metro area from Wednesday into Thursday; heaviest amounts on lawns, fields and dazed robins.
Thursday may be the most challenging travel day.
Note to self: I shouldn't have taken off my snow tires - but at least I left my driveway stakes in.
It's baffling: the maps look like something out of early March. The most snow from an April storm? 13.6" on April 14, 1983. If we pick up 6.7" (possible) it would be the most April snow since 2002.
Biggest Single Day April Snowfalls In The Twin Cities? I was really hoping not to have to include this data from the Minnesota State Climatology Office:
Rank Value Ending Date
1 13.6" 4/14/1983
2 8.9" 4/7/1923

Something For Everyone. Everything except sunshine and 70s. Flood watches and warnings for Wisconsin, a Winter Storm Watch for the Twin Cities, and Winter Storm Warnings west of St. Cloud. Details on the Winter Storm Watch from the Twin Cities NWS:
...WINTER STORM WATCH REMAINS IN EFFECT FROM TUESDAY EVENING THROUGH THURSDAY AFTERNOON... A WINTER STORM WATCH REMAINS IN EFFECT FROM TUESDAY EVENING THROUGH THURSDAY AFTERNOON. * TIMING: LIGHT RAIN WILL TRANSITION TO A WINTRY MIX OF PRECIPITATION ON TUESDAY EVENING AND CHANGE OVER TO SNOW LATE WEDNESDAY. * MAIN IMPACT: SNOW ACCUMULATIONS OF 6 INCHES OR GREATER... MAINLY BETWEEN WEDNESDAY EVENING AND MID DAY THURSDAY. * OTHER IMPACTS: SMALL ICE ACCUMULATIONS DUE TO SLEET AND LIGHT FREEZING RAIN ON TUESDAY EVENING AND WEDNESDAY. PRECAUTIONARY/PREPAREDNESS ACTIONS... A WINTER STORM WATCH MEANS THERE IS A POTENTIAL FOR SIGNIFICANT SNOW...SLEET...OR ICE ACCUMULATIONS THAT MAY IMPACT TRAVEL. CONTINUE TO MONITOR THE LATEST FORECASTS.
Hey...It'll Melt. Last night I complained about the snow to my wife of 28 years. She told me to shut up. "It'll melt", she said. True enough. The GFS is still going nuts, showing some 12-16" amounts, which could happen, if there is no wintry mix (sleet and freezing rain); if precipitation falls as ALL SNOW. This could happen, but I still expect some rain, sleet (ice pellets) and freezing rain to mix in, especially today and the first half of Wednesday, which will keep amounts down in the far more reasonable range of 5-8", maybe 10" far northern suburbs. But hey, it'll melt.
I Can't Quite Believe It Either. I want to dismiss this as utter nonsense. It's the second week of April! As far as the atmosphere is concerned it's the first week of March. There's enough cold air in place for some 1-2 foot snowfall amounts from eastern Wyoming into South Dakota; maybe 18" for west central Minnesota and a cool foot for St. Cloud. The NAM is hinting at 4-8" for the immediate MSP metro by Friday morning, with the heaviest amounts north and west of town (on lawns and fields). I feel the sudden urge to drive (run?) south - as fast as I can.
Potential For Glaze Ice Tonight. I expect a cold rain today, but surface temperatures should dip just below 32F later tonight, allowing rain to freeze into glaze in time for rush hour Wednesday morning. Plan on leaving a lot more time to get around Wednesday and Thursday.
WSI RPM Model. WSI's high-resolution 12km. RPM model is in pretty good alignment with the NAM, suggesting 8-10" across the MSP metro, most of that coming Wednesday PM into Thursday, when temperatures in the lowest mile of the atmosphere bottom out. Some 24"+ snowfall amounts are forecast west of Sioux Falls. What month is this again?
One Of The Biggest Snowfalls of Winter - Coming in "Spring". No, the irony isn't lost on me. The 00z NAM shows a major storm spinning up over the Plains, moving slowly to the east-northeast, tapping moisture from the Gulf of Mexico, taking a track favorable for heavy wet snow from South Dakota into Minnesota and Wisconsin.
Storm Track. NOAA models show a track well south of Minnesota, ensuring a steady supply of cold air at the height of the storm, Wednesday into Thursday. The slow forward motion of the storm will help to contribute to excessive precipitation amounts: rain and heavy wet snow.
Plenty Of Moisture. I was hoping for rain (to alleviate the drought), but we'll wind up with more snow than rain this week. Models suggest 1.5 to 2.5" liquid by Friday morning, more (rain) Sunday of next week. The good news? I feel more confident than ever that, based on the cool, wet pattern we're stuck in, the drought will ease over much of Minnesota by June.
Euro-Trash. Sadly, I think the ECMWF (European) model is probably on track to verify; hinting at 1.25" liquid Wednesday and Thursday, much of that moisture falling as heavy, wet snow. With high water content in the snow I wouldn't be surprised to hear reports of downed tree limbs, even some power outages at the height of the storm. It should be warm enough for rain showers Sunday, readings reach the 50s to near 60 by the middle of next week. Right.
Tracking A Freak April Storm. Here's a YouTube video that delves into the reasons for this week's March-like storm, and why rainfall and snowfall amounts may be very significant, some of the highest of the winter season: "Calendar says April 8th, but the weather maps are much more in line with what you would see in early March. 20-30" snowfall amounts possible along with the potential for a few large violent tornadoes. Millions of people will be impacted this week. Are you one of them? Watch what Meteorologist Paul Douglas has to say about this freak April storm."
Here is an excerpt from an Alerts Broadcaster briefing issued to our corporate clients late Monday:
I'm sitting here, in a Monday funk, mourning the apparent death of spring, at least over the Plains and Upper Midwest. The calendar insists that its April 8, but as far as the atmosphere is concerned it's March 1, give or take. An unusually intense storm (for the second week of April) will impact the central USA with heavy wet snow, heavy rain capable of urban and river flooding, and deeper into the warm, humid air, a significant severe storm outbreak, with a potential for a few large, violent tornadoes: central Plains today and Tuesday, pushing into the Mississippi Valley and Mid South by Wednesday and Thursday.
* Near-blizzard conditions are possible in the Denver area Tuesday; where as much as 5-9" of snow will fall. Expect delays and cancellations at KDEN, especially tomorrow.
* Models print out some 20-30" amounts across South Dakota, with plowable snows pushing across Minnesota into Wisconsin Wednesday and Thursday.
* Chicago may pick up 3" of rain by Thursday, complicating stream and river flood forecasts - I expect some level of urban flooding as well.
* A few large, violent, long-track tornadoes are possible tomorrow from Austin and Dallas to Kansas City. By Wednesday the threat shifts to Shreveport, Little Rock, Memphis, St. Louis and Louisville. Details:
3-5 Week's Worth of Rain by Thursday. The NAM model prints out very heavy rainfall amounts for the Upper Midwest and Great Lakes, as much as 2-3" or more of liquid water. Most of that water will fall as heavy wet snow over the Plains and portions of the Upper Midwest.
Confirmation. The models are coming into alignment, showing the heaviest snowfall amounts from Nebraska into South Dakota and southwestern Minnesota, where some 12"+ amounts seem imminent. This could still be a plowable snowfall for the Twin Cities by Wednesday and Thursday, with some 5-10" amounts extending toward Wausau, Appleton and the Green Bay, Wisconsin markets.
Mile High Mess. Snow arrives tonight in Denver, peaking tomorrow, when an increase in wind speed may trigger near-blizzard conditions. I'm comfortable (wrong word) predicting 5-9" for the Denver area by the time snow tapers Wednesday.
Blizzard Potential Index. One of the many value-added models we run here at Alerts Broadcaster is the BPI, the Blizzard Potential Index, factoring in snowfall rates, wind speeds and predicted visibilities. The worst of the storm along Colorado's Front Range is forecast to come Tuesday afternoon.
Remarkable Extremes. I don't think I've ever seen this. Alerts Broadcaster models predict highs topping 100F over southern Texas, while holding in the 20s over Colorado and New Mexico over the next 72 hours. The resulting temperature gradient will help to spin up an unusually intense storm over the Plains states.
On Track For A Significant Severe Storm Outbreak. Although not as expected to be as violent as outbreaks in 2011, the stage is set for supercell thunderstorms capable of large, long-lasting tornadoes capable of significant destruction. The risk is greatest tomorrow from Dallas to Oklahoma City and Wichita - the threat shifts into the Mississippi Valley by Wednesday.
Friday Storm Potential. A few severe thunderstorms are likely in the Atlanta area late Thursday, possibly pushing into D.C., the Delaware Valley and New York City by Friday afternoon. Although the potential for tornadoes will be small, some storms may produce large hail and damaging straight-line winds. Friday's PM commute may be a real mess across the Northeast.
Summary: I've seen a lot of things in 40 years of meteorology, but I can't remember the last time I saw 20-30" snowfall amounts during the second week of April. Portions of the High Plains may be temporarily shut down, starting tomorrow, spilling over into Thursday. Disruptions to travel and the power grid may be considerable, especially from Denver into Nebraska and South Dakota. Ice changing to snow will create poor to treacherous travel conditions over Minnesota and Wisconsin. The worst conditions at KMSP (Twin Cities) and KMKE (Milwaukee) will probably come Thursday. The slow forward motion of the storm will prolong rainfall across the Midwest, accelerating run-off and stream/river flooding, especially southern Wisconsin into the Chicago and Indianapolis area by midweek.
Ask Paul. Weather-related Q&A:
Is there an easy place to get searchable records for actual snowfall totals by location and date? Looking to compare each month of the 2012-2013 Winter season in my neck of the woods (or stretch of the prairie - I'm on the edge)
I stumbled around NOAA for awhile and ended up chasing my tail.
I asked climate guru Pete Boulay at the Minnesota Climatology Working Group for his advice - here was his answer:
"You can find the closest snow data to your location by going here:
It appears as though the closest place with at least partial data is site 210643 (Bemidji Airport)."

Climate Change And Turbulence Link? Warmer Air Could Mean A Bumpier Airplane Ride. Great. This is just what I want to read before getting onto a flight. I'd like a seat in the Black Box please. Here's an excerpt from Huffington Post: "Transatlantic airline passengers might expect to stay seated with their seatbelts securely fastened more often in the future, according to new research that finds climate change could lead to more airplane turbulence. By the middle of the century, turbulence strength over the North Atlantic flight corridor could increase between 10 percent and 40 percent, and turbulence frequency could jump between 40 percent and 170 percent, according to the new study published online today (April 8) in the journal Nature Climate Change. The increase could have major implications for the airline industry, as approximately 600 flights a day make the North Atlantic transit from Europe to North America and back. The study researchers focused on clear-air turbulence, the sort of bumps that occur even in the absence of clouds or mountains (which can also give airplane passengers a rocky ride). Clear-air turbulence occurs when masses of air moving at different speeds collide in the atmosphere, making it invisible to the naked eye and nearly impossible to detect using radar or satellite..."

A favorable outcome for Aereo and the Hopper in court would push TV operators to dramatically reshape themselves. It could even force them to trade in their broadcast towers and become cable channels alongside networks such as Bravo, AMC and ESPN, says Garth Ancier, who has been the top TV programmer at Fox, NBC and the WB networks.
“They won’t have a choice,” Ancier said. “When someone attacks your business, sometimes you do something radical...”

Breaking News (Literally). NOAA Confirms Early Break-Up. Here's a video and excerpt of a story at Climate Denial Crock of the Week: "...A series of intense storms in the Arctic has caused fracturing of the sea ice around the Beaufort Sea along the northern coasts of Alaska and Canada. High-resolution imagery from the Suomi NPP satellite shows the evolution of the cracks forming in the ice, called leads, from February 17 — March 18 2013. The general circulation of the area is seen moving the ice westward along the Alaskan coast “Intense storms” are not an unheard of thing in the arctic. What’s new is that the ice is so fragile that normal storm activity is breaking it up much earlier than has been seen in the past..."
Simpler, Cheaper Way To Make Methanol Fuel Using CO2 and Sunlight. Find a revenue-neutral way to price carbon pollution (one that doesn't make government bigger) then step back and let the markets do what they do best: innovate. Here's an excerpt of a fascinating story at gizmag.com: "Most previous methods of producing methanol from carbon dioxide have involved lots of electricity, high pressures and high temperatures, and used toxic chemicals or rare earth elements like cadmium or tellurium. A team of researchers at the University of Texas at Arlington (UTA) has developed a new method they claim is safer, less expensive, and simpler than current approaches and can be scaled up to an industrial scale to allow some of the CO2 emitted from electrical power plants to be captured and converted into a useful fuel..."

Oceans May Explain Slow-Down In Climate Change. 90-93% of warming is going into the world's oceans, the balance warming the atmosphere and melting ice. Here's an excerpt from Yahoo News: "Climate change could get worse quickly if huge amounts of extra heat absorbed by the oceans are released back into the air, scientists said after unveiling new research showing that oceans have helped mitigate the effects of warming since 2000. Heat-trapping gases are being emitted into the atmosphere faster than ever, and the 10 hottest years since records began have all taken place since 1998. But the rate at which the earth's surface is heating up has slowed somewhat since 2000, causing scientists to search for an explanation for the pause. Experts in France and Spain said on Sunday that the oceans took up more warmth from the air around 2000. That would help explain the slowdown in surface warming but would also suggest that the pause may be only temporary and brief..."

Climate Change Will Threaten Wine Production, Study Shows. Coffee, chocolate, now wine? Say it isn't so. Here's an excerpt from The Guardian: "Bid adieu to Bordeaux, but also, quite possibly, a hello to Chateau Yellowstone. Researchers predict a two-thirds fall in production in the world's premier wine regions because of climate change. The study forecasts sharp declines in wine production from Bordeaux and Rhone regions in France, Tuscany in Italy and Napa Valley in California and Chile by 2050, as a warming climate makes it harder to grow grapes in traditional wine country. But also anticipate a big push into areas once considered unsuitable. That could mean more grape varieties from northern Europe, including Britain, the US north-west and the hills of central China..."

Why We Support A Revenue-Neutral Carbon Tax. Here are two prominent Republicans, George Schultz and Gary Becker, proposing to tax a known pollutant, but in a way that encourages economic growth and innovation in the marketplace. The Wall Street Journal has the story; here's an excerpt: "Americans like to compete on a level playing field. All the players should have an equal opportunity to win based on their competitive merits, not on some artificial imbalance that gives someone or some group a special advantage. We think this idea should be applied to energy producers. They all should bear the full costs of the use of the energy they provide. Most of these costs are included in what it takes to produce the energy in the first place, but they vary greatly in the price imposed on society by the pollution they emit and its impact on human health and well-being, the air we breathe and the climate we create. We should identify these costs and see that they are attributed to the form of energy that causes them. At the same time, we should seek out the many forms of subsidy that run through the entire energy enterprise and eliminate them. In their place we propose a measure that could go a long way toward leveling the playing field: a revenue-neutral tax on carbon, a major pollutant..."
Study: "Working Together" Won't Fix Climate Change. It's in our DNA to collaborate on big challenges, right? Not so much, argues this article at Salon; here's an excerpt: "When it comes to climate change, we’re all in this dilemma together, and forcefully addressing it will require collaboration and cooperation. A stirring sentiment, but if you’re looking to spur white Americans to action, it’s actually counterproductive. That’s the conclusion of a Stanford University research team, which found invoking the idea of interdependence undermined the motivation of European-American students to take a course in environmental sustainability. The researchers, led by MarYam Hamedani of Stanford’s Center for Comparative Studies in Race and Ethnicity, argue that in mainstream European-American culture, independence functions as a “foundational schema” — that is, an underlying design or blueprint that guides behavior..."

Schwarzenegger: California's Silent Disaster. Here's an excerpt of an Op-Ed in the L.A. Times from the former governor of California: "I will always remember the day I woke to the news that more than 2,000 fires were burning in California. I thought I must not have heard correctly. Two thousand fires? How could that be? In the end, the state's brave firefighters, joined by contingents from out of state, won the battle. But not before 11 emergency declarations were issued and more than 400,000 acres burned. Countless lives and livelihoods were ruined. Today, there's a new disaster looming, and although it's not as riveting or dramatic as walls of flames and billowing black smoke, it needs our immediate attention. The draft National Climate Assessment, now being circulated for comment and scheduled for release this year by the U.S. Global Change Research Program, presents a sobering vision of the world that awaits us if we don't act..."

2.07" liquid precipitation by Thursday morning. 00z NAM model.
Plowable snowfall can't be ruled out, even in and around the MSP metro, Wednesday into Thursday.
2" average April snowfall (latest 30 year climate data).
21.8" snow fell on the metro area in April, 1983. Good grief.
"This isn't funny Paul - we're not Duluth". That was my Saturday evening; more stares & glares than friendly smiles. Our tortured spring hits rock-bottom later this week; the second week of April's weather looking like something out of early March.
An intense storm spins up tornadoes from Kansas City to Dallas, while 1-2 feet of snow buries the Dakotas. I expect enough warm air aloft for rain into Tuesday evening. And then it gets interesting.
Models suggest enough sub-freezing air in the lowest few thousand feet of the atmosphere for some freezing rain (glaze ice) and sleet (ice pellets) by Wednesday- maybe a few inches of slush on lawns & fields by Wednesday and Thursday. Plowable? Perhaps - especially outside the MSP metro area.
It's too early to speculate on amounts, but whatever falls should be pretty much gone by Friday afternoon or Saturday. The sun is too high in the sky for slush to linger.
1-2" of precipitation may fall this week close to home, complicating the flood forecast - the ground is still frozen, making run-off and rapid urban, stream and river flooding a greater risk.
A few months ago I predicted a late spring, a slow easing of drought, and a cooler, wetter, more severe summer. I stand by that prediction.
Short-term I may need a better disguise and more therapy: long-range models hint at another slush-storm in one week.
I hope I'm wrong.
A Potentially Very Wet Week. Models are printing out well over 1" of liquid precipitation by Wednesday; mostly rain for the Twin Cities, but a wintry mix can't be ruled out by midweek. The local NWS office is predicting 1.2" by Wednesday midday. Graphic: Iowa State.
May I Please Be Excused? I'm tempted to drive to MSP International and hop the first southbound flight. Anywhere. Not sure I want to be here Wednesday and Thursday. The natives are already restless - if we do pick up a few inches of slush by Thursday that might just push people over the edge. Rain today, Tuesday and the first half of Wednesday. If we do see a wintry mix it would probably come from Wednesday PM into Thursday. Saturday looks dry, a cold rain pushing back into Minnesota Sunday - right now it looks warm enough for rain, at least in the Twin Cities, based on ECMWF guidance.
Skew-T. The projected temperature sounding (in red) by 2 pm Wednesday shows a relatively shallow layer of sub-freezing air in the lowest few thousand feet of the atmosphere. Warm ari aloft will melt rain, which may re-freeze into sleet or even wet snow by Wednesday afternoon and night.
Latest from Alerts Broadcaster:
A major storm is spinning up for the central USA, capable of impacting towns from Denver to Dallas to the Twin Cities from Monday thru Thursday of this week with a wide variety of potentially disruptive weather:
- Significant tornado outbreak possible the first half of this week. Tuesday looks like the most violent day from Dallas and Oklahoma City to Kansas City and St. Louis, with a few large, violent, long-track tornadoes expected.
- Heavy wet snow will fall from Wyoming and Colorado's Front Range across the Dakotas, potentially plowable amounts of slush into part of Minnesota, Wisconsin and Lower Michigan by Wednesday and Thursday. Yes, this is unusual for the second week of April.
- Flood risk. The ground is still frozen over most of the Upper Midwest - any heavy rain will run off into streets, streams and rivers. I expect river flooding (and urban flooding) to be on the increase over the next 72 hours. Details:
Latest Watches. Denver may pick up as much as 5-10" of snow from Monday night into Tuesday. Blizzard Watches are posted for portions of Colorado, a Winter Storm Watch from the Central Rockies into the Dakotas and western Nebraska. Severe thunderstorms are already popping up over the Plains; the potential for severe weather will increase into Tuesday.
Tuesday Severe Storm Potential. Severe storms are likely over the Plains Monday into Wednesday, but I suspect Tuesday will be the busiest day as dynamics converge for a few large, potentially violent tornadoes from Austin and Dallas northward to Tulsa, Wichita, Kansas City, St. Louis, even Des Moines. The timing is right - I expect SPC to upgrade the risk to "moderate" within 24 hours.
Facilities On Alert. There is a 30% probability of severe weather (58 mph+ winds and/or 1" hail or larger) within 25 miles of metropolitan areas from Dallas and Oklahoma City to Kansas City and Topeka on Tuesday. I expect numerous Tornado Watches and Warnings, with the greatest potential for damaging winds between 3 pm and 8 pm.
Cities Potentially Impacted Tuesday. Here is a close-up of the significant severe threat area, which includes Waco, Wichita Falls, Wichita, Springfield and the suburbs of Kansas City.
Serious Slush Potential. Chicago should avoid any snowy headaches, but enough snow to shovel and plow is expected from Denver into South Dakota and western and central Minnesota. A few inches of slush may accumulate on lawns and fields in the Twin Cities Wednesday night into Thursday - most freeways should stay wet.
Sliding Into A Much Wetter Pattern - Growing Flood Risk. The GFS model is printing out impressive rainfall amounts with this storm by Friday evening, as much as 4" from near Omaha and Lincoln to Des Moines; some 2-3" amounts near Milwaukee, Chicago and Detroit. This may complicate river flooding later this week. Areas prone to urban, stream and river flooding will want to keep a close eye on conditions and have contingency plans ready to go.
Flood Update. Major flooding is already underway near Devil's Lake, North Dakota, and along the East Fork of the Black River in Wisconsin. I expect river flooding to intensify later this week - the greatest concern is along the Red River flowing through Fargo, where a crest is still probably 1-2 weeks away. Urban flooding later this week is most likely from Des Moines into the Twin Cities, Milwaukee and possibly the greater Chicago area.
Summary: The calendar says April, but the weather maps still look like something out of early March. An unusually intense spring storm will elevate the risk of heavy wet snow (western Plains and Upper Mississippi Valley), significant river flooding from some 1-4" rainfall amounts, and a substantial risk of severe storms, hail, damaging winds and a few large, violent tornadoes by Tuesday from Dallas to Kansas City. After peaking in the 60s earlier today Denver will see 5-10" snow Monday night into Tuesday; I expect numerous delays and cancellations at KDEN Tuesday. We'll watch the storm unfold and provide updates as needed.
Impact Based Warnings. Minnesota is one of 14 states that will see new, enhanced wording of tornado warnings, to try to better reflect and communicate the risks to consumers in the potential path. Details from NOAA's Central Region: "An experimental National Weather Service warning enhancement will be used across much of the central U.S. this thunderstorm season (beginning April 1). This is an expansion of a smaller NWS experiment that began in Kansas and Missour in 2012. The Impact Based Warning (IBW) experimental product is an effort to better communicate severe weather threats within National Weather Service warnings. While the basic function of Severe Thunderstorm and Tornado warnings will remain the same, additional enhanced information will be provided within the warning to provide additional expected "impact" information. The goals are to provide more information through the warnings in order to facilitate improved public response and decision making, and to better meet societal needs in the most life-threatening weather events. This effort is in response to key findings from recent service assessments of devastating tornadoes in 2011, particularly the EF-5 tornado in Joplin, MO..."

Weather, Disaster Agencies Turn To Twitter, Facebook, YouTube. Bill McAuliffe at The Star Tribune takea look at The Star Tribune takes a look at social media's impact on weather coverage, specifically severe storm tracking and communication. As I say in the article, I suspect it's a mixed blessing: nice to have more information, but be sure you're following "trusted sources" to get reliable, actionable information. Here's an excerpt: "With the season for quick-hitting storms about to barge into Minnesota, social media are about to become a key news tool. Indeed, public agencies concerned with natural disasters are glomming onto social media like so many teenagers, attracted to its instant, two-way connectivity. “It’s fast. It’s direct. It enhances our ability to deliver the message,” said Bruce Gordon, director of communications for the Minnesota Department of Public Safety, whose 12 public information officers post breaking news, safety tips and even human interest stories on Facebook, Twitter and YouTube..."

When It Rains It Pours: Study Confirms Climate Change Will Keep Driving More Intense Precipitation. Here's a clip from a story at Think Progress: "...The NOAA study, published in Geophysical Research Letters, found that extreme precipitation events will become more intense this century as the globe continues to warm. Extra moisture expected from that warming will be the dominant factor fueling this increase in extreme precipitation, with a 20 to 30 percent more precipitation in the Northern Hemisphere by 2099.
The paper looked at three factors that go into the maximum precipitation value possible in any given location: moisture in the atmosphere, upward motion of air in the atmosphere, and horizontal winds. The team examined climate model data to understand how a continued course of high greenhouse gas emissions would influence the potential maximum precipitation. While greenhouse gas increases did not substantially change the maximum upward motion of the atmosphere or horizontal winds, the models did show a 20-30 percent increase in maximum moisture in the atmosphere, which led to a corresponding increase in the maximum precipitation value..."
Killing Pipeline Is Key To Climate Change Fight. Here's an excerpt of an Op-Ed written by climate scientist James Hansen in The Register-Guard: "...The draft review suggests the climate impacts of the pipeline are limited because the project will not substantially “induce growth in the rate of extraction in the oil sands.” This narrow analysis misses the mark. Researchers now say that the Alberta tar sands contain 360 to 510 billion tons of carbon — more than double that of all oil burned in human history. While only a fraction is considered economically recoverable right now, we humans are genius at finding new and better ways to dig junk out of the ground. Digging begets more digging. Once the big spigot is open, TransCanada will have every incentive to milk the massive tar sands basin for all it is worth..." (image: Clean Technica).
Getting Serious About A Texas-Size Drought. Here's an excerpt from The New York Times (subscription may be required): "...Other desperately dry states in the Midwest and West are facing similar challenges. Drought has hurt farmers in New Mexico and reduced California’s crucial mountain snowpack. Even the Great Lakes are at worryingly low levels. Drought conditions in the western half of the country are likely to persist at least through June, federal forecasters have warned. Over time, as the effects of climate change become more pronounced, hotter weather and longer dry spells will continue to threaten water supplies that are essential for development. Already the drought has led to consideration of wild, expensive ideas, like piping water hundreds of miles from the Missouri River to the parched Colorado River basin. Water traditionally has been mostly a state or local issue because communities draw supplies from nearby rivers or aquifers. But increasingly it is becoming a national one. Economies will rise and fall on the availability of water, whose price is inexorably marching upward. Litigation and rural-urban water conflicts are likely to intensify throughout the West and Midwest..."

How U.S. Energy Policy Fails To Address Climate Change. The Christian Science Monitor reports; here's an excerpt: "What never gets asked and answered definitively in the policy debate is this: What should our ultimate goal be and when should we aim to achieve it? The first part of the question has elicited so many answers from so many constituencies that I may not be able to represent them all here. But here is an attempt to categorize the main lines of thinking concerning the country’s energy goals:

Global Warming: 1,600 Years Of Ice In Andes Melted In 25 Years. Here's an excerpt from frenchtribune.com : "Providing one of the signs of global warming, glacial ice in the Peruvian Andes has started melting. A structure that took 1,600 years to build has fallen into the grip of high temperatures and melted within 25 years. The research has been conducted by Lonnie G. Thompson, the Ohio State University glaciologist. According to him, his team has worked from time to time on the Quelccaya ice cap for decades. Findings have been published in a paper that has been released online. Global warming is one of the results of man-made activities. This recent report has highlighted that the problem of global warming has reached its peak. This time the proof has been provided by margins of the Quelccaya ice cap in Peru..."
Even Doubter Wants To Prepare For Global Warming. Mother Nature News has the article; here's the intro: "Some still insist that climate change is a hoax, but the vast majority of Americans believe the globe is warming, a new survey finds — and they want to prepare for the worst. In fact, even 60 percent of climate-change doubters favored preparations, the survey found. Researchers collected opinions between March 3 and March 18 via an online questionnaire, using a nationally representative sample of 1,174 American adults, both English and Spanish speaking. The survey asked about climate-change beliefs and support for adaptation strategies to help coastal areas cope with the rising sea levels and frequent, intense storms that a warmer world could bring. The results showed that 82 percent of Americans are in favor of preparation..."

Federal Study: Global Warming Means More "Extreme" Rains. Basic physics: warm up the atmosphere, even by a few degrees, and you increase the capacity of the sky overhead to hold more water vapor (which is itself another greenhouse gas). The result? More fuel for extreme rains (and snows). The Hill has the story; here's the intro: "Global warming will make cases of “extreme” rainfall even more intense and worsen flood risks, federal researchers say in the latest warning that climate change will likely worsen violent weather. A new federally led study explores how growing amounts of atmospheric water vapor due to global warming will affect what is called probable maximum precipitation. The report, released by the National Oceanic and Atmospheric Administration, forecasts an “accelerated water cycle with heavier extreme rains.” The study shows “a 20-30 percent expected increase in the maximum precipitation possible over large portions of the Northern Hemisphere by the end of the 21st century if greenhouse gases continue to rise at a high emissions rate,” NOAA said..."

Rising Seas Swallow 8 Cities In These Climate Change GIFS. Mashable has the story; here's an excerpt: "Climate change and global warming may cause sea levels to rise and flood coastal cities across the world. Over the past century, the Global Mean Sea Level has risen by 4 to 8 inches. And according to estimates by the National Oceanic and Atmospheric Administration (PDF), it will keep rising between 8 inches and 6.6 feet by 2100. How will the world look if that happens? In November of 2012, The New York Times published interactive maps displaying the effects of the sea level rising, in a series titled "What Could Disappear?" The maps show how much land the sea will claim in the future, if it rises by 5, 12, and 25 feet. Nickolay Lamm, a 24-year-old researcher and artist saw the interactive maps and wondered: "What would this actually look like in real life?" Lamm told Mashable in an email interview that "the only imagery I had of sea level rise came from Hollywood." So he decided to put his skills to work..."
O.K. On a Cold Scale of 1 to 10, 1 being minor goosebumps, 10 is Minnesota's record cold of -60 F. (Tower, on Groundhog Day 1996) - the next 36 hours will be a 4. Really.
Some readers have shared their fondest memories of the REAL arctic fronts that swept into town on a regular basis in the 70s. "Using a credit card to scrape the ice from the INSIDE of my windshield." "Holding my breath, so I wouldn't feel the ice crystals up my nose!" "Suddenly owning a Flintstone Car with tires made of concrete!" Ah, those were the days.
Today will be plenty cold, in fact you can count the high on two fingers (3 if you're bad with math, like me) - a wind chill of -20 F. If skies clear and winds ease, tonight may be the coldest of winter; Friday morning wake-up air temperatures from -12 to -16 F.
This will be a relatively quick, concentrated burst of pain. Saturday looks tolerable (upper teens!) with 20s Sunday; a thaw likely by late next week. Snow? Can I interest you in a fresh foot of lake effect over the U.P. of Michigan?

Nighttime Tornadoes Are Worst Nightmare. Here's an overview of some new research from Northern Illinois University that shows that tornadoes that strike between midnight and dawn are 2.5 times more likely to result in fatalities, especially over the Mid South, from Arkansas into Tennessee and Kentucky. The problem is obvious: people are asleep, not monitoring media, apps or radio. How best to get the word out of an oncoming tornado at 2 am? NOAA Weather Radio. It may be the only thing that will set off a shrill alarm when there's a tornado warning for your county (if it has S.A.M.E. technology). Here's an excerpt of the article at Northern Illinois University: "A new study by Northern Illinois University scientists underscores the danger of nighttime tornadoes and suggests that warning systems that have led to overall declines in tornado death rates might not be adequate for overnight events, which occur most frequently in the nation’s mid-South region. Over the past century, the tornado death rate has declined, in large part because of sophisticated forecasting technology and warning systems. But the researchers found that the nighttime tornado death rate over the past century has not shared the same pace of decline as the rate for daytime tornadoes. “The proportion of nocturnal fatalities and killer tornado events has increased during the last half century,” said lead author Walker Ashley, an NIU meteorologist and professor of geography. “Unfortunately, this nocturnal fatality rate appears to be a major factor for the stalled decline in national tornado-fatality tallies during the past few decades....”
The Silver Lining In Drought: 5 Upsides To Rain-Free Weather. O.K. I'm a glass-half-full guy, but I'm not sure this one passes the smell test. Try explaining this to a farmer in Worthington or someone with lakeshore (in theory) on White Bear Lake, or towns in southwestern Minnesota where aquifers continue to recede, threatening agriculture and drinking water. But in the spirit of full disclosure here's an excerpt from a story at NPR: "Drought is mostly seen as a bad thing — and for good reason. It dries up crops, destroys landscaping and stops ships from moving. But even the lack of rain clouds has a bright side...Another upside of the drought? Fewer pests. And not just those plaguing grapes, but fewer bugs that, well, bug humans. Mike McClain at Metropolitan Mosquito Control District in the Twin Cities says the types of mosquitoes that drive people crazy tend to multiply after it rains. "And when you have real dry conditions that we did the last half of 2012, the actual number of complaints about mosquitoes and the number biting people tends to go way down," he says. "And that's a good thing. People are a little less irritated by mosquitoes during drought..."

Are Tornado Alleys A Myth? It's all how you look at the data, right? Here's an excerpt of a fascinating perspective from Discovery.com: "...As she wrote in her AMS meeting poster, Tornado Alley and Dixie Alley are concepts coined by members of the meteorological community, specifically, Tornado Alley by Fawbush & Miller in 1952, and then Dixie Alley by Dr. Allen Pearson in 1971. “But no universal definition of either concept exists; they shift, expand, and shrink with different publications, authors, and purposes. They are sociopolitical rather than scientific concepts,” Henderson explained (you can see her poster here). The thing about the original Tornado Alley, she said, is that once it was established, it became the scientific standard against which other alleys were defined. The concept of a tornado-prone “alley” is a natural outgrowth of 20th century meteorological history. Tornado alleys are terms that have become “scientized,” she told me. “Scientization transforms sociopolitical concepts, ideas, and other phenomena into metrics that can be standardized and measured...” (photo: meteorologist Aaron Shaffer at WeatherNation TV).
Study Links Headaches And Migraines To Weather. Lightning as a possible trigger for serious headaches? Here's a clip from wkms.org: "If you've ever blamed the weather for a splitting headache, you might be right. A new University of Cincinnati study finds that lightning may affect the onset of headache and migraines. "What we found was that on days with lightning around the patients' homes there was approximately a 30-percent increase in headache activity, or headache occurrence, and also a 30-percent increase in migraine," said fourth-year medical student Geoff Martin, one of the researchers. The study looked at chronic headache sufferers. There are a number of ways lightning might be a trigger..." (Lightning photo: AP)
Research Spawns Stunning Hurricane Sandy Animations. Here are a few clips worth watching, courtesy of meteorologist Andrew Freedman at Climate Central: "...In Sandy's wake, researchers have tried to gain a better understanding of the characteristics of this fascinating storm, and their work has already resulted in some interesting insights. Mel Shapiro, an atmospheric scientist who studies how tropical storms and hurricanes transition into powerful extratropical storm systems, recently produced a series of astonishing animated visualizations showing the inner workings of Sandy as the storm moved up the Eastern Seaboard and eventually made landfall on the evening of Oct. 29. These visualizations were produced with an ultra-high resolution computer model run at the National Center for Atmospheric Research in Boulder, Colo. Known as the ARW-WRF model, it used data from an operational computer model that the National Weather Service used to forecast the storm..."

The outflow jet can be seen in red colors moving away from the storm, toward the Midwest. Particle trajectories help show how the air was flowing throughout the storm. This was done by simulating the movement of particles inserted into a modeled storm environment." Credit: Science by Mel Shapiro and Thomas Galarneau.

Twice As Many Structures In FEMA's Redrawn Flood Zone. Many homeowners living near the ocean will be forced to raise their homes by several feet, or risk not being able to qualify for any insurance. The New York Times has the story; here's an excerpt: "New federal flood maps released on Monday revealed the grim news that many New Yorkers were girding for after Hurricane Sandy sloshed away: More areas farther inland are expected to flood. Tidal surges will be more ferocious. And 35,000 more homes and businesses will be located in flood zones, which will almost certainly nudge up insurance rates and determine how some structures are rebuilt. (Photo above: Gizmodo).
"Superfog" Not To Be Taken Lightly, Expert Says. Here's an excerpt of an interesting article at gainesville.com that caught my eye: "The monster that formed over Paynes Prairie on Jan. 29, 2012, and led to what is believed to be the deadliest set of accidents in Florida history wasn’t merely fog or smoke or a combination of the two. It was a unique phenomenon that can arise when the conditions are ripe, and it could kill again. Meteorologist Gary Achtemeier with the U.S. Forest Service knows it well. He had named it “superfog” and warns it is not to be taken lightly. “There is only one course of action for a motorist encountering superfog, and it is not to drive. I liken it to a bridge collapse,” Achtemeier said. “It has to be stressed that it is a unique phenomenon and is extremely dangerous...”

Research: Discovery Of Upper Atmosphere Bacteria That Affect Weather. Here's an excerpt from examiner.com: "...The finding is of interest to atmospheric scientists, because the microorganisms could play a role in forming ice that may impact weather and climate. Long-distance transport of the bacteria could also be of interest for disease transmission models. The microorganisms were found to be the appropriate size to facilitate the formation of water droplets and ice in the regions where they were discovered. When the air masses studied originated over the ocean, the sampling found mostly marine bacteria. Air masses that originated over land had mostly terrestrial bacteria. The researchers also saw strong evidence that the hurricanes had a significant impact on the distribution and dynamics of microorganism populations..."

In Energy Taxes, Tools To Help Tackle Climate Change. There's growing concern among farmers about crop insurance, how a spate of recent disasters (Sandy comes to mind) and the federal deficit may put even more pressure on farmers grappling with a persistent drought over the nation's midsection. Here's an except of a New York Times story that caught my eye: "...The erratic weather across the country in the last couple of years seems to be softening Americans’ skepticism about global warming. Most New Yorkers say they believe big storms like Sandy and Irene were the result of a warming climate. Whether climate change is directly responsible or not, the odd weather patterns have underscored the risk that it poses to all of us. What’s yet to be seen is whether this growing awareness of the risks will translate into sufficient political support to address climate change, especially after we figure out the costs we will have to bear to do so. In his inaugural address, President Obama wove Hurricane Sandy and last year’s drought into a stirring plea to address climate change. “The failure to do so would betray our children and future generations,” the president said..."

Climate Hawk: GOP Will "Pay In The Future" For Ignoring Climate Change. Yes, this is what I'm trying to explain to my friends on the right side of the political aisle. A few Republicans are paying attention; they seem to realize that this is a big deal, especially among younger voters. Here's an excerpt from Buzzfeed Politics: "U.S. Senator Sheldon Whitehouse, one of Congress' few outspoken environmental advocates, is making a new argument for legislative action on climate change: Lawmakers who oppose future measures to reverse global warming, Whitehouse argues, will pay a price — in votes. Whitehouse, who last Thursday announced the formation of a bicameral task force to address the issue, compared climate change to social issues like gay rights and immigration reform that Democrats claim are moving to the center. "I'm hoping we can convince Republicans that this is a big generational issue and, like being on the wrong side of immigration and gay rights, there will be a huge political price to pay in the future for being on the wrong side of climate change," said Whitehouse, the Democratic junior Senator from Rhode Island, in an interview with BuzzFeed..."

The problem is that this unfortunate phenomenon hurts the pocket books of some really great Americans, like Charles and David Koch. We are two filmmakers who want to tell the other side of the story. If we can get enough funds together, we'll be able to make a documentary that discredits the current theory of Global Warming so that Charles and David can quit worrying about the earth and get back to their favorite pastime, making money...."
Groundwater Depletion Linked To Climate Change. We assume that when we drill a well, we'll eventually find (drinkable) ground water. But aquifer depletion is a real concern, especially over southwestern Minnesota. Here's a clip from a must-read article at ScienceDaily:..."Over-pumping of groundwater for irrigation is mining dry the world's ancient Pleistocene-age, ice-sheet-fed aquifers and, ironically, at the same time increasing sea-level rise, which we haven't factored into current estimations of the rise," says Allen. "Groundwater pumping reduces the amount of stored water deep underground and redirects it to the more active hydrologic system at the land-surface. There, it evaporates into the atmosphere, and ultimately falls as precipitation into the ocean." Current research estimates oceans will rise by about a metre globally by the end of the century due to climate change. But that estimation doesn't factor in another half-a-centimetre-a-year rise, says this study, expected due to groundwater recycling back into the ocean globally..."

Whispers From The Ghosting Trees. This is a very long (and rather haunting) explanation of why so many trees are sick and dying worldwide. Elevated levels of ozone may be the problem. An excerpt of this worthy read courtesy of ScienceBlogs: "...Is it merely a colossal coincidence that all over the world, within the past few decades and at a hugely accelerating rate, trees are dying? If it’s not a coincidence, what is the underlying factor? Fair warning – this post will be a long explanation as to how there is an underlying factor, and why it is pollution. One of the strongest and most persuasive evidence for me has been the visible damage to foliage and needles that became virtually universal several years ago. Serious, terminal damage can occur in roots before any of the classic symptoms appear on leaves…so the fact that by the end of the summer growing season, it is just about impossible to find a single leaf on a tree, bush, garden produce or ornamental flowering plant that ISN’T visibly injured indicates the extent to which the problem has intensified. Just about any link to my blog will include photos of typical leaf damage...."
Colorado: Are January Red Flag Fire Warnings In The Mountains Part Of A New Climate Reality? Here's an excerpt from The Summit County Citizens Voice: "January fire warnings, nearly unprecedented 30 years ago, have become more common the last decade. Illustrating the persistence of extraordinary drought conditions in parts of Colorado, the National Weather Service issued a Red Flag fire warning for the Rocky Mountain foothills west of Denver north to the Wyoming border and encompassing areas that were scorched by last summer’s High Park Fire. Boulder-based National Weather Service forecaster Mike Baker said the agency decided to post the warning after three wildfires were reported Wednesday (Jan. 24) within the span of an hour. All three fires were above 8.500 feet elevation on the east slope of the mountains along the Front Range, Baker said..."
Skating Rinks Monitor Climate Change. A grass-roots, citizen's crowd-sourced effort to track the impact of a warming climate across Canada, by monitoring ice skating conditions. Here's more from discovery.com: "In the latest citizen science venture, backyard ice skaters are monitoring climate change in Canada and the northern United States. After Canadian scientists predicted that global warming will eventually be the demise of backyard skating rinks, a group of geographers at Wilfrid Laurier University in Waterloo created RinkWatch. In just 20 days, 630 volunteers signed up to keep tabs on the condition of their home rinks..."
Obama Talks Climate Change. California Is Acting On It. Here's a clip from a story at Time Magazine: "It’s not the happiest time to be an environmentalist. Climate change hit home last year with brutal force: 2012’s historic drought singed much of the Midwest, turning farms to dust and withering the corn crop. Other parts of the U.S. suffered through storms like Sandy and massive wildfires. Average annual temperatures in the continental U.S. beat the previous recorded high by a full 1°F (1.8°C). And the future is uglier still: over the weekend, the British economist Nicholas Stern warned that climate change could be even worse than he predicted in his sobering 2006 report on the financial impact of warming, while on Jan. 28 the National Oceanic and Atmospheric Administration (NOAA) released a draft report outlining the serious threat that sea-level rise poses to the coastal U.S..."
