Arthur's Revenge? Record Chill Monday into Tuesday - Summer Returns Late Week

Posted by: Paul Douglas Updated: July 12, 2014 - 11:38 PM

Arthur's Revenge?

Historically we are now entering the hottest week of the year. MSP average highs plateau at 84F between July 6-21. We SHOULD be in the 90s. I SHOULD be babbling about dew points, heat indices and hot weather safety tips.

Instead I'm checking the furnace, digging my favorite Twins sweatshirt out of cold storage and debating whether including Monday's forecast wind chill is a smart career move. Answer: probably not. A wind chill in July? That's a new one.

One theory that could have merit: Hurricane Arthur may have dislodged a chunk of unusually chilly air over James Bay as it howled into Canada's Maritimes last week. Much like powering up a snow blower in your attic throws debris into the family room, intense counterclockwise winds howling into eastern Canada disrupted an already fickle & unstable jet stream, now bulging southward with chilly implications.

We cool off today; tomorrow will feel like any other October 7; a wind chill in the 50s. I'm so sorry. Tuesday's MLB All-Star Game should be the chilliest on record. I wouldn't be surprised to see the Vikings or Gophers take the field.

Our weather has become a Meteorological Bizarro World.

What's next? I wish I knew.


500 mb Winds: Typical for Early October. Jet stream winds buckle, plunging record chill unusually far south into the Upper Midwest and Great Lakes. While the western USA and Canada fries with highs well up into the 90s, even some 100s. Yes, this is unusual for mid-July, historically the warmest period of the entire year. 84-hour NAM 500 mb winds and vorticity: NOAA and HAMweather.


A New Level of Weather Extremes. Temperature anomalies Monday evening may be 20-24F cooler than average from the Twin Cities to Des Moines and Madison, while readings 30-35F warmer than average bak much of western Canada, sparking a rash of records. I can't remember (ever) seeing these kinds of extremes in July, at least going back to the early 70s. Map: Weather Bell.


Tuesday Morning: Furnace-Worthy. Where are those sweatshirts I stashed into cold storage back in early May? Get ready for a fleeting time warp, Tuesday wake-up temperatures ranging from mid 40s to low 50s. I wouldn't be shocked to hear of a few frost reports near Embarrass and Tower by Wednesday morning. Map: Weather Bell.


This Too Shall Pass. Extended weather data from the ECMWF model shows showers Monday with a chill factor (again, my apologies) dipping into the low and mid 50s. We'll set a record Monday for the coldest July 14 daytime high, dating back to 1871. Game time temperatures will be in the low to mid 60s for Tuesday evening's MLB All-Star Game, probably the coolest All-Star baseball game ever played. Dew point drop into the 40s, typical for late September and early October, before summer returns by the end of the week. Meteogram: Weatherspark.


Sandbags on 'Tonka. Saturday evening I noticed a number of homes still have sandbags on their shoreline, something I've never (ever) seen before. The water level has come down a bit, maybe an inch or two, but at the rate we're going no-wake restrictions may not come off Lake Minnetonka until late July or even early August.


Four Weather Events in History Mistaken For The Apocalypse. One of them, according to this interesting story at AccuWeather.com, was 1816, the "Year Without a Summer". Here's an excerpt: "...As the weeks continued, the icy winter spell would linger for the remainder of the summer, causing an immense burden on farmers across the country. "On July 4, water froze in cisterns and snow fell again, with Independence Day celebrants moving inside churches where hearth fires warmed things a mite," Virginia resident Pharaoh Chesney is quoted by the Smithsonian Magazine. "Thomas Jefferson, having retired to Monticello after completing his second term as President, had such a poor corn crop that year that he applied for a $1,000 loan," the article reported..."


NASA's TRMM Satellite Maps Tropical Storm Neoguri's Soggy Path Through Japan. Satellite-derived rainfall estimates - pretty cool, and surprisingly accurate. Here's an excerpt from Science Codex: "...Southern Japan received a soaking from Tropical Storm Neoguri on July 9 and 10 and data from the TRMM satellite was used to create a map that shows how much rain fell in Kyushu. Kyushu is the southwestern most and third largest island of Japan. The island is mountainous and is home to Mount Aso. Heavy rainfall from Neoguri fell on land that was already soaked in the past week from a slow moving frontal system..."

Image credit above: "This rainfall analysis using TRMM satellite data showed that rainfall totals of over 490 mm (19.3 inches) fell in western Kyushi over the period from July 3-10, 2014.The red line indicates Tropical Storm Neoguri's track."

So What Do You Know About Hurricanes? Metro Jacksonville has a terrific infographic with a few surprises: "Considering it's hurricane season, Metro Jacksonville shares a Global Data Vault infographic featuring data provided by the Federal Emergency Management Agency (FEMA)."


NASA Spots a Super Typhoon. National Geographic has a post about "Neoguri", captured by the ISS, The International Space Station: "Watch out, Japan!" said European Space Agency astronaut Alexander Gerst after taking this July 7 picture of Supertyphoon Neoguri from the International Space Station. The supertyphoon lashed Okinawa this week, and at the time the photo was taken, was producing 150-mile-an-hour (240-kilometer-an-hour) winds..."

Upgraded HWRF and GFDL Hurricane Models Excelled During Hurricane Arthur. Weather Underground has a good summary of how NOAA's enhanced, recently upgraded high-resolution models just performed; here's an excerpt: "The landfall last week of Hurricane Arthur, the first named tropical system in the Atlantic for 2014, brought a quick start to this year’s hurricane season. Perhaps lost in the predictions and preparations for Arthur’s landfall was the fact that there have been major upgrades this year to the two operational National Weather Service (NWS) regional hurricane prediction systems, the GFDL and HWRF models. Here we will provide background on each of those models and highlight the forecast improvements achieved from recent upgrades to both models..."

Sea Surface Temperatures (SST) are denoted by the color shading, with the darker colors of blue showing the cooling of the SSTs due to the hurricane winds mixing the cooler waters from below to the surface."


Study Provides New Approach to Forecast Hurricane Intensity. Predicting hurricane intensity is much more challenging than forecasting track; here's an excerpt of a story focused on new research from The University of Miami: "New research from University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science suggests that physical conditions at the air-sea interface, where the ocean and atmosphere meet, is a key component to improve forecast models. The study offers a new method to aid in storm intensity prediction of hurricanes. “The general assumption has been that the large density difference between the ocean and atmosphere makes that interface too stable to effect storm intensity,” said Brian Haus, UM Rosenstiel School professor of ocean sciences and co-author of the study. “In this study we show that a type of instability may help explain rapid intensification of some tropical storms...”


Data and Analytics Try To Limit Hurricane Damage. Dell Computer has an interesting guest post about the power of analytics and models to get a better handle on which communities in Hurricane Alley are most vulnerable, and how much cash to set aside for a rainy (windy) day. Here's a clip: "...With every new hurricane that makes landfall in the U.S., advanced catastrophe modeling and analytics allow property-casualty carriers to more accurately price a homeowners insurance policy. Models also help insurance carriers calculate the amount of capital they need to set aside in reserve to pay claims and how many catastrophe insurance policies insurers can afford to reinsure. Catastrophe models help insurance companies plan ahead and serve as a tool that contributes to the industry allocating capital more efficiently, Larsen says..." (File image: EPA).


Graphic: Wildfires Raging in North America. Canada's National Post has a terrific infographic and explainer, pinpointing all the wildfires across North America. Smoke from the 100+ blazes burning in Canada's Northwest Territories has been sweeping southward into the USA in recent weeks. Here's a clip: "Hundreds of wildfires are raging in British Columbia, Alberta, Quebec and the Northwest Territories while the U.S. is battling large blazes in Arizona, Nevada, Utah, Idaho, California, Colorado, Florida, Washington state and New Mexico. Canada has already had more than 2,000 wildfires this year. And this week saw U.S. President Barack Obama ask Congress for $615-million to help fight the fires this season. So where are the hotspots in North America and how do those fires start and spread?"


What Is Causing The Kidney Stone Epidemic? Staying hydrated in the (increasing) heat is everything; here's an excerpt from io9.com: "Pediatric urologist Gregory Tasian and his team analyzed over 60,000 medical records of people with kidney stones in major cities throughout the U.S. What they found was that people were more likely to develop the painful calcium deposits (pictured above) in their kidneys when average temperatures rose over 50 degrees. In fact, many cases of kidney stones cropped up roughly three days after a hot day. Now that climate change means that some regions of the globe are heating up, it's likely that kidney stones will become even more common..."


Car Insurance Companies Want to Track Your Every Move - And You're Going to Let Them. If you want the lowest possible rate you give up a little more of your privacy (and soul) right? Here's the intro to a story at Quartz: "The proposition is simple: Install a device in your car and allow your insurance company to monitor your driving—how fast you drive, how hard you brake, how sharply you corner, and so on. In exchange, it will give you a discount on your premiums.  That might sound alarming, but it shouldn’t be surprising. Considering internet users already happily trade data on every online move they make in exchange for free services, the only surprise is tracking-based insurance isn’t already more widespread..."


Say It Isn't So - World's Largest Mall Slated for Dubai. It should be noted that Dubai already has 52 malls, each with it's own magazine. Because they do BIG THINGS in Dubai. Maybe our Mall of America can expand into MSP International to keep us in the hunt. Gizmag has more details: "...Dubai Holding hasn't revealed firm dates nor a budget for the project yet, but we do know some basic information. It comprises 743,224 sq m (8 million sq ft) of floorspace, which makes it easily the largest mall in the world, a shade larger than China's Forbidden City, and about four times the size of France's Louvre Palace..."


Every State in the USA, Ranked by it's Food/Drink. Minnesota ranked 23rd out of 50 states. Really? Here's an excerpt of a sure-to-be-controversial story at Thrillist: "...Surly’s was at the forefront of a damn fine brewing scene, but really this ranking is about the glorious innovation that is the Juicy Lucy. Any chump can melt cheese ON a burger, but it takes vision to put it INSIDE the burger. For such achievements you get a pass on that suspect-looking hot dish stuff..."


Amazon Asks FAA For Permission to Fly Drones. Some-day delivery within 30 minutes? Like a vending machine in the sky. The Associated Press has the story; here's a clip: "...In a letter to the FAA dated Wednesday, Amazon said it is developing aerial vehicles as part of Amazon Prime Air. The aircraft can travel over 50 miles per hour and carry loads of up to 5 pounds. About 86 percent of Amazon's deliveries are 5 pounds or less, the company said. "We believe customers will love it, and we are committed to making Prime Air available to customers worldwide as soon as we are permitted to do so," Amazon said in the letter..."

Climate Stories....

Adapting to Climate Change: Let Us Consider the Ways. Breaking news: we're already being forced to adapt to a warmer, more volatile climate. ScienceNews has the Op-Ed; here's an excerpt: "...The title of the report, “Climate Change Adaptation,” sounded familiar. That’s because it was very similar to the working title of this issue’s cover story. And although our article deals with the feathered and flowered worlds of plants, animals and other creatures — and not military infrastructure — biologists are similarly concerned with how natural populations might respond to the consequences of climate change. The feature “Quick change artists” tells an important story about some of the ways that vulnerable organisms might adapt to a changing world..." (Image: Shutterstock).


North Carolina's Outer Banks "Ban" Rising Seas. Many people in Europe think we've lost our minds on this side of the pond, at least when it comes to science. Here's a clip from a story at a radio station in the U.K. that caught my eye: "...An overwhelming majority of scientists predict sea levels will rise by at least a metre up and down the coast of the US by 2100.   One of them is Professor Orrin Pilkey, Professor Emeritus of Earth and Ocean Sciences, at Duke University in North Carolina. He says the people of the Outer Banks and their politicians are living in denial. It is impossible, he says, for politicians simply to legislate that a scientific prediction should be ignored. "All up and down the East Coast, Gulf Coast and West Coast it's all the same and still they stick their heads in the sands," he says..."


No Magic Bullet for Climate Change, Swiss Scientist Says. No silver bullet, but plenty of silver buckshot. The Boston Globe has the article; here's an excerpt: "...The lesson, says Lino Guzzella, president-elect of the renowned Swiss university known as ETH Zurich, is we cannot expect technological discoveries like those conceived by Einstein to save us from the pain of climate change. “We cannot sit and fold our hands waiting for a new technology. If we have to wait until the next Einstein comes, it won’t do,” says Guzzella. “The problems we are talking about need to be tackled with the existing tools we have...”


"But There's Been No Warming Since 1998!" Global surface temperatures have plateaued, but the oceans continue to warm, in fact more than 90% of all warming is going into the world's oceans. Here's an excerpt from The Union of Concerned Scientists: "...Focusing on relatively short time periods to claim global warming is not happening is a misleading way to use statistics. These false claims have become so persistent that late last year the Associated Press asked a team of independent statisticians to review global temperature data without revealing to them what the data represented.[5] All of the statisticians concluded that the data showed an unmistakable upward trend over time..."


In Las Vegas Climate Change Deniers Regroup, Vow to Keep Doubt Alive. Bloomberg Businessweek has the story; here's the introduction: "Earlier this week, the Heartland Institute convened its Ninth International Climate Change Conference in Las Vegas. A nonprofit, free-market think tank in Chicago with a $6 million annual budget, Heartland has been hosting conferences since 2008 for those dubious of the science confirming human-caused climate change. It is called the ICCC for short, the acronym an intentional echo of the IPCC, the Intergovernmental Panel on Climate Change, an international body that has published the most comprehensive studies of global warming..."

Cool Canopy of Crud Today - Timing Holiday Weekend T-storms - El Nino: Is 2014 The New 1997?

Posted by: Paul Douglas Updated: May 21, 2014 - 9:07 AM


Imagine if the Twins, Vikings, Timberwolves and Wild lost EVERY game, and you were the poor schlub-of-a-sportscaster who has to report on what happened & why. Over time this perpetual losing streak would begin to eat away at your soul.

As meteorologists we're trained to take an objective look at the data; take emotion out of the equation. Just issue the best forecast you can. That looks good on paper, but when the weather is foul for extended periods of time - and nearly everyone you talk to is ranting about "this crummy pattern!" - it wears on you.

A foul forecast fatigue sets in.

So I'm as happy as the next guy to see Mother Nature turning the page. May is finally popping up on the maps and 80F should feel like a revelation by the weekend.

Lingering fog and low-level crud kept us a bit cooler than predicted yesterday, but a puff of drier, slightly cooler Canadian air treats us to sunshine the rest of the week. No frost this time around.

A return southerly flow of humid air sparks T-storms Sunday and Memorial Day. If the sun peeks out for even an hour or two (likely) we'll see highs at or just above 80F. In fact we may see 80s much of next week with sporadic outbreaks of T-storms, some capable of minor flash flooding as a warm front stalls nearby.

In the blog below: lousy weather is good for job productivity and globally, April tied 2010 for the warmest on record.


Canopy of Crud. Cool exhaust on the backside of last night's frontal passage, coupled with chilly air aloft and lingering moisture will keep us mostly cloudy today; highs in the 50s north to low and mid 60s south, with a stiff northwest breeze at 10-20 mph. Not a picture-postcard-perfect day on the lake by any stretch.


Gradual Warming Trend. Memorial Day weekend doesn't look quite as warm as it did yesterday, but I still see upper 70s to near 80F from Saturday into Memorial Day. T-storms may keep us a bit cooler, especially Sunday, which appears to be the wettest day right now with the most widespread T-storm outbreak. ECMWF data suggests a streak of 80s next week. You remember 80s, right?


84 Hour Future Radar. HAMweather visualization of NOAA's NAM data shows showers and T-storms, some severe, popping up across the Ohio Valley today, pushing into the Mid Atlantic. A plume of moisture pushing out of the Gulf of Mexico may drop significant rains on drought-plagued regions of Texas and Oklahoma; T-storms reaching the Upper Midwest again by late Saturday and Sunday.


Slight Risk. NOAA SPC shows a slight threat of severe storms today from Denver east to St. Louis, Louisville, Columbus and Washington D.C. - storms firing along an active frontal boundary by mid and late afternoon.


April 2014 Ties 2010 For Warmest On Record, Worldwide. And the first 4 months of 2014 were the 6th warmest on record. A strong El Nino forecast for the latter half of 2014 may cause global temperatures to spike even more. Here are more details from NOAA NCDC:

  • The combined average temperature over global land and ocean surfaces for April 2014 tied with 2010 as the highest on record for the month, at 0.77°C (1.39°F) above the 20th century average of 13.7°C (56.7°F).
  • The global land surface temperature was 1.35°C (2.43°F) above the 20th century average of 8.1°C (46.5°F), marking the third warmest April on record. For the ocean, the April global sea surface temperature was 0.55°C (0.99°F) above the 20th century average of 16.0°C (60.9°F), also the third highest for April on record.
  • The combined global land and ocean average surface temperature for the January–April period (year-to-date) was 0.64°C (1.15°F) above the 20th century average of 12.6°C (54.8°F), the sixth warmest such period on record.

Are We Overdue For A Major Hurricane? The short answer is yes. It's been 9 years since a Category 3 or stronger hurricane hit the U.S. coastline (Wilma in 2005). Among other fears: complacency. It's been so quiet, maybe we let our guard down a little. In today's Climate Matters, new features and capabilities from NHC in 2014, who remind us all that "it only takes one storm": "WeatherNationTV Chief Meteorologist Paul Douglas goes over the unusually quiet past few years for hurricanes in the Atlantic. Statistically we are vastly overdue for another major hurricane. Why has the Atlantic been so quiet?"


New Hurricane Tools and Capabilities in 2014. NHC will be issuing operational storm surge forecasts if and when a tropical system approaches the coast, but I found a few other interesting nuggets here.


Sample NOAA NHC Storm Surge Forecast. No, residents of Tampa don't need to be concerned, at least not yet. Keep in mind most of the structural damage from hurricanes doesn't come from high winds, but from the "storm surge", a rapid rise in water levels triggered by sustained winds and low pressure, pushing water well inland. This year NHC will begin issuing surge predictions based on a storm's track, intensity, natural tides and bathymetric data (slope of terrain just offshore).


How Might El Nino Affect Hurricane Season? In clip #2 of Climate Matters: statistically El Nino summers and falls tend to increase wind shear over the tropics, resulting in fewer tropical storms and hurricanes. But that's no reason for complacency - we've had a nearly 9 year lull in hurricane activity in the Atlantic and Caribbean, but at some point America's luck will run out. Will 2014 be the year? "The last major hurricane to hit the United States was Wilma in 2005. Since then the tropics have been *relatively* quiet, and that is leading some meteorologists to worry. WeatherNationTV Chief Meteorologist Paul Douglas goes over just why we shouldn't let our guard down."


Massive Wildfires Cause For Concern In Oklahoma. Here's an excerpt from The Daily Ardmoreite in Ardmore, Oklahoma: "Wildfires in Oklahoma so far this month have burned more than 60 times the average acreage, according to data from the Oklahoma Forestry Services. Since 2005, the state has averaged 454 acres burned from May wildfires. So far this month, more than 30,000 acres have burned, The Oklahoman reported Sunday. Guthrie Fire Chief Eric Harlow says that if things don't change, fire crews will be in for a long summer. "We shouldn't have this fire behavior the first week of May," he said...."

File Photo credit above: "Firefighters work to extinguish a flare up on Monday, May 5, 2014, in Guthrie, Okla. Gov. Mary Fallin has declared a state emergency across Oklahoma after several wildfires broke out across the state, including a blaze north of Oklahoma City that destroyed at least a half dozen homes and left one man dead." (AP Photo/Nick Oxford).


Forest Services Expands Fire-Fighting Tanker Fleet. Under the extenuating conditions (historic drought from California to Texas and Oklahoma) this strikes me as a prudent move. Here's an excerpt from AP and ABC News: "As the Obama administration pushes Congress to ensure that enough money is available to fight destructive wildfires, the U.S. Forest Service announced Tuesday it was adding four aircraft to its firefighting fleet ahead of what's expected to be another hot, dry summer in the West. In a statement, the service said it will have a second DC10 and three smaller planes in service in the coming weeks to support over 10,000 firefighters "in the face of what is shaping up to be a catastrophic fire season in the southwest..."


Monitoring The State of Global Rainfall and Drought. redOrbit has an interesting story about pushing the science to be able to accurately predict drought, months in advance. Here's an excerpt: "...A team of researchers from UC Santa Barbara and the United States Geological Survey (USGS) has developed a new dataset that can be used for environmental and drought earl warning. The dataset is called CHIRPS, or Climate Hazards Group Infrared Precipitation with Stations, and it is the result of a collaboration between UCSB's Climate Hazards Group and USGS's Earth Resources Observations and Science (EROS).

El Nino: Is 2014 The New 1997? NASA Science has an update on what may turn into a significant warming of equatorial Pacific Ocean water; here's a video and story excerpt: "Every ten days, the NASA/French Space Agency Jason-2 satellite maps all the world's oceans, monitoring changes in sea surface height, a measure of heat in the upper layers of the water.   Because our planet is more than 70% ocean, this information is crucial to global forecasts of weather and climate. Lately, Jason-2 has seen something brewing in the Pacific—and it looks a lot like 1997. "A pattern of sea surface heights and temperatures has formed that reminds me of the way the Pacific looked in the spring of 1997," says Bill Patzert, a climatologist at NASA's Jet Propulsion Laboratory. "That turned out to be the precursor of a big El Niño..."

Strongest El Nino in 17 Years Brewing: Oregon Weather Watch. OregonLive.com has more data from NASA on a pending El Nino event, which may be the most significant since 1997-98. Here's an excerpt: "NASA satellites and ocean sensors are showing that sea surface temperatures in the equatorial Pacific Ocean this May look similar to the conditions in May 1997 that resulted in one of the strongest El Niño events of the last century during the fall and winter of 1997-98..."


How El Nino Might Alter The Political Climate. Here's a snippet from The Upshot at The New York Times: "...But El Niño has the potential to do more than offer a one-time jolt to climate activists. It could unleash a new wave of warming that could shape the debate for a decade, or longer. In this chain of events, a strong El Niño causes a shift in a longer cycle known as the Pacific Decadal Oscillation, which favors more frequent and intense El Niños during its “warm” or “positive” phase. The oscillation has been “negative” or “cool” since the historic El Niño of 1998..."


This Is What's Actually Making Your Horribly Unproductive.

I am allowed to enter the 9/11 Museum a few days before this week’s grand opening for the general public, but why would I want that? Why would I accept an invitation to a roughly $350 million, 110,000-square-foot refutation of everything we tried to practice, a gleaming monument to What Happened, not What Happened to Us?

New "Dual Carbon" Battery Charges 20 Times Faster Than Li-ion. Will new innovations and technological breakthroughs continue to make renewable power cheaper and accelerate adoption? Right now I wouldn't bet against the trends, as Moore's Law applies to solar, wind and other (clean) forms of energy. An even bigger question is whether most of these breakthroughs will originate in the USA or elsewhere? Here's a clip from an article at Gizmag: "Japanese company Power Japan Plus has announced the development and planned mass-production of "Ryden," a disruptive carbon battery that can be charged 20 times faster than an ordinary lithium-ion cell.

Huffington Post has a story that was not sponsored by America's hot tub manufacturers. Here's an excerpt: "...While hot tub rash typically clears up on its own without treatment, another more serious condition to be aware of is the potentially fatal Legionnaires’ disease, a type of pneumonia caused by a germ called Legionella, which is found in water (especially warm water) and can be breathed in from the steam or mist surrounding a contaminated hot tub -- people older than age 50, smokers and those with weakened immune systems are particularly susceptible..."


Netflix's Vision For 2025: 48 Million Channels. And still nothing worthwhile to watch? We'll see. Wired.com has the story and interview; here's an excerpt: "...According to Hunt, this will change with internet TV. He said Netflix is now working to perfect its personalization technology to the point where users will no longer have to choose what they want to watch from a grid of shows and movies. Instead, the recommendation engine will be so finely tuned that it will show users “one or two suggestions that perfectly fit what they want to watch now.” “I think this vision is possible,” Hunt said. “We’ve come a long way towards it, and we have a ways to go still.”


Sorry, But There's No Such Thing As A "Healthy" Sugar. But wait, I read just the opposite on the Internet. Sugar is GOOD for me, in large doses, preferably in processed food and Halloween candy. This article at Huffington Post will most certainly add to the confusion; here's the introduction: "We hate to be the bearers of bad news, but we feel the need to clarify a common misconception: There's no such thing as a "healthy" sugar. Or even a "less bad" sugar. Your body doesn't care if it's "organic" or "unrefined" or "all-natural," and it certainly doesn't care if Gwyneth Paltrow deems it suitable for her children's consumption. Done hyperventilating? Now let's delve into the nutritional science behind this..."

Climate Stories...

* thanks to science writer Greg Laden for passing this one along. I'm no rocket scientist, but even I can solve this one, Pat.

Weathercasters Grapple With Climate Change. No kidding. You have 3 minutes to discuss the (increasingly toxic) weather, and, oh, by the way, can you squeeze a little climate science in? Mission impossible, at least the way a typical local TV newscast is structured today. Here's an excerpt from a story at TVNewsCheck: "...But whether the administration reached out to the right people to cover the highly charged issue depends on whom you ask.  Even the weathercasters who went to the White House are not sure covering climate change should be part of their jobs. “I wish climatologists were doing this and not me. They know their stuff,” says Bill Martin, chief meteorologist at KTVU, the Cox-owned Fox affiliate in San Francisco (DMA 6). “I am not super comfortable talking about climate change. I am super comfortable talking weather,” says Martin, who was caught so off-guard by the administration’s invite that he didn’t even bother returning the initial calls, figuring they were pranks..."


Climate Change, Forest Fires Drove Widespread Surface Melting of Greenland Ice Sheet. Other factors come into play, beyond warming temperatures, according to this post at phys.org; here's a clip: "Rising temperatures and ash from Northen Hemisphere forest fires combined to cause large-scale surface melting of the Greenland ice sheet in 1889 and 2012, contradicting conventional thinking that the melt events were driven by warming along, a Dartmouth College-led study finds. The findings suggest that continued climate change will result in nearly annual widespread melting of the ice sheet's surface by the year 2100, and that a positive feedback mechanism may be set in motion..."

ESA's CryoSat Data: Antarctica's Ice Sheet Shrinking Faster Than Ever. Here's an excerpt from a good explainer at gizmag.com: "...The UK-based Centre for Polar Observation and Modelling analyzed data collected over three years (by nearly continuous surveillance) from CryoSat, to create the world's first comprehensive assessment of elevation change in the Antarctic ice sheets. Results of the analysis found that ice loss in the polar region was 31 percent greater than that of the previous period of observation (from 2005-2011), with substantial thinning of the ice in the Amundsen Sea area of West Antarctica..."

Evangelicals in Florida Turn To Climate Change And Call on Gov. Scott To Act. Full disclosure: I'm on the board of EEN, the Evangelical Environmental Network. It's President, Rev. Mitch Hescox, was recently quoted in the Tampa Bay Times; here's an excerpt of what he had to say: "...Among the panelists is the Rev. Mich Hescox, president of the Evangelical Environmental Network, who wrote a letter to Rubio about his widely publicized comments doubting man’s contribution to climate change. Hescox is also gathering signatures for a petition aimed at Scott. “As Christians, we believe that God's grace empowers us to honestly confront the challenges we face and change for the better,” it reads. “We are failing to keep our air and water clean for our children, contributing to a changing climate that most hurts the world's poor, and putting Floridians at risk as temperatures and sea levels continue to rise. To meet these challenges, we need leaders who understand our duty to God’s creation and future generations..."


National Landmarks Threatened By Climate Change. USA TODAY has the article; here's an excerpt: "...The report, which was not a peer-reviewed study, includes 30 at-risk locations, including places where the "first Americans" lived, the Spaniards ruled, English colonists landed, slavery rose and fell, and gold prospectors struck it rich. Locations include the Statue of Liberty; Jamestown, Va.; the Cape Hatteras (N.C.) Lighthouse; and the Kennedy Space Center. "You can almost trace the history of the United States through these sites," says Adam Markham, director of climate impacts at UCS and report co-author..."

European Space Agency's CryoSat-2 Satellite: Antarctica Shedding 160 Billion Tons of Ice A Year. Here's a clip from Daily Kos that I wasn't aware of: "...Antarctica is shedding 160 billion tonnes a year of ice into the ocean, twice the amount of a few years ago, according to new satellite observations. The ice loss is adding to the rising sea levels driven by climate change and even east Antarctica is now losing ice. The new revelations follows the announcement last week that the collapse of the western Antarctica ice sheet has already begun and is unstoppable, although it may take many centuries to complete..."


The Melting Isn't Glacial. Are we at a tipping point - or is the news coming out of West Antarctica and Greenland more "alarmist hype"? Are you willing to roll the dice? Here's a clip from a story at The New York Times: "...The ice sheets of Antarctica and Greenland together possess about 100 times as much ice as all of the mountain glaciers combined, but contribute only slightly more to the sea level rise: 310 billion tons a year, Dr. Scambos said. That is because most of the mountain glaciers lie in areas where temperatures are closer to the melting point than they are in Greenland or Antarctica, and so slight warming tips them to melting. Greenland, with 10 percent of the world’s ice, has enough to raise sea level by 23 feet. “I still think Greenland is the most important thing to watch for this century,” Dr. Scambos said..."

Climate Change: Get Ready or Get Sued. What are the liability implications of climate change, specifically the trend toward heavier summer downpours and more extreme flooding east of the Mississippi? The insurance industry and lawyers far and wide will be keeping a close eye on this case in Chicago's suburbs. Here's an excerpt of a story at The Washington Post: "...This is a new kind of storm associated with climate change,” Tom LaPorte, spokesman for the Chicago Department of Water Management, told Medill Reports on day two of the April flood. Extreme flooding is part of a pattern that has emerged in the last two decades, according to Illinois State climatologist Jim Angel. Now a major insurance company is suing Chicago-area municipal governments saying they knew of the risks posed by climate change and should have been better prepared. The class-action lawsuits raise the question of who is liable for the costs of global warming..."

The People of Miami Know About Climate Change. We're Living It. You no longer need a hurricane or even a coastal storm or thunderstorm downpours to get flooding in Miami. Now it often floods at high tide, a rising tide at that. Here's an excerpt from a story at The Guardian: "...People in Miami Beach are living climate change," said David Nolan, a meteorology and physical oceanography professor at the University of Miami. "They're on the frontline." The people of Miami Beach didn't need the National Climate Assessment to tell them low-lying south Florida is "exceptionally vulnerable to sea level rise". The city is already spending $206m to overhaul its drainage system. The day after the White House released its climate change report, Miami-Dade County's commission passed a 6 May resolution that calls on planners to account for sea level rise. Local officials across the four counties of south Florida are making similar moves. Almost anyone who lives in south Florida has a nagging fear about climate change. It's both abstract and, at times, very real..."

Global Warming Responsible for Increased Wildfires in California? If this is, in fact, a "natural cycle" it's one heck of a coincidence. Here's an excerpt from a story at Headline & Global News: "...Global warming also contributes largely to mega-fires, which occur when multiple wildfires combine together to form a larger, deadlier blaze, and the size of these fires makes it difficult for containment.  In the last decade, the occurrence of such fires has increased in frequency. According to Global Change, about 6.4 million acres have been burned per year on an average since 2010, amounting to a 3.5 million acres increase since the 1980s. Many studies have also highlighted that global warming also increases wildfires indirectly. This climate change leads to other factors that promote wildfires, such as drought and insect outbreaks..."

Upcoming +50F Temp Swing Since AM Tuesday!

Posted by: Paul Douglas Updated: January 9, 2014 - 7:06 PM

Minnesota Heat Wave

By Todd Nelson

As we climb out of the depths of this latest Arctic blast, I am reminded by a scene in one of my favorite movies filmed in Minnesota; Grumpy Old Men. As the late and great Walter Matthau steps outside to get the mail, he starts singing "Heat Wave", which was performed by the one and only Marilyn Monroe. If you do enough searching, you can find a pretty good rendition by Miss Piggy too.

If you're keeping track, the official low at the MSP Airport on Tuesday morning was -23F. The high today could be near the freezing mark (+32F). That's nearly a 50F temperature swing in nearly 4 days!

Ahh yes, freezing is going to feel amazing today... enjoy it!

I had a chance to talk to a good friend of mine yesterday, who now lives in Bullhead City, AZ and is a transplant from Duluth, MN. He mentioned that their overnight low was expected to dip into the 30s, which he now considers 'cold'. Snowbirds.

A quick moving system slides up from Kansas City, MO today with snow chances. It looks like nothing more than a light nuisance. Several weak clippers glide through the region into next week. Each one will spit at us and kick up some cool winds as they clip by. Hey, it's winter!

_____________________________________________________________________

THURSDAY NIGHT: More clouds. Not sub-zero! Low: 13. Winds: SE 10

FRIDAY: More clouds, light snow develops in far SE MN. High: 32. Winds: S 10

FRIDAY NIGHT: Light/nuisance snow continues. Low: 20

SATURDAY: Dripping icicles. Much better. High: 30

SUNDAY: Clouds thicken, light wintry mix possible. Wake-up: 16. High: 35.

MONDAY: Another clipper. breezy and cooler. Wake-up: 14. High: 22.

TUESDAY: More clouds, light snow possible. Wake-up: 18. High: 24.

WEDNESDAY: Partly sunny. Breezy again. Wake-up: 8. High: 23.

THURSDAY: Light snow, turning colder. Wake-up: 13. High: 18

This Day in Weather History

January 10th

1990: January heat wave. Twin Cities warms to 49 degrees.

1975: "Blizzard of the Century" begins also called the "Superbowl Blizzard" One of the worst Blizzards ever. Stranded people watched the Vikings lose the Superbowl on the 12th. The pressure hit a low of 28.62. This was the record until 1998.

___________________________________________________________________

Minnesota Heat Wave

Wow, it sure is nice to see 30s on forecast maps again isn't it? Looking out into next week, low temps don't appear to be too Arcitc. Stay tuned for more...

Winter Weather Advisory

The National Weather Service has issued a Winter Weather Advisory for the extreme southeastern MN and for most of central Wisconsin until 6am Saturday.

Snow Potential

There appears to be a fairly narrow swath of some shovelable snow across parts of extreme SE Minnesota and central Wisconsin through AM Saturday.

Feet of Lake Effect Snow?

Unreal! This is a picture from Rodman, NY where the snow tally from the latest lake effect snow event came in at 60"!!

Watertown, NY even got walloped with nearly 2ft.!

Impressive Snowfall Tallies

Thanks to the National Weather Service for the map below, which shows the snow accumulations over a 72 hour period from earlier this week. The numbers below suggests the highest tallies I could find from within the general area.

Snowfall Tallies

Lake Effect Snow From Space

A NOAA satellite captured the latest event from space. You can actually see the intense lake effect snow bands across the entire lake. Typically, the longer the fetch or stretch across the lake, the more intense the lake effect snow band(s) can be. There were even reports of thundersnow with this latest event!

Average Annual Snowfall

Here are some of the highest average annual snowfall tallies that I could find. According to NWS climate data, Marquette sees more than 200" of snow per year, while Watertown, NY sees nearly 80".

Average Annual Snowfall Tallies

The numbers above are based on individual sites over a 30 year period ending in 2010. The map below from the National Weather Service actually shows that some areas in the Eastern Great Lakes Region see nearly 300"!

An Icy Chicago River

If you look close enough, you can actually see ice chunks on the Chicago River from the picture below. Interestingly, Chicago is going from sub-zero weather to rain by Friday! Chicago, officially spent 37 hours below 0F earlier this week too!

Two Harbors, MN

Nice shot here from the Split Rock Lighthouse Facebook page, where temperatures earlier this week were dangerously cold. Lake Superior was a constant fountain of steam over the past few days, which can be seen a little bit in the picture below.

Major Burns in the Cold Weather

With the recent blast of Arctic air, many tried to 'enjoy' the cold by trying different cold weather experiments. One of the more popular ones was throwing boiling water into the air, but it caused some issues as several folks got some major burns.

"Over Monday and Tuesday, the Los Angeles Times counted at least 50 people on social media who reported burning themselves or their friends after trying to turn boiling water into snow. There were also several reports of people going to the hospital to receive treatment for burns."

Warming Trend Continues...

From AM Tuesday temps to high temperatures on Friday, some across parts of the nation could see a 50F+ temperature swing.

High Temps Friday

Highs From Normal Friday

Sunday Highs

Sunday Highs From Normal

Northern Lights Potential

Earlier this week, a solar storm erupted and sent an X1-Flare towards Earth, meaning northern lights may be visible for some in the higher latitudes.

Northern Lights Forecast

According to the Geophysical Institute at the University of Alaska Fairbanks, the northern lights forecast still remains HIGH into Friday.

Aurora OVATION

Here's a cool test product from NOAA, which shows the potential viewing area.

Idaho Snow Dog

Thanks to Duane Goudge for this picture out of Idaho Falls. Enjoy!

U.S. Snow Depth

According to NOAA, the U.S. snow cover as of Thursday, January 9th showed that nearly 50% of the nation was covered in snow.

More Snow on the Way

Here's a look at the snow potential over the next few days. Note the heavy snow potential across the western mountains, while a heavier band of snow can't be ruled out over parts of central Wisconsin.

Wetter & Warmer Into the Weekend

Several rounds of heavy precipitation will whip the Pacific Northwest over the coming days. Heavy rain and snow will be possible through early next week. One of these pieces of energy will slide through the middle part of the country on Friday with heavy rain, some icing and snow. By Saturday, that system will kick out a strong to severe thunderstorm threat in the Southeastern part of the country.

Tracking the Low

After Friday's system blows through the middle part of the country, the storm will move into Canada on Saturday. After that, we'll see a pretty constant flow from the Pacific with clipper systems and several chances of precipitation across the international border, the first of which can be see in southern Canada thru AM Sunday.

Precipitation Next 3 Days

According to NOAA HPC 3 day precipitation forecast, there appears to be widespread heavy moisture in the Pacific Northwest. There will also be decent amounts of moisture across the middle and eastern part of the country through the end of the weekend as a cold front sweeps across the country.

Saturday Severe Threat

As the said storm cross through the eastern part of the country on Saturday, strong to severe thunderstorms can't be ruled out. The Storm Prediction Center has already issued a SLIGHT RISK of severe weather from areas across eastern North Carolina to extreme northeastern Florida.

First Thaw In Over 2 Weeks (big temperature swings; weekend snowstorm for Chicago)

Posted by: Paul Douglas Updated: December 17, 2013 - 11:02 PM

Happy Drips

For the first time in over 2 weeks the mercury will rise above freezing today. Prepare to be serenaded by the soothing sounds of dripping icicles and gurgling drain-spouts. Happy noises.

NOAA reports the first half of December saw the 4th coldest daytime highs and 21st coldest nighttime lows in the Twin Cities since 1873. Nothing like easing into winter.

A puff of Pacific air treats us to mid-30s today. More waves of Canadian air slosh south, chilling us back down through the weekend - but not as Nanook as the first week of December.

As long as steering winds are howling from the west-northwest Minnesota's weather will be dominated by a family of Alberta Clippers; each one preceded by a brief warm-up, followed by cold winds and flurries. These fickle low pressure swirls moving in from Edmonton move quickly; starved for moisture, unable to tap a deep, rich layer of water vapor in the Gulf of Mexico.

One such storm may dump significant snow this weekend from Kansas City to Chicago. On the warm side of the storm highs surge into the 70s on the east coast - 60s into Washington D.C. and Philadelphia. Talk about weather-whiplash!

The January Thaw may come early this year.


More Whiplash - Outrageous Swings In Temperature Into Christmas. A storm pushing into California will drop significant snow across the Midwest and Great Lakes this weekend, complicating travel and shopping plans. Out ahead of the storm thoughts may turn (prematurely) to spring, with 60s as far north as Washington D.C. and Baltimore by Sunday. In today's edition of Climate Matters we take a look at unusually big swings in temperature looking out the next week: "WeathernationTV Chief Meteorologist Paul Douglas looks at another case of "weather whiplash" going from slush to almost 70°F in some areas. Just how warm can we expect it to be as we do some last minute holiday shopping?"


Fleeting Thaw, Then Colder. Temperatures rise into the 30s today, before the next clipper (preceded by a streak of light snow during the PM hours Thursday) drops temperatures into single digits by Friday morning. 84-hour 2 meter NAM temperature forecast courtesy of NOAA and Ham Weather.


Big Swings. It'll be nice to be "above average" today. Only in Minnesota do the locals sigh with contentment when temperatures surge into the 30s. After cooling down over the weekend another upward blip is forecast by ECMWF model guidance for Christmas Eve, then turning sharply colder Christmas Day. Graphic: Weatherspark.


Weekend Storm Midwest And Great Lakes. California is experiencing its driest year on record; the storm pushing ashore won't spark much rain. It will tap moisture from the Gulf of Mexico and fling it at the Midwest and Great Lakes, in the form of accumulating snow Saturday and Sunday. GFS model guidance above shows 10-meter wind speeds and surface pressures, courtesy of NOAA and Ham Weather.


84 Hour Snowfall. The map above shows predicted snowfall amounts into early Saturday morning; significant amounts for the central and northern Rockies and downwind of the Great Lakes, the snow just starting up from near Tulsa and Wichita to Kansas City and Moline. NAM guidance: Ham Weather.


Weekend Snow Event. GFS guidance into midday Sunday shows a stripe of 6"+ amounts from north of Kansas City to the Quad Cities, Rockford and possibly the suburbs of Chicago and Milwaukee.


Cold, But Not Nanook. Long-range GFS guidance has been all over the map with predicted temperatures, so confidence levels are low. Right now the last few days of December and first few days of 2014 look cold; highs in the teens and 20s with a few subzero nights, but not as brisk as early December. The GFS has been consistently over-doing the cold. Let's hope that's the case here as well.


Care For A Dip? Gulf stream waters are still unusually mild for mid-December; 70s off the coast of Florida, 60s are far north as the Outer Banks of North Carolina. At some point this stain of warm water may set the stage for a series of very intense Nor'easters. Stay tuned. Graphic: Wilmington, NC office of the National Weather Service.


2014 Super Bowl: Let It Snow - Just Not Too Much. We can only hope and pray for a blizzard at The Meadowlands. Because with snow on the field it's an entirely different game.  I enjoyed Sam Farmer's take on Super Bowl 2014 weather at The Los Angeles Times; here's an excerpt: "A snowbound Super Bowl? Yes, please. If last weekend's NFL games reminded us of anything, it's that snow makes everything interesting. It turns the nation's No. 1 sport into a goofy game show, with contestants struggling to perform impossible tasks, such as snapping the football or finding the line of scrimmage. Detroit fumbled seven times in a Philadelphia blizzard..."

The 10 Worst Weather Places In The World? No, Minnesota did not make the list, not even a runner-up. Weatherwise Magazine has the award nobody really wants - here's the introduction: "...Possibly due to an enduring “grass is always greener” fixation—and a craving to seek out and experience these supposed lusher pastures—many of us have a perennial fascination with “best places” lists: best places to live, work, and vacation; best places to slice into a porterhouse or dine on lobster. Often lavishly illustrated, publications of all flavors showcase the purported top beaches or resorts in a particular country or even throughout the world. In virtually all of these analyses (studies impossible to design and conduct truly objectively, of course), weather and climate play at least a salient, if not a pivotal, role. Year-round clement conditions make a good beach into a heavenly one and an otherwise unremarkable city a “quality lifestyle destination.” But what about places characterized by skyward conditions on the opposite end of the weather-comfort spectrum? What are the “worst weather places” in the world?..." (Images: Wikipedia).

Tornadoes May Be Getting Stronger - Or Not. When in doubt, obfuscate. How will a warmer, wetter, potentially more bouyant atmosphere impact the dynamics that drive tornado formation? The jury is still out, but at least one researcher believes there's a strong chance of larger tornadoes. Here's an excerpt from Scientific American: "Sometimes scientists can’t help themselves from showing dramatic curves, even though they have so many caveats that no firm conclusions can be made from the data. James Elsner at Florida State University has a killer curve, and lots of caveats. The curve indicates that tornadoes in the U.S. may be getting stronger. The caveats indicate they may not be. “If I were a betting man I’d say tornadoes are getting stronger,” he noted on Tuesday during a lecture at the annual American Geophysical Union fall meeting in San Francisco. But when asked directly at a press conference whether that is the case, he would not commit..."


Unraveling The Mysterious Impacts Of Lightning On The Human Body. Remind me not to get struck anytime soon. Here's a clip from National Geographic: "...Randolph-Quinney hopes the emerging research will help forensics investigators pinpoint cause of death from lightning. That's currently a challenge, he said, because there are 17,000 unclaimed bodies in Johannesburg-area morgues each year. When it comes to lightning injuries, there has also been little research on the mechanisms of what exactly happens to the human body when struck, other than well-established complications that can arise, such as memory loss, insomnia, and depression, said Wits electrical engineering graduate student Harry Lee...." (Photo: AP).


Does Travel Insurance Cover Weather Problems. Ed Perkins has an interesting story at The Chicago Tribune; here's the introduction: "The several big recent storms -- and the many airline cancellations that resulted -- raise the question of the extent to which travel insurance can help to recoup your travel investment. The short answer is that at least some of it does, at least sometimes. But you find lots of variation: Policies vary substantially in what they specify as "covered reasons" to provide payment. So you have to take a close look at the fine print, as well as the price, before you buy. Three different coverages apply. Trip cancellation/interruption (TCI). TCI covers whatever expenses, caused by delay or cancellation, that you can't recover from your airline or hotel..."


Moving Out Of Harm's Way. We have to worry about many forms of annoying and, at times, dangerous weather here in Minnesota. At least we don't have to worry about rising sea levels. Millions of Americans will be impacted by rising seas, as outlined in this story from The Center for American Progress. Here's a clip: "...So what are the consequences of having more ocean at our back doors? According to Princeton University earth scientist Michael Oppenheimer, who was interviewed in October by the Associated Press, 50,000 people experienced flooding from Superstorm Sandy who would have otherwise been spared in the absence of global warming. By the time the storm dissipated, it had exacted an economic cost of more than $68 billion, resulted in the deaths of 117 Americans, and taken the lives of 69 more people throughout the Caribbean and Canada. Blunting the intensity and reducing the rise in frequency of storms like Sandy is one of the most pressing reasons to reduce global greenhouse gas emissions. According to a September 2013 report from the American Meteorological Society, global-warming-caused sea-level rise is significantly reducing the time between major coastal flood events..."

How To Get The Flood Coverage You Need. Here's a snippet of a timely article at Money Magazine and CNN: "To ensure you're adequately protected against the flood damage a storm like Sandy can render, follow these tips.

Don't skimp. About 25% of flood insurance claims come from outside high-risk areas. If you live near any body of water, consider buying a policy through the National Flood Insurance Program (few private carriers offer policies). Even melted snow can cause flooding.

Brace for price shock. FEMA is phasing out subsidies for pre-1970s homes, raising rates roughly 25% a year..."

Fukushima's Worst-Case Scenario. Much Of What You've Heard About The Nuclear Accident Is Wrong. A nuclear meltdown capable of evacuating Tokyo and much of Japan? Not so much. The nuclear accident, although dangerous, never posed a significant threat to Tokyo, or U.S. forces stationed in Japan, contrary to popular media reports at the time. Kudos to Slate for some excellent original reporting on what really happened; here's an excerpt: "...Key details of this episode are revealed here for the first time, based in part on U.S. government documents released under the Freedom of Information Act. These revelations, together with additional new information, debunk some powerful myths about Fukushima and have weighty implications for the debate about nuclear power that has raged in the accident's aftermath. (The revelations are unrelated to the plant’s current water-leakage problem, which by some reckonings is less severe and more solvable than recent headlines suggest.) What was Fukushima's worst-case scenario? That question consumed the thoughts of millions of people in March 2011, and it remains highly relevant today..."

Wind Power Rivals Coal With $1 Billion Order From Buffett. Bloomberg has the story; here's the introduction: "The decision by Warren Buffett’s utility company to order about $1 billion of wind turbines for projects in Iowa shows how a drop in equipment costs is making renewable energy more competitive with power from fossil fuels. Turbine prices have fallen 26 percent worldwide since the first half of 2009, bringing wind power within 5.5 percent of the cost of electricity from coal, according to data compiled by Bloomberg. MidAmerican Energy Holdings Co., a unit of Buffett’s Berkshire Hathaway Inc., yesterday announced an order for 1,050 megawatts of Siemens AG wind turbines in the industry’s largest order to date for land-based gear.

Analysis: Clouds Over Hawaii's Rooftop Solar Growth Hint At U.S. Battle. Talk about disruptive trends; here's a good summary of how people installing solar panels on their homes (expecting a rebate or discount) are running afoul of local regulations and power utilities. Here's an excerpt from Reuters: "...What's happening in Hawaii is a sign of battles to come in the rest of the United States, solar industry and electric utility executives said. The conflict is the latest variation on what was a controversial issue this year in top solar markets California and Arizona. It was a hot topic at a solar industry conference last week: how to foster the growth of rooftop solar power while easing the concerns of regulated utilities that see its rise as a threat. The Oahu rule created a dispute between the island's solar power companies and Hawaiian Electric..."

Having A Dog Protects Against Asthma And Infection, Study Says. I've heard this before, and the data seems to suggest that there may, in fact, be a link. Here's an excerpt from a story at The PBS NewsHour: "....Dog owners already know their four-legged friend is good for their health, but they have more proof thanks to a recent study from scientists at the University of California San Francisco and University of Michigan. A study published in the Proceedings of the National Academy of Sciences found that a child's risk of developing asthma and allergies is reduced if the child is exposed to a dog in a household during infancy. While the results of the study come from mice, researchers believe the results explain the reduced allergy risk of children who were raised in homes with dogs from birth...."


5 Surprising Things That Will Happen In The Next 5 Years. Local retail will beat online shopping? And I won't have to try and remember 52 different passwords? That's one of 5 counterintuitive forecasts from IBM, highlighted in a Gizmodo story; here's a clip: "IBM Research's 5 in 5 list—five things that will happen in the next five years—is here. Some are quite surprising and awesome. The bad news: no flying cars and/or realistic sex robots yet. The good news: doctors routinely using your DNA information to heal you effectively. But even while that may seem kind of surprising, given the current state of things, their futurists are always pretty accurate—perhaps because they're scientists who base their estimates on actual data rather than dumb planet alignments and tea leaves. So, without further ado, here are five things that, according to them, you will see as normal by 2018..."

Climate Stories...

6 Ways Climate Change Is Waging War On Christmas. I found this article curious and timely, from tracking the odds of a white Christmas to reindeer to cocoa and your favorite local Christmas tree, changes in the Arctic are having an impact. Here's an excerpt from Surprising Science at smithsonian.com: "...If Santa really lived at the North Pole, he would have drowned long ago. But any fantasies we have about him making a home on floating sea ice will surely die within the century. The extent of summer sea ice in the Arctic has been shrinking, and it could be gone entirely within decades. The U.S. Navy predicts an ice-free summer Arctic as early as 2016. “We really are heading towards an ice-free Arctic in the summer,” Andreas Münchow, an Arctic scientist at the University of Delaware, told the Guardian. “It just takes a freak event eventually, in the next five or 10 or even 20 years…. The long-term trend is that the ice is disappearing in the summer in the Arctic...”

Why Our Turbulent Weather Is Getting Even Harder To Predict. This article at The Guardian is from April, but it seems more relevant and timely than ever, one (of many) possible explanations for some of the additional volatility we're seeing in weather patterns over the Northern Hemisphere, especially for weather systems to become amplified (and stuck), resulting in disastrous flooding - or drought. Here's a clip from The Guardian: "...The trouble is that the gradient between the atmosphere in the lower latitudes and in the Arctic is being disrupted by global warming," said Francis. "As the Arctic heats up disproportionately, so does the atmosphere at the north pole and as it warms up, it rises. The net effect has been to erode the gradient between the top of the atmosphere over the tropics and the top of the atmosphere over the Arctic. Less air pours down towards the north pole and less air is whipped up by Earth's rotation to form the jet stream. It is becoming less of a stream and is behaving more like a sluggish estuary that is meandering across the upper atmosphere at middle latitudes." The effects of this meandering are now being felt. As the jet stream slows, weather patterns tend to stick where they are for longer. In addition, the modest waves in the stream have increased in amplitude so that they curve north and south more frequently, bringing more weather systems northwards and southwards..."

Global Warming Explained, In About A Minute. Here's an excerpt of a very good explanation at NPR: "...Michael Ranney, the lead author on the , offers this 35-word explanation:

Earth transforms sunlight's visible light energy into infrared light energy, which leaves Earth slowly because it is absorbed by greenhouse gases. When people produce greenhouse gases, energy leaves Earth even more slowlyraising Earth's temperature.

In a second study reported in the same , Ranney and his colleagues presented college students with a somewhat longer version of this explanation (a full 400 words), and found that doing so not only increased students' understanding of global warming, but also their acceptance that it's actually occurring..."


Obama And Climate Change: The Real Story. Are actions on the ground matching the rhetoric? Bill McKibbon has the article at Rolling Stone; here's an excerpt: "...If you want to understand how people will remember the Obama climate legacy, a few facts tell the tale: By the time Obama leaves office, the U.S. will pass Saudi Arabia as the planet's biggest oil producer and Russia as the world's biggest producer of oil and gas combined. In the same years, even as we've begun to burn less coal at home, our coal exports have climbed to record highs. We are, despite slight declines in our domestic emissions, a global-warming machine: At the moment when physics tell us we should be jamming on the carbon brakes, America is revving the engine. You could argue that private industry, not the White House, has driven that boom, and in part you'd be right. But that's not what Obama himself would say..." (Photo: AP).


Global Warming: New Maps Show Temperature And Precipitation Projections Down To The County Level. Here's a clip from the Summit County Citizens Voice: "...The jury may still be out on exactly how hot the Earth will be by the end of the century, but as climate models improve, scientists are narrowing the range. In a recent effort to show changes on a regional scale, researchers with the U.S. Geological Survey and Oregon State University created a set of maps and summaries of historical and projected temperature and precipitation changes for the 21st century, down to a county level. Find your local global warming forecast here. The maps and summaries are based on NASA downscaling of the 33 climate models used in the fifth annual Climate Model Intercomparison Project and the current Intergovernmental Panel on Climate Change Assessment Report. The resulting NASA dataset is on an 800-meter grid with national coverage..."


Arctic Sea Ice - Methane Release - Planetary Emergency? Alarmist hype? I sure hope so. Could continued melting of the Arctic trigger a significant methane release? There are a number of scientists concerned about this. Again, it's the "unknown unknowns", the tipping points in the climate system we're not aware of (yet) that keep a lot of researchers up at night. Here's an excerpt from The Arctic Methane Emergency Group: "...Research from US scientist, Jennifer Francis, suggests that the retreat of sea ice is causing a disruption of jet stream behaviour, producing weather extremes.  Evidence was given to the UK government last year that the weather extremes being experienced in the UK and elsewhere could be due to this disruption of weather systems as the Arctic warms relative to the tropics.  This evidence was reported by Robin McKie in the Observer, on 7th April in an article entitled: “Why our turbulent weather is getting harder to predict”. The weather extremes from last year are causing real problems for farmers, not only in the UK, but in US and many grain-producing countries.  World food production can be expected to decline, with mass starvation inevitable.  The price of food will rise inexorably, producing global unrest and making food security even more of an issue..."


Snow On Italian Alps Melting At "Unprecedented Rate", Ohio State University Study Finds. Here's an excerpt of an update from International Business Times: "...A six-nation team of glaciologists, led by Ohio State University, drilled a set of ice cores above the Alto dell’Ortles glacier in northern Italy and found that, for the first time in thousands of years, the glacier had shifted from a state of constantly below-freezing to one where its upper layers were at -- note below -- a melting point. “Our first results indicate that the current atmospheric warming at high elevation in the Alps is outside the normal cold range held for millennia,” Paolo Gabrielli, research scientist at Byrd Polar Research Center at Ohio State said. “This is consistent with the rapid, ongoing shrinking of glaciers at high elevation in this area...” (Image: NASA).


Reddit's Science Forum Banned Climate Deniers. Why Don't All Newspapers Do The Same? Here's a clip from Grist: "...Instead of the reasoned and civil conversations that arise in most threads, when it came to climate change the comment sections became a battleground. Rather than making thoughtful arguments based on peer-reviewed science to refute man-made climate change, contrarians immediately resorted to aggressive behaviors. On one side, deniers accused any of the hard-working scientists whose research supported and furthered our understanding of man-made climate change of being bought by “Big Green.” On the other side, deniers were frequently insulted and accused of being paid to comment on reddit by “Big Oil.” After some time interacting with the regular denier posters, it became clear that they could not or would not improve their demeanor. These problematic users were not the common “internet trolls” looking to have a little fun upsetting people..."

Water Scarcity Seen Worsening As Climate Changes, Study Shows. Here is one of many implications and complications of a warming, more volatile climate - as described in this story at Bloomberg BusinessWeek; here's an excerpt: "Climate change will increase the number of people at risk of absolute water scarcity by 40 percent this century, according to a German institute. Ten in 100 will have less than 500 cubic meters (132,000 gallons) of water available a year, up from 1-2 today, should Earth warm by 3 degrees Celsius (5.4 degrees Fahrenheit) above pre-industrial levels and populations grow, according to the Potsdam Institute for Climate Impact Research. The global average is about 1,200 cubic meters, and much greater in industrialized nations, PIK said, citing its and other analysts. “Water scarcity is a major threat for human development as for instance food security in many regions depends on irrigation,” said Qiuhong Tang of the Chinese Academy of Sciences, who co-wrote the study. “Agriculture is the main water user worldwide...”


The Global Temperature Jigsaw. More on the alleged temperature "pause" from RealClimate: "...First an important point: the global temperature trend over only 15 years is neither robust nor predictive of longer-term climate trends. I’ve repeated this now for six years in various articles, as this is often misunderstood. The IPCC has again made this clear (Summary for Policy Makers p. 3):

Due to natural variability, trends based on short records are very sensitive to the beginning and end dates and do not in general reflect long-term climate trends.

You can see this for yourself by comparing the trend from mid-1997 to the trend from 1999 : the latter is more than twice as large: 0.07 instead of 0.03 degrees per decade (HadCRUT4 data)..."

Are Hurricanes Getting Stronger? Science May Finally Be Approaching An Answer. Mother Jones has a very interesting article that caught my eye - here's an excerpt: "...The result? The scientists found that globally, hurricane wind speeds are increasing at a rate of a little more than two miles per hour per decade, or just faster than six miles per hour over the entire period. There are some key caveats, though, the biggest being that the trend they found was not statistically significant at usually accepted levels. (For nerds: the p value was 0.1). But there were strong and significant trends in some hurricane basins of the world, especially the North Atlantic (the region encompassing the Caribbean, Gulf of Mexico, and open Atlantic north of the equator), where storms have been strengthening at the rate of nearly nine miles per hour per decade (see chart above). But other basins offset that, including the western North Pacific, which showed a negative trend..."


Faux Pause 2: Warmest November On Record, Reports NASA, As New Studies Confirm Warming Trend. Here's an excerpt of a good explanation from ThinkProgress: "

A new study by British and Canadian researchers shows that the global temperature rise of the past 15 years has been greatly underestimated. The reason is the data gaps in the weather station network, especially in the Arctic. If you fill these data gaps using satellite measurements, the warming trend is more than doubled in the widely used HadCRUT4 data, and the much-discussed “warming pause” has virtually disappeared.

“There are no permanent weather stations in the Arctic Ocean, the place on Earth that has been warming fastest,” as New Scientist explained five years ago. “The UK’s Hadley Centre record simply excludes this area, whereas the NASA version assumes its surface temperature is the same as that of the nearest land-based stations...”

New Climate Records Focus On Earth's Sensitivity. Here's a clip from a story at Climate New Network and Climate Central: "...The Geological Society of London (GSL) says the sensitivity of the Earth’s climate to CO2 could be double earlier estimates. The Society has published an addition to a report by a GSL working party in 2010, which was entitled Climate Change: Evidence from teh Geological Record. The addition says many climate models typically look at short term, rapid factors when calculating the Earth’s climate sensitivity, which is defined as the average global temperature increase brought about by a doubling of CO2 in the atmosphere..."

More Cold Canadian Spam (will December be the coldest month of winter?)

Posted by: Paul Douglas Updated: December 10, 2013 - 9:29 AM

Southern Daydreams

Canada is spamming us with more arctic air, and it's getting harder to mock the snowbirds who flee south every winter. I get regular calls & e-mails from Florida friends, sharing the predicted high temperature for the day. Very thoughtful. I return the favor by sharing coordinates of major hurricanes during the summer months.

With a son in the Navy near Pensacola we've had a chance to explore the Sunshine State, and I'm going to let you in on a secret. If you're tired of the congestion & traffic gridlock consider 30-A, South Walton County, on the Panhandle. Not as warm in January. Not as crazed either.

Sometimes the thought of a sunny, southern vacation is almost as good as the getaway itself. Right now I'd settle for Dubuque.

A family of clippers drags more bitter air south of the border into midweek; 20 (above) feels like sweet relief by late week.

Models show a subzero swipe early next week, followed by a Pacific reprieve next week as steering winds turn more westerly. That should mean 30s within 8-9 days. NOAA's 45-day CFS model hints at a mild bias returning much of January.

Perhaps that's wishful thinking. At least we'll have a (very) white Christmas this year.


66.9% of USA Has Snow On The Ground. That compares to 26% of the USA last year at this time. Yes, a fast-forward winter this year - maybe it won't extend into May, like it did this year. Map: NOAA.


A December To Remember - Or Forget. Arctic chill lingers into midweek, with some slight temperature recovery by late week. Sad when 20F constitutes "recovery". Another arctic relapse is expected early next week, followed by more of a Pacific influence in a little over a week; maybe a few 30s by the middle of next week? Wouldn't that be nice. Graph: Weatherspark.


The Big Leak. Harsh air of Siberian origin continues to lap south of the border in waves, skirting the northern USA in the coming days. The solid green line shows the 0F isotherm; unusually chilly weather impacting the entire USA (even Florida) by midweek. Hard Freeze Warnings are posted as far south and west as Las Vegas and Phoenix. NAM 2 meter temperature guidance courtesy of NOAA and Ham Weather.


Ill-Timed Snow Burst Out East. Today's clipper sparks a stripe of accumulating snow from Iowa into Illinois, and a second, stronger wave of low pressure rippling along the leading edge of bitter air drops 3-6" of snow from Washington D.C. to Philadelphia and Wilmington. Not a good day to be traveling out east. 4 km. NAM Future Radar product courtesy of NOAA and Ham Weather.


45 Day Wish-Cast. I'm keeping an eye on NOAA's 45 day (CFS, for Climate Forecast System) model trend, which has actually been showing more skill than I thought it would. It shows a slight warming trend thru December 20, then much colder weather returning for Christmas, a potential for a mild bias by the middle of January. Don't hold your breath. Data: NOAA and Ham Weather.


45-Day Snow Cover. Odds still favor a white Christmas this year - we may lose a little of our snowcover by December 24 (down to 2-3" according to the CFS model), which predicts 5" around New Year's Eve and a whopping 12" by the middle of January. A good winter to invest in cross country skis or a sturdy snowmobile. Graph: Ham Weather.


Alerts Broadcaster Briefing: Issued Monday evening, December 9, 2013.

* Another significant burst of snow is likely Tuesday for major urban centers from Washington D.C. and Baltimore to Philadelphia and New York, slightly lesser amounts across southern New England and metro Boston.

* Band of 3-6" likely D.C. to Philadelphia with locally heavier 6"+ amounts possible; best chance of snow morning and midday hours. I expect 2-4" in metro New York City. Expect significant air delays and cancellations from Dulles and Reagan National in D.C. to La Guardia, Newark and JFK in New York City Tuesday.

* Impacts to air/land travel likely - I envision extremely slow commutes - and facilities within 100 miles of the I-95 corridor will see snowy impacts from this system. Little or no ice expected; the atmosphere should be cold enough for all-snow.


Brewing Tuesday Travel Headaches. Major interstates are in fairly good shape this evening, but this will change, dramatically, within 12-15 hours as another surge of snow pushes across the Mid Atlantic Region into southern New England. Click here for real-time traffic reports, courtesy of Google.


Narrow Band Of Significant Snow. Our internal models show as much as 6-8" for the wester and southwestern suburbs of Washington D.C., a band of plowable snow from Charlottesville and D.C. to Baltimore, Wilmington, Philadelphia, much of New Jersey and metro New York City. Map: Ham Weather.


Heaviest Snow Band. Other models show similar solutions, the axis of heaviest snow from near Washington D.C. to Harrisburg and Philadelphia, but a broad area of the Mid Atlantic and Northeast picking up at least 2-3". With temperatures in the upper 20s and low 30s even interstates will become snow-covered and slippery. Map: WSI.


Blizzard Potential Index. Alerts Broadcaster's internal BPI model shows a 6-8 hour burst of near-blizzard conditions spreading northeastward Tuesday from D.C. to south Jersey and Long Island; visibilities may drop below 1/2 mile in moderate snow, winds of 20-25 mph. It won't be the classic definition of a blizzard, but travel conditions will range from poor to treacherous by morning and midday from D.C. to Philadelphia, pushing into New York City during the midday and afternoon hours. Map: Ham Weather.


Select City Amounts. Models print out as much as 6" for Washington D.C., 5" for Baltimore and 4-5" for Philadelphia, with 3-4" possible for New York City and suburbs during the day Tuesday.


Advisories and Warnings. NOAA has issued Winter Storm Warnings for the Delaware Valley, which may have to be extended into Baltimore and Washington D.C. Winter Weather Advisories are in effect from the Virginia and Maryland into eastern Pennsylvania, New Jersey and New York City. Map: Ham Weather.


A Nagging Frontal Zone. Winter Weather Advisories extend from southeast Arkansas and northern Mississippi into eastern Kentucky and the Shenandoah Valley of Virginia, calling for a couple of inches of additional snow and ice.

Summary: A few weeks ago we warned of an active and wintry pattern for much of the East Coast, and that forecast seems to be verifying as a series of storms ripple along the leading edge of Arctic air. One such ripple of low pressure will squeeze out plowable amounts of snow from northern Virginia to New York City, with lesser amounts for Providence, Hartford and Boston. I'm especially concerned about Washington D.C. and suburbs, where mere flurries can wreak havoc. Tuesday will be a very forgettable travel day in the nation's capital, with considerable impacts into Philadelphia and even metro New York City.

Federal Flood Maps Left New York Unprepared For Sandy - And FEMA Knew It. Here's a remarkably damning story from ProPublica - it turns out budget cuts can have a significant impact, even on something as mundane (yet critically important) as FEMA flood maps. Here's a clip: "...But the maps drawn up by the Federal Emergency Management Agency were wrong. And government officials knew it. According to documents and interviews, state, local and federal officials had been aware for years that the crucial maps of flood risks were inaccurate; some feared they understated the dangers in New York City’s low-lying areas. The flaws in the maps had significant impact. Developers relied on FEMA’s assessment of risks when they built new homes near the water. And homeowners and businesses made crucial decisions about where to buy or lease property on the assurance that they were outside of the high-risk zones..."


Critical Weather Forecasting Bill Moves One Step Closer. Some encouraging news from Climate Central; here's an excerpt: "...The bill, known as the “Weather Forecasting Improvement Act,” now heads to the full House for consideration. If it passes, and there are no guarantees given the small window left in the legislative calendar, it would be the first broadly focused weather bill to be enacted by Congress since the mid-1990s. The bill would establish a research program within the National Oceanic and Atmospheric Administration (NOAA) to extend the lead time for tornado warnings beyond 1 hour, and contains provisions aimed at closing the performance gaps between the agency’s weather forecasting computer models and those of other nations..."

Smog? It Bolsters Military Defense, Says Chinese Nationalist Newspaper. This is one of the greatest samples of spin and rationalization I've ever encountered. Smog is GOOD for you! Uh huh. Here's an excerpt from The South China Morning Post: "A nationalist newspaper has tried to put a positive spin on China’s smog, claiming it is conducive to the country's military defence strategy. Smog, it argued, could thwart missile attacks and hamper hostile reconnaissance. “Smog may affect people’s health and daily lives … but on the battlefield, it can serve as a defensive advantage in military operations,” said an article on the website of Global Times, a nationalist newspaper affiliated to the Communist Party’s mouthpiece the People’s Daily. Missile guidance that relies on human sight, infrared rays and lasers could be affected by smog in varing degrees, the article said. It explained that tiny particles in the air contributing to air pollution could hinder missile guidance systems..."

Extreme Summer Weather In Northern Mid-Latitudes Linked To A Vanishing Cryosphere. It turns out all that melting ice in the arctic may, in fact, be having a domino effect at our latitude. Here's an excerpt of a technical, but fascinating paper at Nature: "The past decade has seen an exceptional number of unprecedented summer extreme weather events in northern mid-latitudes, along with record declines in both summer Arctic sea ice and snow cover on high-latitude land. The underlying mechanisms that link the shrinking cryosphere with summer extreme weather, however, remain unclear. Here, we combine satellite observations of early summer snow cover and summer sea-ice extent with atmospheric reanalysis data to demonstrate associations between summer weather patterns in mid-latitudes and losses of snow and sea ice. Results suggest that the atmospheric circulation responds differently to changes in the ice and snow extents, with a stronger response to sea-ice loss, even though its reduction is half as large as that for the snow cover..."


Arctic Ice Melt Tied To Heat Waves And Downpours In U.S., Europe And Elsewhere, Study Suggests. Following up on the new research findings above here's an excerpt of a good summary at Reuters: "A thaw of Arctic ice and snow is linked to worsening summer heatwaves and downpours thousands of miles south in Europe, the United States and other areas, underlying the scale of the threat posed by global warming, scientists said on Sunday. Their report, which was dismissed as inconclusive by some other experts, warned of increasingly extreme weather across "much of North America and Eurasia where billions of people will be affected". The study is part of a drive to work out how climate change affects the frequency of extreme weather, from droughts to floods. Governments want to know the trends to plan everything from water supplies to what crops to plant. But the science of a warming Arctic is far from settled..."


Solar Would Be Cheaper: U.S. Pentagon Has Spent $8 Trillion To Guard Gulf Oil. Here's an eye-popping number. Trillions of dollars and the lives of too many members of our armed services. Here's an excerpt from Informed Consent: "...It has cost the United States $8 trillion to provide military security in the Gulf since 1976. According to Roger Stern, a Princeton economist, the US has spent as much on Gulf security as it spent on the entire Cold War with the Soviet Union! In recent years through 2010 it has been $400 billion a year, though the US withdrawal from Iraq at the end of 2011 and the gradual withdrawal from Afghanistan this year and next presumably means that the figure is substantially reduced. Still, we have bases in Kuwait, Qatar and elsewhere, and a Naval HQ in Bahrain, none of which is cheap. If it were $200 billion a year, that is a fair chunk of the budget deficit the Republican Party keeps complaining about. And if we could get that $8 trillion back, it would pay down half of the national debt..." (Photo: Wikipedia).


Solar Panels Could Destroy U.S. Utilities, According To U.S. Utilities. Here's an excerpt of an April post from Grist, which is just as relevant as ever: "Solar power and other distributed renewable energy technologies could lay waste to U.S. power utilities and burn the utility business model, which has remained virtually unchanged for a century, to the ground. That is not wild-eyed hippie talk. It is the assessment of the utilities themselves. Back in January, the Edison Electric Institute — the (typically stodgy and backward-looking) trade group of U.S. investor-owned utilities — released a report [PDF] that, as far as I can tell, went almost entirely without notice in the press..."

What We Owe Our Kids On Climate. NASA climate scientist James Hansen has the Op-Ed at CNN; here's an excerpt: "...Carbon emissions will decline only if the price of fossil fuels begins to include their costs to society: their effects on human health and climate. Economic analysis shows that a rising carbon fee collected from fossil fuel companies would swiftly drive market innovations and investments in clean energy. (Indeed, many companies are preparing for such a fee.) Courts cannot tell the government how to reduce emissions. But they can require that the government provide a plan: How will emissions be reduced to assure that the rights of young people are protected?..."
