"I love being married. It's so great to find that one special person you want to annoy for the rest of your life" said comedian Rita Rudner.
What's it like being married to a weatherman? "Mostly sunny with occasional storms" my wife sighed. "I prefer sunshine". Laurie and I are heading to Dublin, Ireland to celebrate our 30th anniversary, watch some college football and enjoy occasional showers of Guinness. Volcano-permitting, that is.
I'm tracking the grumbling Bardarbunga volcano in Iceland, which may blow its top at any moment. A major Icelandic eruption in 2010 grounded millions of air travelers over 8 days, costing airlines nearly $2 billion. Dubuque is looking better & better. Cheaper too.
Yesterday's thundery frontal zone is pushing east; Canadian exhaust dropping humidity levels back down to tolerable levels. Dew points tumble into the 40s by midweek, meaning HALF as much water floating overhead. It now looks like showers stay south of Minnesota until Thursday & Friday, with a holiday weekend clearing trend and highs near 80F. A few storms may pop (right on schedule) on Labor Day.
What can possibly go wrong?
I can almost promise a lack of flurries.
Sunday Severe Weather Reports. Funnel clouds were spotted near Rice, with tornado touchdowns at Granite Ledge (Benton County) and damage in the Gilman area. Elsewhere large hail was spotted just east of Brainerd, flash flooding near Fergus Falls and reports of storm-related wind damage east of Alexandria. A trained spotter reported 2.2" diameter hail 7.5 miles south of Hillman, in Morrison County, around 6 PM. The Twin Cities National Weather Service has an interactive map. Additional storm reports are here.
Late August Supercells. Sunday's late afternoon visible cloud loop shows the squall line that sprouted over central Minnesota, the most severe cells from near Brainerd to just north of St. Cloud. By late August the atmosphere is usually more stable (cooling near the surface, still warm aloft), so tornadic storms are unusual, but certainly not unprecedented. Imagery: NOAA and HAMweather.
Cristobal Stalks the Bahamas - Heavy Storms Push into the Great Lakes. The 60-hour accumulated rainfall map shows some heavy 2-4" amounts from near Wausau to near Madison and Chicago as slightly cooler air pushes east. This weak frontal zone stalls, sparking more heavy rain across Iowa by Tuesday and Wednesday. 4 KM NAM data: NOAA and HAMweather.
Trending Comfortable. Sick of dreadful dew points hovering near 70F? You're in luck. Canadian air drops moisture levels significantly, less than half as much water in the air by this time Tuesday. Dry weather should prevail today into Wednesday, the next surge of warm air sparking a few showers and T-showers Thursday and Friday. Long-range guidance shows some weekend clearing, with the best chance of rain (and storms) on Labor Day. With any luck the forecast will change as new data comes in.
Alerts Broadcaster Update. Here's an excerpt of a briefing that went out Sunday:
* Tropical Storm Cristobal intensifying - will impact Bahamas with tropical storm force conditions over the next 24 hours.
* All models show a track that keeps the core of Cristobal's strongest winds and storm surge at sea this week.
* Dangerous rip tides and some minor coastal flooding can't be ruled out across the Carolina coast Wednesday and Thursday of this week, especially close to high tide.
Better Organized. Satellite imagery shows a more symmetric storm circulation, less wind shear will favor additional strengthening in the coming days; Cristobal expected to become a Category 1 hurricane well east of the Carolinas late Wednesday night or Thursday morning.
Projected Track. NOAA's National Hurricane Center shows a track to the north/northwest into Wednesday, followed by a northeastward turn which should keep the brunt of Cristobal out at sea; but uncomfortably close for North Carolina's Outer Banks.
Rapid Intensification by Thursday. Warm Atlantic ocean water will fuel further intensification, and the ECMWF (European) model shows a potential for a Category 1-2 hurricane the latter half of this week with additional strengthening as Cristobal veers out to sea. Map: WSI.
General Model Agreement. Although far from perfect, models are all displaying a version of the solution, keeping Cristobal's core out to sea with a turn to the northeast after 96-120 hours. No models (we trust) are bringing Cristobal toward a U.S. landfall at this time.
Summary: We've been watching the evolution of Cristobal, and expect minor to moderate impact over the Bahamas today, especially Great Abaco and Grand Bahama (including the city of Freeport). Flash flooding is expected with winds in the 35-50 mph range in squalls over the next 24 to 36 hours. All computer solutions keep Cristobal's core of strongest winds, heaviest rains and highest storm surge east of the U.S. mainland, but minor lowland flooding is still possible along the Carolina coast by midweek - especially at local high tide. We'll keep an eye on Cristobal and keep you posted should there be a material change to our predictions.

Hurricane Marie Now a Category 5 Off The Mexican Coast. Mercifully it is not expected to make landfall. More details at Gawker's The Vane: "Hurricane Marie is now a powerful Category 5 hurricane as it churns off the Mexican coast this evening, packing sustained winds of around 160 MPH. The eastern Pacific hurricane rapidly strengthened from a Category 1 to a Category 5 in just 24 hours. The intense storm is the fifth major hurricane to form in the basin so far this year, and Marie is the eastern Pacific's first hurricane to reach Category 5 intensity in more than four years. Thankfully, the hurricane will weaken as it continues to move northwest away from land..."
Farmer's Almanac Predicts "Super Cold" Winter, More Snow in Eastern U.S. I'm always shocked when Minnesota doesn't experience a super-cold winter. Take any long range forecast with a massive grain of salt, but I am going on record stating the odds of something similar to last winter's polar vortex are slim to nil. Cold with significant snow? Absolutely, but not the extreme levels of cold we endured last winter. Here's an excerpt from Huffington Post: "The Old Farmer's Almanac, the familiar, 223-year-old chronicler of climate, folksy advice and fun facts, is predicting a colder winter and warmer summer for much of the nation. Published Wednesday, the New Hampshire-based almanac predicts a "super-cold" winter in the eastern two-thirds of the country. The west will remain a little bit warmer than normal..."
Researchers Dig Deeper Into Tornado Winds, Building Damage. Here's a clip from an interesting line of research described at The Ames Tribune: "...By measuring on the Enhanced Fujita (EF) Scale, which evaluates storm damage to measure the strength of tornadoes, around 90 percent of all tornadoes are an EF3 or less. Sarkar, who has been at ISU for 14 years, believes the strength of tornado winds is debateable. The scale of a tornado is only determined after the damage has been examined. There are also many other factors that can throw off an examination such as the building's age, the material strength, construction quality and prior weaknesses caused by debris..."

Iceland Volcano Experts: No Eruption Yet. As they say, the "situation is fluid". As in magma-fluid, and at some point that lava may reach the surface, like an enormous, angry pimple. The impact to trans-Atlantic flights is still unclear, but if history is a guide there could be serious implications in the coming weeks. Here's an excerpt of an update from a good source of local information, RUV: "...The most likely scenario is that an eruption has not begun. This morning we saw a large increase in seismic activity and tremors, so it was perfectly rational to assume that an eruption had begun. A subglacial eruption melts the ice and causes floods. We surveyed the glacier for three hours today. I can of course not assert that nothing has happened, but it is clear that there are no signs of abnormal melting or other signs that normally appear during a subglacial eruption..."

What It Feels Like To Be The Last Generation To Remember Life Before The Internet. Are you old enough to remember a time before Netscape Mozilla's crude web browser and AOL "You've Got Mail"? Me too. I miss those simpler days when people used rotary phones and there was a place where you could gather to talk to your friends. It was called a "bar". That's why this story at Quartz caught my eye; here's a clip: "Technology has a lot to answer for: killing old businesses, destroying the middle class, Buzzfeed. Technology in the form of the internet is especially villainous, having been accused of everything from making us dumber (paywall) to aiding dictatorships. But Michael Harris, riffing on the observations of Melvin Kranzberg, argues that “technology is neither good nor evil. The most we can say about it is this: It has come...”

"Incredible" Rate of Polar Ice Loss Alarms Scientists. Here's an excerpt from The Guardian: "The planet's two largest ice sheets – in Greenland and Antarctica – are now being depleted at an astonishing rate of 120 cubic miles each year. That is the discovery made by scientists using data from CryoSat-2, the European probe that has been measuring the thickness of Earth's ice sheets and glaciers since it was launched by the European Space Agency in 2010. Even more alarming, the rate of loss of ice from the two regions has more than doubled since 2009, revealing the dramatic impact that climate change is beginning to have on our world..."

What Iceland's Volcanoes Can Teach Us About Climate. Here's a brief excerpt from an interesting story at Climate Central: "...Glacial volcano research also helps improve climate change modeling by preserving a record of ice sheets that melted long ago.

Climate Change and Drought Are Forcing Us to Upgrade our Water Systems. Public Radio International has an interesting article and interview, talking about the need to upgrade from Water 1.0 to Water 4.0. Here's a clip: "...Throughout history, he says, each time we have encountered seemingly intractable problems with water supply, we have found solutions. We create and adapt to new technologies and we “become comfortable with water that’s treated, or sewage that’s treated, or water that’s imported.” We're already familiar with one of the tenets of Water 4.0 — conservation. “Quietly, over the last 10 or 20 years, we’ve seen indoor plumbing change as people are, for example, switching out their top-loading washing machines for front-loading washing machines,” Sedlak points out. “We’ve saved a lot of water that way. [But] we can do better and we will do better...”

The Climate Swerve. The New York Times had an Op-Ed comparing the specter of climate change and impacts on future generations to nuclear proliferation and the prospect of nuclear war in the 1980s. Here's a clip: "...The experiential part has to do with a drumbeat of climate-related disasters around the world, all actively reported by the news media: hurricanes and tornadoes, droughts and wildfires, extreme heat waves and equally extreme cold, rising sea levels and floods.

Of great importance is the growing recognition that the danger encompasses the entire earth and its inhabitants. We are all vulnerable..."
Climate Change and Implications for National Security. Here's an excerpt of a story at International Policy Digest: "...Over the 250 years carbon fuels have enabled tremendous technological advances including a population growth from about 800 million then to 7.5 billion today and the consequent demand to extract even more carbon. This has occurred during a handful of generations, which is hardly noticeable on our imaginary one-year calendar. The release of this carbon – however – is changing our climate at such a rapid rate that it threatens our survival and presence on earth. It defies imagination that so much damage has been done in such a relatively short time. The implications of climate change are the single most significant threat to life on earth and, put simply, we are not doing enough to rectify the damage..."

Kansas' Climate Change Debate Settled in Europe. While Americans debate the science much of Europe is moving forward with plans to scale back the use of fossil fuels. What's missing here? Environmentally-minded Americans who care about this issue have yet to band together and exert political pressure. That will change in the years ahead (with our kids and grandkids out in front). Here's an excerpt from CJOnline.com: "...One of the key differences, King said, is the influence of Green parties within European nations. To get action on climate change, he said, environmentally-minded Americans must increase their influence in the political sphere. In Germany, the Greens hold about 10 percent of the seats in a 631-member parliament made up of five parties. Oliver Krischer, vice chairman of the German Green Party’s parliamentary group, said he hasn’t heard members of other parties say they believe human-caused climate change is a myth. “There might be some colleagues in the Bundestag that think so,” Krischer said. “You cannot look in their heads. But there is at least nobody that says climate change is an invention of some scientists...”

The urban heat island is real; cities are hotter than surrounding suburbs. That's why climate records are maintained at sites well away from the asphalt and concrete of city cores.
The planet is warming, but cities are heating up much faster. A new report from Climate Central finds that the Twin Cities metro has the 9th most intense summer urban heat island of America's top 60 cities, with a daily average rural-urban temperature difference of 4.3F. Las Vegas is at the top of the list; The Strip a whopping 7.3F warmer than surrounding deserts.
80 percent of Americans live in cities and the urban heat island is heating up our metro areas much faster than rural areas. Details on the blog below.
Clouds kept us a bit cooler yesterday, but hazy sun should lure the mercury well into the 80s today and Saturday; low 90s possible Sunday with a debilitating dew point near 70F. Serious Dog Days.
I expect a dry sky at the State Fair today and much of tomorrow; a few storms rumble in late Saturday.
Mother Nature appears manic: a sizzling Sunday gives way to fresh air by midweek - lows near 50F by Thursday. Heat builds again late next week as 80s return.
Summer spills into September this year.
Getting Sunnier. This morning's fog and stratus has been slow to burn off, but the 1 KM visible loop shows drier air eroding stubborn low clouds over east central Minnesota - a good chance of spying the sun by the dinner hour into this evening (no T-storms expected). Loop: HAMweather.

Hot And Getting Hotter: Heat Islands Cooking U.S. Cities. Climate Central highlights the large (and growing) difference in temperature between the downtown urban core, experiencing additional heating from asphalt and concrete surfaces, versus outlying suburbs. The differences on a sunny, summer day can be extraordinary, as much as 10-20F. or more. Here's an excerpt: "...With more than 80 percent of Americans living in cities, these urban heat islands — combined with rising temperatures caused by increasing heat-trapping greenhouse gas emissions — can have serious health effects for hundreds of millions of people during the hottest months of the year. Heat is the No.1 weather-related killer in the U.S., and the hottest days, particularly days over 90°F, are associated with dangerous ozone pollution levels that can trigger asthma attacks, heart attacks, and other serious health impacts. Our analysis of summer temperatures in 60 of the largest U.S. cities found that: 57 cities had measurable urban heat island effects over the past 10 years. Single-day urban temperatures in some metro areas were as much as 27°F higher than the surrounding rural areas, and on average across all 60 cities, the maximum single-day temperature difference was 17.5°F..."
Saved By Stubborn Cumulus. A Heat Advisory was issued for a time yesterday from the southern suburbs into south central Minnesota as overheated air pushed into Minnesota. But lingering clouds kept temperatures cooler than they would have been had the sun stayed out for a few hours. There was enough instability for T-storms to bubble up; one sparked a possible tornado touchdown near Mountain Lake at 5:20 PM yesterday. Visible loop: HAMweather.
Drier Friday - Late Saturday Storm Risk. 4 KM NAM model data from NOAA shows the next wave of heavy T-storms rumbling across Minnesota late Saturday and Saturday night, but today should be partly sunny and dry with a light north/northeast breeze. Heat spikes Sunday (low 90s?) before a big cool-down early next week. 60-hour accumulated rain loop: HAMweather.
A Serious Case of the Stickies into Sunday. Long-range guidance shows a dew point in the upper 60s to near 70 today into Sunday, followed by a whiff of Canadian air much of next week as dew points tumble into the 40s and 50s. Storms are possible late Saturday, likely late Sunday as cooler air approaches; another round of showers Tuesday, especially southern Minnesota. We dry out Wednesday - Friday of next week as temperatures slowly warm up. I could see a few sweatshirts coming out up north by Thursday morning.
Ramsey, Hennepin Among Counties Getting Flood Assistance. Many areas are still cleaning up and repairing flood damage from June's onslaught of rain. June was the wettest month in recorded Minnesota history, statewide, and 37 counties are now getting assistance from FEMA. Here's more from The Star Tribune: "Hennepin and Ramsey counties will be eligible for federal funds for emergency relief and reconstruction following flooding in June, the Federal Emergency Management Agency (FEMA) announced Thursday. That brings the number of Minnesota counties receiving flood assistance to 37, plus three tribal governments. Dakota County is still assessing its damages, according to state officials..."

Here's an excerpt of an in-depth look at ENSO and what will probably still be a mild to moderate El Nino event later in 2014 and early 2015, courtesy of International Research Institute for Climate and Society at Columbia University: "...Most of the set of dynamical and statistical model predictions issued during late July and early August 2014 predict a transition from neutral ENSO conditions to weak El Nino conditions during northern early fall 2014 with some further warming predicted into late fall and winter 2014-15. Development of El Nino conditions appears approximately 50% likely for the Aug-Oct or Sep-Nov seasons of 2014, and rises to 70-75% by Nov-Jan and Dec-Feb 2014-15..."
63 Trillion Gallons of Groundwater Lost in Drought, Study Finds. This story at The Los Angeles Times provides perspective, and a few staggering statistics; here's a clip: "The ongoing drought in the western United States has caused so much loss of groundwater that the Earth, on average, has lifted up about 0.16 inches over the last 18 months, according to a new study. The situation was even worse in the snow-starved mountains of California, where the Earth rose up to 0.6 inches. Researchers from UC San Diego’s Scripps Institution of Oceanography and the U.S. Geological Survey estimated the groundwater loss from the start of 2013 to be 63 trillion gallons — the equivalent of flooding four inches of water across the United States west of the Rocky Mountains..."

Hurricane Hype Is Here To Stay - Forecasters Must Adapt. Because now everyone is an armchair meteorologist, and can tweet information that is dubious or outright malicious. I echo many of meteorologist Jason Samenow's concerns over at Capital Weather Gang; here's an excerpt of what he had to say about recent hurricane-hype: "...Many weather communicators want the public to understand the full range of possibilities. We want the public to appreciate that model simulations for storms more than five days into the future aren’t realistic. We lament that armchair meteorologists (amateurs, students, novices, etc.) post unreliable model simulations on social media – without any context - of a storm obliterating a coastal city. We cringe when these suspect forecasts are shared thousands of times, misleading an unknowing public. While some us are secretly envious of the attention, we ultimately worry about a loss of public trust in weather forecasting when they are wrong (most of the time)..."

New Study Reveals The Lingering Economic Devastation Left by Hurricanes. The negative impact from hurricanes can linger not only years, but decades after a major strike. Here's an excerpt of a story that caught my eye, courtesy of Business Insider Malaysia: "... A full fifteen years after a hurricane or typhoon strikes a country, that country’s per capita GDP will be lower by 0.38% for each meter per second of top wind speed than it would have been without the cyclone. So, a storm whose top wind speed was 10 m/s, or about 22 miles per hour, would have its per capita GDP lowered by about 3.8% fifteen years later, compared to a stormless baseline. The authors also note that cyclones have a much more severe effect on countries with multiple storms. Because each hurricane or typhoon negatively affects GDP in the long term, multiple storms over a period of time can have effects that add up..."

Using GPS To Improve Tropical Cyclone Forecasts. Here's an excerpt of a forecast from UCAR in Boulder, Colorado focusing on promising new technology that may be able to help pinpoint cyclone track and intensity: "One of the challenges in forecasting tropical cyclones is that measuring atmospheric conditions over the open ocean is extremely difficult. New research indicates that the COSMIC microsatellite system, which uses a technology known as GPS radio occultation to observe remote regions of the atmosphere, can significantly improve predictions of tropical cyclones. Forecasts traditionally draw on observations taken by instruments on Earth’s surface or by radiosondes, which are lifted into the atmosphere by balloons. But both these approaches are limited in hard-to-access places, like the open ocean. In contrast, GPS radio occultation measurements can be made almost anywhere, and they are unaffected by clouds, light rain, or airborne aerosols..."

How The "Year of Four Hurricanes" Changed Florida's Readiness. New communications tools exist that weren't around 10 years ago, but amazing platforms like cell phone texts, Twitter and Facebook can transmit not only essential, accurate information and warnings, but also rumor, inuendo and misinformation. Here's an excerpt of what's changed (for the better) from Emergency Management: "...Communications: When the 2004 storms struck, Twitter did not exist. Neither did the iPhone. A new website called TheFacebook had just been created in a Harvard dorm room. When it came to hurricanes, the latest news arrived via television, the Web and radio. Today, when a storm gets close, text alerts will go out to anyone within range of South Florida cellphone antennas, even if their phone has a Cleveland or New York City area code. Emergency managers also plan to rely heavily on social media to get the word out. At the Broward County Emergency Operations Center, about 40 volunteers have been trained to monitor Facebook and Twitter for information on people trapped, in need of food or dealing with other emergency situations, said emergency manager Miguel Ascarrunz..."

Twins: A Gold Mine for Research. I married a twin. And no, I don't get them confused. That could be fatal. Here's an excerpt of a fascinating tale from The Atlantic: "This is one party where virtually no one shows up alone. Two thousand sets of twins packed into the small city of Twinsburg, Ohio earlier this month to celebrate their twin-ness at a three-day festival called Twins Days. Throughout the weekend, twins marched in the “Double Take” parade, competed in look-alike contests, and snapped photos with one another at a welcome wiener roast on Friday night. Though the festival is meant for twins, there is another group that is just as eager to attend this annual celebration of shared genetics—scientists..."

Jet Stream Changes Driving Extreme Weather Linked Again to Global Warming, Arctic Ice Loss. Here's a story, video and links to research from ThinkProgress; an excerpt:
Weather extremes in the summer — such as the record heat wave in the United States that hit corn farmers and worsened wildfires in 2012 — have reached an exceptional number in the last ten years. Man-made global warming can explain a gradual increase in periods of severe heat, but the observed change in the magnitude and duration of some events is not so easily explained. It has been linked to a recently discovered mechanism: the trapping of giant waves in the atmosphere. A new data analysis now shows that such wave-trapping events are indeed on the rise.
A number of studies in recent years have linked this quantum jump in extreme weather to global warming and the warming-driven loss of Arctic ice (see here and here). Jennifer Francis of Rutgers University’s Institute of Marine and Coastal Sciences has been at the forefront of this research. She explains her findings in this video..."
Greenland's Late August Rain Over Melt Ponds Is A Glacial Outburst Flood Hazard. Robert Scribbler has an interesting post; here's an excerpt: "Glacial melt ponding on steep ice faces. Above freezing temperatures for an extended period. Storms delivering rainfall to the glacier surface. These three events are a bad combination and one that, until recently, we’ve never seen before for Greenland. It is a set of circumstances directly arising from a human-driven warming of the great ice sheet. And it is one that risks a highly violent and energetic event in which melt ponds over-top and glaciers are flushed and ripped apart by surges of water rushing for scores of miles over and through the ice sheet..."

Climate Change Scientists Call On Colleagues To Speak Up On Global Warming Debate. Here's a video and excerpt of a story at The Sydney Morning Herald: "...One of Australia’s most senior climate scientists has called on his colleagues not to sit on the sidelines of the political debate about global warming and other environmental issues, given the evidence they present asks society to consider fundamental changes. In a speech to be given to the Australian Academy of Science on Tuesday evening, Dr Michael Raupach will say environment scientists' position in the public debate had changed because they were now presenting evidence requiring society to make major choices in response..."
Meet The Climate Deniers Who Want to be President. What has happened to the Republican Party? You can't be pro-free markets and strong on defense, and still acknowledge basic science, at least when it comes to climate change? At some point I hope cooler (smarter) heads prevail. Younger voters are taking this subject very seriously and will vote accordingly. Here's an excerpt from a story by Ben Adler at Grist: "...The Republicans basically fall into four categories: (1) Flat-Earthers, who deny the existence of manmade climate change; (2) Born-Again Flat-Earthers, who do the same, but who had admitted climate change exists back before President Obama took office; (3) Do-Nothings, who sort of admit the reality of climate change but oppose actually taking any steps to prevent it; and (4) Dodgers, who have avoided saying whether they believe climate change is happening, and who also don’t want to take any steps to alleviate it. Louisiana Gov. Bobby Jindal and Wisconsin Gov. Scott Walker fall into the latter category. The Do-Nothings are blue and purple state governors, Chris Christie of New Jersey and John Kasich of Ohio..."
Late-Night TV's Top 5 Moments in Denial-Busting.

Check out the top five moments in climate denial busting below — and share widely!"
It's a logical, reasonable question. "Paul, will it rain on my yard this evening?" We respond with probabilities and words like "isolated" and "scattered" thundershowers.
"You have Turbo-Doppler! Why can't you tell me if the storms will hit MY HOUSE?"
Welcome to the world of random weather. We can tell when conditions are ripe for storms, but will your neighborhood be the 10 to 20 percent of the state that sees rain?
In spite of 3 KM resolution models that update every hour the state of the art still can't answer that question with a high degree of confidence. A line of storms? That's straightforward. But hit-or-miss, "popcorn" instability showers? Good luck. Radar on a phone is probably your best tool for pinpointing rain chances for your GPS location. Anything else is an exercise in hand-waving.
Today looks quiet: no pulsating red blobs on Doppler. Storms rumble in Thursday with high humidity. Friday will be the better day to graze the healthy food choices at the State Fair, with highs near 90F. I'll be at the Star Tribune booth around midday to hang out with Vineeta Sawkar and babble about the dew point.
Near 90F Sunday, then a breath of fresh, September air next week.

Future Radar. Here is 60-hour NOAA NAM guidance showing the next wave of warm frontal thunderstorms pushing across southern and central Minnesota late tonight into Thursday morning. A counterclockwise swirl of showers pushes across the Great Lakes, with a possible severe storm outbreak pushing thru the Ohio Valley into the Mid Atlantic states. Monsoon-related T-storms flare up over the Rockies, but no colorful blobs appear over California, where the drought continues to deepen. Loop: HAMweather.
Accumulated Rainfall Potential. NOAA high-res models print out as much as 2-3" rain for the Twin Cities metro by Thursday night as a (hot) front surges north. If skies clear fast enough behind these storms the mercury may hit 90F on Thursday with dew points sweltering close to 70F. The maps look more like late June than late August into Sunday, but much cooler air knocks the mercury into the 60s and 70s much of next week with half as much water vapor in the air by Monday. If you're looking for comfortable weather for the Minnesota State Fair you may want to wait until next week. Guidance: HAMweather.com
El Nino: Fizzle or Sizzle? What happened to the much-anticipated, much-hyped El Nino event of 2014? It's still coming, according to NOAA's climate.gov. Here's an excerpt of a good post and update: "...In summary, we continue to favor the emergence of El Niño in the coming months, with the peak chance of emergence around 65% (i.e. there is a 35% chance of El Niño not occurring). ENSO forecasters do not expect a strong El Niño (we can’t eliminate the chance of one either), but we are not expecting El Niño to “fizzle.” In fact, just in the last week, we have started to see westerly wind anomalies pick up near the Date Line. Literally and figuratively, we may be witnessing the start of ENSO’s second wind."

If hot thermometers actually exploded like they do in cartoons, there would be a lot of mercury to clean up in California right now. The California heat this year is like nothing ever seen, with records that go back to 1895. The chart below shows average year-to-date temperatures in the state from January through July for each year. The orange line shows the trend rising 0.2 degrees Fahrenheit per decade. The sharp spike on the far right of the chart is the unbearable heat of 2014. That’s not just a new record; it’s a chart-busting 1.4 degrees higher than the previous record.

"Severe" Drought Covers Nearly 99.8% of California, Report Says. Here's an excerpt of a Los Angeles Times story, which includes an amazing infographic that shows the evolution of California's drought: "Drought conditions may have leveled off across California, but nearly 100% of the state remains in the third-harshest category for dryness, according to the latest measurements. For the past two weeks, California's drought picture has remained the same, halting a steady march toward worse. But the breather has allowed the state to recover only ever so slightly..."
British Columbia Has Spent More Than 3 Times Its Wildfire Fighting Budget. News1130 in Vancouver has the story; here's the intro: "The province is paying a pretty penny when it comes to fighting forest fires this summer. Around $200 million has been spent in the last few months, blowing past the original budget of around $60 million. And since the season is not over yet, that number is expected to grow. Kevin Skrepnek with the Wildfire Management Branch says when it comes to the size and severity of fires, this year has been the worst we have seen since 2010..."

Cheap Hurricane Hype? Is it just noise - or a signal for something we need to keep an eye on? A tropical wave east of the Lesser Antilles has a 50% probability of strengthening into a tropical system within 5 days, according to NOAA NHC. The forecast for midday Wednesday, August 27, one week from today, shows a tropical storm or hurricane in the Gulf of Mexico on the GFS, but the ECMWF (European) model isn't buying it, not yet. If you live along the Gulf Coast you might want to keep an eye on this. I tend to favor the ECMWF, especially with tropical development, but it would be unwise to ignore the GFS altogether. GFS model: Weather Bell; ECMWF guidance: WSI.
Summer of Research to Improve Hurricane Forecasting. In addition to flying into hurricanes (the USA is still the only nation on Earth that does this on a routine basis) NOAA is using two Global Hawk drones to go where no aircraft can go, providing additional data streams that may help forecasters, especially with intensity. Here's an excerpt from NOAA: "...Such targeted observations help significantly improve forecast models for predicting hurricanes, especially when the data can be gathered on a nearly continuous basis for an extended period in areas not now being observed. This fall, NOAA will join with NASA to launch two 115-foot wingspan Global Hawks. These unmanned aircraft will take off from Wallops Island, Va., on several data-collecting missions during five weeks at the height of Atlantic hurricane season. “With the Global Hawk we can fly farther out over the ocean and get to storms that manned aircraft cannot reach..."

Danger: Shifting Tracks. Data shows that hurricanes are reaching peak intensity consistently farther north, another symptom of a warming atmosphere and shifting weather patterns. Here's a clip from MIT Technology Review: "Powerful, destructive tropical cyclones are reaching their peak intensity farther from the equator and closer to the poles, according to a study coauthored by an MIT scientist. The study, published in Nature, shows that over the last 30 years, tropical cyclones—also known as hurricanes or typhoons—have been moving poleward at a rate of about 33 miles per decade in the Northern Hemisphere and 38 miles per decade in the Southern Hemisphere..."

Airborne Phased Array Radar Could Spur a "Quantum Leap" in Hurricane Forecasts. Meteorologists do a good job with track, but predicting intensity changes is more problematic. Will a next-generation doppler system help? Here's an excerpt of a story at The Capital Weather Gang: "Forecasts for the tracks of hurricanes have made huge strides over the past 15 years, improving by over 50 percent. But forecasts for the intensity of hurricanes have lagged, with only modest gains in accuracy seen very recently. A new technology under development at the National Center for Atmospheric Research (NCAR), known as Airborne Phased Array Radar (APAR), could be a game-changer for improving forecasts for hurricane intensity and other types of severe weather, according to those familiar with the project..."

Hurricane Camille: What If It Struck New Jersey? As waters continue to warm could more intense hurricanes systematically find their way farther north, threatening larger population center of the Northeast? The idea isn't as far-fetched as it sounds. Here are a few excerpts from an article at Asbury Park Press: "...Camille's surge was about 25 feet high while Sandy's storm tide (storm surge and astronomical tide) was roughly 14 feet at Sandy Hook, according to NOAA. Moreover, Camille's estimated peak winds were more than twice as strong as Sandy's....Experts have told me over the years that a Category 4 storm is the strongest hurricane that could threaten New Jersey because ocean waters aren't as warm off our coast as they are down south. Still, the storm surge from a Category 4 storm would move up to several miles inland in parts of Monmouth and Ocean Counties, according to maps on the New Jersey Office of Emergency Management website..."

Tornado-Proof Shelter for Holdrege Students. Here's an elementary school in Nebraska that is taking the lead in protecting students and staff, an excerpt of an interesting story at KHGI-TV: "...Safety is what parents want and demand when leaving their kids in the hands of teachers. Now those in Holdrege can breathe a sigh of relief as a new storm shelter can withstand 250 mile per hour winds is being built. Todd Hilyard, the superintendent for Holdrege Public Schools looked over the latest plans for the new elementary school. "All of this, both the exterior walls as well as the interior, are masonry block walls with rebar and concrete fill as well as a concrete roof on top of the storm shelter," he said. "I think every superintendent's heart is in the right place and unfortunately these are expensive areas to build..."
Secrets of Iceberg That Sank The Titanic Revealed In New Study. It turns out 1912 may not have been much of an above-average year for big icebergs. Then again, all it takes is one. Here's an excerpt from a story at Huffington Post: "...Aside from reshaping long-held theories about the Titanic tragedy, the new findings -- described in a paper published online in July 2014 edition of the journal Significance -- may hold an important warning for seagoing vessels today. “As use of the Arctic, in particular, increases in the future, with declining summer sea ice the ice hazard will increase in waters not previously used for shipping," the researchers conclude in the paper. "As polar ice sheets are increasingly losing mass as well, iceberg discharge is increasing... and increasing global warming will likely cause this trend to continue."
In Silicon Valley, Mergers Must Meet The Toothbrush Test. I like the sound of this - pay for things you use every day. Here's an excerpt of an interesting article at The New York Times: "When deciding whether Google should spend millions or even billions of dollars in acquiring a new company, its chief executive, Larry Page, asks whether the acquisition passes the toothbrush test: Is it something you will use once or twice a day, and does it make your life better? The esoteric criterion shuns traditional measures of valuing a company like earnings, discounted cash flow or even sales. Instead, Mr. Page is looking for usefulness above profitability, and long-term potential over near-term financial gain..."

How The World's Biggest PR Firm Helps Promote Climate Change Denial. Here's the intro to an eye-opening story at Motherboard. What a shock, it's all about the money: "When a recent Guardian survey asked top public relations firms if they would refuse to represent organizations that denied climate change, the response was encouraging: ten of the largest said they would. Decidedly less inspiring was the response of the world's single biggest PR company, Edelman, which said it would not rule out helping corporations spread messages of climate change denial. This shouldn't be too surprising, seeing as how it's already doing precisely that. A lot. Edelman helps polluting companies use TV ads, astroturf groups, and slick websites to promote climate change denial around the globe..."

Did Global Warming Cause "The Great Flood of 2014?" Detroit meteorologist (and friend) Paul Gross provides a thoughtful, scientifically accurate answer to that question at clickondetroit.com; here's an excerpt: "People have been asking me if last week’s historic flood was caused by global warming. The short answer is NO, but read on because this answer requires an explanation. Weather systems develop all the time, and have been doing so for as long as we’ve had weather on this planet. The weather system that developed and dumped a once-every-500-year rain event on metro Detroit last week may have developed anyway. HOWEVER, our warming climate might have made that weather system a heavier rain-producer than it might have been..."
Snow Has Thinned on Arctic Sea Ice. Here are some of the latest findings from The American Geophysical Union: "Scientists have been tracking snow depth on Arctic sea ice for almost a century, using research stations on drifting ice floes and today’s radar-equipped aircraft. Now that people are more concerned than ever about what is happening at the poles, a new study confirms that snow has thinned significantly in the Arctic, particularly on sea ice in western waters near Alaska. The new assessment, accepted for publication in the Journal of Geophysical Research: Oceans, a publication of the American Geophysical Union, combines data collected by ice buoys and NASA aircraft with historic data from ice floes staffed by Soviet scientists from the late 1950s through the early 1990s to track changes over decades..."

Antarctica Could Raise Sea Level Faster Than Previously Thought. Here's a clip from a story at redorbit.com that caught my eye: "Ice discharge from Antarctica could contribute up to 37 centimeters to the global sea level rise within this century, a new study shows. For the first time, an international team of scientists provide a comprehensive estimate on the full range of Antarctica’s potential contribution to global sea level rise based on physical computer simulations. Led by the Potsdam Institute for Climate Impact Research, the study combines a whole set of state-of-the-art climate models and observational data with various ice models. The results reproduce Antarctica’s recent contribution to sea level rise as observed by satellites in the last two decades and show that the ice continent could become the largest contributor to sea level rise much sooner than previously thought..."

Meet The Companies That Are Trying To Profit From Global Warming. As I've said (ad nauseum) climate change and climate/water volatility represents a threat, and an opportunity. Many, even most of the solutions will come from the private sector. Here's an excerpt of a story at Vox: "...Greenland has taken advantage of the warming Arctic — which is melting the ice and opening new mining opportunities — to push for independence from Denmark. The government is already anticipating millions of dollars in new tax revenue as oil and gas rush north. Alcoa even has plans for a massive aluminum smelter there — powered by Greenland's rivers of melting ice. Dutch engineers are selling their storied flood-management expertise to countries threatened by sea-level rise. One company, Dutch Docklands, is pitching visions of floating cities to regions that could eventually find themselves underwater..."

where the excess heat is primarily going — the ocean — and the rate at which heat transfers to the deep ocean, as well as other factors that can temporarily offset the influence of heat-trapping gases..."Even as a car slows down to go over a “speed bump,” there is no question the car is still advancing down the road. Similarly, the global average surface temperature trend of late is like a “speed bump” and we would expect the rate of temperature increase to speed up again just as most drivers do after clearing the speed bump. We keep getting questions about this air temperature trend that has more to do with
What I Learned From Debating Science With Trolls. Here's an excerpt of a post at The Conversation, one of many tactics used by denialists; this one focused on perverting Galileo's legacy: "...The Galileo Gambit is a debating technique that perverts this history to defend nonsense. Criticisms by the vast majority of scientists are equated with the opinions of 17th century clergy, while a minority promoting pseudoscience are equated with Galileo. Ironically, the Galileo Gambit is often employed by those who have no scientific expertise and strong ideological reasons for attacking science. And its use isn’t restricted to online debates..."

Hint of Dog Days
"Ah, summer, what power you have to make us suffer and like it" said Russell Baker. Except for a Bangladesh-like June and a few severe wind episodes there hasn't been all that much suffering this summer.
I still don't see anything resembling an old-fashioned heat wave but, with high confidence, I can predict that neighbors and complete strangers will be griping about drippy dew points within a few days - forecast to hold near 70F from Saturday into most of next week.
That's one of the trends we're tracking: summers aren't appreciably hotter on average in Minnesota (the real warming signal is showing up in winter, especially at night), but dew points are running consistently higher. Warmer air can hold more water vapor, meaning higher humidity levels; more moisture available to spark extreme rain events.
The heaviest T-storms should track south of Minnesota into the weekend; a relatively dry spell with temperatures in the 80s - even a shot at 90F next week. More like mid-July.
In today's weather blog: America's low-orbiting weather satellites may be in trouble. And new research confirms an uptick in extreme weather; odd jet stream gyrations that cause the weather to become "stuck".
A Minor Case of the Dog Days. Soak up the low dew points, because it'll feel like early July again by late week, with tropical air lingering into next week. Highs will reach the mid-80s, and I could see a 90F or two next week. The arrival of this steamy warm front sets off isolated T-showers Friday into Sunday, a better chance of T-storms by the middle of next week.
Super Soakers Push Across New England. The same front that flooded much of Detroit and Baltimore will push heavy T-storms across New England today, enough rain for flash flooding in some communities. Monsoonal T-storms pop up from near Phoenix to Salt Lake City, a few random storms flaring up over the Pacific Northwest. 60-hour WRF Future Radar courtesy of NOAA and HAMweather.
More Like June. By August the atmosphere should be stabilizing with fewer thunderstorms capable of severe weather and flash flooding. Tell that to residents of the Northeast, where some 2-5" rains are possible again today. Dry weather dominates over the central USA, locally heavy rain over the Rockies from late afternoon instabilty T-storms. 60-hour WRF rainfall totals: NOAA and HAMweather.
"Unprecedented" Flooding Event in Detroit Fits Global Warming Pattern. Meteorologist Andrew Freedman has the story at Mashable; here's an excerpt that caught my eye: "...Paul Gross, chief meteorologist for WDIV-TV in Detroit, that the event was absolutely unprecedented in his long career in the city.
I have lived my entire life and worked my entire career here, and I have never seen as widespread a flooding event. Yes, I vividly remember the May 2004 historic month of rain — our second wettest month ever with 8.46 inches of rain — but that was a bunch of rainy days that really added up.
I also remember some individual intense thunderstorms that flooded ONE freeway. But I don't ever remember EVERY freeway being flooded out.
The storm, which is likely to have caused tens of millions in damage to a city that is already struggling economically, is an example of the type of event that is already occurring more frequently and severely due to manmade global warming..."

Extreme Weather Becoming More Common, Study Says. Details of the new paper are below (in the climate story section), but it shows the possible link between large-scale, long-term climate shifts and day to day weather. So far there is correlation, but no causation, no final smoking gun proving the link. Here's an excerpt from The Guardian: "..Climate scientists in Germany noticed that since 2000 there have been an “exceptional number of summer weather extremes, some causing massive damage to society”. So they examined the huge meanders in the high-level jet stream winds that dominate the weather at mid-latitudes, by analysing 35 years of wind data amassed from satellites, ships, weather stations and meteorological balloons. They found that blocking patterns, which occur when these meanders slow down, have happened far more frequently. “Since 2000, we have seen a cluster of these events. When these high-altitude waves become quasi-stationary, then we see more extreme weather at the surface,” said Dr Dim Coumou, at the Potsdam Institute for Climate Impact Research. “It is especially noticeable for heat extremes...”
Extreme Summer Heat, Rain On Rise As Weather Gets Trapped - Study. Picking up on the new research released Monday here's a slightly different perspective from Reuters: "...We are warming our atmosphere by emitting carbon dioxide from fossil fuels, but the increase in devastating heatwaves in regions like Europe or the U.S. seems disproportionate," lead author Dim Coumou said in a statement. Climate change was disrupting the flow of the jet stream, which blows from west to east around the Earth and forms waves high in the atmosphere that can be thousands of km (miles) from crest to crest. "In periods with extreme weather, some of these waves become virtually stalled and greatly amplified," it said. "While a few days have little impact, effects on people and ecosystems can be severe when these periods are prolonged..."
California Drought: San Francisco Poised To Require Water Rationing.

Sweden's Massive Forest Fire Lit By Record Temperatures. Nature World News has more details on the highly unusual wildfire impacting Sweden; here's a clip: "...As of August 7, the fire was deemed a national emergency, and the Swedish Armed Forces was mobilized to aid firefighters and help facilitate an orderly evacuation of affected and threatened areas. A fire of this size is extremely uncommon in Sweden, which traditionally experiences fores fires that encompass a few square miles at most, according to the International Forest Fire News. In fact, fires are so rare in the region that the Swedish movement actually prescribes controlled burning of old and dried brush to promote healthier woods..."

The Legacy of Florida's Year of Four Hurricanes. The Orlando Sentinel has a good recap of a very crazy year: 2004. Here's a clip: "For six weeks, Florida reeled under the assault of four hurricanes. First Charley struck Port Charlotte Aug. 13, 2004, with 150-mph winds. It blasted its way into Central Florida five hours later with winds clocked at 105 mph at Orlando International Airport. Hurricane Frances followed on Sept. 5 with lashing winds and drenching rains that would total 14 inches in metro Orlando. Tree limbs tore down power lines. Roofs were peeled from homes. Thousands sweltered without electricity. Then Ivan came ashore near Pensacola with 120-mile-per-hour winds and a storm surge that swamped coastal towns. And Jeanne struck the same area as Frances on Sept. 25, adding insult to injury..."

America's Weather-Tracking Satellites Are In Trouble. It's the low-earth satellites that are triggering the greatest concern; here's an excerpt of a good overview from Popular Mechanics: "...Those polar-orbiting satellites, a primary and its backup, are the ones in crisis. The primary satellite—a short-term pathfinder built to test emerging technologies—was never really intended for use. Its backup isn't much better: an aging satellite with failing sensors that passed its predicted life expectancy last year. We would send up a replacement now, but it's still being built. When it is ready, should it survive launch, it could take until as late as 2018 to transmit usable data. Which means that, depending on when our current satellites stop working, the U.S. could be without crucial data for years. That's worse than inconvenient. It could cost us trillions of dollars, and hundreds, if not thousands, of lives..."

Can Weather Patterns Help Predict Disease Outbreaks? Here's an excerpt of an interesting story and video at CNN: "Scientists and meteorologists are able to predict the weather - could they apply the same technology to predicting epidemics like Ebola? Carlos Watson, co-founder and editor of OZY, appeared on "New Day" Friday to discuss the efficacy of climate change data and technology, and how it could prevent future outbreaks. Researchers have found that there could be correlations between weather patterns and the development of disease in a specific region..."
U.S. Capability To Respond To The Next Great Disaster. As populations continue to grow, with more people living in (vulnerable) regions near rivers and sea level, the potential for major disasters continues to increase. Here's a story from a story pondering hypotheticals at The Brookings Institution: "..But as global populations grow, especially along the Asian littoral, and as certain storms or large-scale weather patterns are perhaps intensified or at least shifted by climate change we need to be ready for worse. Superimposing the bands of devastation from some of the above on more populated areas helps one see the realm of the plausible. What if the Fukushima nuclear accident had affected reactors near Tokyo, with its population of some 30 million? What if a future Typhoon Haiyan targets Shanghai? What if a massive earthquake hit Karachi, Pakistan or sent a tsunami into the heavily populated areas of coastal East Asia?..."

Is Sunscreen a Lifesaver or a Poison? Or does it lull us into receiving far more sunshine than we really should? Everything in moderation, right? Here's an excerpt of an interesting story that had me running for shade at FiveThirtyEight: "... People who are fair-skinned have higher skin cancer rates, and their pigmentation matters more than where they live. What is less well established, at least in the data, is whether sunscreen mitigates these risks. The theory behind sunscreen is very sound. Sunscreen absorbs UV light, blocking it from reaching the skin, and UV light exposure is linked with cancer. In practice, however, the evidence on the relationship between sunscreen use and skin cancer is more limited..."
How Weather and Climate Models Work - Or Why Meteorologists Learn Calculus. Yes, I still have nightmares about Math 102, "Advanced Partial Differential Equations". Nasty stuff (and I still can't balance my checkbook). Here's an excerpt of a good explainer from Dan Satterfield at AGU, The American Geophysical Union: "Numerical weather models have come light years over the last 30 years, and despite what you may think, they make it possible to make very accurate weather forecasts for as much as 5-7 days into the future possible. Have you ever wondered just how they work? It’s not something that you can cover in a few paragraphs, but it is not all that hard to get a basic understanding of how it’s done, and if you will give yourself 50 minutes and pay attention, you will (I hope) find it very fascinating. You will also not just see greek when you see an equation like this somewhere!..."
How To Cover The Robin Williams Story Responsibly. Borrow a term and concept from physicians, the Hippocratic Oath: "...but first, do no harm". I thought Al Tompkins brought up some very good points in a recent article at Poynter - here's an excerpt that caught my eye: "...One of the most common mistakes that journalists can make in covering suicide is to advance the notion that one big thing caused someone to take their life. Suicide is a complex response that usually involves lots of factors including mental illness. In fact, suicide experts estimate 90 percent of suicides have some connection to mental illness and/or substance abuse. Both are treatable..."
"...The truth is that depression has nothing to do with bravery or courage. It is a monster that strips those traits away before it even gets warmed up. If anything, Robin Williams' suicide is another reminder that all the talent and humor in the world is no match for the power and darkness of depression. The way I see it, if you can fight off depression for 63 years and make others laugh and feel good, you are one courageous dude...." - Dave Pell, author of NextDraft.
Dealing With Depression. On Monday SAVE (suicide awareness - voices of education) had it's annual golf tournament at the TPC Course in Blaine. Many of the golfers and sponsors have had first-hand experience with the ravages of suicide, and were there to support prevention efforts, finding new ways to get a critical message out: mental health issues tend to be ignored until it's too late. There are treatments and medications that can help people struggling with depression. News of Robin Williams taking his life struck like a thunderbolt, and it highlighted the reality: it doesn't matter if you're rich or poor, famous or infamous - depression can strike anyone. It's up to us to search for symptoms, be aware, and get the people we care about the help they need - in time. Here's more from SAVE, based on Bloomington, with an international outreach:
"SAVE is saddened to hear about the passing of Actor Robin Williams and expresses our condolences to his family and friends. At SAVE we know well the tragedy of suicide and the impact it has on everyone. It you would like to know more about how to prevent suicide, we have information on the warning signs and what you can do to help someone. If you are struggling with thoughts of suicide or harming yourself, please call us (7283) or you can reach out to the National Suicide Prevention Lifeline at (8255) 24 hours a day / 7 days a week..."
* more Americans now die of suicide than car accidents, according to the CDC and New York Times.
"...I’ve said it before, and I’ll say it again; dismissing the concerns of a genuine depression sufferer on the grounds that you’ve been miserable and got over it is like dismissing the issues faced by someone who’s had to have their arm amputated because you once had a paper cut and it didn’t bother you. Depression is a genuine debilitating condition, and being in “a bit of a funk” isn’t..." - Dean Burnett at The Guardian.
Hit The Reset Button On Your Brain. Our businesses and friendships often require that we stay connected to The Matrix, but our long-term mental health requires that we disconnect and give our brains a break; so argues an important story and study highlighted at The New York Times; here's a clip: "...Every status update you read on Facebook, every tweet or text message you get from a friend, is competing for resources in your brain with important things like whether to put your savings in stocks or bonds, where you left your passport or how best to reconcile with a close friend you just had an argument with. If you want to be more productive and creative, and to have more energy, the science dictates that you should partition your day into project periods. Your social networking should be done during a designated time, not as constant interruptions to your day..."
Electric-Drive Paddleboard for Anglers? Gizmag had an article about some pretty cool retrofits for a paddleboard if you're looking for new (quiet) ways to get that trophy lunker; here's a clip: "Always looking for a new excuse to run its electric jet drive through the water, WaveJet has released a new board designed for fishing. The Pau Hana Big EZ Angler is the jet-powered stand-up paddleboard that provides stand-up fishermen with a new way to quietly troll the local fishing hole..."

Arctic Methane Could Accelerate Climate Change. Unknown unknowns. We like to think, as a species, that we know all the various paths the future might take, but when it comes to climate and potential tipping points...we don't know nearly as much as we think we know. Here's a clip from The Green Optimist: "...Unfortunately, climate change due to rising CO2 levels is generating a spiral effect, a positive feedback loop, which could lead us to a dangerous situation. Dr. Box colorfully notes that, if even a fraction of Arctic carbon is released, we’re “f-bombed as a species.” The problem is that warmer temperatures are increasing the temperatures of ocean currents, as well as air currents, which is leading to melting ice caps, permafrost, and the undesirable effects that these generate in their own turn. For example, some theorize that the recent hole that opened up in the Yamal Peninsula, Northern Russia, could actually have been caused by a collapsed pingo, that is, melted permafrost leaving a cavity, which caved in. It may also have been accompanied by a release of natural gas, which is commonly found in the area..."
Tom Skilling on Climate Change. Chicago Tonight at WTTW-TV has an interview with one of the best TV meteorologists on the planet, Tom Skilling (and a great guy too). Here's an excerpt: "...You know, I’m often asked why scientists only focus on the negative aspects? If you look at both human society and ecosystems, they’ve both adapted to changes in the climate when the changes are little. The changes we’re seeing now are occurring 10 times faster. A rapid change makes it difficult for both ecosystems and human societies to adapt to it..."
Ebola and Climate Change: Are Humans Responsible for the Severity of the Current Outbreak? Alarmist hype? Maybe. Newsweek has the story that attempts to connect the dots; here's a clip: "...Humans are the major driver of emerging diseases,” says Jonathan Epstein, an epidemiologist at the non-profit EcoHealth Alliance who studies Ebola and other infectious disease. “Things like agricultural expansion and deforestation...and certainly travel and trade — these are things that manipulate our environment and allow pathogens to get from animal hosts to people and then travel around the world.” In a study published in 2012, researchers asked national infectious disease experts in 30 different countries whether or not they thought climate change would affect infectious disease patterns in their countries. The majority agreed..."
Don't Believe The Hype. 5 Reasons To Be Pessimistic About Climate Change. I have my moments of pessimism - can we, as a global society, really get our arms around this problem in time, in a concerted, thoughtful way that won't wreck the economy? This will be our Moon Shot and Manhattan Project rolled into one for the 21st century. Here's an excerpt of a more downbeat assessment at The Week: "...While the EPA's new regulations on power plants are a welcome first step, they are not carved in stone. The EPA will likely face numerous legal and legislative challenges before its rules are implemented. Meanwhile, climate change denial remains the mainstay of a significant portion of one half of the American political spectrum. Messaging aimed at muddying the waters — of both the science of climate change and the political imperative in tackling it — has not abated. As Slate's Will Oremus has reported, deniers are now willing to acknowledge some aspects of the scientific reality, but are quick to interject that the cure will be worse than the disease..."

Quasi-Resonant Circulation Regimes and Hemispheric Synchronization of Extreme Weather in Boreal Summer. It's a long title for a fairly straightforward concept, a symptom of rapid warming, especially at northern latitudes, which may be impacting the wavelength of global Rossby waves, creating conditions more favorable for an elongated (high amplitude) jet stream, one more prone to extreme weather, severe heat and excessive rains. For several years I've been wondering if it was my imagination, if we really were seeing tangible evidence of a more amplified jet stream capable of more frequent weather extremes over the Northern Hemisphere? Or was there hard data - research, to back up these observations? Here's a summary of a technical, but very important new paper from Coumou, Petoukhov, Rahmstorf, Petri and Schellnhuber at PNAS.org: "...The recent decade has seen an exceptional number of boreal summer weather extremes, some causing massive damage to society. There is strong scientific debate about the underlying causes of these events. We show that high-amplitude, quasi-stationary Rossby waves, associated with resonance circulation regimes, lead to persistent surface weather conditions and therefore to midlatitude synchronization of extreme heat and reainfall events. Since the onset of rapid Arctic amplification around 2000, a cluster of resonance circulation regimes is observed involving wave numbers 7 and 8. This has resulted in a statisticially significant increase in the frequency of high-amplitude quasi-stationary waves with these wave numbers. Our findings provide important insights regarding the link between Arctic changes and midlatitude extremes..."
Slow Summer Fade
The reptilian, attracted-to-shiny-objects part of my brain doesn't want summer to end. I look forward to changing into my scruffy after-work uniform of shorts, t-shirt & flip flops.
But I also realize that a full, stomach-churning cycle of the seasons is required for replenishment and renewal of nature. Minnesota wouldn't be home to Great White Pines, walleye navigating crystal-clear lakes or bumper crop harvests without a reliable annual winter smack.
Even so, Back To School sales, State Fair jingles & football on the tube all leave me feeling nostalgic; like coming to the end of a great novel you never want to put down.
Vonnegut said it best. "And so it goes".
Heavy T-storms slosh across southwest Minnesota into Thursday, but the metro area on up to the Brainerd Lakes may stay dry into Saturday. Highs push into the low 80s with sticky dew points - warm enough for the lake or that favorite adult beverage out on the deck.
T-storms push in Sunday - a slight cooling trend by late next week.
Both Iselle and Julio should reach Hawaii as tropical storms later this week; a wet 1-2 punch. The remains of Bertha may break a heat wave in the U.K.
Oh, only 141 days until Christmas!
Close Encounter of the Soggy Kind. Heavy showers and T-storms capable of 2-3"+ rains will track fro South Dakota into Iowa, brushing southwestern Minnesota with a potential for flash flooding today and tonight. Additional flash flooding is possible over Missouri Thursday into Friday; potentially severe T-storms from near Lake Tahoe to the Wasatch Range. 4 KM WRF Accumulated Rainfall: NOAA and HAMweather.
Sign of the Times. We've lost about 1 hour of daylight; nights are longer - giving the temperature more time to reach the dew point, sparking lazy clouds: fog. On the high-res 1 KM visible loop you can see stratus clouds and fog over southwest Wisconsin and southeastern Minnesota warming up in response to surface heating. Loop: HAMweather.
Double Trouble for Hawaii: Iselle and Julio. Discover Magazine has more information on the tropical systems pushing toward Hawaii later this week, forecast to arrive as tropical storms; here's a clip: "Heads up Hawaii: Double trouble is headed your way in the form of two tropical cyclones. The image above, acquired Monday (Aug. 4) by NASA’s Terra satellite, shows the situation: Hurricane Iselle to the left, and Tropical Storm Julio to the right. Both are expected to affect the Hawaiian Islands in the coming week..."
To Save Lives, Scientists Probe the Secrets of Towering Wildfire Clouds. Also known as "pyrocumulus"; Mashable has a fascinating article with some remarkable photos; here's an excerpt: "...As of Tuesday, about 490,000 acres were burning across the U.S., with 12 large fires burning in California, 11 in Oregon and four in Washington, according to the National Fire Information Center in Boise, Idaho. Some of these fires have launched plumes of smoke up into the jet stream, where it has been carried eastward, obscuring the sky across Minnesota and Wisconsin. The clouds associated with these fires can resemble volcanic eruptions and sometimes they even generate their own lightning and thunder, in which case they are renamed “pyrocumulonimbus.” (Pyro is the Latin word meaning “fire.”)..."

An "Extreme Weather" Bill? H.R. 5314 — the Preparedness and Risk Management for Extreme Weather Patterns Assuring Resilience Act of 2014, is a bi-partison effort to better prepare the United States for extreme weather events. Here's an excerpt from Republican Herald: "...Since 1980, the U.S. has experienced 151 weather-related disasters costing more than $1 billion each, with cumulative costs more than $1 trillion, the bill states. The federal government spent $100 billion in 2012 alone dealing with droughts, storms, floods and forest fires. “The changes that I’m proposing should help the government save billions of dollars in the long-run,” Cartwright said. The bill references a 2013 report by the Government Accountability Office stating federal efforts to prepare for extreme weather events are uncoordinated, including its cooperation with tribal, state and local governments..."
Pentagon Weather Satellites Raise Hacking Vulnerability, Watchdog Finds. Roll Call has the intriguing and worrying details; here's a snippet: "No one has ever done a security assessment of a Defense Department weather satellite program used by the Pentagon to monitor potential battlefield conditions, according to an inspector general report. There might not even ever be a security assessment to make sure it meets DOD’s standards, in fact. And because that system is interwoven with another program by the National Oceanographic and Atmospheric Administration, it makes that one more vulnerable to hacking..."
The Is The Equation for Happiness. Who knew you could come up with math to predict your state of happiness? Time Magazine has more details: "...The researchers were not surprised by how much rewards influenced happiness, but they were surprised by how much expectations could. The researchers say their findings do support the theory that if you have low expectations, you can never be disappointed, but they also found that the positive expectations you have for something—like going to your favorite restaurant with a friend—is a large part of what develops your happiness..."

At What Age Are We The Most Popular We'll Ever Be? Assuming we were ever popular in the first place? I would get 6 months old, diapers, cute smile. But new data suggests the magic age for maximum number of friends may be closer to 29. First: define what a friend really is. Do Facebook "friends" count? The Independent has more details; here's an excerpt: "...The reason for this is because we apparently share the strains of working in high-pressured environments and spend more hours in the office than ever before. The data also found that those working in marketing have the most friends at work, just ahead of chefs, servicemen and women, artists and designers, and finally those in HR..."

The Greatest Documentaries of All Time. That's a tall order, but the British Film Institute has a pretty good start on this project; here's a clip: "What are the greatest documentaries ever made? We polled 340 critics, programmers and filmmakers in the search for authoritative answers. Nick James introduces our poll while, below, we list the critics’ top 56 documentaries. Across the page, you can see the filmmakers’ top 35 films. Individual lists and comments from a sample 50 critics and 50 filmmakers can be found in our September 2014 issue, while full versions of all the entries will be posted online on 14 August..."

Climate Change May Increase The Number of Hawaiian Hurricanes. Dr. Jeff Masters at Weather Underground reviews recent research suggesting a 2-3X increase in hurricanes impacting the Hawaiian Island Chain by the end of the century as waters warm and patterns shift north; here's an excerpt: "...But with two hurricanes potentially threatening the islands in the coming week, and Tropical Storm Flossie having passed with 100 miles of the islands in 2013, it is fair to ask, could climate change be increasing the odds of tropical storms and hurricanes affecting the Hawaiian Islands? A 2013 modeling study published in Nature Climate Change, "Projected increase in tropical cyclones near Hawaii", found that global warming is expected to increase the incidence of tropical storms and hurricanes in Hawaii..."
This is Climate Change: Ohio's Water Crisis was a Man-Made Disaster. It's a combination of factors: heavier summer rains sparking more run-off, coupled with warming water on the Great Lakes. Here's a clip from Salon: "...Welcome to life — weird, chaotic, scary, disruptive — in a changing climate. The direct cause of Ohio’s water problems, according to city officials, was likely an algae bloom in Lake Erie. The cause of the algae bloom? In a word: Us. The lake, the world’s largest freshwater system, has been increasingly overwhelmed by an influx of phosphorus: runoff from industrial agriculture and from urban sewage treatment plants. Meanwhile, summer has been becoming hotter and longer, conditions that promote the algae’s spread..."

Lake Erie Algae Bloom Matches Climate Change Projections. More details from Scientific American; here's an excerpt: "...It’s a combo of more rainfall; that climate change is predicted to cause more severe rain events. And more rainfall means more nutrients and higher nutrients mean more toxicity,” Timothy Davis, an ecologist at the Great Lakes Environmental Research Laboratory, said. An increase in heavy rainfall is already being seen throughout the U.S. The Midwest has seen a 37 percent increase in the amount of rain falling in heavy precipitation events since the late 1950s, the second-highest increase in the U.S. over that period..."

Climate Change Skeptics Rejected By PR Firms. Here's an excerpt of an interesting development from Headlines and Global News: "A handful of the world's top public relations companies declared they will not represent clients who say man-made climate change doesn't exist, The Guardian reported.
