June 11, 2011: Severe thunderstorms bring extremely strong wind to central Minnesota. An unofficial wind gust of 119 mph is reported at a seed farm 1 mile northwest of Atwater. A storm chaser’s car was battered when he got too close to the storm. Most of the windows in the car were broken.
June 11, 1996: 5.91 inches of rain fall at Mankato. Mudslides close roads, including Hwy. 169, and push a trailer home 20 feet down a hill.
June 11, 1922: A hailstorm at Maple Plain causes extensive damage to crops.
Breathing Easier Today But Extra-Soggy Next Week
Hey, if the weather didn’t change every once in a while we’d have nothing to talk about. Even for a jaded, semi-cynical weather observer yesterday was jaw-dropping, with a Heat Advisory, Smog Alert and a significant severe storm threat. Other than that it was a lovely Friday.
The immediate metro area dodged a stormy bullet with the most intense squall line pushing south and east of the Twin Cities, but there were reports of enough hail to damage cars and plants in Burnsville. When it gets that hot and humid with strong winds near the ground, an atmospheric toxic brew, be on the lookout for wild storms.
A wind shift to the northeast drops dew points into the low 60s today. In spite of low 90s it won’t feel as oppressively humid. Soak up a (rare) dry day because T-storms return on Sunday and long-range guidance hints at some 1 to 3 inch rainfall amounts next week. The ECMWF model shows a storm temporarily stalling over Minnesota by the middle of next week as temperatures cool.
With any luck we’ll be back into the 80s with sunshine next weekend. Yes, every weekend matters.
Friday Severe Storm Reports. The well-anticipated squall line literally blew up directly above the Twin Cities; reports of hail big enough to damage cars and plants in Burnsville, but the line intensified as it pushed across southern Minnesota and Wisconsin. I saw numerous reports of 1-2″ diameter hail; wind gusts as high as 75 mph at Cannon Falls. Map credit: Aeris Enterprise.
A More Tolerable Heat Index. Today will still border on hot, but dew points drop from low 70s into the low 60s, so it should feel better out there. Lot’s of sunshine, no pulsating red blobs on Doppler – today definitely the nicer day of the weekend for outdoor plans. Heat Index plot: Aeris Enterprise.
Cooling Trend Next Week. ECMWF guidance shows temperatures cooling off a bit next week; not buying 60s on Wednesday yet, but a storm forecast to temporarily stall over Minnesota by midweek should result in a few relatively cool days before we warm up again next weekend. Graphic: WeatherBell.
Quiet Saturday – Storms Return Sunday. I get to unplug the Doppler today; less checking radar on my phone – worrying about watches and warnings. A weak push of slightly drier air treats us to sunshine, with less humidity and a light northeast breeze. Soak it up, because 4 km NAM guidance brings bands of showers and T-storms back into Minnesota Sunday. Source: AerisWeather.
Another Wet Week? Models continue to suggest at least an inch or two of rain for many locations, coming in a few sloppy spurts: Sunday, again Wednesday and Thursday as a southern storm pinwheels right over Minnesota.
Heating Up Again Late June. At least that’s the impression looking at predicted 500 mb (GFS) winds roughly 2 weeks out, showing a bloated heat-pump high pressure ridge over the Rockies and Plains.
From Frost to Heat Advisories in Less Than One Week. Dr. Mark Seeley has details on the frost event that took place just 3-4 days ago up north in this week’s edition of Minnesota WeatherTalk; here’s a clip: “June 7 and 8 brought cold morning temperatures to many parts of the state, especially northeastern counties. Many climate observers reported morning lows in the 30s F, and several reported frost. A number of climate stations also reported new record daily low temperatures. These included:
June 7th 37F at Kabetogama and Littlefork
June 8th: 28F at Crane Lake; 29F at Hibbing and Orr; 30F at International Falls and Babbitt; and 37F at Sandstone.
Actually frosts this time of year are not all that unusual in northern Minnesota counties, with a 10 to 20 percent historical frequency during the 2nd week of June…”
Heat Soars to Record Levels Across West, Heads East. Here are a few interesting weather nuggets in a story at WXshift: “…Several spots in the West set new high temperature records last week. Phoenix is normally hot this time of year, with a normal high of 102°F (39°C), but there were four consecutive days (June 3-6) when the high was more than 110°F (43°C). Each of those four days brought a new record high, with the temperature peaking at 115°F (46°C) on June 4. Even traditionally cooler spots of the Pacific Northwest have been especially hot. According to the National Weather Service in Seattle, the average temperature for the first week in June this year has been the second hottest since the 1890s. Similarly, the high of 84°F (29°C) on June 7 marked the 14th day that was 80°F (26.7°C) or warmer this year. The record for the most days at or above 80°F by the end of June is 15, which was set just last year...”

Congress Is Considering Privatizing Key Roles of the Weather Service. That’s a Mistake. I agree, because the end result may be meteorological anarchy, conflicting warnings, confusion and loss of life. Here’s an excerpt of an Op-Ed at The Washington Post: “Imagine a future in which tornado warnings are not issued by a single entity, the National Weather Service, but rather by multiple private companies. These companies all have different methods and rationale for warnings, so they aren’t always being issued for the same storms and the same locations. In this future, warnings as we currently know them have disappeared. As a storm approaches your neighborhood, you might think you’re under a tornado warning, but your neighbors are not — you get your weather from different sources that happen to disagree on the severity of this storm. There’s a lot of confusion at an extremely dangerous moment...”
Europe to America: Your Love of Air Conditioning is Stupid. Here’s an excerpt from The Washington Post: “…Overall, it’s safe to say that Europe thinks America’s love of air-conditioning is actually quite daft. Europeans have wondered about this particular U.S. addiction for a while now: Back in 1992, Cambridge University Prof. Gwyn Prins called America’s love of air-conditioning the country’s “most pervasive and least-noticed epidemic,” according to the Economist. And according to the Environmental Protection Agency, it’s getting worse: American demand for air-conditioning has only increased over the past decades….”

I think we can start to connect these dots and say that increasing loss of Arctic sea ice is leading to more blocking patterns, which are contributing to the increasing surface melt on Greenland,” said Jennifer Francis, the Rutgers University Arctic expert whose ideas about Arctic melting distorting the jet stream have ignited one of the biggest ongoing debates in climate science, and who is familiar with the new study by Tedesco and his colleagues. “Of course, this is bad news for sea-level rise and maybe also for the ocean circulation as the extra meltwater appears to be partially responsible for the ‘Cool Blob’ south of Iceland...”

The Epic Volcano Eruption That Led to the “Year Without a Summer”. Jack Williams explains at The Capital Weather Gang; here’s an excerpt: “…The average temperature of the globe dropped a mere 3 degrees, but that small change proved dramatic for not only Earth’s climate but for life in the Northern Hemisphere. Some of the worst effects, including summer-time frost, impacted the eastern U.S. as far south as Virginia. In Europe and Great Britain the volcano’s effects included not only the coolest summer on record, but day after day of cloud-covered skies and above normal rainfall, which caused widespread crop failures, outbreaks of disease and famine…” (Volcano file image: mounttambora.com).
Air Pollution Now Major Contributor to Stroke, Global Study Finds. Here’s a summary of new findings reported at The Guardian: “Air pollution has become a major contributor to stroke for the first time, with unclean air now blamed for nearly one third of the years of healthy life lost to the condition worldwide. In an unprecedented survey of global risk factors for stroke, air pollution in the form of fine particulate matter ranked seventh in terms of its impact on healthy lifespan, while household air pollution from burning solid fuels ranked eighth...”
El Nino, Rising Sea Spur Record “Clear-Sky” Flooding. USA TODAY reports: “El Niño and rising sea levels linked to global warming spurred a record number of days of “nuisance flooding” last year in seven coastal U.S. cities, according to a federal report. Wilmington, N.C., recorded an all-time high of 90 days, or one-quarter of the year, partly underwater from the “clear-sky” flooding, which isn’t caused by heavy rain from a storm, the National Oceanic and Atmospheric Administration (NOAA) said in the report released Wednesday. Charleston, S.C., also topped its record with 38 days and Key West, Fla., with 14 days…” (File image: Andrew Demp, Yale).
The World’s Population is Very Slowly Backing Away from the Dangerous Coasts. Although growth and development continues to accelerate, new research suggests the growth in population is slowly spreading away from the coasts, as highlighted at Co.Exist: “…As of 2010, they found that about 1.9 billion people, or 27% of the world’s population, lived on the 9% of the planet’s land that is near the coast (defined as less than 100 kilometers from the shore at lower than 100 meters elevation). Seventeen out of 30 of the world’s largest cities are in this area, too. These population estimates come out slightly higher than previous research done in the 1990s, so the authors believe there is even more human pressure on coastal areas than we realize…” (Photo credit: May S.

Iceland Carbon Dioxide Storage Project Locks Away Gas, and Fast. The New York Times reports on promising new technology that may be able to cost-effectively transform CO2 into rock; here’s an excerpt: “…But scientists at Lamont-Doherty Earth Observatory at Columbia University and other institutions have come up with a different way to store CO2 that might eliminate that problem. Their approach involves dissolving the gas with water and pumping the resulting mixture — soda water, essentially — down into certain kinds of rocks, where the CO2 reacts with the rock to form a mineral called calcite. By turning the gas into stone, scientists can lock it away permanently…”

Madison Adopts Plan to Cut Carbon Emissions 80% by 2050. Here’s the intro to a story at Midwest Energy News: “Madison’s City Council adopted an ambitious energy plan at its meeting on Tuesday June 7, with only one no vote from the 20-member council. The plan commits the city to reduce its carbon emissions by 80 percent by 2050, reduce overall energy consumption by half by 2030, and get a quarter of its electricity, heating and transportation energy from clean sources by 2025...”

The World Lost More Than $13 Trillion Last Year Because of War. The Washington Post reports: “Violence and worsening conflict cost the world more than $13.6 trillion last year, according to an annual study of the toll of violence worldwide. That figure amounts to some 13 percent of global GDP. The analysis can be found within the Global Peace Index 2016 report, which is put out each year by the Institute of Economics and Peace, an Australia-based think-tank. It ranked 163 countries on the degree of peace within their borders…”

Can We Learn to Live Without Death? Don’t hold your breath, but some of Silicon Valley’s biggest companies are jumping into the life-extension movement. Here’s an excerpt of a good read at How We Get To Next: “…In short, our culture seems to suggest that if we radically extend our lifespans, we’re destined to become hedonistic demigods, kill ourselves, or wind up watching Friends repeats until the sun burns out. But de Grey, who has little time for the idea that an increased lifespan will inevitably lead to increased enervation and tedium, quotes a remark made by one of his friends in response: “If I’ve got a choice between Alzheimer’s at 80 or being bored at 150, I know which one I’d chose…”

This Might Get the World to Finally Pay Attention to Climate Change. Gizmodo has the eye-opening report; here’s an excerpt: “Six British warships stationed in the Persian Gulf are breaking down because the water is too hot. This week, members of the British Navy testified to the UK’s Defence Committee that their Type 45 destroyers keep losing power because of high ocean temperatures. When the ships’ turbines get overheated, they can’t generate as much energy, resulting in electrical failures. The makers of the billion-dollar warships, including Rolls-Royce and BAE Systems Maritime, claim that the ships were not designed to be used in that kind of environment for an extended amount of time, although they are supposedly engineered for a wide range of temperatures from sub-Arctic to tropic...”
Paris Floods Were “Directly” Tied to Global Warming, Study Finds. Another atmospheric fluke? Probably not, as the weather-dice are increasingly loaded for freakish flood events. Here’s an excerpt of an Andrew Freedman analysis at Mashable: “The water is still receding along the Seine and Loire Rivers in France, with cleanup beginning in parts of Bavaria, but scientists are already out with a study showing that global warming made the floods at the end of May and early June far more likely compared to a climate that had not warmed due to greenhouse gas emissions. The analysis, which is known as an extreme event “attribution study,” found that the probability of three-day precipitation extremes in April through June increased by at least 40% in France overall due to climate change, with about an 80% increase in likelihood along the Seine River Basin and close to a 90% increase in the Loire River Basin…”

Historic May Rainfall Event Across Europe. Here is an excerpt of the report from Climate Central’s World Weather Attribution unit: “...Overall, the probability of 3-day extreme rainfall in this season has increased by at least 40 percent in France, with the best estimate of about 80 percent on the Seine and about 90 percent on the Loire. All four climate model ensembles that simulated the statistical properties of the extremes are in good overall agreement. Results for Germany were inconclusive. Based on these different approaches — all of which are in agreement — the team found that global warming increased the likelihood of the heavy rains associated with the May 29 – 31 event in both the Seine and the Loire River basins. Return Times: We find that the 3-day precipitation in the Seine basin was very rare in April–June, with a return time of roughly one in hundreds of years. The event was less rare on the Loire, with a return time of roughly 1 in every 50 years...”

Is a Warmer Climate Elevating the Natural “Speed Limit” of Hurricanes and Typhoons? Check out the latest video at Climate Denial Crock of the Week: “As the 2016 hurricane season gets underway in the northern hemisphere, the new “This is Not Cool” video features interview footage shot in December with Kerry Emanuel, one of the most widely quoted and well known hurricane experts in the world. Nutshell: A warmer climate is expected to elevate the natural “speed limit” on hurricane/Tropical Cyclone wind speeds, and accompanying storm surge and destructiveness. We may already be seeing this play out...”
NATO Secretary General: “Climate Change is Also a Security Threat”. Here’s a clip from a story at The Center for Climate and Security: “…However, it’s important to note that climate change is not necessarily distinct from these other security risks, but rather, an important factor placing strains on the broader security environment in which these risks play out. Climate change will multiply stress on factors related to peace and state stability, such as water, energy, food, and migration, all of which are key elements of instability in NATO’s backyard. As NATO changes and adapts, how climate change will challenge NATO’s core missions should be a priority. As the Secretary General continues to help steer the NATO alliance, it will be important for him to connect these dots, as history will likely not be kind to a historic summit that fails to do so...”
For The Tourism Industry, There’s No Vacation from Climate Change. GreenBiz has the story; here’s an excerpt: “Vacations are supposed to be spent in paradise — on sun-kissed beaches with palm trees gently swaying overhead and clear blue waters that extend to the horizon. This is a narrative (PDF) that many tourists have come to believe — and that industry marketers have nurtured in their advertising. But climate change is making it harder for resort owners and tour operators to make good on this promise. Climate change is having more of an impact on tourist destinations by eroding beaches and bleaching coral reefs. Mountain destinations are not immune either, as a warming climate melts glaciers and snow pack…”
Arctic’s Melting Ice Creates Vicious Warming Circle. The very definition of a positive feedback loop, with negative implications for weather patterns and subsequent volatility in the planet’s weather systems. Here’s the intro to a USA TODAY story: “Arctic sea ice hit a record low in May as scientists discovered the first-ever link between melting ice in Greenland and a phenomenon known to warm the area faster than the rest of the Northern Hemisphere. The occurrence is called “Arctic amplification” and until now, scientists didn’t know Greenland was linked to it, according to a study published Thursday in the British journal Nature Communications. The phenomenon is fueled by a feedback loop where rising temperatures melt Arctic sea ice, which leaves dark open water that absorbs more warmth from the sun, thereby warming the Arctic even more.…” (Image credit: National Snow and Ice Data Center).
