Peak Summer: Real Heat Wave Brewing Next Week?
“If you saw a heat wave, would you wave back?” asked comedian Steven Wright. We may get a chance to find out, first hand, next week.
My TV screen is already cluttered with back to school commercials, but please don’t be fooled: we have plenty of summer left to enjoy. And endure.
Historically this is the hottest week of the year, when torrid heat from the desert southwest stands the best chance of reaching Minnesota. A splash of Canadian air drops temperatures into the 70s later this week, but models continue to hint at a full-frontal hot front next week. NOAA’s GFS model prints out 100 degrees in the MSP metro the end of next week. I’m not buying it (yet) but you’ve been warned. 90s should be commonplace next week, with gasp-worthy heat indices lingering into late July, possibly longer.
The warmer the air, the more water vapor floating overhead – more moisture to spike storms. 4 to 6 inch rains fell Monday from near St. Cloud to Alexandria into the Brainerd Lakes area, with up to 8″ in a few spots. That’s 1-2 month’s worth of rain in one day. On Sunday Sioux Falls set a gasp-worthy dew point record: 82F. More details below.
No, summer isn’t even close to being over. The hottest days are yet to come.
NOAA’s Models Had The Right Idea. I shared a looping version of this yesterday morning, before the monsoon rains actually set up. Sunday PM’s 4 KM NAM run was printing out some extreme, 6-8″+ amounts for far northern Minnesota, which I thought was much too high at the time. But with a dew point of 82F reported in Sioux Falls, incredible levels of water vapor floating overhead, the fuel was, in fact, available for record rains and serious flash flooding.

Potentially Catastrophic Flooding For Parts of the Northland. I fear Duluth News Tribune has the right idea with the extreme rainfall amounts from Monday’s training T-storms. Much like the cars in a train pass over the same section of track, repeated waves of heavy to severe storms tracked across the same counties, resulting in some 5-8″ rainfall amounts, possibly more in some areas. Here’s an excerpt: “…At 9:40 p.m., the Weather Service issued a “flash flood emergency” for Pine County, relaying reports from local authorities that “many state, county and local roads are underwater, and some road washouts have been reported in the Sturgeon Lake, Willow River, Denham, Bruno, Askov and Sandstone areas.” At about 9 p.m. the Weather Service issued an alert asking for help notifying “campgrounds, resorts, anyone near rivers or streams … in and around the Brainerd Lakes area, Aitkin County, Pine County, and much of Northwestern Wisconsin (that) we are expecting potentially catastrophic flooding...”
Storm Damage to Homes in Litchfield. Here’s a photo posted by KARE-11 photographers of fairly extensive damage in the Litchfield area.
More Photos of Litchfield Tornado. Here’s an excerpt of some of the photos posted at Willmar Radio: “This photo was taken by Neal Thompson near Highway 12 and 5th Street in Litchfield, near the Dairy Queen. Other photos by Deb Pearson and Sabrina Mccorquodale.”
Overshooting Tops. Significant tornadoes usually don’t form in squall lines, surrounded by other T-storms. The rotating supercells that ultimately spin up tornadoes are greedy. They want (need) a steady supply of warmth and moisture, which becomes problematic with linear storms and outflow boundaries of rain and hail-cooled air. Watch the isolated cells out ahead of the main line of severe weather – this is where tornadoes are most likely to form. If you look carefully on the late afternoon satellite loop you can see a little knob on top of the thunderhead sweeping across central Minnesota, the “overshooting top” marking the most intense updraft within the tornado-generating mesocyclone.

Late Month Heat Wave? If this (GFS) solution for 500 mb winds 2 weeks from now verifies we’ll be sweating out the last half of July; although the worst of the (100-degree?) heat may slide just to our south across Iowa toward Chicago and Detroit. Too early to tell, but the maps look hot for much of the USA.
Record Dew Point at Sioux Falls. Anything above 70F is considered oppressive by most people (unless you live in Florida, then it’s just another day at the beach). But a dew point of 82F? Impressively oppressive. Ghastly. More details from the Aberdeen National Weather Service Office.
We Just Broke The Record for Hottest Year, 9 Straight Times. The Guardian has details: “2014 and 2015 each set the record for hottest calendar year since we began measuring surface temperatures over 150 years ago, and 2016 is almost certain to break the record once again. It will be without precedent: the first time that we’ve seen three consecutive record-breaking hot years. But it’s just happenstance that the calendar year begins in January, and so it’s also informative to compare all yearlong periods. In doing so, it becomes clear that we’re living in astonishingly hot times…”

Heat: #1 Weather Killer in the USA. 30-year data from NOAA confirms that heat consistently claims more lives than flooding, lightning, or extreme storms. Since 1986 an average of 130 Americans have succumbed, directly or indirectly, to excessive heat – more than 3 times the death toll from winter cold and storms.
Alberta Wildfires Costliest Disaster in Canadian History. Climate Central has specifics: “The Fort McMurray wildfire, driven by drought and climate change, was the costliest natural disaster in Canadian history, ringing up $3.58 billion in losses, according to the Insurance Bureau of Canada. The wildfire, which ignited May 1 in eastern Alberta and was brought under control on July 5, forced Canada’s largest-ever evacuation. It scorched more than 1.4 million acres and destroyed 2,400 homes and other buildings in and around Fort McMurray, the hub of Canada’s oil sands industry…”

8 Billion-Dollar Weather Disasters So Far in 2016. Here are a couple of excerpts from Cattle Network: “The weather can be cruel, and it can be costly. So far in 2016, eight distinct events caused $13.1 billion in total damages and claimed 30 lives….According to NOAA, there were 10 distinct billion-dollar weather events in all of 2015 and 8 in 2014. For more information, visit www.ncdc.noaa.gov/billions/events.”

Seattle Crowned “Least Severe” Weather Spot In The Nation. Not a good place to chase tornadoes. Here’s an excerpt from KOMO News: “Fresh off last month’s blog showing Seattle was the only spot in the lower 48 with no severe thunderstorm warnings this year comes more research that cements Western Washington as among one of the most boring places in the nation when it comes to severe weather. Ian Livingston with the Washington Post’s Capital Weather Gang has been looking into the effectiveness of the National Weather Service’s social media efforts in getting severe weather warnings to the public, also learning more about when you can be expected to get severe weather warnings…”

Stop Drinking Bottled Water. A bad habit I need to break as well. Here’s a clip from Gizmodo: “…Clean, safe drinking water that flows freely out of our faucets is a feat of engineering that humans have been been perfecting for two millennia. It is a cornerstone of civilization. It is what our cities are built upon. And over the years the scientists and hydrologists and technicians who help get water to our houses have also become our environmental stewards, our infrastructural watchdogs, our urban visionaries. Drinking the water these people supply to our homes is the best possible way to protect future access to water worldwide. Even after public water crises like Flint—especially after public crises Flint. Companies that package water in a single-use bottle are not concerned with the future…” (Image: change.org).
Pilot Captures Incredible Nighttime Thunderstorm Photo Over the Pacific Ocean. Tip of the hat to Capital Weather Gang for sharing one of the more amazing CB photos I’ve ever seen: “This is one of the most striking thunderstorm photos we’ve seen. Taken from a plane at the moment of a lightning flash, it illustrates both the ferocity of a turbulent atmosphere and the beauty of Mother Nature. A strong, roiling updraft; a smooth, flat anvil; and the overshooting top — all features of intense developing thunderstorms. The photo was taken over the Pacific Ocean from the cockpit of an airplane. The photographer and pilot, Santiago Borja, says he was circling around it at 37,000 feet altitude en route to South America when he captured this spectacular view...”

wettest June since records began in some of the Netherlands, but that’s no reason for the Dutch to be despondent. A small group of entrepreneurs has demonstrated that it’s the perfect excuse to make beer, launching a brew made from rainwater. The idea is that with climate change linked to increased rainfall in the Netherlands – just as in the UK – they might as well use it as a business opportunity...”It may have been the

Food Shortages and Sea Level Rise U.S. Voters’ Top Climate Change Concerns. The Guardian has the story: “…Diminishing food and water security and ruinous sea level rise are the leading climate change concerns of a section of the American electorate that is aghast at the lack of discussion of global warming during the presidential debate. A Guardian US survey of its readers found that pressure on food and water supplies is considered the most important consequence of climate change. Sea level rise, which is set to inundate coastal areas currently occupied by millions of Americans, is second on the list of the most urgent issues…” (File photo: Nick Ut, AP).
Minnesota Advocates “Pleasantly Surprised” With New U.S. Bancorp Climate Policy. Here’s the intro to a story at Midwest Energy News: “Minnesota climate activists say they are “pleasantly surprised” after Minneapolis-based U.S. Bancorp issued a new environmental policy in June that will reduce lending for coal-fired power plants, coal mines and other environmentally harmful projects. Two bank officials have been meeting with MN350 members for the past several months on a new environmental policy that would discourage lending to fossil fuel interests. Advocates say the policy move — which they add could be stronger — is important because U.S. Bancorp (the parent company of U.S. Bank) is one of the largest financial services companies in the United States...”

ExxonMobil: New Disclosures Show Oil Giant Still Funding Climate Science Denial. Here’s a clip from DeSmogBlog: “…But the latest disclosures on donations by ExxonMobil, reported publicly here for the first time, show it continues to support organisations that claim greenhouse gases are not causing climate change, or that cuts to emissions are a waste of time and money. Organisations including the American Enterprise Institute, the American Legislative Exchange Council and the National Black Chamber of Commerce — all organisations with a record of misinformation on climate science — all received grants in 2015 from ExxonMobil. The 2015 tally brings the total amount of known Exxon funding to denial groups north of $33 million since 1998…”
Changing Cloud Patterns Could Lead to More Global Warming. Here’s a snippet of a story at InsideClimate News: “…Cloud patterns have been shifting over the past 30 years in ways that a new study says are possibly due to global warming––and may even lead to more warming in the future. Climate scientists believe cloud changes are one of the biggest sources of uncertainty in climate models and understanding how cloud patterns respond to rising greenhouse gas levels is critical to determining how much and how quickly global temperatures will rise. This new study, published Monday in the journal Nature, provides for the first time a reliable record of past cloud changes spanning nearly three decades and a comparison of those changes with climate models…” (Image credit: NASA).

Another Inconvenient Truth: It’s Hard To Agree How To Fight Climate Change. The New York Times reports; here’s an excerpt: “…But the movement that started with a straightforward mission — to get more people to appreciate the dangers of climate change as a precursor to action — is feeling growing pains. What may seem like a unified front has pronounced schisms, with conflicting opinions on many issues, including nuclear power and natural gas, that are complicating what it means to be an environmentalist in this day and age. The factional boundaries are not hard and fast, with groups shifting their positions as the science and waves of activism evolve...” (File image: earth.nullschool.net).
Have Conservatives Noticed Their Favorite Climate Talking Point Has Been Obliterated? The “pause”? Never mind. Here’s an excerpt from The Week: “…Several years ago, it seemed like that crowd had a perfect argument to justify inaction on climate: the global warming “pause.” Measurements of global atmospheric temperatures were not quite increasing on the exact path predicted by climate models. Climate science was “troubled,” wrote Will Wilkinson. The “warming plateau is…effectively killing the rationale for green policies that limit growth,” wrote Walter Russell Mead — hence seeming to justify a policy of “focusing first on areas where the problems in our common life are more immediate,” as Ross Douthat put it two years ago. But lo and behold, two years later warming has surged back with a vengeance. First 2014 was measured as the hottest year on record by a slight margin, then 2015 broke that record by a bit more, and now 2016 is set to obliterate the record again, this time by a huge margin...”

Can New York Be Saved In The Era of Global Warming. Jeff Goodell reports at Rolling Stone; here’s an excerpt: “…The problem for New York is, climate science is getting better and better, and storm intensity and sea-level-rise projections are getting more and more alarming,” says Chris Ward, the former executive director of the Port Authority of New York and New Jersey, the agency in charge of airports, tunnels and other transportation infrastructure. “It fundamentally calls into question New York’s existence. The water is coming, and the long-term implications are gigantic…”
