Excessive Heat Warning Posted Thru Friday
Here's a forecast with rare 100 percent accuracy. Men will sweat. Women will glow. Dogs will pant. All of us will wonder (out loud) how Minnesota can possibly get this hot? 5 months ago some of us were driving on area lakes. Now they're an inviting refuge from jungle-like heat.
An Excessive Heat Warning means a significant risk of heat-related ailments into Friday. The ill and the elderly are most vulnerable. Staying hydrated and avoiding afternoon sun helps, but the threat is real. We're just not acclimated to this level of heat and humidity, more typical of the Middle East than the Midwest.
Reminder: check on friends and family, don't even THINK about leaving kids in the car, and don't forget about pets! They feel the heat as much as we do.
The arrival of tropical heat sets off a few T-storms today; enough afternoon sun for low 90s with a heat index of 100-105F. Mid 90s and a dew point near 80F tomorrow (ack!) will make it feel like 110F by the dinner hour.
Severe storms on Saturday mark the leading edge of sweet relief. Low 80s early next week will feel like a vacation.
THE NATIONAL WEATHER SERVICE TWIN CITIES HAS ISSUED AN EXCESSIVE HEAT WARNING...
WHICH IS IN EFFECT FROM 1 PM WEDNESDAY TO 7 PM CDT FRIDAY. THE EXCESSIVE HEAT
WATCH IS NO LONGER IN EFFECT. * TEMPERATURES: HIGHS IN THE MID 90S AND LOWS IN THE MID 70S... TO POSSIBLY LOWER 80S IN THE TWIN CITIES METRO AREA. * DEW POINTS: 75 TO 80 DEGREES...LOCALLY HIGHER. * HEAT INDICES: WIDESPREAD 100 TO 110 DEGREES...LOCALLY HIGHER. * IMPACTS: A HEIGHTENED RISK OF HEAT RELATED ILLNESS... ESPECIALLY FOR THOSE ACTIVE OUTDOORS OR FOR THOSE WITHOUT AIR CONDITIONING. * TEMPERATURE...HIGHS IN THE MID TO UPPER 90S AND LOWS IN THE MID TO UPPER 70S...TO POSSIBLY LOWER 80S IN THE TWIN CITIES METRO AREA. * IMPACTS...A HEIGHTENED RISK OF HEAT RELATED ILLNESS... ESPECIALLY FOR THOSE ACTIVE OUTDOORS OR FOR THOSE WITHOUT AIR CONDITIONING.
- Cover windows that receive morning or afternoon sun with drapes, shades, awnings, or louvers. (Outdoor awnings or louvers can reduce the heat that enters a home by up to 80 percent.)
- Keep storm windows up all year.
- Listen to local weather forecasts and stay aware of upcoming temperature changes.
- Know those in your neighborhood who are elderly, young, sick or overweight. They are more likely to become victims of excessive heat and may need help.
- Be aware that people living in urban areas may be at greater risk from the effects of a prolonged heat wave than are people living in rural areas.
Is "Corn Sweat" Making The Heat Wave Worse? Probably, by at least a couple of degrees. Angela Fritz explains at Capital Weather Gang: "...Corn sweat is an extremely simple way of referring to evapotranspiration, the process by which moisture in plant leaves evaporates into the air. Plants draw water out of the ground through their roots for photosynthesis, and the water in the plant cells is exposed to the air once it gets above the ground. It evaporates off the leaves just as sweat evaporates off our skin — although it doesn’t take place to keep the plant cool, like it does for us. So evapotranspiration is not making things hotter. But it is making things more humid — which can certainly be just as bad..."

Arctic Sea Ice Falls To Record Low in June. Here's the intro to a story at UPI.com: "Sea ice cover in the Arctic beat a hasty retreat throughout June, reaching record-breaking levels by month's end. Data published by the U.S. National Snow and Ice Data Center last week showed average sea ice extent for June was 100,000 square miles smaller than in 2010, the year of the previous June record. Almost every month this year has set new record lows for sea ice extent. March, however, was the second-lowest, slightly greater than 2015. The average sea ice extent for June was 4.09 million square miles..."

* Check out the new and improved Springbrook Nature Center for yourself. This is where the July 18, 1986 tornado spent most of its time, ripping trees out of the park as if they were weeds. You can still see some evidence of the tornado, but park staff and volunteers have done a wonderful job creating a remarkable urban park unlike any other in the Twin Cities metro.
Deadliest State for Tornadoes? Alabama. Huh? In its defense, residents of Oklahoma, Texas and Kansas - the heart of "Tornado Alley" are generally more tornado-aware; it's easier to spot and track deadly tornadoes on the Plains than hilly, wooded sections of the Mid South, and many tornadoes east of the Mississippi are rain-wrapped and very hard to see, especially at night. Throw in more trailer parks (per capita) and you have a higher overall risk for Alabama than Oklahoma, according to KOCO-TV: "Over the last 30 years the state with the most tornado-related deaths is Alabama. Alabama averages 14 tornado-related fatalities each year, followed by Missouri with eight. Arkansas averages five each year and Texas, Mississippi, Georgia and Oklahoma all average four. The major tornado outbreak of 2011 pushed Alabama's and Missouri’s averages way up with the Joplin tornado responsible for 161 deaths and tornadoes in Alabama killing 238 on April 27 and 28..."

Artificial Intelligence Swarms Silicon Valley on Wings and Wheels. Here's an excerpt from an interesting New York Times story: "...Now Silicon Valley has found its next shiny new thing. And it does not have a “Like” button. The new era in Silicon Valley centers on artificial intelligence and robots, a transformation that many believe will have a payoff on the scale of the personal computing industry or the commercial internet, two previous generations that spread computing globally. Computers have begun to speak, listen and see, as well as sprout legs, wings and wheels to move unfettered in the world..."

Increased Asthma Attacks Tied To Exposure to Natural Gas Production. InsideClimate News has the story; here's the intro: "Exposure to more intense shale gas development correlates with a higher risk of asthma attacks among asthma patients, according to a new study of Pennsylvania's Marcellus Shale, one of the nation's largest and most active fracking regions. The paper, published Monday in JAMA Internal Medicine, a publication of the American Medical Association, didn't examine the exact cause of the trend. But lead author Sara Rasmussen, a Ph.D. candidate in environmental health sciences at Johns Hopkins Bloomberg School of Public Health, said air pollution and stress are both plausible explanations..."

Climate Change is Making Farm Work More Dangerous Than It Already Is. FUSION has an interesting story; here's an excerpt: "...There can be little argument that farm workers are among the most at-risk. “There is absolutely an association between climate change and the health of agricultural workers,” said Dr. Marc Schenker, director at the Center for Occupational and Environmental Health at UC Davis. “The health effects of climate change on workers are diverse, and range from heat stress to infectious diseases, and possibly kidney disease...” (Image credit: Omar Bustamante/FUSION).
