It's not as dramatic or visually compelling on television as a tornado, hurricane or flood, but excessive heat is America's deadliest weather phenomenon - directly or indirectly claiming an average of 1,000 U.S. lives every year.
I hope high school football coaches take the heat seriously, scheduling light workouts and extra water breaks in the coming days. Pushing kids in extreme heat doesn't make them tougher; it does increase the risk of cramping, nausea, even heat stroke, which can be deadly.
The elderly and chronically ill are more vulnerable to heat-related ailments. Log off from Facebook (Faceplant) and physically check in on older neighbors/friends to make sure they're OK.
After simmering above 90F today & Wednesday a thundery cool front provides temporary relief Thursday into early Friday. Another surge of 90s overspreads Minnesota next weekend; some of the models show a few mid-90 F. "spikes" into Labor Day weekend. So much for an abbreviated "Yukon Summer".
Nothing a quick dip in the lake or pool can't cure.
Useless trivia: most people can estimate the air temperature to plus/minus 3 degrees. No thermometer? Count the number of cricket chirps in 15 seconds and add 37.
Low-tech, but it works!

Peak Heat: Next Weekend Into Early Next Week? Today will be hot enough, low to mid 90s, but ECMWF guidance is hinting at the main surge of heat pulsing northward into Minnesota and Wisconsin from Saturday into Tuesday of next week; a few days in the mid-90s can't be ruled out. The arrival of more comfortable air Thursday (dew points drop into the 40s and 50s for 24 hours) may set off a few strong T-storms late Wednesday and Wednesday night. Graphic above: WeatherSpark.
Slight Severe Threat Wednesday. Minnesota has experienced only 6 tornadoes, to date, according to SPC. We should have seen closer to 25 by late August, but unusually cool, dry, Canadian air took the edge of our severe storm risk from mid-July into mid-August. We'll have enough low-level moisture for a few strong storms tomorrow - wind shear is marginal, so there's a greater risk of hail and straight-line winds than tornadoes. A cool frontal passage may spark a few severe storms late Wednesday, according to SPC.
100-Degrees In September? I'm not buying this solution (yet), but the GFS model predicts a run of 90s from late August into the first week of September, going so far as to print out a high of 100F on September 3. At this point that's more of a "guess-cast" than a forecast, but we'll keep an eye on the trends, from one model run to the next, and see if this extended heat spike is for real. At the rate we're going we could make up for lost time (and heat).

A Super-sized Summer. Drought or flood, record heat or record chill, wildfires or sweatshirts? In today's edition of Climate Matters we take a look at some of the jaw-dropping extremes across the USA, take a look at trends worrying U.S. Forest Service officials, and find the one thing America doesn't have to worry about - at least not yet.
10 Years Of Weather History In 3 Minutes. So long GOES-12. We'll miss you. A "planned retirement" of a weather satellite that proved essential in recent years; details from NOAA: "NOAA's GOES-12 satellite was decommissioned on August 16th, 2013 after 3,788 days in service. From April 2003 -- May 2010, GOES-12 served as GOES East, providing "eye in the sky" monitoring for such memorable events as the 2005 Atlantic hurricane season and the series of blizzards during the winter of 2009-2010. After suffering thruster control issues, GOES-12 was taken out of normal service and moved to provide greater coverage of the Southern Hemisphere as the first-ever GOES South. During that time it provided enhanced severe weather monitoring for South America..."

Here's How 16 Big Companies Are Profiting Off Global Warming. Here's a clip from Huffington Post: "...Automakers producing hybrid cars like Ford, Honda and General Motors could be poised to cash in if a pinched oil supply pushes gas prices up, according to a 2007 USA Today report citing Wall Street analyses. In addition, Toyota officials have noted on earnings calls that concerns over global warming help boost the company because it's known for its fuel efficient and hybrid models like the Prius. Other companies have found different ways to profit off making our doomed future a little bit better for everyone. Take Daikin Industries, a maker of energy efficient air conditioners or Rayonier, a timber supplier looking for ways to produce timber that don't release carbon dioxide into the atmosphere. Those companies have a successful future in our new world, Nicolas Huber, the head of a fund that invests in companies poised to thrive in a hotter environment, told US News in 2008..."(Photo: AP).
