Tim's Weather World: Get set to sweat

CT FOD01.jpg

It appears summer will end steamy.  The worst of the heat will be today and tomorrow but temperatures should remain above average all the way through Labor Day weekend.   Our RPM model is indicating the combination of heat and humidity will make it feel like nearly 100° today and over 100° for most areas on Tuesday (see images below).   The National Weather service has more detailed information on how the heat index is derived along with the hazards associated with excessive heat.


Tomorrow’s high will be in the middle to upper 90s.  It will rival July 19th as the hottest day of the year.   O’Hare hit 96° on that date.  A “back door” cold front will bring in some relief Wednesday and Thursday turning winds off the lake but highs will still be about 5 to 10° above average.  The longer range 6 to 10 day and 8 to 14 day forecasts from the Climate Prediction Center outlooks us for above average temperatures overall through the first week of September.
