Extreme Heat Southwest of Area Today (Heat Index to 120!)

August 23rd, 2014 at 10:07 pm by under Chad's WLFI Weather Blog

The heat & high heat indices southwest of us today were extreme!

Check out the observations from Cairo (Illinois) Airport.  With 99 & dew point around 80, the heat index was pushing 120 this afternoon!


In south-central Illinois at Salem, the heat index was near 120, as well.  The 15:35 observation was a 119 heat index!


Notice Centralia (also in south-central Illinois) hit 102 with a heat index as high as 115.


This intense heat is expanding northward & will bring +90 to our area Sunday through perhaps Wednesday.  Our high today was 88 at 2:30 p.m. (with a peak heat index of 98) before it turned mostly cloudy, then storms arrived near 4:15, knocking it back to 71.

    I can confirm the Centralia temp..I’m down in southern Illinois and its one of those times when its so hot and humid that its hard to breath. Tried to have a b-day party yesterday..needless to say it got moved indoors. We have definitely been spoiled with our cool summer back home

  2. It is certainly miserable outside! Radar is amazingly clear right now, but am betting it will look like popcorn in a few hours ;)

    Praying for those in CA where the earthquake hit. Every part of the country/world has some kind of severe weather.

    MA In REM Just home from church and am planning to stay INSIDE the rest of the day!
