Extreme Heat Southwest of Area Today (Heat Index to 120!)August 23rd, 2014 at 10:07 pm by Chad Evans 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.
