5:40 P.M. UpdateJuly 12th, 2014 at 5:16 pm by Chad Evans under Chad's WLFI Weather Blog
The heat is like a wall to our west. It is currently 96 at St. Louis’ Lambert Airport. Some weather stations are reading as high as 99 in the St. Louis area, while the 90-degree line resides across central Illinois. As far north as Peoria & Bloomington, Illinois, heat indices are near/over 100.
For us, after dim sun, large area of altocumulus convective debri has overspread the area. Skies are overcast at West Lafayette now. This is keeping temperatures between 76-81, but dew points are in the 68-74 range. Winds are gusty from the south & southwest. Warmest is Covington at 81 with dew point of 73 & Kokomo with 81 & a dew point of 70.
I have 78 with a dew point of 72 after 0.26″ rainfall earlier. Kentland picked up 1.04″, Morocco 0.70″, but Frankfort 0.09″.
18z NAM shows the storms forming a line just northwest of our area at 10 p.m. & bring them through overnight before their rains completely exit Sunday morning. Then, with sun & break with breezy, very warm, humid conditions, new broken line of storms pops later in the day.
Scattered severe gusts are still possible tonight. Isolated small hail/brief, weak tornado cannot be ruled out. Also, broken line tomorrow may have have a few severe gusts/bit of hail.
