The Storm Prediction Center has much of the area at a Level 2 risk for severe storms, with some areas in the northwestern part of the area under a Level 1 risk and Northwest Indiana and some far south suburban areas under a Level 3 risk.

Butler says temperatures will be slightly cooler than Tuesday, but humidity remains high.

The area will dry out on Thursday, and temperatures will become very hot, climbing into the mid-to-upper 90s heading into the weekend.

The heat index is expected to be above 100 degrees on Sunday and Monday.
