Greatest severe threat likely stays across IL. pic.twitter.com/EbyOes3NRx
Large hail will likely be the greatest threat with any storm that develops this afternoon or evening. There is the potential a tornado threat could develop for places along the WI-IL border this afternoon or evening. Most of the ingredients will be in place for severe weather. The big question is will the most warm, moist and unstable air make it far enough for the tornado threat to materialize.The greatest tornado and severe weather threat will likely stay just south of the area. A severe weather outbreak is likely across parts of IL.

Rainfall totals this weekend will likely range from 0.5-1.5" of rain. Locally higher amounts will be possible. This much rain could cause a rise in our local river and lake levels and cause flooding.
