Of greatest concern at the moment are the two supercells.  One is near Covington with potential of marble hail & gusts to 55 mph.  It is moving eastward.

The other is southwest of Champaign.  That one is showing more northeasterly component to the track.

Line responsible for a lot of wind damage from eastern Iowa, through northern Illinois is approaching I-55.  This will clip area as a broken line later this evening.

Wind fields are strong through the atmosphere with plenty of speed shear & slight directional shear, which supports severe weather.  Good thing is that we have had stubborn cloudiness around a good chunk of the area today, which has limited the instability some.  All the cloudiness here & northeast of our area is tending to limit severe & keep the worst of it eastern Iowa to northern Illinois.

Regardless, some severe risk continues until 11 p.m. with potential of a couple/few storms producing wind, hail, brief, weak tornado.

Storm Prediction Center has 40% chance of a Severe T'Storm Watch being issued for the area.

Here are the latest trends for the evening.  Only change I see making to the forecast is inserting the potential of a few lingering showers into early Wednesday morning (25%) as takes a little while longer to get the cold front through.
