The area to watch today is definitely across C IL, as a few others have mentioned. An MCV that has been moving eastward along the IA/MO border this morning will continue eastward across C IL this afternoon and evening. The biggest question for today has been cloud cover, which had been locked in place across the main focus area. However, more recently there has been a growing wedge of clearing pushing northward across NE MO and is now progressing into W IL as well. If that holds, coupled with the MCV and decent instability/moisture/shear, could have a solid threat across C IL this afternoon and evening. We’ll see how it progresses... .
