This afternoon-tonight...
Isolated to scattered showers and t'storms will be possible this afternoon and evening across Southern Illinois. This activity is associated with a left over disturbance that is caught under the building ridge of high pressure in the region. An environment characterized by low instability, moderate moisture and low shear will be in place. This will aide in an isolated severe t'storm threat across Southern Illinois, with wind and hail being the main threats. Of greater focus is further north, where a large complex of rain and t'storms is currently pushing across Minnesota and Iowa. This complex is expected to push east-southeastward into portions of Northern Illinois later this afternoon, continuing into tonight. An environment characterized by high instability, high moisture and low shear will be in place. This will help support up to a scattered severe t'storm threat for portions of Northern Illinois, with wind and hail will be the main threats. Should a widespread/significant damaging wind threat look increasingly likely based on observations, the potential exists for a further upgrade in severe t'storm probabilities in future updates.

Friday Morning-Friday Night...
A weakening complex of rain and t'storms may be ongoing across portions of Northern Illinois Friday morning. In the wake of this potential early day activity, scattered showers and t'storms will likely develop during the afternoon across portions of Missouri, Iowa, Wisconsin, Northern and Western Illinois.
