9/27/19 - This Afternoon-Tonight’s Forecast...
A storm system will be pushing across the region on today. An initial round of rain and t'storms has been moving across much of Northern and portions of Central Illinois this morning into this afternoon. Isolated t'storms have been severe, with damaging winds and large hail having been the main occurrences. In the wake of this activity, additional scattered showers and t'storms are expected to develop along the cold front across Southern Wisconsin, Northern Illinois, Iowa and Missouri during this afternoon and evening. This activity will then spread across much of Northern and Central Illinois late this afternoon through Saturday morning. An environment in place featuring moderate instability, moderate moisture and moderate shear will be in place. This will help support up to a widely scattered severe t'storm threat across portions of Northern and Central Illinois. Damaging winds and large hail will be the main threats, though an isolated tornado cannot be ruled out.
