(10:00PM - 5/12/20) A storm system moving through the region will bring the chance for severe t'storms to portions of the state on Thursday.
Early day showers and t'storms are expected to be ongoing across Northern Illinois Thursday morning. It is possible a few of these t'storms will be strong, with small hail being possible. In the wake of this activity, some clearing and destabilization will occur ahead of an advancing cold front. Scattered showers and t'storms are likely to develop during the afternoon along and ahead of this cold front, across Northern Illinois into Iowa. This activity will then push eastward across Northern and Central Illinois, Thursday afternoon into Thursday night. The environment in place is expected to feature decent instability, good moisture, good forcing and good shear. This will help support upwards of a limited severe t'storm threat across much of Northern and Central Illinois. Large hail and damaging winds will be the main threats, though an isolated tornado can't be ruled out.
Below is the severe t'storm forecast for Thursday - Thursday night.
