(12:00AM - 5/16/20) A storm system moving through the region will bring the chance for severe t'storms to portions of the state ton Sunday.
While a main storm system will be moving through the region, several smaller disturbances will also be passing through the area, leading to a complex and messy overall setup. Clusters of early day showers and t'storms will be ongoing across portions of the state Sunday morning. Some of this activity is likely to continue into the afternoon for some areas, while other areas potentially clear out and destabilize a bit. This will set the stage for some regeneration of ongoing activity and development of new showers and t'storms for some areas, including along a cold front that will be sweeping eastward across Northern and Central Illinois during the afternoon. Both new activity and previously ongoing activity will continue to push northeast and east across the state, through the day and into the evening, slowly ending from west to east across the state. As previously mentioned, there may be pockets of clearing and destabilization to occur. An overall environment expected to be in place will feature low instability, good moisture, good forcing and good shear. This will help support upwards minimal severe t'storm threat across a good portion of the state. Large hail and damaging winds will be the main threats, though an isolated tornado can't be ruled out. It is possible an upgrade in severe t'storms probabilities will be needed in a later update, should an area of better focus for severe t'storms become evident.
Below is the severe t'storm forecast for this event.
