The storms have already caused significant disruptions, including power outages affecting over 1,000 customers in LaSalle County, Illinois. Tornado damage has been reported in Menasha, Wisconsin, and flash flooding poses a Level 2 out of 4 risk across parts of Illinois, Pennsylvania, and West Virginia. Tuesday’s severe weather threat will shift southward, increasing flash flood risks in the central Appalachians and southwestern Ohio. Rainfall totals in some areas may exceed half a foot by Thursday, heightening the risk of localized flooding and property damage.
