A Tornado Watch was in effect until 1 a.m. for Kendall and La Salle counties. ABC7 meteorologists Larry Mowry said that based on the strength of the storm, which weakened as it moved, the chances of a tornado forming that late were relatively low.
There were reports of storm damage including downed trees and power lines in Boone County, and reports of people stuck in their cars due to those downed trees and power lines. No injuries have been reported.
Wind gusts of up to 60 miles per hour have also been recorded in the western suburbs. The storms are featuring heavy, frequent lightning and high winds. They are expected to decrease in intensity as they move towards Lake Michigan.
