Overview
On June 11 and 12, 2021, scattered thunderstorms developed across northern Illinois leading to pockets of damaging winds, hail, and torrential rainfall. The worst severe weather struck Lindenwood on June 11 and Buckley on June 12 where in both locations, significant wind gusts in excess of 70 mph snapped trees and wind-driven hail pelted buildings. Finally, while some areas saw much-needed rainfall that amounted to over 1-2 inches, many others remained completely dry.
