Low pressure moved across southern Ontario and pulled a strong cold front across the region during the evening hours. Thunderstorms which accompanied the front produced wind gusts up to around 70 mph. The strong winds downed trees and power lines and poles. Power outages were scattered throughout the region with utilities reporting several thousand without power at its worse. In Alden, the winds tore the roof off a garage and threw it about one hundred feet downwind. In Caledonia, a metal shed was blown over.
