Thunderstorm Wind in St. Clair County, Michigan

Numerous roads were closed due to downed trees and powerlines over southern Port Huron.

Line of showers and thunderstorms rapidly developed from northern Ohio to northern lower Michigan early in the afternoon of the 5th in advance of an approaching cold front. Scattered storms within this line became strong to severe as they crossed southeast Michigan leading to areas of wind damage over the northern Metro Detroit area as well as into the eastern Thumb. While this occurred, a spin-up tornado occurred over Livonia resulting in tree damage/downed trees along its path with one large tree falling on a home unfortunately killing a 2 year old boy and critically injuring his mother as they slept.
