Lightning in Washtenaw County, Michigan

Southeast Michigan saw active weather in both the morning and afternoon on Wednesday, June 18th, with the afternoon convection turning severe. Previous convection during the morning hours had moved to the east and there was enough instability for the thunderstorm complex over southern Wisconsin and northern Illinois to hold together as it crossed Lake Michigan and into Lower Michigan. This line of storms raced across the state bringing winds, heavy rain, and frequent lightning with numerous reports of trees down, power outages, and local flooding.
