During the evening hours, thunderstorms began to initiate in a moderate to strongly unstable environment along a southwest to northeast oriented surface cold front located in Wisconsin and extending into the Upper Peninsula of Michigan.  The storms quickly grew upscale into a linear MCS and raced to the east toward Lake Michigan. The convective system began to come ashore in lower Michigan during the late evening hours. The storms from Muskegon County to the north maintained their strength and produced numerous reports of widespread tree damage and a few reports of large hail, though storms along the line southward from Muskegon County weakened significantly as they approached the Michigan shores. However, widespread wind damage was still observed with a very strong gust front that advanced quickly ahead of the leading line of convection. The gust front produced winds of 50 to over 60 miles per hour and numerous reports of downed trees and power lines.
