A squall line raced across southern lower Michigan during the afternoon and evening of August 29, 2022, leaving widespread wind damage in its path. This line of storms developed ahead of a cold front and tracked into the region from the Chicago area, expanding in coverage and intensity as they encountered a warm, muggy, and unstable atmosphere over Southeast Michigan. Gusts of 60 to 75 mph were responsible for damage to trees, power lines, and property and left over 375,000 customers without power. Several gustnados were reported along the leading edge of the strong gust front in Cambridge Twp, Highland Twp, Putnam/Hamburg Twp, Richmond, and Fort Gratiot, producing localized corridors of enhanced damage.
