What happened
The episode as NWS DTX wrote it up.
A warm and sticky summertime day in southeast Michigan, with dew points well into the 70s. A few thunderstorms developed in the area, most of which were not especially strong. However, one thunderstorm in Monroe County evolved into a supercell, and produced an impressive swath of wind damage. Scores of trees were downed from the Maybee area to south of LaSalle. The most concentrated damage occurred along W Albain Road, just west of Telegraph Road (US-24) - between the city of Monroe and LaSalle. Here, two cars and one home were struck by falling trees, and a metal barn was heavily damaged.
The radar
The Detroit radar (KDTX), 78 km away, was scanning. The volume nearest the first event began at 00:27 UTC.
