Numerous reports of wind damage were received, with multiple trees down in the hardest hit areas of Lenawee, Monroe, Wayne, and portions of Oakland counties. The damaging winds of 60+ mph, resulted in at least 60,000 customers losing power across portions of southeast Michigan. The severe thunderstorms occurred south of a stationary boundary draped near the I-94 corridor, with a moist and unstable boundary to the south of it across far southern Lower Michigan into the northern Ohio Valley.

In addition to the numerous wind reports, the first tornado of 2021 occurred in Riga Township, located in far southeast Lenawee county. This was the first tornado in southeast Michigan since September 2019 in Sanilac county. The Riga tornado was rated EF-1 with estimated peak winds of 90 mph and a path length just shy of 3 miles. The tornado was the first in Lenawee county since an EF-1 tornado that occurred northwest of Adrian back on June 6, 2010.
