What the National Weather Service wrote

Widespread tree and powerline damage over northern half of Kalkaska county between approximately 1055 and 1125 PM.

The wider storm

After a warm front mixed northward across northern Michigan during the day, a weak shortwave progressing overhead helped initiate storms along a weak boundary over Lake Michigan. This line of storms tracked eastward across the area, producing damaging winds into the early morning hours of 8-11. Training storms across parts of NW lower Michigan also produced heavy rainfall and flash flooding in multiple locations, including washing out a roadway in Antrim county that resulted in one injury.

Began near Kalkaska (44.7300, -85.1800).
