What happened

The episode as NWS GRR wrote it up.

Several large hail producing thunderstorms developed during the early morning hours of the 9th along and just north of a warm front that moved up into far southern lower Michigan. A severe thunderstorm that moved through Van Buren county produced three quarters inch hail in Mattawan, and one inch hail in Bangor, where local law enforcement officials reported that the hail briefly covered the ground. Three quarters inch hail was also reported in Gobles (Van Buren county), where local law enforcement officials reported that a hail depth of 3 inches on the ground was briefly observed. Large hail was also reported 2 miles northwest of Alamo, in Kalamazoo county, where a trained spotter noted that the hail lasted for 5 minutes before ending. Finally, one inch hail was reported by a trained spotter in Bellevue, in Eaton county.
