The episode as NWS IWX wrote it up.
A strong warm front surged north into Lower Michigan during the early morning hours of the 9th. Steep lapse rates and abundant lift with the front along allowed for several rounds of showers and a few thunderstorms to persist across portions of far southern Lower Michigan. Reports of four to over five inches of rain were received across portions of Hillsdale County, especially in the Litchfield area where several roads were flooded and impassable.
