The episode as NWS GRR wrote it up.
A winter storm produced heavy snow across most of southwestern and south central lower Michigan, dumping anywhere from 12 to 18 inches of snow to the north and west of the track of the low pressure system, to under 4 inches across far south central lower Michigan close to the track of the low. Snow developed well out ahead of the low pressure area during the early morning hours of the 2nd and continued through the day. Once the low pressure area passed by to the east lake enhanced snowfall began. Approximately 16 inches of snow fell across Mason, Oceana, Muskegon, Ottawa, Allegan, and western Kent counties. The maximum snowfall reported was in Ludington (Mason county), where 18" of snow fell. A foot or more of snow fell across Lake, Osceola, Clare, Newaygo, Mecosta, Isabella, Montcalm, Ionia, and western portions of Barry and Kalamazoo counties. Generally 8 to 10 inches of snow fell across Gratiot county. Much lighter snowfall totals of less than 6 inches were reported across Clinton, Eaton, Ingham, Calhoun and Jackson counties.
