Unofficial Snowfall Maps
This snowfall analysis is not official data. It is the National Weather Service's best estimate of how much snow fell across southwest Michigan during the specified time period, using reports from local law enforcement agencies, volunteer spotters, and road commissions. In many cases, the reports received by the NWS are only rough estimates and are not official measurements. Although we will make every effort to produce a map after each significant snow event, an updated graphic cannot be guaranteed on a consistent basis.
