People across southern Wisconsin awoke to white grounds Saturday morning as the first one inch snow fell across most of the area through the overnight hours. The snow began in southwestern Wisconsin late Friday evening and spread to the east through the overnight hours, lasting into Saturday afternoon. All counties in southern Wisconsin except for Sheboygan reported at least an inch of snow as the snow passed through the region. Northeasterly winds helped to generate a lake effect snow band along Lake Michigan, allowing Sheboygan County to record at least a tenth of an inch and the rest of the lake counties to observer an additional inch or more.
As noted from the graphic below, the heaviest snow fell over Lafayette, Iowa, Sauk, Dane and Green counties, with decreasing reports as you head to the east and north. These reports are a combination of CO-OP observer reports, who provide one report between the hours of 6 and 8 am with details from the previous 24 hours, and trained spotter reports, who call in at random times with a report up to that particular time. Please keep in mind that isolated areas within each snowfall range might have slightly less or more than is stated in the graphic; these ranges were based on the overall amounts we received from each site.
