What happened
The episode as NWS GRB wrote it up.
Low pressure moved across central Illinois from Iowa and produced a large swath of snow across Wisconsin. Northeast winds, that frequently gusted to 25 mph, brought cold air over the warmer waters of Lake Michigan resulting in enhanced heavy snowfall in parts of east-central Wisconsin. At the height of the storm, snow and blowing snow caused traffic on Interstate 43 in Manitowoc County to be reduced to one lane.
The highest snowfall totals during the storm included 12.0 inches at Kiel (Manitowoc Co.), 8.5 inches at New Holstein (Calumet Co.) and 8.4 inches near Manitowoc (Manitowoc Co.).
