One of the biggest winter storms in years pounded much of Wisconsin, including the northeast part of the state. Widespread snowfalls of 8 to 16 inches were reported across much of northeast, east-central and central Wisconsin. Some of the highest totals included 16.5" in Allouez and Ledgeview (east of De Pere), 16.2" on Green Bay's east side, 16.0" in Wautoma, and 15.5" at St. Nazianz in Manitowoc County. Officially, 14.7" fell in Green Bay (NWS office).
The snow developed as low pressure rapidly deepened (what meteorologists call a "bomb") as it moved across Illinois into Lake Michigan. Strong winds in response to the deepening low created blowing snow and near blizzard conditions late Tuesday night across parts of northeast Wisconsin. Winds gusted to over 50 mph in Door County, and to 48 mph at the NWS Green Bay office.
The 14.7 inches in Green Bay places this storm in the top 6 biggest snowstorms in Green Bay weather history (observations since 1886), and is the biggest December snowstorm ever.
Here are preliminary snowfall (through mid-day Wednesday) and wind gust maps:
