The largest winter storm in nearly two years affected much of Wisconsin with wet, heavy snow. Snowfalls of 8 to 12 inches fell across the central and northeast part of the state.  The snow developed from low pressure which moved out of the southern Plains and into northeast Illinois. Strong winds in response to the deepening low gusted over 30 mph at times, but blowing snow was limited by the high water content.
Some of the highest snowfall totals included 12.2 inches at Oshkosh (Winnebago Co.), 11.9 inches in Mosinee (Marathon Co.), 11.7 inches at Neenah (Winnebago Co.),  11.0 inches at Wisconsin Rapids (Wood Co.), 10.8 inches near Big Falls (Waupaca Co.), 10.6 inches at Coloma (Waushara Co.), 10.5 inches at Oconto (Oconto Co.) and Appleton (Outagamie Co.), 10.2 inches near Amherst (Portage Co.) and 10.1 inches at Green Bay (Brown Co.).
The highest wind gusts during the storm included 45 mph at Green Bay, 41 mph at Marshfield (Wood Co.), 39 mph at Oshkosh and near Combined Locks (Outagamie Co.) and 38 mph at Manitowoc (Manitowoc Co.) and near Kimberly (Outagamie Co.).
