The episode as NWS GRB wrote it up.
A complex storm system affected the region November 10-11, 2014, bringing a swath of heavy snow to parts of northern Wisconsin. The main storm hit in two phases. The first phase was in the form of a long west to east band of snow which set up across Minnesota and northern Wisconsin early on November 10th. Low pressure then moved across far southern Wisconsin and produced another round of snow late on November 10th and into the 11th across central and northern Wisconsin.
In addition to the long-duration storm, additional lake effect snow from Lake Superior pushed totals over 20 inches in some locations in the snowbelt. The highest reported snowfall total was 23.7 inches at Lac du Flambeau (Vilas Co.). Some of the highest snow totals outside the snowbelt included 15.2 inches near Alvin (Forest Co.), 12.5 inches at Florence (Florence Co.), 12.0 inches at Lake Tomahawk (Oneida Co.), and 11 inches at Pearson (Langlade Co.).
