The snow began moving into western Wisconsin around daybreak and will spread eastward, exiting the state from west to east late in the day, the National Weather Service said.

Far southern Wisconsin will get little to no snow and more rain due to temperatures being above freezing for all or much of the storm’s duration.

Predicted snow totals include 4 to 6 inches for Wisconsin Dells, Tomah, Richland Center and Viroqua; 3 to 5 inches in Portage; 3 to 4 inches in La Crosse and Green Bay; 1 to 3 inches in Madison; up to 1.5 inches in Eau Claire; up to an inch in Janesville; and up to a half-inch in Racine and Dubuque, Iowa.
