Overview

Snow spread into the area during the afternoon hours on Saturday, December 10th, continuing into the afternoon hours of the following day (Dec.11th). An enhanced band of snowfall developed around the Interstate 90 corridor late Saturday evening, and would gradually shift northeast to Interstate 94 early Sunday morning.

Snowfall rates of up to 1" per hour were common in this band. The snow was light and fluffy, but winds were not that strong keeping impact lower - mainly because of snow covered roads.
