An early Winter storm system brought just about every type of winter precipitation to the area from December 1st into the 2nd: snow, sleet, freezing rain and rain. In addition, strong wind gusts from 35 to 40 mph managed to drift some of the heavy snow that fell.

Snow was the dominant precipitation type from around the Interstate 90 corridor northward, with generally a wintry mix to just rain south of there. The heavy snow came in two waves: one during Saturday morning (Dec 1), impacting mainly southern Minnesota, with the second wave coming in during the evening Saturday night (and into early Sunday), centered on Interstate 90.  Inch per hour snowfall rates were common in these bands, with visibilities under 1/2 mile at times. 

In addition to a swath of 6 to 10 inches of snow, there was ice accumulation on and off through the day and night - generally a trace to under 1/10 of an inch.
