What happened

The episode as NWS MKX wrote it up.

Low pressure moving northeast through southern Illinois and southern Indiana generated a long-duration winter weather snow event over southeastern Wisconsin. North to northwest winds gusting to around 17 to 22 knots (20 to 25 mph) generated some blowing and drifting snow, especially in open areas. This event wasn't logged as a Heavy Snow event due to the needed 8 threshold for 24 hour systems. Several airline flights at Milwaukee Mitchell Field were delayed or canceled, and several civic functions were canceled. At the tail end of the snow event, lake-effect enhancement was responsible for 1 to 2 inch accumulations near Lake Michigan. Total snow accumulations include 7.5 at 3NW Milwaukee, 7.2 at Paddock Lake, 7 at Port Washington and 4SW Somers, 6.5 at Union Grove and Whitewater, 6.4 at Milwaukee Mitchell Field, 6 in Muskego, 5.2 at Random Lake, 5.1 in Richfield, 4.9 at the NWS office southeast of Sullivan, 4.5 at Beloit, 3.5 at Brodhead and Johnson Creek, 3 to 3.5 in southeastern Dane County, and about 4 in southeast Dodge County. The snow of December 15-16th ultimately led to building damage in Jefferson County. In the early morning hours of December 18th, a section of the roof and two supporting beams collapsed at the Johnson Creek Junior and Senior High School due to the weight of accummulated snow and ice. No one was injured.
