December 1st Winter Storm Map and Summary

A strong push of relatively warm and moist air surged across southern Wisconsin on Saturday, December 1.  Snow, heavy at times, spread into south central Wisconsin Saturday morning, and across the rest of southern Wisconsin by early afternoon.

Snowfall of 1 to 4 inches rapidly accumulated south of I-94 with 4 to 7 inches north of I-94 for several hours following the onset of the snow, resulting in deteriorating travel conditions.  As the warm air continued to surge into the region, the snow changed to a mixture of sleet and freezing rain.  An inch or two of sloppy, wet sleet piled up on top of the newly fallen snow.  Between one tenth and one half of an inch of freezing rain caused ice accretion on many surfaces including trees and power lines. 

To add to the misery, strong southeast winds gusting as high as 45 mph caused ice coated tree branches to fall onto power lines resulting in sporadic power outages.

The snow, sleet and freezing rain diminished from southwest to northeast during the late afternoon and evening across southern Wisconsin as temperatures warmed to slightly above freezing.

Here are some of the heavier snow and sleet accumulations reported to the National Weather Service office in Sullivan:
