|Episode Narrative||A very amplified weather pattern developed across the central U.S. the latter part of December, which produced nearly 48 hours of wintry precipitation across the Upper Midwest starting the evening of December 23th.
Prior to the 23th of December, areas of light snow and light freezing drizzle occurred across the region, which caused the issuance of several winter weather advisories prior to the winter storm that developed late Wednesday afternoon.
Two storm systems began to organize across the central Plains and northern Rockies on Wednesday December 23th. The southern system caused a large shield of precipitation to develop across the Plains and Midwest, which moved northward into southern Minnesota and west-central Wisconsin the afternoon of December 23th. Several bands of heavy snow began to develop across southern Minnesota during the evening, which moved into west-central Wisconsin prior to midnight.
There was a break in the precipitation late Wednesday night and early Thursday before the next storm system began to affect the Upper Midwest late Thursday afternoon and evening. However, this system was much warmer and caused the precipitation to switch to sleet and freezing rain across west-central Wisconsin the evening of December 24th. Temperatures continued to rise during the overnight period of December 24th/25th, which caused the sleet and freezing rain to switch over to light rain. By the time the large storm system exited the Great Lakes, between 3 and 12 inches of snow fell across the warned area, with slightly lesser amounts where sleet, freezing rain and rain were predominate.
Some of the higher snowfall totals include: 12 inches in Bruce, 10 inches at Rice Lake and Chetek, and 8 inches in Connorsville.
|Event Narrative||Three storm systems affected Rusk County over a period of 48 to 60 hours. However, the majority of the snow fell before the morning of the 25th. A mixture of sleet, snow and some freezing rain kept total snowfall amounts of 6 to 10 inches across the county. However, one observer measured 12 inches in the town of Bruce.|
