Episode Narrative Winter Storm conditions were experienced in the Baraboo to Madison to Milwaukee corridor from the evening hours of Dec 23rd into the early morning hours of Dec 24th. This storm had a major impact on Holidy shoppers and travelers due to slippery roads and poor visibibilities. Generally, a band of moderate, to at times heavy snow, extended from near Milwaukee to just north of Madison to the Wisconsin Dells area, producing 2 to around 6 inches of accumulation before changing over to sleet and freezing rain overnight. Ice accumulations were on the order of 1/10 to 2/10 of an inch, but there was an isolated 1/4 inch ice accumulation in south-central Dodge County. Small tree branches broke under the weight of the snow and freezing drizzle, but no power outages were noted. The maximum snow accumulations for each county included 6.3 south of the city of Waukesha, almost 6 inches in far northwestern Sauk County, 5.5 near Port Washington (Ozaukee Co.), 4.4 in Big Bend (Waukesha Co.), 4.2 in Downtown Milwaukee, 4.1 just southeast of Portage (Columbia Co.), 4 in Hartford (Washington Co.), 3.8 in Lake Mills (Jefferson Co.), 3.5 in the southwest part of the city of Madison, 3 in southeast Dodge County, and 2 in east-central Iowa County. Synoptically, warm air advection with a short wave aloft followed by a surface low pressure lifting northward from the southern Plains brought a mix of snow, sleet and freezing rain to southern Wisconsin the afternoon of Wednesday, December 23rd into the morning of Thursday, December 24th. Toward the Illinois border, mostly freezing rain fell that resulted in a low-end ice storm.
