Winter Storm — Dane, Wisconsin

2007-02-23 to 2007-02-24 · Dane, Wisconsin

Wider weather episode

A winter storm (first of two rounds) consisting of heavy snow with some sleet and freezing rain mixed in, left behind 6 to 8.5 inches of accumulations over several south-central and southeast Wisconsin counties. Additionally, there were frequent wind gusts to around 25 mph which resulted in a fair amount of blowing and drifing of the new snow. The greatest snow accumulatins occurred north of a line from Madison (Dane Co.) to Brown Deer (Miwaukee Co.). Maximum amounts in each affected county include 8 inches in Brown Deer, just over 6 inches in extreme northwest Waukesha County, 7.5 inches near Lake Mills (Jefferson Co.), 8.3 inches south of Middleton (Dane Co.), 8.5 inches in Saukville (Ozaukee Co.), 7.7 inches northwest of Beaver Dam (Dodge Co.), 8 inches in the Wisconsin Dells area (Columbia Co.), 8 inches in the Lake Delton area (Sauk Co.), 7.4 inches near Oxford (Marquette Co.), 8.5 inches between Berlin and Green Lake (Green Lake Co.), 8 inches just west of Ripon (Fond du Lac Co.), and about 6.5 inches in extreme southwest Sheboygan County. A 34-year-old man died (indirectly-related) in a vehicle accident on a slippery road in the Town of Springfield (Dane Co.) Friday night. The roof of an abandoned building in McFarland (Dane Co.) collapsed Friday night due to the weight of the heavy, wet snow.

Synoptically, this winter storm was the result of a strong upper-level short wave trough moving northeast through Wisconsin with plenty of warm-air advection and moisture advection in the low to mid levels of the atmosphere. Some rumbles of thunder were reported as well. Lesser amounts of snow, in the 3 to less than 6 inch range, fell near the Illinois border. Further northwest in the La Crosse area, 12 to 14 inches of snow were measured.
