Winter Weather — Rock, Wisconsin

2007-12-04 to 2007-12-05 · Rock, Wisconsin

Wider weather episode

An Alberta-Clipper low pressure tracked from South Dakota, to Iowa, to southern Illinois, to southern Indiana from the morning of Tuesday, December 4 to the early morning on Wednesday, December 5. Widespread light to moderate snow to the north of this track produced a general 3 to 6 inches across south-central and southeast Wisconsin. There were a couple isolated spots with 7 to 9 inches. The wind was a non-factor, snow plow crews were able to keep up with the accumulations, and there was minimal impact on society. Consequently, this system was not classified as a heavy snow event. Lake-effect enhancement resulted in higher totals in Racine and Kensoha Counties (see Heavy Snow event for these counties). Excessive speed was a factor in a 2-vehcile accident south of Janesville on Interstate-39/90 which resulted in one indirect death and one indirect injury. A portion of a roof of a business near Hustiford collapsed due to the weight of accumulated snow and ice. No one was injured.

Specific snow totals include 9 at Mt. Horeb, 7.8 at Milwaukee Mitchell Field, 7.7 on the southwest side of Madison, 6.6 at Beaver Dam, 6.2 at Cedarburg and Baraboo, 6.1 at Eagle, 6 at Lodi and Ft. Atkinson, 5.8 at Genoa City, 5.5 at Monroe and Argyle, 5.4 at Oxford, 5 at Germantown, Barneveld, and Janesville, 4.5 at Markesan, 4 in far southwestern Fond du Lac County, and 2.5 in the Random Lake area. for the calendar day of December 4th, the 4.2 measured at Milwaukee broke the old record of 3.3 set in 1964. Likewise, Madison's 5.6 on December 4th broke the old record of 5.5 set back in 1897.
