The second significant winter storm/ice storm to affect south-central and southeast Wisconsin in December, 2007, struck on December 11-12th (December 1st was the other one).  It generated a mix of snow, sleet, and freezing rain, however, freezing rain was the primary precipiation type in the counties of Waukesha, Milwaukee, Green, Rock, Walworth, Racine, and Kenosha.  Ice accumulations of around 1/2 inch occrred near and south of a line from Beloit to Lake Geneva to Kenosha.  The northern extent of 1/4 inch ice accumulations extended along a line from Browntown in far southwest Green County to Milton to Palmyra to Mukwonago to Milwaukee.  The far northern extent of any freezing rain was along a line from Darlington to Middleton to Juneau to Port Washington.  Sleet accumulations of 1 to 2 inches occurrred mostly in a 15-mile wide band extending from around Shullsburg to Monticello to Whitewater to New Berlin to Milwuakee.  Snow accumulations of 1 to almost 8 inches were reported just north of the sleet band.  There was some overlapping of precipitation types.
Numerous airline flights and civic functions were canceled before the start of the winter storm/ice storm.  Numerous minor vehicle accidents were reported in newspapers.  The roofs of two small metal sheds in Green County collapsed due to the weight of the snow and ice accumulations during December, 2007.  One was located about 5 miles west of New Glarus, and the other about 7 miles northwest of Monroe.
