Rounds of freezing rain and brief periods of sleet affected southern WI for greater than a 24 hour period as low pressure slowly approached the western Great Lakes from the central Great Plains. Although surface air temperatures were above freezing at times, the pavement temperatures were at or below freezing creating icy and hazardous traveling and walking conditions. A large number of schools were closed or delayed for both days. Numerous vehicle slide-offs and accidents occurred including a 30 to 40 vehicle pile-up in Dane County.
