Light snow developed over southern Wisconsin Friday morning ahead of a cold front. The snow persisted through the mid-afternoon in most areas due to the assistance of an approaching upper level disturbance. Moderate to heavy snowfall occurred east of Madison and along the cold front as it moved through in the morning and with a distinct band of snow that passed through in the early afternoon. Blustery north winds that moved in behind the cold front led to blowing snow and reduced visibilities.
Behind the front, an arctic air mass moved into the area, bringing much cooler temperatures for the weekend. Low temperatures will drop down into the single digits Friday and Saturday night and high temperatures will only reach the mid to upper teens Saturday and the mid to upper 20s Sunday. In addition to much cooler temperatures, blustery northwest to west winds will make temperatures feel 10 to 20 degrees cooler.
