Forecasters: Storm could bring 4 to 7 inches of snow
JANESVILLE—Weather forecasters have scaled back snowfall totals expected in a storm that will hit late Saturday and linger through Sunday, but the area remains under a winter storm warning through Sunday morning.
Rudy Schaar, a meteorologist at the National Weather Service's Sullivan office, said updated forecasts show predicted a winter storm overnight and into Sunday that could bring 4 to 7 inches of wet, heavy snow.
Earlier forecasts indicated that some areas of Rock and Walworth counties could see 8 to 10 inches of snow, but Schaar said the center of a large band of snow has begun to track further north than initially forecast.
That means slightly less snow in Rock and Walworth counties, although Schaar said continued freezing rain is expected to fall throughout the evening Saturday.
He said the rain will turn to heavy, wet snow late Saturday and continue throughout the night as temperatures hover just below freezing.
Snowfall accumulations early Sunday could total 4 inches, with another 2 to 3 inches of snow expected to fall into Sunday morning, according to the National Weather Service.
Schaar said snowfalls could total an inch or more an hour overnight, and winds could pick up to 15 miles per hour. While drifting will likely be minor, Schaar said people traveling should expect visibility to be poor throughout the night.
Road conditions are expected to be sloppy as freezing rain and snow accumulates on already icy roads. The city of Janesville has declared a snow emergency effective 6 a.m. Sunday. That means people should park their vehicles off roadways until the city is able to clear snow to the curb.
Travelers should expect heavier snowfalls to the north in a band of snow that extends northeast from southern Wisconsin to Green Bay, Schaar said. Snows further north are expected to total 8 to 10 inches, according the National Weather Service.
