COPY-Winter storm expected on Sunday

A winter storm is forecast to impact much of Wisconsin on Sunday. 

In advance of the storm's arrival, the National Weather Service has issued a Winter Storm Warning for Adams, Clark and Juneau Counties from 9 a.m. to midnight on Sunday. 

A Winter Weather Advisory will be active for Marathon, Wood, Portage, Taylor, Lincoln, Langlade, Shawano, Waupaca and Waushara Counties from 9 a.m. to midnight on Sunday.  

This winter storm will be moving toward the region from the southwest.  That will pull warmer air into the area and provide the possibility of the storm dropping a mix of freezing rain, sleet, rain and accumulating snowfall through Sunday afternoon and evening.  

Most locations in the Newsline 9 viewing area can expect to see the storm begin with snow late Sunday morning through Sunday afternoon.  By Sunday evening however, warmer air aloft will surge northward from a warm front.  That brings in the opportunity for freezing rain and sleet to develop.  

Since the storm is not forecast to only bring snow, but a wintry mix of precipitation, snowfall accumulations are difficult to project.  A lot hinges upon how far north the warm front is able to push and how long into the day snow is able to fall.  Given the storm's projected track,  between 2 and 4" of snow is currently forecast over much of Marathon, Wood and Portage Counties by Sunday evening.  North of Wausau accumulations between 1 and 3" are expected.  

South of Wood and Portage Counties the chance of seeing accumulating ice becomes more likely.  That will significantly cut back on snowfall totals with the storm.  

Current snowfall projections place under 3" of snow south of Adams and Juneau County.  However, ice accumulations could build up near .25" by Sunday night.

With a swath of wintry mix precipitation moving over the state, motorists should use caution when driving on Sunday afternoon and evening.  Though the brunt of the storm is expected to be east of Wisconsin by daybreak on Monday, it is very possible slick roadways could still exist during the Monday morning commute hours.
