Much of Wisconsin is under a winter storm warning, as another round of snow sweeps through the state and temperatures plummet to risky levels. Wind chills values between 25 and 40 degrees below zero are expected. Expect a slight warm up during the snowstorm.
And while the weather during the early part of the day tomorrow is expected to be cold, but calm, it will be short lived, as a low-pressure system makes it way toward the area Friday evening, bringing with it a predicted 5 to 10 inches of snow Friday night and Saturday. A winter storm watch means there is potential for significant snow, sleet or ice accumulations that could affect travel.
Paige said DOT officials are working with the National Weather Service, Wisconsin State Patrol and other state and local entities in preparation for what could be slick and unsafe roads. Wind chill temperatures will fall to 2o to 30 below zero by Sunday morning, with similar lows Monday morning.
Highs on Sunday may again remain below zero with risky wind chills during the day.
The agency has issued a wind chill advisory for the region that expires at noon Saturday.
The real snow event won't start until Friday afternoon. "The winds should be leading to fairly significant blowing and drifting.so, especially, your east-west roadways should be impacted fairly significantly with the northwest winds". While the map above shows 6 to 7 in those areas, they could be between 6 to 8 inches of snow. At the forecast wind chills, frostbite can happen to exposed skin within 30 minutes.
Friday's low in Madison was 7 at 6:30 a.m., 9 degrees below the normal low and 25 degrees above the record low of 18 below for December 16, set in 1876.
