MADISON, Wis. (WMTV) If you have been following along this month, we have been talking about a pattern shift to colder and snowier by the end of January. That transition looks to take place as we move into the weekend with our next weathermaker.
A major Winter storm will impact areas from the Midwest, Great Lakes, and to the East Coast by early next week. In its wake, a large swath of accumulating snowfall. While we will once again by on the northern fringe of this system, we will be close enough this time to get accumulating snow. Winter weather alerts have been posted for southern Wisconsin.
A tight accumulation gradient will be present across southern Wisconsin with totals of 1-8 inches by midday Saturday. Heaviest totals will be along the stateline with accumulations tapering off dramatically as you move to the north.. A large chunk of the area will be between 3-5 inches. With such a tight gradient, minor adjustments to the forecast are likely through Friday as new data comes in.
Clouds will move in Friday morning with snow developing by the afternoon and evening. Steady, heavy at times, snow will continue Friday night into early Saturday before tapering off by Saturday afternoon. In its wake, breezy conditions and lake effect snow showers will remain. The coldest air of the season will arrive by Sunday with highs into the teens, lows in the single digits, and wind chills below zero.
