Temperatures will drop big time tonight and the winds out of the northwest at 15-25mph will make it feel like around -35 to -45. Actual lows will dip down to the upper single digits below zero from -5 to -10 for most of the region. Expect some lingering snow showers for the South Shore and U.P. The NW flow will supply moisture, but the wind is so strong that it could inhibit lake effect. So we might be dealing with lake enhanced snow, which will lead to lesser totals. Expect an additional 2-4” tonight east of Ashland.
Snow showers continue for the Upper Peninsula Friday, Winds continue out of the northwest at 15-25mph. Gogebic County can expect another 2-4” of snow out of these bands. The rest of the region, all of NW Wisconsin, and NE Minnesota gets sun as high pressure pushes into the southwest corner of Minnesota. It’s cold, with highs near 1.
The high pressure system sits over Wisconsin and keeps skies clear and calms our winds down. Low temps will get down to around -15 to -25.
Saturday an upper level disturbance will swing over the area and bring a small chance of snow to areas north of Duluth. There’s also a high to our north and a high to our south, which will cause convergence at the surface of the earth here in the Northland creating clouds and the chance of some flurries. I’m going to include a 20% chance for Duluth. High temperatures will be in the upper single digits.
Sunday morning a high pressure system starts to move in from the northwest. This allows us to clear up a bit by the afternoon. Lows are down to -3 and highs reach 14. Monday our high pressure system move just north of Lake Ontario supplying us with a southern wind that warms our temps a bit. Low temps are around 2 and highs reach the upper teens.
Tuesday a low pressure system rides north and east to the Chicago/Madison area. This increases our snow chances to 70%. Expect snow showers in the early morning and snow to taper off by Wednesday morning. Right now it looks to be in the 3-6” ballpark but we all know that could and probably will change.
