Several Inches of Snow Expected Tomorrow
It has not even been a full week an we are already talking about our next snow system to impact the Northland this early in the season. Another Alberta Clipper is diving down from Canada as we speak bringing snowfall to the higher elevations of the Rockies. Some areas could see over a foot by tomorrow afternoon.
As for us, snowfall will begin by the morning. Right now we anticipate snow to begin from Aitkin to Koochiching County around 6-7 AM and then move into the rest of Northeast Minnesota by 11 AM. Snowfall will start light at first but will ramp up in intensity by the late morning into the early afternoon.
A winter storm warning is in effect for the North Shore in Northeast Minnesota, specifically for Lake and Cook County lakeshore areas. A winter weather advisory is in effect for the rest of the Northland excluding Gogebic County.
Winds will be coming out of the east and southeast. These winds will be grabbing moisture from the warm waters of Lake Superior and then get forced up the hillside by orographic forcing as the hillside acts like a wall forcing the air up to the moist where it will add more moisture to the ongoing snowfall and enhance the intensity.
The heaviest snowfall will happen during the afternoon. Snowfall intensity and coverage will diminish later in the evening hours as the storm moves through. The highest totals will be along the North Shore with the likelihood of 4 to 8 inches. Along and Norther of Minnesota 1 from Ely to Bigfork, 1 to 3 inches are likely. Then the rest of Northeast Minnesota will see 2-4 inches with some isolated higher amounts.
In Northwest Wisconsin, all areas should see 2-4 inches except the northern half of Ashland, Iron, and Gogebic County where only an inch could perhaps fall along the lakeshore.
After tomorrows snow maker, the next chance of snow will come on Friday night into Saturday morning where an additional few inches of snow will fall ahead of a warm front which will pass the Northland later Saturday evening. Temperatures will rise into the 40s so the snow that falls will likely melt by Sunday.
