12z European Ensemble model 12-2-2018
A warm signal showing up the week of December 9 with the greatest departures from normal covering much of Canada, but still looks plenty warm for the northern Plains, upper Midwest and Great Lakes as well. Cooler than average temps for the southern U.S. More or less a classic El Nino type pattern setting up after this week, but for how long? At least some of the long range computer models show a flip to a colder pattern again later this month.
Note: Normal temperatures for the Northland from Dec 10-15 are generally in the low 20s with normal lows mainly in the single digits — Could be looking at daytime highs well into the 30s, maybe some 40s with overnight lows in the 20s. Record warmth or a top 5 highest max or min temp is certainly possible for some locations in the Northland from Dec 10 to 15 per model data.

Weather Synopsis for Northeast Minnesota and Northwest Wisconsin
Another overcast day with gusty northerly winds. Low pressure has moved into the eastern Great Lakes this afternoon with high pressure to our northwest, flow between the low and high continues to be out of the north across our area today with weak cold air advection occurring over the upper Midwest. Highs today not bad for early December, ranging from the mid 20s to low 30s, pretty much what our normal highs are for December 2, but with the clouds and gusty winds, it didn’t feel too nice outside.
The low to our SE continued to bring some light system snow and lake enhanced snow to the South Shore and other areas of northwest Wisconsin today, while it was mainly dry in northern Minnesota.
Snow to continue tonight across portions of northwest Wisconsin with the heavier snowfall most likely along the South Shore, including northern parts of Bayfield, Ashland and Iron counties where another 2 to 4 inches of snow could accumulate tonight. The remainder of our area should be dry tonight. Mostly cloudy skies, few breaks in the clouds could develop later on. Lows in the teens and 20s with single digits possible in northern Minnesota if skies clear enough.
High pressure settles into the upper Midwest for Monday, and this might be enough to help produce some much needed sunshine at least for some of us, but overall it still looks like a mostly cloudy or partly sunny kind of day. Highs Monday in the 20s.
Keeping an eye on a midweek system which could bring a brief burst of snow to the area but it doesn’t look like it would be a lot of snow.
