Forecast Discussion for Northeast Minnesota and Northwest Wisconsin
Short Term Forecast – Confidence: High.
Tonight (November 30)
Partly to mostly cloudy skies will be common Tonight with patchy light freezing drizzle possible along with a few snow showers along the South Shore of Lake Superior. Snowfall accumulations should remain on the light side and generally around an inch or less Tonight along the South Shore. Lows will be in the teens and 20s with northerly winds at 5 to 15 mph.
Sunday and Sunday Night (December 1)
Lake effect snow showers are possible at times near Lake Superior and as low level winds veer from north to east, this will shift the focus for any lake effect snow to the North Shore, generally northeast of Duluth. 1-2″ of snow could accumulate during this period from Two Harbors – Silver Bay – Tofte – and Grand Marais and slightly inland along the Higher Terrain. The remainder of the area will have partly to mostly cloudy skies. Highs will be in the 20s and 30s with lows in the teens and 20s. Winds will shift to the east at 5 to 15 mph.
Extended Forecast – Confidence: Medium to High.
Monday through Wednesday (December 2-4)
Looks like were in store for a rather active weather week over the Upper Midwest as a large upper level trough approaches from the west while a southwest flow aloft pulls milder/moist air north from the Gulf Of Mexico. Low pressure will be moving into the Rockies/Western High Plains/Northern Plains region Monday and Tuesday, this low is then forecast to pull into the Upper Midwest by mid-week the way it looks now.
Periods of snow are expected in NE Minnesota and NW Wisconsin beginning on Monday and continuing through Wednesday. It’s certainly possible that there will be heavy bursts of snow at some point especially between Tuesday and Wednesday.
Easterly flow coming off Lake Superior may also lead to lake enhanced snow along the North Shore of Lake Superior during this period.
Temperatures both at the surface and aloft could warm up enough resulting in a snow, rain, or an icy mixture from Tuesday into Wednesday…Right now Northwest Wisconsin and possibly Eastern Minnesota would have the greatest chance to see this possible winter mix of precipitation.
High temperatures from Monday through Wednesday will be in the 20s and 30s with lows Monday Night and Tuesday Night in the 20s.
Long Range Forecast – Confidence: Medium to High.
(December 5-10)
Some snow could linger into Thursday (5th) depending on how things setup. The rest of this period looks generally dry, although recent long range models suggest that some additional snow could fall over parts of the Northland from the 6th-8th. Something to keep an eye on. Below average temperatures are forecast through this period.
*7-day precipitation forecast from the Weather Prediction Center. This is valid thru Saturday, December 7, 2013. Hefty QPF amounts showing up over all of the Northland. 0.75″-1.25″ liquid equivalent amounts. If this were to fall entirely as snow, then will likely see widespread 10-12″+ totals from North Dakota through Northern Minnesota and Northwest Wisconsin. Stay tuned!
