Weather Summary for NE Minnesota and NW Wisconsin
Date:  April 7, 2016

One strong upper level low and surface low is lifting north/northeast through the eastern Great Lakes into eastern Ontario Province while upstream another system is intensifying as it digs south/southeast out of eastern Manitoba Province this afternoon.  Generally mostly cloudy skies across the Northland today with some showers of snow and rain in spots.  Highs were mainly in the 30s with winds out of the west, north or east at 5 to 15 mph.

Forecast Discussion for NE Minnesota and NW Wisconsin

Short Term Forecast - Confidence:  High.

Tonight (April 7)

Snow returns to northeast Minnesota and northwest Wisconsin as a strong upper level system digs into the Upper Midwest, some of the snow could be heavy at times before midnight from the Iron Range down toward the Twin Ports and in far northwest Wisconsin with a potential for heavier snow showers continuing past midnight over the Arrowhead of Minnesota.  Low temperatures will be in the teens and 20s as winds shift to the northwest and increase to 15 to 30 mph.

Friday and Friday night (April 8)

A trough will linger near Lake Superior tomorrow which will result in more snow showers around the lake -- Convergence should be greatest over the Arrowhead and this will be one spot for locally heavy snow showers tomorrow -- The other spot will be along the South Shore of Lake Superior where heavy lake effect snow showers are expected thanks to a favorable N-NW wind direction and lots of cold air moving over Lake Superior.  The remainder of the Northland should be mainly dry on Friday with just a few snow showers or flurries possible.  Highs tomorrow will be in the 20s and 30s with northwest winds at 15 to 30 mph.

Lake effect snow showers persist Friday night along the South Shore of Lake Superior, dry elsewhere as high pressure settles into the Upper Midwest.  Lows will be in the single digits below to teens above zero with north or northwest winds at 10 to 20 mph.

Extended Forecast - Confidence:  Medium to High.

Saturday through Monday (April 9-11)

Dry on Saturday as high pressure moves east of the Upper Midwest, this will allow the next system to move in from late Saturday night through Monday.  Not a lot of precipitation with this next low and what does fall should be fairly light.  Looking at a possible light snow or mixed precipitation event in parts of the Northland late Saturday night through Sunday morning with a chance for snow showers and flurries from Sunday night through Monday.

Temperatures on Saturday will be in the 20s and 30s.  Highs on Sunday will range from the 30s in far northern Minnesota and near Lake Superior to the 40s and 50s elsewhere.  Lows Sunday night will be in the 20s.  Highs on Monday will be in the 30s.

Long Range Forecast - Confidence:  Medium to High.

(April 12-17)

Below average temperatures continue on the 12th but after that were looking at near to possibly above average temperatures from the 13th-17th.  Note:  Normal high temperatures for mid April are generally in the 40s to around 50 degrees.  There is a chance that high temperatures top 50 degrees, maybe even 60 degrees sometime late next week or next weekend.  Looks mainly dry during the long range although a system developing over the Rockies will have to be watched as it could bring some rain to the Upper Midwest during the 14th-17th time frame.
