Weather Summary for NE Minnesota and NW Wisconsin
Date:  February 9, 2016

Yes it was cold today but it sure looked and felt nice with all that sun.  Most of the Northland had sunny or partly cloudy skies today but lake effect clouds and snow showers continued along the South Shore of Lake Superior mainly affecting Bayfield, Ashland and Iron Counties.  Highs today were in the single digits and teens with northwesterly winds at 10 to 20 mph.

Surface map late this afternoon had low pressure of 998-1000mb over Southeast Ontario Province with high pressure of 1030mb centered in Manitoba Province.  The upper level pattern featured a very strong ridge (582 meters) over the Western U.S. with record heat for the second day in a row extending from British Columbia and Alberta in Southwest Canada down into the Southwest U.S. Temperatures in the 50s and 60s as far north as Montana this afternoon with 80s and even some 90s in parts of California! But this ridge to our west is also allowing a deep trough to form east of the Rockies with 500mb heights of 516-522 meters in place over much of Central/Eastern Canada into the Northeast U.S.

Forecast Discussion for NE Minnesota and NW Wisconsin

Short Term Forecast - Confidence:  High.

Tonight (February 9)

Clear to partly cloudy skies.  Colder than last night as low temperatures drop into the single digits, teens and 20s below with the typical cold spots possibly dipping to around 30 below.  Scattered lake effect snow showers will continue tonight along the South Shore of Lake Superior mainly over Ashland and Iron Counties.  Winds will be out of the north or northwest at 5 to 15 mph.

Wednesday and Wednesday night (February 10)

A clipper dives southeast across the Northern Plains but will remain to our southwest so the snow associated with this system will miss the Northland.  Partly to mostly sunny skies tomorrow and clear to partly cloudy skies tomorrow night.  Still cold with highs ranging from around zero to the teens with lows in the single digits and teens below to single digits above zero.  Winds will remain out of the north or northwest at 10 to 15 mph so a few lake effect snow showers will be possible on Wednesday along the South Shore of Lake Superior in Northwest Wisconsin thanks to that NNW wind coming off Lake Superior.

Extended Forecast - Confidence:  High.

Thursday through Saturday (February 11-13)

Mainly dry and cold from Thursday through Saturday.  Highs Thursday will be in the single digits and teens with lows Thursday night in the single digits below to single digits above zero.  Friday and Saturday's high temperatures will be in the single digits below to single digits above zero with lows Friday night in the single digits, teens and 20s below with 30s below even possible in Northern Minnesota.  Wind direction will shift back to the NNW for Friday and Saturday which will result in a chance for some lake effect snow once again along the South Shore of Lake Superior in Northwest Wisconsin.

Long Range Forecast - Confidence:  Medium.

(February 14-19)

Below average temperatures continue on the 14th which will be followed by near to above average temperatures from the 15th-19th.  No major storms showing up that would affect the Northland during the long range but a minor snow event or two is possible - One on the 14th-15th, and possibly another on the 16th.
