Today's Weather Summary for NE Minnesota and NW Wisconsin

Low pressure of 1002mb was over Southeast Ontario with arctic high pressure of 1032mb over Southern South Dakota.  Partly to mostly cloudy skies were common in parts of Northwest Wisconsin while clouds earlier in the day gave way to quite a bit of Afternoon sunshine in Northern-Eastern Minnesota.  Scattered snow showers and flurries occurred Today mainly along the South Shore of Lake Superior.  Frigid temperatures were the main weather story Today with highs only in the single digits and teens below zero with mid-Afternoon wind chills in the teens and 20s below.  Winds Today were out of the northwest at 5 to 15 mph.

Forecast Discussion for NE Minnesota and NW Wisconsin

Short Term Forecast - Confidence:  High.

Tonight (December 29)

Clear to partly cloudy skies will be found in our area Tonight as high pressure moves over the Upper Midwest.  Low temperatures will be in the teens, 20s, and 30s below with winds out of the west or south at around 10 mph.

Monday and Monday Night (December 30)

Cold temperatures will continue.  A weak system will drop southeast out of the Northern Plains and will bring some light snow or flurries to parts of the Northland Tomorrow and early Tomorrow Night.  At the moment it looks like most of the light snow would fall along and south of Highway 2.  Not expecting much accumulation with all the cold/dry air in place.  Probably only a dusting to a half inch from Cass Lake and Brainerd toward the Twin Ports, I-35 corridor and in most of Northwest Wisconsin.  Most of Monday Night should be dry after some early Evening flakes.

High temperatures will be in the single digits below to single digits above zero with lows in the single digits, teens, and 20s below.  Winds will be out of the south or west Tomorrow at 5 to 15 mph.  Winds Tomorrow Night will be out of the northwest at 5 to 15 mph.

Extended Forecast - Confidence:  High.

Tuesday through Thursday (December 31-January 2)

Arctic air will continue to grip the Northland during this period as the Polar Vortex covers Hudson Bay and much of Eastern Canada.  This will keep our area locked in a NW flow aloft which will help keep the much below average temperatures in place.

There will be a snow event that'll affect areas south/southeast of the Northland from Tuesday Night through early Thursday, but right now it looks like all the accumulating snow will stay away from our area, but the exception to that may be along the South Shore of Lake Superior where north winds could result in an increase in lake effect snow from Wednesday into Thursday.

High temperatures on Tuesday will be in the single digits and teens below with lows in the teens and 20s below with a few 30s below possible in Northern Minnesota.  Highs on Wednesday will be in the single digits below to teens above zero with lows ranging from the single digits above to teens below.  Highs on Thursday will be in the single digits below to single digits above zero.

*Here's the early call on the Tuesday Night/Wednesday snow event per Weather Prediction Center.  At least 4" of snow is possible in the blue and green outlined areas on the map.  Stay weather aware if you have travel plans in Southern parts of Minnesota, Wisconsin, and over parts of Iowa and Illinois around mid-week.
















Long Range Forecast - Confidence:  High.

(January 3-8)

Some snow is possible from the 3rd-5th as a low pressure system approaches from the west or northwest. At the moment this doesn't look like it'll be a major snow event for our area, but the potential is there for at least a minor snow event.  Below average temperatures continue during this period.
