Today’s Weather Summary for Northeast Minnesota and Northwest Wisconsin

A cold front sagged south/east through Northern Minnesota Today.  As of late This Afternoon the cold front has moved into Northwestern Wisconsin.  Light snow did develop during the Afternoon hours across portions of Northern-Eastern Minnesota with accumulations generally of a half inch or less.  High temperatures Today were in the lower to middle 30s which is slightly above average as we close out the month of November.  Winds Today were out of the southwest or north under 15 mph.

Today’s Upper Level Analysis:

Westerly flow aloft was in place over the Upper Midwest per RUC model analysis.  500mb trough was digging S/SE through the Rockies with an area of 120-180 meter 12 hour 500mb height falls extending from Eastern California to Southern Wyoming per RUC model analysis.  A rather tight temperature gradient was found across the Upper Midwest This Afternoon with 850mb temperatures ranging from -6 degrees C in Northwest Minnesota to zero degrees C in Central Minnesota to +4 degrees C in Southern Minnesota, this tight temperature gradient is helping to generate our snowfall Tonight.

Forecast Discussion for Northeast Minnesota and Northwest Wisconsin

Tonight:

A cold front will exit Northwest Wisconsin This Evening.  Areas of light snow and flurries will continue most of the night.  Note:  Patchy light freezing drizzle is also possible mainly early This Evening.  A considerable amount of cloudcover will be found in our area with lows in the teens and 20s with some single digits possible in Northern Minnesota.  Winds will be out of the north or northwest at up to 15 mph.

Thursday and Thursday Night:

Scattered lake effect snow showers/flurries are possible on Thursday along the South Shore of Lake Superior, snow accumulations of around an inch are possible for Northern Douglas, Bayfield, Ashland and Iron Counties in Northwest Wisconsin.  Dry weather will return to these areas by Thursday Night while the remainder of our area will be mainly dry after some Morning flurries.  Highs on Thursday will be in the teens and 20s with lows Thursday Night in the single digits and teens with some locations in Northern Minnesota possibly dropping a few degrees below zero.  Winds will be out of the north or northwest at 10 to 20 mph on Thursday and from the west or southwest under 15 mph Thursday Night.

Note:  Total snowfall accumulations by Thursday will range from 1-2″ in Northwest Wisconsin and Northeast-Eastcentral Minnesota with locally heavier amounts of 3-4″ possible along the South Shore of Lake Superior.

Extended Forecast:

A cold front will move E-SE across the Upper Midwest on Saturday with one low passing by to our northwest and another one heading northeast from the Southern Plains.  Some snow showers and flurries are possible in Northern Minnesota and Northwest Wisconsin from Saturday into early Sunday, but accumulations if any look very light.  Highs on Saturday will be in the 20s and 30s with lows Saturday Night in the teens and 20s.  Highs for Sunday will be in the 20s with lows Sunday Night in the teens.  A clipper type low is forecasted to move into the Northern Plains and Upper Midwest late this weekend into early next week, this system could bring another minor snow event to our area sometime between Sunday Night-Monday the way it looks now.

Two brief shots of arctic air are possible for early next week behind that clipper system with another surge of arctic air possible for late next week, around December 9th.

Today’s Weather Summary for Northeast Minnesota and Northwest Wisconsin

High pressure ridge of 1026mb stretched from the Western High Plains to the Upper Midwest.  Sunshine was in abundance across our area Today with high temperatures mainly in the lower to middle 30s.  Winds were out of the southwest or north-northwest under 15 mph.

Today’s Upper Level Analysis:

Potent storm system was moving north into the Ohio Valley per water vapor satellite imagery.  Widespread very strong 12 hour 500mb height falls of 120-240 meters covered the Ohio Valley, Southern Great Lakes and parts of the Mid-Atlantic per RUC model analysis.  Northwest flow aloft was in place over the Upper Midwest Today with a seasonably chilly airmass in the Upper Midwest with early Evening 850mb temperatures of -2 to -4 degrees C while an area of warmer air +2 to +6 degree C 850mb temperatures covered the Dakotas late Today per RUC model analysis.

Tonight:

High pressure from the Plains to Upper Midwest will keep us quiet under mostly clear skies.  Lows will be in the teens and 20s, but single digits are likely in Northern Minnesota.  Winds will be variable or southwesterly around 10 mph.

Wednesday and Wednesday Night:

A cold front will move southeast across our area from Wednesday into Wednesday Evening while a wave of low pressure moves up along this boundary.  Partly sunny to mostly cloudy skies are expected on Wednesday with highs in the 20s and 30s.  Mostly cloudy skies are forecasted Wednesday Night with lows in the teens and 20s.

Light snow and flurries should develop Wednesday Afternoon/Evening across our area with some snow lingering through the Overnight hours, especially from Eastern Minnesota into Northwest Wisconsin.

Today’s Weather Summary for Northeast Minnesota and Northwest Wisconsin

A cold front was moving into Central Minnesota late This Afternoon.  Clouds earlier in the day gave way to occasional sunshine during the Afternoon.  High temperatures were in the 30s to lower 40s with winds out of the west or southwest at 5 to 15 mph with some higher gusts.

Today’s Upper Level Analysis:

Powerful upper level low with 150 meter 12 hour 500mb height falls per RUC model analysis covered Mississippi and Alabama early This Evening with a pocket of -2 to -6 degree C 850mb temperatures in place underneath this H5 low across parts of the Southeast U.S.  Note:  Record to near record warmth occurred in the Mid-Atlantic Today with highs in the 60s, versus the 30s and 40s over parts of the Southeast U.S.  W-NW upper level flow was in place across the Upper Midwest with a 500mb trough along with it’s 60-150 meter 12 hour 500mb height falls heading E-SE across Central Canada, Northern Plains and Upper Midwest per water vapor satellite imagery and RUC model analysis.  850mb temperatures as of 4pm ranged from -8 degrees C in Central Manitoba Province to -2 degrees C in Northern Minnesota to +6 degrees C in Southern Minnesota per RUC model analysis.

Forecast Discussion for Northeast Minnesota and Northwest Wisconsin

Tonight:

A cold front will move off to our south/east This Evening.  Clear to partly cloudy skies are on tap with lows in the teens and 20s with a few single digits possible in far Northern Minnesota.  Might be a few lake effect flurries or snow showers after Midnight along the South Shore of Lake Superior in Northwest Wisconsin, but little if any accumulation is expected.  Winds Tonight will shift to the north/northwest at 10 to 20 mph.

Tuesday and Tuesday Night:

A ridge of high pressure will cover the Plains and Upper Midwest while strong low pressure heads N-NE into the Ohio Valley.  Clear to partly cloudy skies will occur in our area with highs on Tuesday in the 20s and 30s with lows Tuesday Night in the teens with some single digits possible in Northern Minnesota.  Winds will be variable to north/northwest at 5 to 15 mph during this period.

Extended Forecast:

Wednesday will be dry with high temperatures mainly in the 30s.  Another cold front pushes south/east across our area Wednesday Night-Thursday, still looks like there could be a band of light accumulating snow as this front moves through, although what area/s see this minor snow event is uncertain at this time.  Consensus per Today’s model data would be for Northern Minnesota to have the best chance for a 1-2″ snowfall from Wednesday Night into Thursday, but this could change.  Low temperatures Wednesday Night will be in the teens and 20s with highs on Thursday mainly in the 20s.  Lows Thursday Night will be in the single digits and teens.

High pressure moves off to our east while a warm front moves into the Upper Midwest.  Partly to mostly cloudy skies will be found in our area with lows in the teens and 20s, but some single digits are possible in far Northern Minnesota especially if skies become mostly clear.  Patchy fog could also develop late Tonight mainly north of the Iron Range.  Winds will become southwest at 5 to 15 mph.
