Forecast Discussion for Northeast Minnesota and Northwest Wisconsin
Low pressure of 1006mb has moved into the Eastern Great Lakes late This Afternoon with an inverted trough extending west-northwest into Northern Wisconsin and Northeast Minnesota. Snow showers and flurries were widespread Today from Northeast Minnesota to the South Shore of Lake Superior with overcast skies affecting most areas Today, although there's been some breaks in the clouds especially west of the Iron Range. Temperatures This Afternoon were on the chilly side with teens and 20s across our area. Note: Even colder air was found in Western parts of Minnesota Today with temperatures only in the single digits! Winds Today were out of the northwest at 5-15 mph with higher gusts through midday.
Today's Upper Level Analysis:
Vigorous storm system which passed through Minnesota Friday Night continues on it's eastward journey through Ontario Province and the Great Lakes This Afternoon per water vapor satellite imagery. In wake of this storm, the 500mb flow has shifted to the northwest with a fresh batch of late season cold air covering the Northern Plains and Upper Midwest Today with 850mb temperatures of -4 to -8 degrees C per RUC model analysis.
An inverted trough will remain nearly stationary from the Arrowhead of Minnesota toward far Northern Wisconsin, snow showers and flurries occurring near this front should start to decrease This Evening with some flurries possible Overnight. Lake effect snow showers could affect the South Shore of Lake Superior before Midnight with 1-2" accumulations possible. Little if any additional accumulation is expected elsewhere. Partly to mostly cloudy skies with lows in the single digits, teens, to around 20 degrees are forecast in our area Tonight with a few subzero low temperatures possible in far western areas from International Falls to Brainerd and off to the west. Winds Tonight will be out of the northwest or west under 20 mph.
Sunday and Sunday Night:
High pressure will pass through the Upper Midwest during this period. Most areas will be dry with partly to mostly cloudy skies. A few flurries could continue near Lake Superior, but no accumulations are expected. Highs Tomorrow will be in the 20s and 30s with lows Tomorrow Night mainly in the teens. Variable winds will become more southerly by Sunday Night, wind speeds will be under 20 mph through this period.
Southerly winds and milder temperatures will occur on Monday as we sit between low pressure well to our northwest and high pressure to our east. Highs on Monday will be in the 30s and lower 40s. Looks dry Monday and for most of Monday Night with low temperatures Monday Night in the 20s to around 30 degrees. Low pressure will pass through Central Canada on Tuesday with a cold front attached to this low pushing through our area on Tuesday. Might be some showers of rain, sleet, or wet snow as this front moves through on Tuesday, but precipitation amounts look to be on the light side. High temperatures on Tuesday will be in the 30s and 40s with lows Tuesday Night mainly in the 20s with dry conditions moving back in. The next system to keep an eye on will move into the Upper Midwest sometime during the Wednesday Night-Thursday Night time frame, another round of precipitation which looks to be mostly rain may affect parts of our local area sometime on Thursday the way it looks now.
Larger storm systems are still showing up on the long range GFS and EURO models for next weekend and beyond, the last two weeks of March could be rather active at times from the Northern Plains and Upper Midwest, south through the Central Plains if current model solutions are anywhere close to being right.
