Forecast Discussion for Northeast Minnesota and Northwest Wisconsin
An extremely cold airmass remains over our area Today. Low temperatures last night plunged to the teens, 20s, and 30s below zero in our local area which is anywhere from 20 to 30+ degrees below average for late February. High temperatures Today only made it to the single digits to around 10 above zero which is 20+ degrees below average for this time of year. Mostly cloudy skies with areas of light snow (very small snowflakes) affected all of Northwest Wisconsin, and areas south of Highway 2 in Minnesota with accumulations generally around 1/2". Skies north of this area of light snow were mostly sunny Today. Winds Today were light and variable under 12 mph. Surface map as of 4 PM featured high pressure of 1014mb centered along the Eastern Minnesota-Western Wisconsin border.
Today's Upper Level Analysis:
Westerly flow aloft covered the Upper Midwest Today per water vapor satellite imagery with a strong upper level jet of 120-150 knots extending from the Southwest U.S. to the Central-Southern Great Lakes per RUC model analysis. A disturbance pushing through the Upper Midwest in this fast flow aloft helped to trigger the light snow Today. A powerful 500mb low continued to push S-SE through California Today with H5 temperatures of -34 degrees C and 850mb temperatures of as low as -4 degrees C in parts of California Today. 12 hour 500mb height falls of 90-120 meters were occurring Today in portions of the Southwest U.S. as this storm moves in.
Another night of frigid temperatures is ahead as lows drop to the single digits, teens, and 20s below zero in Northern Minnesota and Northwest Wisconsin. Partly to mostly cloudy skies are expected Tonight with variable winds under 12 mph.
Sunday and Sunday Night:
Partly to mostly cloudy skies are expected this period with flurries or a few snow showers possible at times, mainly in Northern Minnesota. Temperatures will warm-up compared to previous days with highs on Sunday in the 20s with lows Sunday Night in the single digits to lower teens above zero. Winds will be out of the south or southwest under 15 mph on Sunday with winds turning to the northwest or north under 20 mph Sunday Night. Strong low pressure is forecast to lift E/NE out of the Southcentral Plains from Sunday through Monday, this storm will have no impact on our local area, but it could produce a significant severe weather outbreak (possible tornadoes) from Eastern Kansas and Eastern Oklahoma, east through the Ohio Valley.
Temperatures will be closer to average for Monday and Tuesday with highs in the 20s and 30s with lows in the teens and lower 20s Monday Night with a shot of cold air moving back in Tuesday Night and Wednesday with lows Tuesday Night in the single digits below to above zero. Looks mainly dry for Monday and Tuesday, but low pressure passing by to our northwest/north on Tuesday will drag a cold front south into our area, this could result in a few flurries in Northern Minnesota Tuesday Afternoon/Evening. Next opportunity for a little bit of snow will come late next week (Thursday-Friday time frame) doesn't look like a very big deal at this time, perhaps an inch or two for some portions of our area.
