Forecast Discussion for Northeast Minnesota and Northwest Wisconsin
Mostly cloudy skies continued to cover portions of Northwest Wisconsin Today while sunny skies continued in Northern Minnesota. Highs Today were mainly in the 30s with a few locales in Minnesota climbing to 40 degrees. Winds Today were out of the north or east under 15 mph. Surface map This Afternoon featured high pressure of 1022-1030 mb strectching from the Northern Plains to Ontario Province. Low pressure of 1000 mb was centered in Western New Mexico.
Today’s 500 mb analysis:
Upper level lows covered the Southwest U.S. and Northeast U.S. with a north/northwest 500 mb flow covering the Upper Midwest.
Tonight through Monday Night:
Partly to mostly cloudy skies will be found across our area during this period. A few flurries could fall in the Arrowhead of Minnesota and in parts of Northern Wisconsin Tonight, otherwise mainly dry conditions should prevail. Lows Tonight and Tomorrow Night will be in the single digits and teens but some of the traditional cold spots could drop into the single digits below zero both nights. Highs Tomorrow will be mainly in the 30s. North, northeast, or west winds will continue under 15 mph with high pressure continuing to sit across the Northern Plains.
Mainly dry conditions will continue from Tuesday through the end of the week with a blocking pattern remaining in place across the Upper Midwest. High temperatures for Tuesday and Wednesday will be mainly in the 30s with lows Tuesday Night and Wednesday Night in the single digits and teens.
Looking out toward late next weekend and into early the following week, or from March 7th-10th is a period to keep an eye on as there could be a rather strong low pressure system lifting northeast out of the Plains. GFS model Today is the most progressive with this system while the EUROPEAN model has trended much more amplified and much slower in lifting the system out of the Plains. Still plenty of time to monitor this potential storm system that may impact Minnesota sometime between the 7th-10th of March. Should this storm move our way, then we could see some wind, snow, and rain around the Upper Midwest at somepoint during that aforementioned time period.
