Forecast Discussion for Northeast Minnesota and Northwest Wisconsin
Low pressure of 1002 mb has reached Lake Nipigon Ontario or northwest of Thunder Bay Ontario Canada as of 5 PM Today. A cold front attached to this low took a few hours longer to exit the Eastern part of Minnesota which led to a longer period of time spent in low clouds, fog, and a marine layer from Downtown Duluth and Superior and along the North Shore of Lake Superior in Northeast Minnesota. The front finally passed through Duluth-Superior between 2PM-3PM Today which caused the surface wind to shift to the west. This helped to scour out the marine layer of air and replaced it with a brief surge in temperatures. The cold front as of late This Afternoon had moved into Western and Northern Wisconsin with a few spotty showers noted along this front as it moved through the area Today. Partly sunny to mostly cloudy skies were found across Northeast Minnesota and Northwest Wisconsin Today with high temperatures in the 50s and 60s…but cold air advection and cold air STRATOCU clouds are quickly spreading southeast out of Northcentral Minnesota late Today behind the surface low and cold front. 5 PM H85 temperatures ranged from +1 to +7 degrees C across our local area. Winds Today which were out of the south or east turned into the west and southwest at 10-20 mph with gusts from 25 to around 45 mph found immediately behind the cold frontal passage.
(Today’s Upper Level Analysis)
Pattern change is well underway as the southwest flow aloft which has covered the Upper Midwest over the last several days is being replaced by a west and eventually northwest flow while an active storm track sets back up from the Southern-Central Plains toward the Ohio Valley into early next week. Main interest in our area Today was the strong H5 low and trough which continued to surge east through Southern Ontario/Upper Midwest/Upper Great Lakes region Today with 12 hour 500 mb height falls of 120 meters noted in Northern Minnesota-Southern Ontario per 5 PM RUC model analysis.
Look for partly-mostly cloudy skies with a possible light rain shower in Northern areas of the state. Lows will be in the 30s and 40s with winds from the west at 10-20 mph with gusts of 25-40 mph This Evening.
(Friday and Friday Night)
Partly to mostly cloudy skies will continue during this period with a new cold front moving into Northern Minnesota by Friday Night. This boundary could cause a few light rain or snow showers across Northern areas of the state Friday Night as we begin the month of May. High temps on Friday will be mainly in the 40s and 50s with lows Friday Night in the 20s and 30s. Winds during this period will be out of the west, southwest, or northwest at 10-25 mph.
Cold front will exit the area to the south on Saturday with high pressure then building into the Upper Midwest through early next week. Could see a rain shower or two over parts of the area on Saturday with some snow possible early in the day up North….Overall though it looks mainly dry from Saturday through Monday in our local area. High temperatures on Saturday will be in the 40s and 50s with 50s and 60s expected on Sunday. Lows Saturday Night and Sunday Night will be mainly in the 30s but some 20s can’t be ruled out in the traditional cold spots in Northern Minnesota especially Saturday Night. The next threat for some rain around our area could come the middle or end of next week as a complex weather system unfolds with some energy moving in from the west and possibly coming up from the south. Plenty of time to iron out those details.
