Forecast Discussion for Northeast Minnesota and Northwest Wisconsin
Deep low pressure which brought the very warm temperatures and gusty winds (40 mph in the Twin Ports) to our area on Sunday moved rapidly to the east and as of 3 PM this low was getting ready to move into New England. A quick shot of "cooler air" dropped south into Northern Minnesota/Northwest Wisconsin Today behind this low, but temperatures This Afternoon are still running above average for mid-February, but are about 10 to nearly 20 degrees cooler from Sunday. Highs Today were in the 30s with a quickly changing wind direction from north/northwest earlier in the day to the south This Afternoon. Wind speeds Today were under 15 mph.
Today's Upper Level Analysis:
500mb troughs covered Eastern Canada and the Northeast U.S. and also over the Pacific Northwest...In between the troughs was an upper level ridge which covered the Plains. 850mb temperatures took a tumble across our local area Today and ranged from -4 to -8 degrees C This Afternoon per RUC model analysis, but a large area of +4 to +12 degree C 850mb temps covered the Northern Plains and Northern Rockies, some of that will spread east into the Upper Midwest in coming days.
Partly to mostly cloudy skies will continue with lows generally in the 20s. South or southeast winds under 20 mph are expected Tonight. High pressure extending from north of Lake Superior to Eastern Nebraska late Today will settle south/east through the night.
Tuesday and Tuesday Night:
Southerly flow will kick in during this period with mild temperatures continuing. Highs Tomorrow will be in the 30s and lower 40s with lows Tomorrow Night in the 20s and lower 30s. Partly to mostly cloudy skies are forecast with the possibility for some patchy fog or light freezing drizzle early Tuesday Morning, and again late Tuesday Night.
Warm temperatures will continue Wednesday and Thursday before colder air moves in. High temperatures will be in the 30s and 40s Wednesday and Thursday with lows in the 20s and 30s. A cold front will be centered to our northwest/north at mid-week, this boundary will settle south and could move into Northern Minnesota on Thursday. Low pressure is expected to move into the Northcentral Rockies/Western High Plains on Thursday, the forecast models have this low moving rapidly toward the northeast Thursday Night before exiting to the east on Friday. The bulk of the precipitation associated with this storm is expected to be on the cold side of the system (west-northwest of the low pressure track) as a result it doesn't look like will see much precipitation in Northern Minnesota and Northwest Wisconsin late this week based on latest model projections. Anything that does fall Thursday and Thursday Night will be in the form of drizzle or freezing drizzle before cold air spreads in causing any light precipitation to change over to snow late Thursday Night or Friday. Early indications point toward a 1-2" snowfall late Thursday Night/Friday, along and north/northwest of a line from Bigfork to Grand Marais. Note: Nothing is set in stone just yet regarding this late week system, and the models could flucuate a bit in coming days, so things might change just a bit.
The overall 500mb pattern consisting of a Western U.S. trough is forecast to continue through the rest of February, this could signal the beginnings of a more active weather pattern for the Upper Midwest, but the exact track of lows/disturbances that lift out of this trough will determine whether or not we see any precipitation around our area.
