Forecast Discussion for Northeast Minnesota and Northwest Wisconsin
Ridge of high pressure averaging 1022-1026mb covered the Plains and Western Ontario Province Today. A mainly quiet day with near seasonal temperatures as the month of September comes to a close. Highs Today were in the middle to upper 40s in the Arrowhead with 50s to around 60 degrees for the rest of us. A few lake effect showers did occur at times Today along the South Shore of Lake Superior, mainly affecting Ashland and Iron Counties. Winds Today were out of the north or east at under 15 mph.
Today’s Upper Level Analysis:
Northwest 500mb flow was in place across the Upper Midwest per water vapor satellite imagery. A potent upper level trough over the Eastern Great Lakes continued to dig south-east Today. Note: Upper level winds on the backside of this H5 trough were as strong as 130 knots late This Afternoon in far Southeast Wisconsin per RUC model analysis. Warmth was building backinto the Northern Rockies as an upper level ridge covered the Rockies and Western High Plains Today with widespread 80 degree temperatures from Alberta and Saskatchwan Province, south through Montana, Wyoming and the Western Dakotas.
Tonight through Saturday Night:
High pressure will move off to our south/east during this period. Expect clear-partly cloudy skies in our area with spotty lake effect rain showers over Ashland and Iron Counties Wisconsin coming to an end early This Evening. Low temperatures for Tonight will be in the 20s and 30s with highs Tomorrow in the 50s and 60s. Lows Tomorrow Night will be in the 30s and 40s. Winds will be variable Tonight at under 15 mph with southerly winds developing at under 20 mph for Saturday and Saturday Night.
The period from Sunday through at least Thursday of next week looks unseasonably warm at the moment as southerly winds lock in across the Plains and Upper Midwest. A cold front to our north for Sunday and Monday may try to sneak south and through parts of our area for next Tuesday-Wednesday, but the trend Today seems to be for this boundary to remain farther north than what the models have been showing during the past few days. An upper level trough will dig into the Western U.S. for next week with a fairly vigorous storm lifting north into the Dakotas toward the end of next week or next weekend…This system could bring some rain to Northern Minnesota and Northwest Wisconsin sometime between Friday-Sunday, October 7th-9th. High temperatures for Sunday and Monday will be in the 60s and 70s with an 80 degree temperature not out of the question, especially on Monday. Lows Sunday Night and Monday Night will mainly be in the 40s.
