Forecast Discussion for Northeast Minnesota and Northwest Wisconsin
Low pressure of 994mb has moved into Northeast Ontario Province late This Afternoon. Clouds and isolated showers were occurring in our area Today on the backside of this low. High temperatures Today were in the 60s to lower 70s with north or northwest winds at 5-15 mph. Note: Last week's heat wave in portions of Central Canada has been replaced with late winter like temperatures Today with 30s and 40s being reported in parts of Ontario and Manitoba Province.
Today's Upper Level Analysis:
Northwest 500mb flow has spread into the Upper Midwest Today in wake of this past weekend's storm which was moving east across the Great Lakes and Eastern Canada per water vapor satellite imagery. The next system which looks very impressive on the water vapor satellite This Afternoon was moving east across California. Note: This system could lead to a major outbreak of severe thunderstorms and tornadoes for the Central Plains, Ohio Valley, and Mid-Mississippi areas from Tuesday through Thursday.
Pop up showers will come to an end This Evening, skies through the night will remain partly to mostly cloudy with lows mainly in the 40s. Winds will be out of the north, northwest, or east under 20 mph.
Tuesday and Tuesday Night:
High pressure will build in from the north. Partly cloudy skies are forecast during this period with highs Tomorrow in the 50s and 60s, cooler near Lake Superior. Lows Tomorrow Night will be in the 30s and 40s. Winds will be out of the north or east under 20 mph.
Dry weather should continue for our area from Wednesday through Friday, May 25th-27th. High temperatures for Wednesday and Thursday will be in the 50s and 60s, but it will stay cooler near Lake Superior. Lows Wednesday Night and Thursday Night will be in the 30s and 40s. Note: Patchy frost could develop in Northern Minnesota and Northwest Wisconsin Tuesday Night, Wednesday Night, and Thursday Night.
Quite a bit of uncertainty showing up in the computer models for the Memorial Day weekend, and these differences carry over into the middle of next week. There are some indications that a SW 500mb flow may develop with an upper level trough in the Western U.S. Very warm and humid air would start to spread north if this type of pattern develops. Low pressure over the Rockies, Western High Plains region with a warm front extending E-NE of that low could also lead to some wet/stormy weather at times for this weekend into the early/middle part of next week.
