Hudson Bay High keeps it windy, cool, and dry near Lake Superior through midweek; warmer temps inland

Howling winds will continue near Lake Superior the next few days with a stiff northeast wind 15 to 30 mph (gusting to around 40 mph) the wind will kick up some dust at times. Temperatures near Lake Superior won’t vary much through Wednesday with daytime highs of 45 to 55 degrees, and overnight lows around 40 degrees. Note: A cool lake breeze looks to continue past Wednesday, but not quite as windy as it will be the next few days, but still not real pleasant.

If you’re inland by 10 to 20 miles of Lake Superior your weather will be much nicer this week. High temps in the 60s and 70s Monday, Tuesday and Wednesday with a lot less wind.

Rain in far eastern Minnesota and southern portions of northwest Wisconsin is expected to end from NW-SE later this evening, and then it looks mainly dry across the Northland through Thursday.

Impressive rainfall totals over the past 12 hours south of the Twin Ports!

Abundant moisture continues to lift north out of the Gulf of Mexico today while lift associated with the strong low over Iowa results in a widespread area of rain (some heavy) from the Southern Plains to the upper Midwest today, but dry air pushing SW off the strong Hudson Bay high is keeping northern Minnesota and areas near Lake Superior dry today.

This will be a slow moving system, but it is forecast to remain offshore as it moves north-northeast, and eventually to the east-southeast later this week.

Temperatures are forecast to be above normal in northeast Minnesota and northwest Wisconsin this week, but near Lake Superior it will be quite a bit cooler!

Note: Normal highs in the Northland this week are generally in the middle 60s while normal lows are in in the lower 40s.
