Northwest flow aloft to start with, transitioning to more of a west/southwest flow aloft this weekend into early September.

A dark and gloomy day in most of the Northland thanks to a combination of thick wildfire smoke and overcast skies, there was a bit more sunshine, however, over northwest portions of the area, roughly from International Falls toward the Brainerd Lakes. A few downpours and isolated thunderstorms have been developing and collapsing through the day over parts of northeast Minnesota and northwest Wisconsin, if you got underneath one of these showers, it poured, but the majority of the area has stayed dry today. Highs today were in the mid 60s to mid 70s, near normal to about 10 degrees below normal for late August.
Mostly cloudy to partly cloudy skies will continue over the Northland with isolated showers in eastern Minnesota and northwest Wisconsin where brief downpours and isolated thunderstorms are possible into mid evening. Patchy fog could develop overnight. Lows will range from the upper 40s to around 60 degrees.
Low pressure which was over far northern Missouri this evening is forecast to move to just east of Lake Huron by late Tuesday afternoon, then into eastern Canada by Wednesday, meanwhile high pressure builds S/SE out of the northern Rockies through midweek.
Partly to mostly cloudy skies are expected, still can’t rule out a stray shower mainly in northwest Wisconsin. Highs ranging from the upper 60s to middle 70s with N-NE winds.
Wednesday and Thursday:
Looks very pleasant with highs in the mid 70s to lower 80s. Dry with some sun both days.
