Minnesota's hot weather moderates slightly by the weekend
The Twin Cities remains under a heat advisory through Thursday
Minnesota’s heat wave continues, and as the humidity nudges higher the weather turns stickier and occasional showers and storms become more likely.
Monday’s forecast
Under predominantly clear skies overnight, but with dew points that have risen since Monday, Minnesota started Tuesday warm and somewhat muggy, with most of the state in the 60s and a few 70s, including around the Twin Cities.
Highs stay 10 to 20 degrees above average again Monday, with a few 80s north, but almost the entire state is in the 90s again.
Because of the warm start, elevated humidity and hot daytime weather, the Twin Cites and surrounding areas are still under a heat advisory that lasts all of Tuesday.

A stationary boundary has settled over Minnesota that will keep occasional showers and storms across the state the next couple of days. While isolated wet weather chances are statewide, the most likely area to see scattered activity is northern Minnesota.
Northern Minnesota already saw storms overnight Monday, and is starting Tuesday with a couple isolated showers.
The heat diminishes
The week ahead stays very hot for early June, with most of the state the in 90s through at least Thursday, followed by highs in the 80s.
Overnight lows remain warm also, with most places staying in the 60s, and southern Minnesota especially seeing 70s.
Because of the hot days, warm nights, and elevated humidity, the Twin Cities remains under a heat advisory through Thursday evening.
That area may be expanded, or the time frame extended as conditions warrant.
Meanwhile, the stationary boundary keeps a few scattered chances for showers or storms around, especially in northern Minnesota, until Thursday. None of that activity is expected to be widespread or likely to become severe.
The next statewide rain chance comes Friday with scattered showers and storms.
Much of the rain should stay light and under one-quarter inch, and the wet weather will be scattered along with dry breaks.
The associated clouds and moisture should temper the heat slightly. There is some uncertainty in the Friday temperatures, as to where in the 80s highs will fall.
More sunshine would make upper 80s probable, but if clouds move in earlier, mid or lower 80s become possible.
One model for the Twin Cities shows a more significant drop on Friday to 81 degrees.
While that projection may slightly overestimate how much the Twin Cities cools, it is looking likely that highs in the 80s will be more prevalent by the weekend, versus the current 90s.
