Humidity nudges higher Tuesday

Most of Minnesota sees another day of 90 degree heat

Minnesota is facing yet another hot day in our current heat wave, with higher humidity across most of the state and a few storms likely.

Tuesday’s forecast

Under predominantly clear skies overnight, but with dew points that have risen since Monday, Minnesota is starting 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 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 showers, particularly in the Arrowhead.

A better chance for widespread rain comes Friday, along with a slight break in the heat. That extended forecast will be updated around 9 a.m.
