Heat, humidity return to Minnesota this week

Wednesday will be the hottest, with heat index values rising into triple digits.

Sunday's heat across southern Minnesota and storms in northern parts of the state were a good precursor of what's to come the rest of the week. 

Storm chances will be limited the next 48 hours, but they'll return Wednesday. Meanwhile, Monday and Tuesday will be quite typical in terms of summer heat, but Wednesday will bring another opportunity to walk outside and feel like you're in a sauna. 

Temps across southern Minnesota, including the Twin Cities, will be in the upper 80s to low 90s each of the next three days. But dew points rising into the 70s will likely push heat index values on Wednesday in the 100- to- 105-degree range in west-central Minnesota, and maybe a tad lower in eastern parts of the state, according the National Weather Service

MPR meteorologist Paul Huttner noted in his blog that the next 4-6 weeks are generally the hottest of the summer, with average highs in the Twin Cities reaching 84 degrees. 

Wednesday will also bring the chance for severe storms, as the Storm Prediction Center already has the northern half of Minnesota under a slight risk for severe weather. Not only will storms be capable of producing large hail and damaging winds, but a very moist airmass will allow for torrential rainfall. 

With that, a large area of northern and central Minnesota are being monitored closely for excessive rainfall risks. 

The areas in yellow are in a slight risk for excessive rainfall on Wednesday.

Minnesota has been victim of extreme rainfall for the last month, with Gov. Mark Dayton declaring a State of Emergency in 36 counties ravaged by flooding and damage from intense summer storms.
