The pleasant weather pattern Minnesota has been in for the past couple weeks is about to end, and the first signs of a more active weekend will be felt as temperatures rise into the upper 70s and low 80s Thursday, coupled with increasing humidity. 

Thursday will be pretty much perfect otherwise, followed by a warmer and more humid Friday that could culminate with strong to severe storms moving from the eastern Dakotas into western parts of Minnesota late Friday into the overnight hours, according to the Twin Cities office of the National Weather Service. 

The weather service notes that the severe threat for western Minnesota will be iffy, but if storms maintain strength out of the Dakotas they will certainly have enough proper atmospheric conditions to pose a severe wind, hail and isolated tornado threat.

Saturday looks to dry out for most, the weather service says, followed by a slight chance of storms re-firing Saturday evening, though the Twin Cities forecasters at the NWS office are currently favoring a dry Saturday night. 

Sunday could be the most dynamic storm day of the weekend, as the Storm Prediction Center has already placed a sizable area of Minnesota in a 15% risk for severe weather, including strong lines of storms capable of producing damaging winds.

The forecast discussion from the NWS Twin Cities says Sunday evening could be "quite active," with high rain totals also possible. 

Meteorologist Tom Novak of Novak Weather discussed the significant pattern change in his Wednesday briefing for Bring Me The News. 

"Especially later on the evening Sunday for the potential for severe weather and heavy rains," explains Novak Weather. "There's no reason not to expect some significant rains – and that could be rain in excess of 2 inches in some places. There's no doubt that our environment will become much more favorable for thunderstorms and heavy rains."
