Isolated severe storms possible around Twin Cities; hot and humid conditions return

Unsettled weather with hot and humid conditions is returning Friday.
Author:

Morning rain will give way to hot and humid conditions and a threat of strong thunderstorms in eastern Minnesota on Friday. 

According to the National Weather Service, heat indices (what it feels like outside) will range from 90-95 degrees in the Twin Cities, with a threat for isolated severe storms mainly between 6 p.m. and midnight. 

The simulated future radar from the NAM 3KM model run Friday morning isn't all that impressive, but any storms that do develop will pose the risk of dropping large hail and producing damaging winds.

The better severe threat is confined to far northeast Minnesota up into Canada. That's where the Storm Prediction Center says "an arc of thunderstorms is expected from western Ontario across the Arrowhead, with hail and strong wind gusts possible."

A brief tornado can't be ruled out in northeast Minnesota.

Further south towards the Twin Cities and down through south-central Minnesota, storms will be isolated. Not everyone will get rain. More details from the NWS in the Twin Cities. 

"The current thinking continues to be isolated development this afternoon, with storms becoming most numerous this evening south of a St. Cloud to Willmar line. A couple of these storms may become supercells given the strong deep layer shear, capable of mostly large hail."

For the weekend, things look really good Saturday across the state with highs in the middle 80s – maybe a few low 90s in western Minnesota – followed by what is looking to be a washout pretty much everywhere on Sunday. 

We'll tighten the details on the Sunday rain/storms in an update to the Weather MN blog on Saturday.
