UPDATE 9:30 A.M.

A severe thunderstorm warning has been issued for Hennepin County, with large hail the main risk as the system makes its way into the metro area.

Original story

Storms that developed overnight in northern Minnesota are moving southeast, posing a risk for severe weather in central Minnesota Tuesday morning.

At 7 a.m., severe storms were marching through Cass, Crow Wing and Aitkin counties in central Minnesota, impacting areas like Brainerd, Nisswa, Staples and Crosslake. The storms were moving southeast at 30 mph and capable of producing 60 mph winds and quarter-sized hail, in addition to very frequent lightning and torrential rain. 

"Severe weather is possible today, with the best chance of storms expected north of I-94," says the National Weather Service Twin Cities. "Early morning thunderstorms may impact central MN, with the storm threat continuing into the afternoon for the remainder of the area. Remain weather aware."

It's difficult to predict if the storms will hold together and reach the Twin Cities area, but the HRRR computer model suggests that they will weaken by the time they reach the metro between 10-11 a.m.

But then again, the Storm Prediction Center notes that once storms become organized, as this line is, they can survive longer than expected. That's what folks in east-central Minnesota need to be alert to. 

"HiRes models are adamant that thunderstorms will weaken as they approach western Wisconsin around mid-day, but that seem strange given how unstable the atmosphere will be," the NWS Twin Cities notes.

Once the storms move through during the morning hours, partly sunny skies are in the forecast with a high around 80 degrees. 

Expect a much less humid, pretty much perfect Wednesday and Thursday with sunny skies and highs in the 70. Friday will be really nice but humidity will start to build back in, setting the stage for a potentially stormy weekend, with the NWS Twin Cities suggesting the best chance for storms will be Saturday night into Sunday morning.
