Overnight storms could bring hail, 60 mph winds ... for next 6 nights

Be ready for some turbulent weather overnight. And get used to it.

The National Weather Service says thunderstorms moving into Minnesota Thursday night could bring large hail and damaging winds to central and southern counties.

They've also issued a hazardous weather outlook that shows several rounds of thunderstorms developing over the state from Friday through next Wednesday, mostly during the evening and overnight hours. Big storms, too. Possibly including hail an inch in diameter and winds of more than 60 mph.

The storms will not be continuous. In fact, we're likely to see some sunshine during the day. But as the Weather Service explains in its hydrologic outlook, that's part of the problem. A slow-moving upper air pattern with lots of humidity seems to be setting up shop above us. The sun interacting with that unsettled atmosphere will cause thunderstorms to regenerate, forecasters say, in a cyclical pattern that will last into next week.

What's more, if these storms hit the same areas repeatedly the risk of flash flooding will rise. That's already happening in the Brainerd Lakes area, which saw 3 to 5 inches of rain on Thursday. There was a flash flood watch for Cass and Crow Wing counties Thursday evening.

Fox 9 reports 2 to 4 inches of new rain is possible in the Twin Cities over the weekend as the pattern of partly sunny humid days and stormy nights takes hold.
