Storm chances arrive again in Minnesota Tuesday night into Wednesday morning, and then again Friday – and that's when there could be some hefty stuff moving through.
We begin the day with clouds associated with showers and storms in west-central Minnesota, but all of that activity will move northward. As it does, clouds will decay and the sun will break through with temperatures rising into the mid to upper 80s Tuesday afternoon.
The heat will be similar to Monday, but the humidity will up a tick or two so you'll really feel the moisture in the air. And naturally, that'll set the stage for widespread showers and storms overnight, with isolated hail and strong winds possible in the marginal risk area highlighted by the Storm Prediction Center in the map below (darker green).
Here's the simulated future radar from the NAM 3KM model (GIF might not load in all browsers), which shows storms firing around 10 p.m. in western Minnesota and moving east overnight. No major haymakers from Mother Nature with this round, but isolated severe storms are possible.
More storms could fire in far southern Minnesota late Wednesday into early Thursday, but nothing of major concern. Thursday, meanwhile, looks like driest day of the week for Minnesota.
The next storm system arrives Friday, and the Storm Prediction Center has already highlighted an area of the Dakotas and Minnesota for severe storm potential. The National Weather Service in the Twin Cities notes that it's too early to predict when and where storms will fire, but the severe setup should allow for large hail and damaging winds.
Again, timing will change, but as of now it appears that Friday's storms would come late in the day/night.
Once Friday's storm system moves through, the heat and humidity should retreat as more normal temperatures for this time of year are expected.
