More storms are expected to develop this evening and overnight and again late Wednesday. Flash flooding and severe weather are possible. 

It was an active evening Monday in northwest Minnesota. A potential tornado blew through Detroit Lakes and the National Weather Service office in Grand Forks, ND will do damage surveys Tuesday.

It’ll be steamy midday as clouds break up some with highs in the 80s to near 90 degrees along with dew points in the 60s to near 70 degrees. Northwest Minnesota will be cooler behind the cool front that’s the focus for the stormy weather. 

Our focus will then turn to storm redevelopment later this afternoon and evening into the overnight. Isolated storms will develop across central Minnesota with more storms developing in the Dakotas that will march east. There’s the potential for producing damaging wind gusts, large hail and heavy downpours into early Wednesday.

There’s a slight risk (level 2 of 5) for severe storms forecast for Tuesday into Tuesday night and early Wednesday. The main threat is from damaging wind gusts. 

In addition to the severe threat, storms moving over and developing over the same areas of central Minnesota could lead to flash flooding concerns. There’s a slight risk (level 2 of 5) for excessive rainfall in those areas.

At least a few inches with locally higher amounts of rainfall are possible in the regions that see continued storm development into early Wednesday. Forecast models vary on where this area sets up. Here’s one such scenario from NOAA’s High Resolution Rapid Refresh model: 

We’ll likely see some more scattered storms develop later Wednesday afternoon and evening due to lingering instability ahead of the advancing cool front.

Behind the front it will be slightly cooler and slightly less muggy for Thursday and Friday. Highs will be mainly in the low to mid-80s with dew points closer to 60 degrees. Enjoy that break because a heat dome is building for later in the weekend and early next week. We might see our hottest high temperatures yet this summer.
