Isolated severe storms possible in southern Minnesota Saturday

There's a growing concern about flash flooding in southeast MN again.

After a very wet week across southern Minnesota, the weekend will bring much nicer and warmer weather. Well, for most people that'll be the case. But there are people in southern Minnesota who will get hit with isolated storms Saturday afternoon and evening. 

Storms will definitely be isolated in nature, so you'll have to get unlucky to get hit on what will otherwise be a warmer day with humidity on the rise. But any storms that develop will have enough instability to produce hail and strong winds.

In the Twin Cities, there's just a 20 percent chance of storms after 3 p.m., with an otherwise mostly sunny day with highs in the middle 70s. There's a better chance the storms remain south of the metro, and that's unwelcome news for areas that have been pounded by heavy rain this week.

"With ground nearly saturated from recent heavy rainfall, additional flooding will be possible in some areas, particularly south of Interstate 90," says the National Weather Service in La Crosse. "Be prepared for potential rapid rises and flooding on area streams and rivers, as well as mud and rock slides in steep terrain."

Storms that develop could redevelop over the same areas, thus raising the concern for higher rain totals that could exacerbate flooding concerns. With that, the NWS in La Crosse has issued a flash flood watch for Dodge,Fillmore, Houston, Mower, and Olmsted counties. 

Overall, today sets the stage for what'll be a summer-like stretch of weather in and around the Twin Cities. 

  • Sunday: Sunny and 80
  • Monday: Sunny and 83
  • Tuesday: Sunny and 84 with storms possible late

Enjoy the warmth and humidity because it could very well be the last 80-degree days of 2019.
