Severe storm potential ramps up Friday in southern Minnesota

Some parts of MN have a chance for strong storms the next three days.
Publish date:

No major changes to the forecast from the National Weather Service as parts of southern Minnesota could be on the receiving end of severe storms the next three days. 

Today (Thursday), any severe storms are expected to remain along and south of Interstate 90 in far southern Minnesota, with a higher risk of storms reaching severe limits in Iowa. Isolated damaging wind and large hail are the main hazards Thursday.

The severe potential ramps up Friday in southern Minnesota, with the greatest risk for southwest and south-central areas, including Marshall, Worthington and Mankato. However, storms could become severe anywhere along and south of Interstate 94, including in the Twin Cities. 

Tornadoes are not likely, but large hail will be possible, according to the NWS. 


The same areas under a severe risk Friday will again have severe storm chances on Saturday, although the general threat will be lower. Hail will again be the main threat with any storms that mature. 

That said, Saturday will be a complete weather wild card because a warm front is expected to be stationed somewhere in the region, with temps on the north side of the front sticking in the 40s and 50s, with temps in the 60s to possibly the 80s south of it. 

Here's the simulated future radar (NAM 3KM model, may not work in all browsers) showing what could happen between 12 a.m. Friday through 10 a.m. Saturday. You can see some storms possibly reaching far southern Minnesota overnight into Friday morning, and then more robust storm development late in the day Friday. 


Regardless of what happens, widespread rain is expected through the weekend and flooding concerns are legitimate. Four or more inches of rain could fall pretty much anywhere in the southern half of the state, the NWS warns.
