Severe Sunday: Damaging winds, large hail in multiple lines of storms expected in Minnesota

There's already been reports of golf ball-sized hail in Minnesota.
Publish date:

A potentially stormy 48 hours is in the pipeline for the Twin Cities and portions of Minnesota Sunday and Monday as a system slowly works it way through the Upper Midwest. 

Multiple storms in east-central Minnesota and western Wisconsin (near Rice Lake) reached severe levels early Sunday morning, including one cell that dropped hail the size of golf balls near Braham, Minnesota. 

According to the National Weather Service-Twin Cities, a "fairly organized band of thunderstorms" is expected to develop mid-to-late afternoon Sunday across central Minnesota and then trek eastward through the Twin Cities and into western Wisconsin.

These storms are expected to pack some punch with possible damaging winds and large hail, in addition to very heavy rainfall and frequent lightning. 

Here's a future radar simulation from noon Sunday until 4 a.m. Monday. This is a simulation of what could happen, not what will happen. 


As you can see in the radar simulation, a line of storms is expected to develop in the Dakotas and race through northern Minnesota later Sunday night into Monday morning as well.

Those storms will also be capable of producing damaging straight-line winds and large hail. 

Areas shaded in orange are under an enhanced risk for severe storms. Yellow means scattered severe storms are possible.

In addition to the storm threat will be a noticeable return of tropical humidity, with temps close to 90 and dewpoints rising into the mid-70s creating a very uncomfortable outside experience. 

On Monday, high temps will again soar into the mid-to-upper 80s in the Twin Cities and southeastern Minnesota, but back behind the front is cooler air with temps struggling to break 70 in northwest Minnesota. 

Once again, the Twin Cities and southeastern Minnesota could be under the gun for severe storms.
