Localized Upper Midwest Severe Chances

12 Jun 2021, 5:30 am

There is a marginal risk (Level 1 out of 5) of severe storms Sunday afternoon and evening in Wisconsin, Minnesota, and Michigan. Strong winds greater than 60 mph and 1″+ hail are the primary threats with any severe storm development.


The energy for these storms is being generated by a weak surface low that looks to cross lake Superior Sunday morning. A strong upper-level low will create strong wind shear over the region with some moderate instability building in the warm afternoon temperatures.

The mid-to-late afternoon hours look the most promising for severe storms, though some storms could persist into the night across Lake Michigan.

Because storms are isolated, rainfall accumulation will be on the light side, but isolated flooding cannot be ruled out.

We are covering storm opportunities in your Central Regional Forecast, :30 after the hour on WeatherNation.
