This system will also produce thunderstorms, and a few could pack gusty winds and hail across southern Minnesota south of the Twin Cities Friday.

The National Oceanic and Atmospheric Administration’s Storm Prediction Center paints a marginal risk for a few severe cells, basically south of a line from Mankato through Rochester. The Interstate 90 corridor has the highest chance of severe storms Friday.
