Ok, first things first: Minnesota has an official 'Summer Glory Index' to measure the awesomeness of summer weather in the state? Only in a land that experiences -40 degree temps, and -80 degree wind chills would this be a real thing. (But, this has been a nice summer.)
Storms will develop late this afternoon across western MN, spread eastward tonight, and exit to the south Wednesday. Large hail, damaging winds, and a few tornadoes are possible, particularly in the enhanced risk area.
Some redevelopment of storms is expected this afternoon as a cold front passes. Severe weather is possible with the afternoon activity, primarily from northern IA across southeast MN and central WI (areas #2 and #3 on the map).
A slight risk of severe thunderstorms is outlooked for much of the area today. Scattered thunderstorms are expected to develop mainly across the south and east. Storms that do develop could produce large hail damaging winds.
