Several forecast models develop scattered thunderstorms in southern Minnesota overnight into Thursday morning. There are differences as usual in timing and coverage.

The forecast model loop above runs between 10 p.m. Wednesday and 10 a.m. Thursday.
Locally heavy rainfall possible

Highs Thursday likely push the 80-degree mark once again in southern Minnesota, with 70s all the way north to Canada.
