Several waves of rain and thunder will cross Minnesota through this weekend and early next week. It may culminate in a potentially bigger, more organized storm system next Monday.

Rainfall totals are usually more localized during summerlike thunderstorms. But many forecast models suggest overall precipitation totals could reach 1 to 3 inches locally by next Tuesday evening.
