Parts of northwestern Minnesota saw strong to severe thunderstorms late Sunday afternoon. Those storms will spread eastward Sunday evening. Additional scattered strong to severe thunderstorms could develop elsewhere in Minnesota and western Wisconsin Sunday evening, but the main event in most areas will be later Sunday night and Monday morning.

Computer models show an organized batch of thunderstorms moving into western Minnesota after midnight Sunday night, then gradually spreading across the remainder of Minnesota and parts of western Wisconsin during the late overnight hours and Monday morning. Some of those thunderstorms could be severe.
