A line of powerful thunderstorms rolled through the Dakotas and Great Lakes region Wednesday, flooding roadways and damaging several homes and businesses.

Wednesday's storms follow a three-day string of severe weather across the Northern Plans and Great Lakes. Additional thunderstorms are expected to develop in the Midwest and Central Plains on Thursday.
