Overview
An area of low pressure lifting north-northeast across Northeastern South Dakota led to showers and thunderstorms across the region. As thunderstorms formed along a warm front stretching east into Minnesota, several tornadoes occurred across Day, Grant, and Roberts counties in South Dakota and Big Stone and Traverse counties in Minnesota.
