A line of severe thunderstorms moved into northwest South Dakota during the overnight hours. The line developed into a bow echo as it passed across the area, producing a widespread area of 60 to 80 mph winds along with some hail. The combination of strong winds and hail resulted in broken windows across parts of the area. The hail and wind also resulted in the death of wildlife and some crop damage.
