On the evening of June 16th, mid level temperatures were very warm over the eastern half of North Dakota and the northwest quarter of Minnesota, which helped prevent any thunderstorms from forming. However, just after midnight CDT of the 17th, a few weaker thunderstorms formed and tracked along the Canadian border in northeast North Dakota and northwest Minnesota. Then, around sunrise of the 17th, severe thunderstorms formed around the Maddock and New Rockford, ND, area, and began to track east-northeast. These storms quickly turned into a line of storms that showed bowing segments, or indications of strong winds, as well as hail. These storms reached the central and northern Red River Valley early in the morning, where the line expanded further southward into most of northwest Minnesota by mid to late morning.
