What happened
The episode as NWS FGF wrote it up.
August 15th was the fourth day of 90 plus degree temperatures across eastern North Dakota. A cold front over western North Dakota advanced into eastern North Dakota during the evening. Thunderstorms formed out ahead of the front in the Valley City, North Dakota area, and tracked east-southeast along Interstate 94 into the Fargo-Moorhead area before they briefly weakened. As the echoes worked into portions of Clay County, they intensified again. These storms continued tracking east-southeast through eastern Otter Tail County, producing strong wind gusts and large hail.
