A warm front lifted through the area in the afternoon with low level moisture rapidly increasing in its wake. This resulted in very strong instability developing over much of western into south central North Dakota. An early storm developed around mid-day as the front lifted over south central North Dakota, though the main area of thunderstorms developed later in the day over southeast Montana into northwest South Dakota as a short wave approached. These thunderstorms then moved into western North Dakota producing marginally severe hail and wind gusts.
