Late in the afternoon of September 19th, scattered thunderstorms developed across southern Manitoba. These storms seemed to develop around a weak surface low that had lingered over the northern Red River Valley through the afternoon. One thunderstorm crossed into Pembina County in northeast North Dakota, and immediately showed tornadic tendencies. As this storm crossed into Kittson County in northwest Minnesota it produced a tornado. Other storms resulted in a second tornado as well as several reports of large hail.
