EF0 tornado in Griggs County, North Dakota

A brief touchdown was reported southwest of Walum, by spotters northeast of Wimbledon and north of Dazey. A persistent wall cloud structure with funnel-like appendage was viewed for several minutes as it passed along the Barnes and Griggs county line. Though a brief dust swirl was detected, no significant damage was apparent. Peak winds were estimated at 70 mph.

During the day of June 9th, temperatures over eastern North Dakota and the northwest quarter of Minnesota topped out in the upper 70s along the Canadian border to lower 90s along the North Dakota/South Dakota border. Mid level temperatures were very warm over the central Dakotas, helping to suppress convective development until early evening. By that point, thunderstorms broke out over southern Manitoba down through central North Dakota, mainly along a cold front. These storms tracked east-southeast, mainly covering the Devils Lake region, down through the central Red River Valley, and into the Mahnomen to Hubbard county corridor. A mix of tornadoes, hail, and strong winds were reported.
