| Episode Narrative | Thunderstorms developed over parts of western North Dakota as a cold front pushed into the area. Enhanced instability and deep layer shear led to the development of severe weather. One storm produced an EF0 tornado in Williams County, southeast of Ray. The tornado produced no damage to structures. Otherwise, the main severe threat was hail, with two inch diameter hail being the largest reported, falling in Burke County. |
| Event Narrative | This tornado was reported by a trained spotter to be in open country southeast of Ray. There were no reports of damage or impacted structures so the rating is EF0. |
