Severe Thunderstorm Watch number 395 was in effect during this event.
A small but intense cluster of thunderstorms formed over far northeast Montana and tracked into far northwestern North Dakota early in the evening. An isolated supercell thunderstorm originating with this cluster persisted through much of the evening as it tracked southeast into south central North Dakota, bringing a destructive path of severe weather to many communities. Steep mid level lapse rates and favorable vertical wind shear promoted this thunderstorm's longevity.
A brief EF0 tornado occurred in far northeast McKenzie County during the most intense phase of this storm.  Hail to the size of golf balls and winds as high as 85 miles per hour also occurred during this severe weather episode.

Reported by: Social Media

This was a public report, through social media, of a tornado west of New Town, in McKenzie County. The person was uncertain of the exact location from a nearby town and so the location was estimated based on radar data. Through social media there was visual evidence of this tornado with debris visible on the ground, in open country. There were no reports of damage in real time nor in follow up contact with county officials. The tornado was therefore rated EF0. There was wind damage, likely associated with the rear flank downdraft of the parent severe thunderstorm, to the southwest of this tornado track in McKenzie County. See the entry for wind damage in McKenzie County.
