What the National Weather Service wrote

Brief spin up was reported in an open field which mitigated any damage. Therefore, the rating of EF-U has been assigned with estimated path width and length.

The wider storm

Surface low pressure system tracked across the North Dakota/South Dakota border creating an environment supporting the threat for low top supercells in Southeastern North Dakota into adjacent West Central Minnesota. Several low-top supercells developed and tracked along portions of the Minnesota Red River Valley. Portions of Norman, Polk, Becker, and Mahnomen counties saw multiple tornadoes. Large hail and damaging winds accompanied some of these storms, and flash flooding in some locations as well.

Began near Waubun (47.1563, -95.9559).
