What the National Weather Service wrote

A tornado touched down roughly 4.5 miles southeast of Mound City, SD in open crop and grassland. Photo and video evidence of the tornado was documented. The track was also noted on high resolution satellite imagery.

The wider storm

An isolated, strong storm moving from between just north of Mobridge to just southwest of Mound City generated a strong tornado that was well documented by storm chasers and spotters. Additional, weaker satellite tornadoes and embedded vortices within the main tornado were observed during the 30 minute duration this tornado was on the ground. This resulted in sporadic, intense areas of multi-directional tornado damage, as well as areas of very broad uniform damage. After the main tornado had dissipated, a distinct additional tornado developed southeast of Mound City lasting a few minutes.

Began near Mound City (45.6884, -99.9942).
