A tornado touched down in southern Bowman County, North Dakota and moved south into South Dakota west of US Highway 85. The total path length was almost four miles, and was on the ground over a mile in South Dakota. It caused no damage in Harding County, but did damage buildings on a farm about a mile north of the state line estimated around 100 mph and corresponding to EF1. Additional information on the first portion of this tornado is in the North Dakota, Central and West section of this Storm Data report.
