A surface boundary stretching from southwest into north central North Dakota served as the primary focal point for thunderstorm development in an atmosphere of very high instability. Initially, large hail was the main threat, though a couple of tornadoes developed in an area of enhanced low level shear. Later, storms mainly developed along an old outflow boundary and were slow moving. This combined with a moisture rich atmosphere which led to a heavy rain threat, in addition to a hail and strong wind  threat. The heaviest rain fell over Sioux and Emmons counties, where there were multiple reports of over four inches of rain. In Sioux County, on the Standing Rock Nation, flash flooding from the heavy rain resulted in a section of BIA Road 3, locally known as the Kenel Road, being washed out at the crossing with Joe Bush Creek. The culvert washed out and the road collapsed. Four vehicles drove into the washout and resulted in two fatalities and two injuries. The largest hail reported in this episode was golf ball size, and fell in Divide, Morton, and Burleigh counties. The strongest wind gusts were 60 mph, and occurred in Wells and Divide counties.
