A strong shortwave trough over the southwestern states moved east northeastward toward the central and southern Plains as another low pressure system dropped into the Pacific Northwest. A dryline set up and high dewpoints were in the area by mid-afternoon, resulting in even stronger CAPE. This created severe hail and wind across the counties mentioned above, as well as tornadoes in Clark, Ford, and Pawnee counties.
