Episode Narrative An upper level storm system moved slowly into south central Colorado during the afternoon. A dry line had become established and was located along the Oklahoma and Texas panhandle border. Also, favorable upper level winds were rotating around the upper level storm system, crossing the dryline over western Oklahoma. As the afternoon progressed, convergence along the dryline became maximized over this area. Thunderstorms developed during the afternoon hours and they quickly became supercells. Two of the supercells produced several tornadoes. The northern tornadic storm produced five tornadoes from southwest of Roll to just east of Arnett. The southern tornadic storm also produced five tornadoes in Oklahoma from near Sweetwater to near Sharon. Large hail was also observed. The supercells moved northeast out of Oklahoma during the late evening hours. Monetary values for the tornado damage were estimated.
Event Narrative A tornado developed in far southeastern Ellis County about 9 miles east-southeast of Harmon. It moved east-northeast into Dewey County near U.S. Highway 60 and eventually moved into Woodward County before it dissipated east-northeast of Sharon. There was no known damage in Ellis County. This was the beginning of the fifth and final tornado in Oklahoma from the southern tornadic supercell.
