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 This tornado developed in northern Roger Mills County 4 miles north of Dempsey and moved north-northeast crossing into Ellis County about 16 miles south of Arnett. No damage was reported in this rural area of the county, although the tornado was reported as a wide tornado at times. As the tornado approached U.S. Highway 283, it was reported to be a well-developed cone shaped tornado with occasional multiple vorticies. Tree limbs were reported downed where it crossed U.S. Highway 283. The tornado dissipated about a mile after crossing the highway. Monetary damages were estimated.
