EF2 tornado in Ellis County, Oklahoma

This tornado developed 4 miles north-northeast of Roll in northern Roger Mills County and crossed the Canadian River into southern Ellis County at 9:36 pm CDT. Two houses and two mobile homes were destroyed in the Packsaddle area of southern Ellis County to the east of US Highway 283 (about 18 miles south-southwest of Harmon), and a roof was removed from another mobile home. At least one of these homes suffered a complete removal of the roof and some damage to the exterior walls. Several cars were damaged or destroyed, as well as trees and power lines. Monetary values were estimated.

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.
