Thunderstorms developed along and east of a dry line over the eastern Texas panhandle. The atmosphere was extremely unstable and wind shear was more than sufficient to support severe thunderstorms, including supercell thunderstorms. Showers and thunderstorms that developed early in the day, gave way to more severe thunderstorms by mid afternoon. Severe weather of all types occurred, with numerous locations receiving very large hail. Tornadoes were also reported in Roger Mills and Ellis counties, with some significant damage reported. Flooding also became an issue as some of the same areas received heavy rainfall for the second day in a row. Monetary damages were estimated.
