Episode Narrative Moisture increasing south of a warm front moved northward into western Texas. Instability increased east of a dry line, where thunderstorms were able to develop despite a strong cap. The thunderstorms moved east into western Oklahoma, but were fighting an even stronger cap as they moved east. The thunderstorms reached as far east as central Oklahoma before collapsing. Severe winds up to 70 mph and hail up to half-dollar size were reported with the thunderstorms. After the storms collapsed, they pushed out a gust front that had winds of 60 to 70 mph. Some damage was reported in and around the western sides of Oklahoma City.
Event Narrative An 18-wheeler jacknifed on Interstate 40 due to the strong winds. All lanes of traffic were blocked as a result. Monetary damages were estimated.
