A cold front that moved through Oklahoma on the 8th began lifting back north during the day on the 9th. North of the front, temperatures were cool with readings in the 40s and 50s. South of the front, temperatures eventually warmed into the 60s and 70s. Thunderstorms were ongoing over western Texas during the early morning hours as a strong upper level storm system was moving into the southern plains. These thunderstorms moved east into Oklahoma during the mid to late morning hours and continued into the early afternoon. The thunderstorms were generally non-severe, but a thunderstorms over Tillman county briefly became severe with quarter size hail. The warm front continued to lift north with precipitation becoming widespread and heavy along and north of it. South of the front, clearing skies were allowing for very unstable conditions to develop. Severe thunderstorms developed over the southeast half of Oklahoma and moved northeast through the evening and overnight hours. Several of the thunderstorms became supercells, with large hail and damaging winds. The storms congealed into a larger complex with embedded severe storms later in the evening. Heavy rain became another concern as the night progressed. Numerous locations picked up several inches of rain by the 10th, with several reports of flash flooding. Monetary damages were estimated.
