An upper trough was over the region with abundant low-level moisture present across West Texas. A cold front was moving southward from southwest Oklahoma and there was a nearly stationary outflow boundary across Ector County from storms the previous day. Rain and thunderstorms were across the Permian Basin during the morning hours which resulted in hail across portions of the area. High instability due to clearing skies allowed for severe thunderstorms to develop across the southern Permian Basin and in Pecos County during the afternoon hours. These storms produced large hail and tornadoes. Flash flooding developed across portions of the Permian Basin during the early afternoon hours.
