On the evening of September 9th, a very subtle upper level system passed over the region, which allowed several thunderstorms to develop across the western to central Texas Panhandle. The atmosphere was strongly unstable for September standards, combined with moderate wind shear and high moisture content, and this proved to be conducive for storms to produce severe hail, winds, and localized fl...

A warm front lifted north and northwest across all but the Oklahoma Panhandle and the northwest Texas Panhandle while a sharpening dryline was located ove...

A surface trough near the New Mexico State Line helped spark late afternoon and evening thunderstorms across the central and south-central Texas Panhandle produced strong winds, hail and very heavy rains. The West Texas Mesonet station 12 miles southwest of Claude in Armstrong County measured...

With PWAT values in the 75th percentile based off climatology upper air obs, the atmosphere was very moist to support heavy rainfall. Residual outflow boundaries across the western TX Panhandle generated storms later in the afternoon on the 10th with SBCAPE of around 15...
