The afternoon and evening of the 26th brought widespread severe storms to the South Plains. An approaching upper level short wave combined with residual outflow boundaries, a dryline, and strong instability and shear to create this widespread severe weather. Initial thunderstorm development occurred in the southwestern South Plains and adjacent Permian Basin and southeastern New Mexico along residual outflow boundary from previous day convection. Sufficient deep layer shear in the atmosphere caused these initial thunderstorms to rotate and become supercells. Numerous storm splits occurred with these storms generating heavy rainfall, damaging winds, and large hail. The largest hail observed was from a left-moving supercell at Muleshoe Wildlife Refuge (Bailey County). At the same time this was occurring, scattered thunderstorms developed in the higher terrain of eastern New Mexico. These storms slowly propagated their way into West Texas during the evening hours just as the initial thunderstorm development began to wane. The thunderstorms quickly grew upscale into a line of storms that swept across the South Plains and into the western Rolling Plains during the evening hours. This second round of thunderstorms produced widespread severe winds with wind gusts up to 76 mph.
