May 29th brought a widespread severe weather outbreak to the eastern Texas Panhandle. Morning upper air analysis on the 29th showed a mid-level trough centered from Idaho to New Mexico with a low level closed low over Colorado and the western Oklahoma Panhandle. The lift provided by both of these large scale forcing mechanisms would easily overcome the capping inversion in place across the eastern Texas Panhandle by the early afternoon. At the surface, a dryline was positioned along the Eastern Plains of New Mexico during the morning hours before advancing eastward into the Texas Panhandle. By noon, this dryline had advanced to the central Texas Panhandle before stalling and provided a focusing point for convective initiation. Thunderstorms developed in an area of moderate elevated instability across the eastern Texas Panhandle which promoted rapid vertical growth. In the same area, vertical wind shear was ideal for the development of supercells. Along the dryline, discrete supercell thunderstorms developed shortly after the noon hour. These supercells produced 60+ mph gusts and hail up to the size of hen eggs.  As the afternoon progresses discrete supercells progressed to the east and merged into a squall line. Several more reports of 60+ mph gusts and large hail were received by the National Weather Service Office in Amarillo (Potter County) as this squall line progressed out of the Texas Panhandle and into western Oklahoma shortly after 5 pm CST.
