Scattered thunderstorms developed this afternoon along the edge of the Caprock in Briscoe and Floyd Counties.  Very strong instability compensated for weak wind shear and allowed a few of these storms to become supercells and produce very large hail as they tracked slowly southeastward.  More numerous storms then surged south from the Texas Panhandle and resulted in a large, southward-moving storm complex that affected much of the South Plains and Rolling Plains through the evening.  This complex of storms produced a handful of severe wind gusts and a large wall of dirt (haboob) that reduced visibilities to near zero for a few minutes at the Lubbock International Airport.
