Overview

A compact upper level disturbance and weak frontal boundary supported storm development in what turned out to be a weakly capped environment. Moderate instability and shear supported a few high based supercell structures which moved southeast from near Dalhart all the way down to Wellington. Very large hail, strong winds and a few funnels were reported with these storms. The largest hail was reported in Pampa (slightly larger than baseballs), and the strongest wind was reported in Borger (86 mph). Wind damage was also reported in Borger and Wellington. A more isolated storm also formed near Canyon which produced some hail up to ping pong ball size. A brief land spout tornado also occurred west southwest of Pampa.
