   INCREASE IN COVERAGE AND INTENSITY BY MID-LATE AFTERNOON ACROSS W
   CENTRAL TX AND SE NM IN ADVANCE OF THE TROUGH...WHERE SURFACE
   HEATING IN CLOUD BREAKS AND DEWPOINTS OF 56-60 F ARE CONTRIBUTING TO
   MLCAPE VALUES NEAR 1000 J/KG.  VERTICAL SHEAR WILL BE SUFFICIENT FOR
   A FEW SUPERCELLS WHICH WILL LOCALLY ENHANCE THE HAIL THREAT...WHILE
   CONVECTION SHOULD EVENTUALLY GROW UPSCALE INTO AN EXTENSIVE N-S BAND
