   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 310
   CONTINUES.

   SUMMARY...THE THREAT FOR A FEW STRONG WIND GUSTS AND/OR LARGE HAIL
   REPORTS PERSISTS...WITH THE GREATEST POTENTIAL LIKELY ACROSS THE WRN
   HALF OF THE WATCH.

   DISCUSSION...A S/SWWD-PROGRESSING GRAVITY WAVE APPEARS TO HAVE AIDED
   CONVECTIVE INITIATION OVER PORTIONS OF THE OK/TX PANHANDLES THIS
   AFTERNOON. ALTHOUGH CELLS HAVE GENERALLY LACKED SUSTAINED/ORGANIZED
   CORES ALOFT /LIKELY DUE TO SUB-OPTIMAL SHEAR AND LACK OF STRONGER
   FORCING FOR ASCENT/...AMPLE MID-LEVEL BUOYANCY AND DEEPLY MIXED LOW
   LEVELS SHOULD CONTINUE TO OFFER A THREAT FOR A FEW LARGE HAIL
   REPORTS AND/OR STRONG WIND GUSTS WITH MORE ROBUST UPDRAFTS.
   THUS...THE SEVERE THREAT CONTINUES ACROSS THE WATCH...ESPECIALLY THE
   APPROXIMATE WRN HALF...WHERE BETTER LOW-LEVEL CONVERGENCE AND
   SOMEWHAT MORE FAVORABLE EFFECTIVE SHEAR EXIST. ADDITIONALLY...THE
   WIND THREAT WILL BE ENHANCED WHERE ANY COLD-POOL MERGERS FAVOR
   UPSCALE GROWTH LATE THIS AFTERNOON INTO THIS EVENING.
