   MESOSCALE DISCUSSION 1674
   NWS STORM PREDICTION CENTER NORMAN OK
   0313 PM CDT THU AUG 13 2015

   AREAS AFFECTED...SOUTH TEXAS

   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 

   VALID 132013Z - 132100Z

   CORRECTED FOR GRAPHIC

   PROBABILITY OF WATCH ISSUANCE...5 PERCENT

   SUMMARY...ISOLATED STRONG WIND GUSTS ARE POSSIBLE THROUGH SUNSET OR
   SHORTLY THEREAFTER IN THE DISCUSSION AREA.  A WW ISSUANCE WILL
   LIKELY NOT BE NEEDED GIVEN THE ISOLATED NATURE OF THE THREAT.

   DISCUSSION...SCATTERED THUNDERSTORMS ARE DEVELOPING/INCREASING IN
   INTENSITY AND COVERAGE ATTM.  DEEP SHEAR IS WEAK IN THIS
   REGION...BUT THE COMBINATION OF 1500-2000 J/KG MLCAPE AND A DEEPLY
   MIXED BOUNDARY LAYER WITH 30-35 F DEWPOINT DEPRESSION MAY SUPPORT A
   FEW WIND GUSTS APPROACHING SEVERE LEVELS IN/NEAR THE STRONGEST
   STORMS.  SLIGHTLY ENHANCED NELY MID-LEVEL FLOW /AROUND 25-30 KNOTS
   AT WIND PROFILERS AT GRK AND EWX/ MAY ALSO SUPPORT A LOCALLY STRONG
   WIND GUSTS AS STORMS TRANSFER THAT ADDITIONAL MOMENTUM TO THE
   SURFACE VIA DOWNDRAFTS.  THE THREAT WILL LIKELY REMAIN TOO ISOLATED
   FOR A WW ISSUANCE.
