   MESOSCALE DISCUSSION 1593
   NWS STORM PREDICTION CENTER NORMAN OK
   0552 PM CDT THU AUG 25 2016

   AREAS AFFECTED...PARTS OF THE TEXAS PANHANDLE AND WRN OKLAHOMA

   CONCERNING...SEVERE THUNDERSTORM WATCH 457...

   VALID 252252Z - 260015Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 457
   CONTINUES.

   SUMMARY...THREAT FOR MAINLY MARGINALLY SEVERE HAIL AND LOCALLY
   STRONG SURFACE GUSTS WILL CONTINUE IN STRONGEST THUNDERSTORM
   ACTIVITY THROUGH EARLY EVENING.

   DISCUSSION...THUNDERSTORMS HAVE BECOME INCREASINGLY NUMEROUS THE
   PAST COUPLE OF HOURS ACROSS PARTS OF THE TEXAS PANHANDLE INTO
   WESTERN OKLAHOMA.  THIS APPEARS GENERALLY TO THE COOL SIDE OF A WEAK
   FRONTAL ZONE...WHERE PRECIPITABLE WATER CONTENT AND INSTABILITY
   APPEARS MAXIMIZED.  MORE PRONOUNCED TURNING OF LOW THROUGH MID-LEVEL
   WIND FIELDS IS ALSO CONTRIBUTING TO FAIRLY STRONG SHEAR BENEATH 30
   KT SOUTHWESTERLY 500 MB FLOW.  THIS MAY BE CONTRIBUTING TO AT LEAST
   SHORT-LIVED SUPERCELL STRUCTURES...ACCOMPANIED MAINLY BY THE RISK
   FOR MARGINALLY SEVERE HAIL AND LOCALIZED STRONG WIND GUSTS.  THIS
   THREAT MAY CONTINUE INTO THE 00-02Z TIME FRAME...BEFORE THE
   STABILIZING INFLUENCE OF ONGOING CONVECTION AND DIURNAL BOUNDARY
   LAYER COOLING PROGRESSES.
