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.
