AREAS AFFECTED...CNTRL AND N CNTRL TX

CONCERNING...TORNADO WATCH 121...

VALID 262251Z - 270015Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 121 CONTINUES.

SUMMARY...SCATTERED SUPERCELLS WILL PERSIST THROUGH LATE
EVENING...WITH A CONTINUED RISK FOR TORNADOES...VERY LARGE
HAIL...AND DAMAGING GUSTS.  A STRONG TORNADO WILL BE POSSIBLE LATER
THIS EVENING AS LOW-LEVEL MOISTURE AND SHEAR INCREASE.

DISCUSSION...THERE HAS BEEN SOME MIXING OF LOW-LEVEL MOISTURE ACROSS
CENTRAL TX...TO THE S OF THE WEAKENING SUPERCELL IN ERATH COUNTY.
THE MIXING HAS RESULTED IN SOME REDUCTION IN BUOYANCY AND HIGHER LCL
HEIGHTS...BUT OBSERVATIONS A BIT FARTHER S SHOW MOISTURE RECOVERING
AS SURFACE TEMPERATURES REMAIN WELL INTO THE 80S.  DEWPOINTS ARE
EXPECTED TO RECOVER INTO THE MID 60S THIS EVENING INTO THE ZONE OF
BACKED WINDS WITH THE RESIDUAL OUTFLOW/DIFFERENTIAL HEATING BOUNDARY
FROM ABOUT WACO TO BROWNWOOD.  ALSO...LOW-LEVEL SHEAR WILL INCREASE
IN RESPONSE TO THE SYNOPTIC WAVE EMERGING OVER W TX...WHICH SHOULD
SUPPORT A REJUVENATION OF THE TORNADO RISK BY ABOUT 00-01Z.  IN THE
INTERIM...NEW STORMS WILL LIKELY DEVELOP NEAR TRIPLE POINT CLOSE TO
BROWNWOOD...WITH A CONTINUED RISK FOR VERY LARGE HAIL AND DAMAGING
GUSTS.
