.DISCUSSION...
A CLUSTER OF THUNDERSTORMS ACROSS WEST CENTRAL TEXAS/NORTH OF THE
HILL COUNTRY WILL CONTINUE TO MOVE S/SW-WRD INTO THE HILL COUNTRY
OVER THE NEXT HOUR OR SO. SOME OF THESE THUNDERSTORMS MAY PULSE TO
SEVERE LEVELS...BUT OVERALL THREAT AND COVERAGE OF SEVERE STORMS
IS TOO LOW TO WARRANT EXTENDING THE SEVERE THUNDERSTORM WATCH.
THERE IS STILL THE POTENTIAL FOR THESE THUNDERSTORMS TO PRODUCE
HEAVY RAINFALL...WHICH COULD BE INTENSE ENOUGH TO CAUSE MINOR
FLOODING OF CREEKS/STREAMS/DRAINAGE AREAS. ASIDE FROM TWEAKS DUE
TO THE WATCH...HAVE INCREASED POPS ACROSS THE WESTERN HILL
COUNTRY/SOUTHERN EDWARDS PLATEAU THROUGH ABOUT 06Z/1 AM CDT AND
EXPANDED MENTION OF SLIGHT CHANCE ACROSS THE SOUTHEASTERN HALF OF
THE CWA INTO THE WEE HOURS OF THE MORNING IN CASE THE STORMS
LINGER PAST 06Z. NEW ZONES WILL BE OUT SHORTLY.

KECU TO KHYI TO K3T5. SOME OF THE THUNDERSTORMS HAVE PRODUCED
LARGE HAIL AND DAMAGING WINDS. THESE STORMS WILL WEAKEN THROUGH

POSSIBILITY THAT TAF AMD MAY NEED TO BE ISSUED THIS EVENING AS THE
SITUATION PROGRESSES.

LATER TONIGHT...LOW STRATUS WILL DEVELOP OVERNIGHT AND PROGRESS
WESTWARD THROUGH THE EARLY MORNING HOURS. AN APPROACHING COLD
FRONT WILL SEND DRIER N-NELY SFC WINDS INTO THE AREA...ENABLING
