AREAS AFFECTED...TX GULF COAST

CONCERNING...SEVERE THUNDERSTORM WATCH 201...

VALID 240712Z - 240845Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 201
CONTINUES.

SUMMARY...STRONG GUSTS CAPABLE OF ISOLATED WIND DAMAGE WILL REMAIN
POSSIBLE ALONG THE LEADING EDGE OF A QLCS MOVING NE FROM THE CORPUS
CHRISTI METRO AREA AND E TOWARDS THE BROWNSVILLE METRO AREA. NEW WW
ISSUANCE IS UNLIKELY DOWNSTREAM BUT LOCAL WFO EXTENSION IS POSSIBLE.

DISCUSSION...MORE INTENSE PORTIONS OF A QLCS ALONG THE LOWER TX GULF
COAST APPEAR TO BE EVOLVING NEWD FROM THE CRP METRO AREA AHEAD OF AN
MCV CENTERED OVER MCMULLEN AND LIVE OAK COUNTIES...WITH A MORE
EWD-PROPAGATING COMPONENT ACROSS DEEP S TX. A 44 KT WIND GUST WAS
MEASURED AT KCRP AND 40 KT AT KHRL IN THE PAST HOUR. THESE STRONG
GUSTS SHOULD BE CAPABLE OF ISOLATED WIND DAMAGE.

WAA-DRIVEN CONVECTION FORMING OVER THE MIDDLE TX GULF COAST SHOULD
FOSTER MERGING UPDRAFTS AHEAD OF THE MCV AND PERSISTENCE OF THE QLCS
FARTHER UP THE TX COAST THIS MORNING. WITH PREDOMINATELY MERIDIONAL
DEEP-LAYER FLOW PARALLELING THE ORIENTATION OF THE LINE...THE
OVERALL SEVERE RISK DOES NOT APPEAR LIKELY TO INCREASE AND SHOULD
REMAIN SPATIALLY CONFINED NEAR THE COAST.
