AREAS AFFECTED...ERN TX...LA

CONCERNING...SEVERE THUNDERSTORM WATCH 253...

VALID 260442Z - 260545Z

STORMS CONTINUE TO INCREASE ALONG COLD FRONT MOVING SLOWLY ACROSS LA
AND THE UPPER TX COAST LATE TONIGHT. MOIST AND MARGINALLY UNSTABLE
CONDITIONS IN POST-MCS AIR MASS ACROSS LA SHOULD CONTINUE TO SUPPORT
MODEST/STRONG UPDRAFTS GIVEN PERSISTENT LIFT ALONG THE ADVANCING
FRONTAL CIRCULATION. ADEQUATE DEEP SHEAR OF 30-45KT OBSERVED ON
WINFIELD AND DE QUEEN WIND PROFILERS SUGGESTS THAT SUPERCELL
STRUCTURE REMAINS A POSSIBILITY WITH THIS CONVECTION. A COUPLE OF
HAIL/WIND EVENTS COULD OCCUR AS ACTIVITY DEVELOPS SLOWLY EAST TOWARD
THE MS RIVER THROUGH THE NIGHT.
