AREAS AFFECTED...S CNTRL THROUGH SERN TX

CONCERNING...TORNADO WATCH 231...

VALID 081944Z - 082145Z

THREAT FOR ISOLATED TORNADOES EXPECTED TO PERSIST INTO THE EARLY
EVENING WITH BEST THREAT IN THE AREA BETWEEN VICTORIA AND HOUSTON
NEXT COUPLE HOURS. OTHERWISE...LARGE HAIL...ISOLATED DAMAGING WIND
AND VERY HEAVY RAIN WILL REMAIN THE PRIMARY THREATS WITH THE
STRONGER STORMS. 

THE OUTFLOW BOUNDARY ASSOCIATED WITH THE LARGE MCS CURRENTLY EXTENDS
FROM SERN TX JUST N OF HOUSTON WWD TO NW OF VICTORIA TO S OF HONDO.
MOST ACTIVE PORTION OF THE BOUNDARY CONTINUES TO BE FROM VICTORIA TO
NEAR HOUSTON. STORMS CONTINUE DEVELOPING IN VICINITY OF AND JUST S
OF THE OUTFLOW BOUNDARY AS IT CONTINUES TO SETTLE SLOWLY SWD. VWPS
FROM CORPUS CHRISTI AND HOUSTON SHOW ESELY LOW LEVEL WINDS WITH 0-1
KM STORM RELATIVE HELICITIES FROM 200 TO 250 M2/S2 AND 0-6 KM DEEP
SHEAR OF 40+ KT WITHIN THE MODERATELY UNSTABLE WARM SECTOR.
THEREFORE THE ENVIRONMENT CONTINUES TO SUPPORT ORGANIZED STORMS
INCLUDING THE THREAT OF SUPERCELLS CAPABLE OF PRODUCING ISOLATED
LARGE HAIL AND TORNADOES. BOW ECHO STRUCTURES ALSO REMAIN POSSIBLE.
BEST CHANCE FOR ISOLATED TORNADOES WILL BE WITH STORMS DEVELOPING
NEAR OR JUST S OF THE BOUNDARY. THE STORMS WILL TEND TO BECOME
ELEVATED AS THEY MOVE N OF THE OUTFLOW BOUNDARY...BUT MAY STILL
REMAIN CAPABLE OF PRODUCING HAIL.
