AREAS AFFECTED...EXTREME NERN TX AND SRN AR

CONCERNING...SEVERE THUNDERSTORM WATCH 793...

VALID 152229Z - 152330Z

SEVERE THUNDERSTORM WATCH #793 IS SET TO EXPIRE AT 00Z.  ANOTHER WW
WILL NOT BE ISSUED.

TSTMS CONTINUE TO TRAVERSE EWD ACROSS SRN AR AND EXTREME NERN
TX...ALONG/AHEAD OF THE PRIMARY COLD FRONT.  UPDRAFTS HAVE NOT BEEN
PARTICULARLY ORGANIZED GIVEN THE RELATIVELY WARM LAYER NOTED BETWEEN
H7-H5 AND THE FACT THAT THE MAIN SHORTWAVE TROUGH WAS EJECTING
TOWARD THE MID-MS VLY. STRONGER STORMS HAVE BEEN LOCATED WELL WEST
OF THE REGION WHERE SLIGHTLY STEEPER MID-TROPOSPHERIC LAPSE RATES
EXIST.

CURRENT TSTMS SHOULD GRADUALLY WEAKEN AND THE THREAT FOR ORGANIZED
SEVERE WEATHER IS DIMINISHING RAPIDLY. THUS...THE WW WILL EXPIRE AT
00Z WITH NO PLAN TO REISSUE.
