CONCERNING...SEVERE THUNDERSTORM WATCH 63...

VALID 061831Z - 061930Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 63
CONTINUES.

SUMMARY...ISOLATED HAIL THREAT CONTINUES ACROSS EAST TX AND LA.

DISCUSSION...SFC WARM FRONT IS GRADUALLY ADVANCING INLAND ALONG THE
UPPER TX COAST.  THIS BOUNDARY APPEARS TO BE LIFTING NORTH PARTLY IN
RESPONSE TO APPROACHING SHORT-WAVE TROUGH.  ADDITIONALLY...REGIONAL
RADAR DATA SUGGESTS A WEAK MCV/VORT MAY BE EVOLVING NE OF ACT PER
WEAK MID LEVEL SUBSIDENCE/DRYING SPREADING ACROSS SCNTRL TX.  IN
RESPONSE...LOW LEVEL FLOW IS BEGINNING TO VEER ACROSS SERN TX AND
MOIST/BUOYANT WARM SECTOR SHOULD CONTINUE TO RETURN ACROSS SERN
TX/SRN LA.

WHILE ISOLATED HAIL MAY ACCOMPANY THE STRONGEST ELEVATED
UPDRAFTS...GREATER CONCERN WILL BE WITH NEAR-SFC BASED CONVECTION
THAT EVOLVES LATER THIS AFTERNOON ALONG/SOUTH OF WARM FRONT.  GIVEN
THE STRONG SHEAR NOTED ACROSS THIS REGION THE THREAT FOR TORNADOES
WILL INCREASE AS SUPERCELLS ROOT INTO HIGHER THETA-E BOUNDARY LAYER.
TORNADO WATCH WILL LIKELY BE WARRANTED LATER TO ACCOUNT FOR THIS
THREAT.
