NWS STORM PREDICTION CENTER NORMAN OK

AREAS AFFECTED...SOUTH CENTRAL THROUGH SERN TX AND PART OF WRN LA

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 141242Z - 141445Z

PROBABILITY OF WATCH ISSUANCE...40 PERCENT

SUMMARY...A THREAT FOR MAINLY ISOLATED HAIL IS POSSIBLE THROUGH THE
MORNING AS ADDITIONAL STORMS DEVELOP ALONG AND NORTH OF TWO SURFACE
BOUNDARIES ADVANCING SWD INTO SOUTH CENTRAL TO SERN TX AND WRN PARTS
OF LA.

DISCUSSION...REGIONAL RADAR IMAGERY SHOWED A STORM HAD DEVELOPED IN
SOUTHEAST TX AT THE INTERSECTION OF A SWD MOVING COLD FRONT AND A
CONVECTIVE OUTFLOW EXTENDING SWWD FROM NRN LA.  THIS STORM PRODUCED
0.88 INCH DIAMETER HAIL CLOSE TO 12Z IN HOUSTON COUNTY TX.
ADDITIONAL STORMS HAD DEVELOPED ALONG THE SWD MOVING COLD FRONT SWWD
INTO SOUTH CENTRAL TX.  THIS TREND IS EXPECTED TO PERSIST AS THE
COLD FRONT AND CONVECTIVE OUTFLOW BOUNDARY EACH ADVANCE SWD INTO A
CORRIDOR OF MODERATE INSTABILITY EXTENDING FROM SOUTH TO EAST TX
INTO LA.  EFFECTIVE BULK SHEAR AROUND 50 KT WILL SUPPORT ORGANIZED
STORMS.  GIVEN THE STEADY SWD MOVEMENT OF THE BOUNDARIES...STORMS
SHOULD CONTINUE TO BE UNDERCUT...BECOMING ELEVATED N OF THE
BOUNDARIES.
