   AREAS AFFECTED...PORTIONS TX/OK PANHANDLES...TX SOUTH-PLAINS
   REGION...WRN OK...SWRN KS.
   
   CONCERNING...SEVERE THUNDERSTORM WATCH 757...759...
   
   VALID 100127Z - 100330Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
   757...759...CONTINUES.
   
   SVR GUST POTENTIAL STILL EXISTS WITH TSTMS ALONG AND AHEAD OF
   EXPANDING OUTFLOW EDGE ACROSS WW REGION...BUT SHOULD DIMINISH
   THROUGH REMAINDER EVENING AS PRE-OUTFLOW/PRECONVECTIVE BOUNDARY
   LAYER DIABATICALLY STABILIZES.  MODIFIED RAOBS AND RUC SOUNDINGS
   SUGGEST RELATIVE MIN IN MLCINH..IN CORRIDOR LOCATED ALONG AND JUST N
   OF RESIDUAL OUTFLOW BOUNDARY FROM PRIOR MORNING/OVERNIGHT
   CONVECTION.  THIS BOUNDARY IS LIFTING NWD 10-15 KT ACROSS SERN
   PANHANDLE AND SW OK...WITH MOIST AXIS TO ITS N. 
   HOWEVER...DEFINITION OF BOUNDARY SHOULD WEAKEN WITH TIME...AND
   DIABATIC SFC COOLING WILL STRENGTHEN MLCINH.  AMIDST WEAK MID-UPPER
   FLOW...PROBABILITY APPEARS VERY LOW OF CONVECTION OVER ERN TX
   PANHANDLE REGAINING ORGANIZATION AS IT MOVES INTO OK. 
   MEANWHILE...SVR HAIL PRODUCING TSTMS OVER OK PANHANDLE SHOULD MOVE
   INTO SRN PORTIONS WW 759...WITH POTENTIAL FOR DAMAGING GUSTS AND
   ISOLATED LARGE HAIL REMAINING UNTIL WELL-MIXED SUBCLOUD LAYER
   EVIDENT IN 00Z DDC RAOB DIABATICALLY STABILIZES SUBSTANTIALLY FROM
   BOTTOM UP.
   
   AS FOR CURRENTLY POSTCONVECTIVE REGION OVER MUCH OF CENTRAL/WRN
   PANHANDLES...ISOLATED TO WIDELY SCATTERED TSTMS MAY DEVELOP ATOP
   OUTFLOW POOL...WHERE ISENTROPIC ASCENT TO LFC IS POSSIBLE IN
   ASSOCIATION WITH WRN LIMB OF INTENSIFYING SRN-PLAINS LLJ.  MAIN
   CONCERN WOULD BE HAIL.  WIND THREAT FROM ANY SUCH CONVECTION WOULD
   BE LIMITED BY NEAR-SFC STABILITY.
