   AREAS AFFECTED...SERN CO...NERN NM...WRN OK PNHDL AND PARTS OF TX
   PNHDL
   
   CONCERNING...SEVERE THUNDERSTORM WATCH 420...
   
   VALID 232232Z - 240000Z
   
   STRONGEST SUSTAINED TSTM THAT DEVELOPED OVER THE VOLCANO FIELDS OF
   NERN NM IS BEGINNING TO MOVE INTO THE WRN OK PNHDL.  THIS TSTM
   APPEARS TO BE INGESTING MORE UNSTABLE PARCELS RESIDING IN THE
   BOUNDARY LAYER GIVEN ITS LONGEVITY.  RICH BOUNDARY LAYER MOISTURE
   WITH DEW POINTS IN THE MID 60S EXISTS DOWNSTREAM AND PRIND THAT
   TSTMS WILL CONTINUE TO MOVE ESEWD INTO THE OK PNHDL AND PARTS OF THE
   WRN/NRN TX PNHDL OVER THE NEXT COUPLE OF HOURS.  THIS AREA RESIDES
   ON SRN PERIPHERY OF STRONGER MIDLEVEL FLOW AND VERTICAL SHEAR IS
   JUST ENOUGH TO SUPPORT SUPERCELLS WITH LARGE HAIL THE MAIN THREAT.
   
   OTHERWISE...ACROSS SERN CO...OUTFLOW BOUNDARY EMANATING FROM THE
   NERN CO TSTMS IS SPREADING NWWD INTO SERN CO.  MOIST UPSLOPE FLOW
   AUGMENTED BY THIS OUTFLOW MAY AID IN TSTM GENERATION ACROSS THE
   REGION IN THE NEXT COUPLE OF HOURS IF CAP CAN BE OVERCOME.
   
   FARTHER SOUTH...TSTMS HAVE RECENTLY DEVELOPED ALONG DRYLINE SITUATED
   ALONG THE NM/TX BORDER AREA.  DEEP LAYER SHEAR IS WEAKER THAN
   FARTHER SOUTH AND MAINLY MULTICELL CLUSTERS ARE EXPECTED. 
   HOWEVER...GIVEN THE DEEPLY MIXED BOUNDARY LAYER...POTENTIAL WILL
   EXIST FOR ISOLD DAMAGING WINDS AND PERHAPS SEVERE HAIL.
