   AREAS AFFECTED...TX SOUTH PLAINS/TX PANHANDLE AND THE OK PANHANDLE
   
   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 
   
   VALID 262103Z - 262330Z
   
   CLUSTER OF TSTMS TO THE WNW OF LBB SHOULD BEGIN TO POSE A THREAT FOR
   MARGINALLY SVR HAIL/WIND SHORTLY. ADDITIONAL ISOLATED SVR TSTMS ARE
   POSSIBLE ALONG SEVERAL BOUNDARIES ACROSS THE OK/TX PANHANDLE AND NRN
   TX SOUTH PLAINS. WW IS NOT EXPECTED ATTM.
   
   LATEST SFC ANALYSIS SHOWS SEVERAL BOUNDARIES THAT WERE PROVIDING
   FOCUS FOR CONVECTIVE DEVELOPMENT ACROSS THE TX SOUTH PLAINS/TX
   PANHANDLE. A DRYLINE EXTENDS SWD FROM A SFC LOW NEAR GUYMON TO NEAR
   CVS. THE REMNANT SYNOPTIC FRONTAL BOUNDARY EXTENDS FROM NEAR
   PERRYTON TO 30 W OF CDS....WHILE A SECONDARY WEAK COLD FRONT EXTENDS
   FROM NEAR GUYMON TO NEAR LBL. WITH LITTLE REMAINING CINH OVER THE
   REGION...THESE BOUNDARIES SHOULD PROVIDE A FOCUS FOR ADDITIONAL TSTM
   DEVELOPMENT OVER THE NEXT COUPLE OF HOURS. RELATIVELY WEAK MID LEVEL
   FLOW /AROUND 20 KTS/ WILL LIMIT UPDRAFT STRENGTH...BUT MODERATE
   INSTABILITY /MLCAPE FROM 1000-1500 J/KG/ MAY SUPPORT A BRIEF SVR
   WIND/HAIL THREAT GIVEN STEEP LOW-MID LEVEL LAPSE RATES.
