0403 PM CDT WED SEP 26 2007
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.
