   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 546
   CONTINUES.
   
   ...SEVERE THUNDERSTORM WATCH MAY BE NEEDED ACROSS PARTS OF NWRN
   TX...
   
   REMNANT MCV AND ASSOCIATED MID LEVEL CONVECTIVE DEBRIS IS SPREADING
   ACROSS ECNTRL NM INTO THE WRN TX PANHANDLE.  ALONG THE LEADING EDGE
   OF THIS THICKER CLOUD CANOPY THUNDERSTORMS HAVE RECENTLY
   DEVELOPED...JUST OFF THE CAP ROCK FROM SE OF LBB TO WHEELER COUNTY. 
   SFC TEMPERATURES HAVE WARMED AOA 100F WITHIN VEERED...BUT MOIST LOW
   LEVEL PRE-FRONTAL FLOW.  LATEST THINKING IS THIS ACTIVITY SHOULD
   GRADUALLY EXPAND IN AREAL COVERAGE/INTENSITY OVER THE NEXT FEW
   HOURS.  GIVEN THE LARGE TEMP/DEW POINT SPREADS IT APPEARS STRONG
   WINDS WILL BE THE PRIMARY SEVERE THREAT.
