  AREAS AFFECTED...PORTIONS OF N TX
 
  CONCERNING...TORNADO WATCH 149...
 
  VALID 110034Z - 110130Z
 
  THE SEVERE WEATHER THREAT FOR TORNADO WATCH 149 CONTINUES.
 
  TORNADO THREAT WILL CONTINUE ACROSS WW 149 THE NEXT COUPLE OF HOURS.
 
 
  THUNDERSTORM DEVELOPMENT HAS BEEN SLOW AND SO FAR RELATIVELY
  ISOLATED FROM THE RED RIVER SWD TOWARD DYS ALONG DRYLINE. CAPPING
  INVERSION APPEARS TO BE LIMITING MORE WIDESPREAD DEVELOPMENT WITH
  THE STRONGEST CELL LOCATED OVER SRN YOUNG COUNTY. GIVEN A STRONGER
  CAP FURTHER EWD...ANY STORMS THAT DEVELOP MAYBE HAVE A HARD TIME
  BECOMING SFC BASED AND LARGE HAIL AND STRONG WINDS MAY BE POSSIBLE.
  HOWEVER...MUCAPE AROUND 3000-4000 J/KG AND EFFECTIVE BULK SHEAR OF
  50-65 KT WILL ALLOW ANY SFC BASED STORMS TO CONTINUE TO POSE A
  TORNADO THREAT. AFTER SUNSET...BOTH CAPE AND LOW LEVEL SHEAR BEGIN
  TO DECREASE.
