   The severe weather threat for Severe Thunderstorm Watch 134
   continues.

   SUMMARY...Storms ongoing in a line from southeast Colorado, far
   western Oklahoma Panhandle, and the along the northern border of New
   Mexico and the Texas Panhandle will move into an area of greater
   surface moisture and instability over the next few hours. Severe
   wind gust and hail threats will increase as this occurs.

   DISCUSSION...Current surface analysis show a weak low pressure
   center in the far western Texas Panhandle with a dryline extending
   southeastward from DUX to CDS. A warm front is evident in the north
   Texas Panhandle eastward into northern Oklahoma. Storms have been
   ongoing in western portions of WW 134. Over the last hour or so,
   radar trends show that storms have taken on more of a linear mode.
   As these storms progress east, they will encounter a moist, unstable
   airmass characterized by mid- to upper-60s dewpoints and surface
   temperatures into the 90s. MLCAPE values will be anywhere from 2000
   to 3500 J/kg. Storm severity is expected to increase in the next few
   hours. Some uncertainty exists as to the southern extent of this
   line of storms. Some signs of cumulus development have been evident
   on visible satellite imagery near DUX. Should further development
   occur, possible watch extensions in area may be needed along the
   southern edge of WW 134.
