   Areas affected...Far West Texas

   Concerning...Severe potential...Watch possible 

   Valid 262216Z - 262345Z

   Probability of Watch Issuance...40 percent

   SUMMARY...A severe thunderstorm watch may be needed as a pair of
   supercells have developed along the dryline in the vicinity of the
   Trans-Pecos mountains. These storms will be capable of 2.00+ inch
   hail and 60-70 MPH wind gusts, though a tornado cannot be ruled out.

   DISCUSSION...Supercell thunderstorms have developed along a dryline
   in the vicinity of the Trans-Pecos mountains, with 2500+ J/kg of
   MLCAPE to the east, and 45-50 kts of deep layer shear. Given
   boundary perpendicular shear vectors, supercell storm mode is likely
   to be maintained into the early evening hours. Primarily
   straight-line hodographs should favor splitting of supercells
   capable of large hail and damaging winds, particularly with left
   splits. Some meager low-level curvature of the hodograph from
   forecast proximity profiles, along with ML LCL heights around
   1100-1300 meters, could support tornado occurrence as well,
   especially as the nocturnal low-level jet increases low-level shear
   into the evening. However, the primary threat will be for 2.00+ inch
   hail and 60-70 MPH winds.
