   Areas affected...west Texas

   Concerning...Severe Thunderstorm Watch 132...133...

   Valid 052314Z - 060045Z

   The severe weather threat for Severe Thunderstorm Watch 132, 133

   SUMMARY...Isolated supercells capable of producing very large hail,
   locally damaging wind gusts and isolated tornadoes will persist next
   few hours.

   DISCUSSION...Early this evening isolated storms that developed along
   the dryline have matured across west Texas with several supercells
   in progress. The atmosphere in this region is strongly unstable with
   2000-3000 J/kg MLCAPE, steep mid level lapse rates and
   effective-bulk shear of 40-50 kt. The Lubbock VWP adjusted for
   southeast winds south of the outflow boundary indicate sufficient
   0-1 km storm relative helicity for low-level mesocyclones, and
   further enlargement of the hodograph is likely as the low-level jet
   increases. These factors along with unimpeded moist inflow suggest
   the supercell south of Lubbock might remain capable of producing
   occasional tornadoes during the next hour. With time, storm and
   outflow boundary interactions may contribute to some upscale growth
   to lines and clusters as activity develops east.
