   Areas affected...Portions of west into western north TX

   Concerning...Severe Thunderstorm Watch 107...

   Valid 272250Z - 272345Z

   The severe weather threat for Severe Thunderstorm Watch 107
   continues.

   SUMMARY...Initial threat for large hail will probably transition to
   more of a damaging wind threat this evening as storms move
   east-southeastward across Severe Thunderstorm Watch 107. A more
   isolated hail/wind threat near Midland, TX will probably not require
   additional watch issuance.

   DISCUSSION...Recent radar imagery shows a few supercells have
   developed across west TX to the east of Lubbock in the vicinity of a
   weak cold front. Multiple reports of 1 to 1.5 inch hail have been
   received from these storms as effective bulk shear of 45-50 kt acts
   to organize updrafts. Storm interactions/mergers are occurring
   across Dickens County and vicinity. Large surface
   temperature-dewpoint spreads to the south of the front and steep
   low-level lapse rates should foster a favorable environment for
   damaging winds, which may gradually become the primary threat this
   evening if storms can grow upscale. A more isolated hail/wind threat
   may develop south of the ongoing convection along a surface
   trough/dryline near and just north of Midland. This risk will likely
   remain too isolated to warrant additional watch issuance in this
   area.
