   Areas affected...southwestern Oklahoma through portions of west and
   central Texas

   Concerning...Severe Thunderstorm Watch 44...

   Valid 222225Z - 222330Z

   The severe weather threat for Severe Thunderstorm Watch 44
   continues.

   SUMMARY...The severe threat continues across WW 44.  Downstream
   watches may be considered across north and/or central Texas and
   vicinity over the next couple of hours.

   DISCUSSION...Recent radar trends indicate a sharpening of convective
   bands/linear segments across ongoing portions of WW 44.  Strong to
   severe wind gusts have been reported with the linear segment
   progressing through southwestern Oklahoma.  The storms are in a
   strongly sheared environment, with upscale growth being supported by
   ascent from and approaching mid-level wave near the NM/TX border. 
   Despite modest destabilization due to only mid/upper 50s F dewpoints
   across the warm sector, continued upscale growth of convection is
   possible, with the main threat being damaging wind gusts near the
   convective segments.  Low-level shear will also increase tonight as
   850mb flow increased to around 55 knots.  One or two strongly forced
   linear segments across downstream areas of southern Oklahoma and
   north/central Texas over the next several hours.  The probability of
   a downstream watch being needed is 60%.
