   Areas affected...Western North-Central TX

   Concerning...Severe Thunderstorm Watch 21...

   Valid 130803Z - 130900Z

   The severe weather threat for Severe Thunderstorm Watch 21
   continues.

   SUMMARY...Corridor of greater wind damage and QLCS tornado potential
   exists across western north-central TX.

   DISCUSSION...Recent KDYX imagery has shown a sharpening of the
   convective line moving into western north-central TX. This
   sharpening is coincident  with the lines interaction with slightly
   better low-level moisture and moderate southerly/southeasterly
   surface winds. Additionally, VAD wind profiles from KDYX show a
   well-defined rear-inflow jet. Interaction between this
   well-organized part of the convective line, southeasterly surface
   winds, slightly better low-level moisture, and favorable orientation
   of the storm motion to the vertical shear suggests a higher wind
   damage and QLCS tornado threat within this corridor for the next
   hour or so.
