   Concerning...Severe Thunderstorm Watch 403...

   Valid 100120Z - 100245Z

   The severe weather threat for Severe Thunderstorm Watch 403
   continues.

   SUMMARY...Upscale growth into an MCS is underway, with severe gusts
   becoming the main threat, though an instance of severe hail is
   possible. The severe threat may expand into far western TX, where a
   downstream Severe Thunderstorm Watch issuance will probably be
   needed.

   DISCUSSION...Supercells and multicells have been growing upscale
   into an MCS based on recent MRMS mosaic radar imagery. KFDX radar
   data also shows coherent, bowing inbound velocities exceeding 50 kts
   under 500 m above ground level, suggesting that potentially severe
   gusts may become the predominant hazard over the next few hours.
   Large hail could still occur with the deeper storm cores. With
   continued upscale growth, MCS propagation should take a more
   rightward turn to the southeast, into western TX, along an 850 mb
   thermal gradient, where low-level moisture is also maximized. As
   such, a downstream issuance of a Severe Thunderstorm Watch will
   probably be needed in the next hour or two.
