   Areas affected...Parts of the eastern OK/TX Panhandles into far
   northwest OK

   Concerning...Tornado Watch 429...

   Valid 172305Z - 180000Z

   The severe weather threat for Tornado Watch 429 continues.

   SUMMARY...Intensification of an ongoing discrete supercell is
   possible as it continues southeastward over the next couple hours --
   with an associated risk of supercell tornadoes.

   DISCUSSION...A discrete supercell has developed over the OK
   Panhandle, within a localized zone of surface convergence. Strongly
   unstable inflow for this storm and large streamwise vorticity
   (250-300 m2/s2 effective SRH) will support the intensification of
   this storm as it tracks southeastward over the next couple hours. If
   this occurs, supercell tornadoes and large hail will both be
   concerns.
