   Areas affected...North Central TX

   Concerning...Tornado Watch 171...

   Valid 290002Z - 290200Z

   The severe weather threat for Tornado Watch 171 continues.

   SUMMARY...An intense supercell producing very large hail and
   damaging winds will continue southeastward.  Other isolated cells
   may affect areas to west near Eastland and Stephenville.

   DISCUSSION...An intense supercell with a long history of very large
   and damaging hail is currently located in Johnson county TX.  This
   cell will continue to track southeastward for the next 1-2 hours
   into a very moist and unstable air mass.  Shear profiles are
   sufficient for all severe modes, including wind-driven significant
   hail and occasional tornadoes.

   New storms have formed on the western flank of the large supercell,
   over Stephens and Palo Pinto counties.  These storms appear to be
   behind the primary outflow of the supercell, but sufficient elevated
   CAPE will pose a risk of large hail from this activity as it sags
   southeastward.
