   The severe weather threat for Severe Thunderstorm Watch 172
   continues.

   SUMMARY...The ongoing supercell is expected to gradually weaken by
   04Z. Large to very large hail is still ongoing.

   DISCUSSION...The long-track supercell which has dropped very large
   hail across a long swath from near Childress to areas just west of
   the metroplex is still ongoing with golfball to baseball hail
   recently reported in Jack County. WoFS has been consistently
   weakening this storm considerably across Parker County for several
   runs. Given the extreme capping inversion seen on the 00Z FWD
   sounding, it seems unlikely this supercell will continue much
   longer. However, intense and long-lived supercells with strong
   internal pressure perturbations such as this have been known to
   persist well into a capped/stable airmass. Therefore, while the very
   large hail is expected to wane by the time the supercell enters
   Tarrant county, it is certainly possible it may last 1 or 2 counties
   farther east than anticipated which would impact at least portions
   of the the western metroplex. Therefore, Tarrant county has been
   added to severe watch 172.
