   Concerning...Tornado Watch 135...

   The severe weather threat for Tornado Watch 135 continues.

   SUMMARY...New storm development across east-central TX may
   strengthen into supercells capable of all severe hazards.

   DISCUSSION...Surface convergence has resulted in additional
   development across east TX. This area is well ahead of the dryline
   moving through north-central TX and south of the warm front
   extending through north-central LA southwestward into southeast LA.
   The air mass ahead of this new development (i.e. from east-central
   TX into west-central LA) is unstable, suggesting the potential for
   storm intensification and maturation. Surface winds are a bit weaker
   and more veered than areas farther east but low/mid-level winds
   remain strong, leading to large low-level hodographs and strong
   deep-layer shear. As such, there is some potential for additional
   storm maturation into supercells capable of all severe hazards. Main
   uncertainty regarding storm maturation is the effect of ongoing
   nocturnal stabilization.
