   Concerning...Tornado Watch 135...

   Valid 230001Z - 230130Z

   The severe weather threat for Tornado Watch 135 continues.

   SUMMARY...The environment remains supportive of all severe hazards,
   including a strong tornado, downstream of the ongoing storm across
   Jasper County TX.

   DISCUSSION...Long-track supercell moving into Jasper County TX has
   had a history of producing strong low-level rotation. Recent
   signatures suggest the storms has undergone recycling of the
   mesocyclone as it continues to move within a very favorable
   environment. KPOE VAD recently sampled 0-1 km SRH over 450 m2/s2 and
   70 kt of 0-6 km bulk shear. Temperatures ahead of the cell are in
   the mid 70s with dewpoints in the low 70s. Mesoanalysis estimates
   MLCAPE around 2000 J/kg. The strong buoyancy expected to persist
   while the low-level jet gradually increases. The ongoing storm
   continues to move unimpeded with the warm sector. In all, the
   environment remains very favorable for storm persistence with a
   continued threat for all severe hazards, including a strong tornado.
