   Areas affected...east Texas

   Concerning...Severe potential...Tornado Watch likely 

   Valid 110249Z - 110445Z

   Probability of Watch Issuance...95 percent

   SUMMARY...A tornado watch downstream of WW0004 will be needed across
   portions of east Texas in the next hour. Tornadoes and damaging
   winds will be the main severe threats.

   DISCUSSION...A line of thunderstorms with a couple of embedded
   supercells is stretching south-north across central Texas. This line
   of storms is expected to continue and further mature into a squall
   line with plenty of instability and shear downstream. Additionally,
   the low-level jet, which is already 40-50+ knots per mesoanalysis
   and observed 00z soundings, will strengthen overnight. While the
   flow will be mostly parallel to the line, the strong flow/forcing
   will still result in a squall line moving eastward with cell motion
   moving more to the northeast. Damaging wind gusts and QLCS tornadoes
   are the main severe threat. A couple of discrete cells may form
   ahead of this line, which would increase the tornado threat.
