   Areas affected...portions of southeastern Oklahoma into northeastern
   Texas and far western Arkansas

   Concerning...Severe Thunderstorm Watch 70...

   Valid 020345Z - 020515Z

   The severe weather threat for Severe Thunderstorm Watch 70
   continues.

   SUMMARY...The severe threat continues across Severe Thunderstorm
   Watch 70. The main severe threat exists across northern portions of
   the watch as a line of storms approaches from the west. Damaging
   gusts are the main threat, though a tornado cannot be ruled out.

   DISCUSSION...The earlier QLCS with embedded supercells across
   northern TX has diminished in intensity given increasing inhibition.
   However, a pronounced QLCS is in progress across central OK, and
   this convection may move into Severe Thunderstorm Watch 70 over the
   next few hours with a damaging gust threat. Portions of the watch
   across eastern OK into western AR will most likely experience this
   QLCS later this evening. It is unclear how far south the QLCS will
   build into TX, so the severe threat is more conditional across the
   TX portion of the watch. Regional VADs, 03Z mesoanalysis, and RAP
   forecast soundings all show elongated hodographs with decent
   low-level curvature. However, CINH is increasing above the boundary
   layer given nocturnal cooling, tempering the tornado threat.
   Nonetheless, a tornado cannot be completely ruled out if a QLCS
   circulation can ingest any surface-based parcels.
