   Areas affected...Southern/eastern GA and adjacent parts of the FL
   Panhandle and western SC

   Concerning...Tornado Watch 354...

   Valid 190116Z - 190315Z

   The severe weather threat for Tornado Watch 354 continues.

   SUMMARY...Some threat for damaging winds and brief tornadoes may
   continue into the late evening.

   DISCUSSION...A QLCS with embedded circulations is moving eastward
   across central GA as of 0115 UTC. The KJGX VWP continues to depict
   seasonably strong low/midlevel flow, with favorable low-level
   veering and 0-1 km SRH near/above 150 m2/s2. Downstream wind
   profiles are expected to remain favorable through the evening,
   though earlier convection has resulted in some cooling and
   stabilization from east-central GA into parts of SC. Some low-level
   moisture recovery is possible in advance of this QLCS, which may
   help to sustain this system and result in a continued threat of wind
   damage and brief tornadoes into the late evening, though the weaker
   buoyancy with eastward extent results in uncertainty regarding
   magnitude of the nocturnal threat in this area. The need for a
   downstream watch is uncertain, and will depend in short-term
   observations regarding storm organization and any buoyancy recovery.

   Farther southwest, occasional semi-discrete cells have been noted
   between Dothan and Tallahassee. Any persistent small supercells
   could continue to pose a brief tornado threat, given the presence of
   very rich low-level moisture and favorable low-level shear/SRH.  

   To the west of Dothan, persistent convection has recently surged
   eastward, with rather strong winds noted at 1 km AGL from KEOX. This
   convection is largely north of the outflow from earlier convection,
   resulting in certainty regarding severe-wind potential at the
   surface, but at least localized wind damage will be possible as this
   small cluster moves across southeast AL.
