   Concerning...Tornado Watch 723...

   Valid 291022Z - 291115Z

   The severe weather threat for Tornado Watch 723 continues.

   SUMMARY...Northern portion of extensive QLCS should continue to move
   more quickly east and out of WW 723 into parts of eastern Georgia
   and South Carolina by sunrise. Sporadic damaging winds along with a
   couple brief tornadoes should remain possible. A downstream tornado
   watch will likely be coordinated within the hour.

   DISCUSSION...The northern portion of the Deep South QLCS has more
   rapidly progressed eastward from 40-45 kts across central GA.
   Downstream air mass is characterized by scant MLCAPE below 250 J/kg,
   amid weak tropospheric lapse rates but 62-64 F surface dew points.
   Thermodynamics are unlikely to appreciably improve over the next 3-4
   hours. Still, the organized nature of the QLCS along with continued
   very strong low-level wind fields will support potential for a few
   transient mesovortices. A couple brief tornadoes and damaging gusts
   from 45-60 mph should remain possible through the mid to late
   morning.
