Areas affected...parts of eastern GA and SC

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.
