Areas affected...southwest GA

Concerning...Tornado Watch 285...

Valid 191813Z - 191915Z

The severe weather threat for Tornado Watch 285 continues.

SUMMARY...Several supercells are developing in the warm sector
across southwest GA.  The risk for a couple of tornadoes is
increasing with potential perhaps peaking between now (210pm EDT)
and 4pm EDT.

DISCUSSION...Radar/satellite imagery indicates the development of
several supercells in a destabilizing warm sector near the southeast
AL/southwest GA border early this afternoon.  KEOX VAD data
indicates around 200 m2/s2 0-1km SRH per observed storm motions.  A
maritime warm front is draped across southwest GA with mid 80s deg F
temperatures and southerly flow located to its south, whereas upper
70s and backed east-southeasterly surface flow is located to the
north of the boundary.  As storms interact with the vorticity-rich
zone along the maritime warm front, it seems tornado potential with
the supercells will be greatest in the vicinity of the boundary. 
Additional storms are developing to the south of a storm with a
history of a tornado, and these storms will likely move north into
the warm frontal zone and potentially pose a tornado risk.
