Areas affected...Southeast GA...Far Northeast FL

Concerning...Severe potential...Watch unlikely

Valid 211945Z - 212145Z

Probability of Watch Issuance...20 percent

SUMMARY...Ongoing convective line may produce isolated damaging
gusts from 45 to 60 mph as it continue eastward across southeast
Georgia and far northeast Florida.

DISCUSSION...Recent regional radar imagery has shown an increase in
intensity of the convective line that extends from extreme southern
SC southwestward across southeast GA, just ahead of a
southeastward-progressing cold front. Modest buoyancy exists
downstream of this line, supported by surface temperatures in the
upper 70s and dewpoints in the mid 60s. Additionally, a shortwave
trough is moving quickly across the Southeast, contributing to
increasing large-scale ascent and deep-layer vertical shear across
the region. These factors are expected to result in maintenance, or
perhaps even some modest strengthening, of the ongoing line as it
moves eastward. Primary threat from this line is isolated damaging
gusts from 45 to 60 mph. Limited spatial extent and intensity of
this threat is expected to preclude the need for a watch.
