Area Forecast Discussion
National Weather Service Peachtree City GA
1201 PM EDT Wed Sep 8 2021

.UPDATE...
Morning fog has lifted leaving behind mostly cloudy skies. The
previous assessments for the short term forecast period remains on
track, and no changes were made late this morning. Heavy rainfall
and isolated thunderstorms are still anticipated as a strong fetch
off the Gulf aids in increasing PWs ahead of a cold front progged to
move through the FA this evening. Localized flooding will be possible
especially across areas that are already or continue to be saturated
from last nights heavy rainfall.

&&

.PREV DISCUSSION... /Issued 740 AM EDT Wed Sep 8 2021/

SHORT TERM /Today through Thursday/...
GA will remain on the southern end of an upper trough north of the
Great Lakes. A nearly stationary boundary lingered across north GA
this morning. Residual instability on this boundary could trigger
convection at any time and isolated thunderstorms continued to pop
up this morning. The best time for showers/thunderstorms should be
late morning into the late evening as waves travel along the
boundary. Models indicate another push of deep tropical moisture
from the Gulf today as a weak low pushes from the FL panhandle
across southern GA tonight into Thursday. The deepening Canadian
trough will push another front into GA late tonight and Thursday
with some drying across north GA. Remnants of the surface boundary
combined with weak waves will keep highest pops over central GA on
Thursday. Heavy rain and possible flooding issues could occur with
some of the slower moving storms.

41

LONG TERM /Thursday Night through Tuesday/...
The extended forecast begins with the second drier frontal
boundary that moved into the area in the short term has pushed SE
into South GA. This front will have ushered in a much drier
airmass across north and central GA which will keep most of the
area dry through the weekend. There is expected to be a little bit
of moisture return across south GA Sat/Sun but the deep layer moisture
stays across the northern gulf and northern FL. With its proximity
to central GA could not completely pull PoPs out of the forecast
to keeping just a slight chance of precip in every afternoon
through Tuesday.
