Area Forecast Discussion
National Weather Service Peachtree City GA
334 PM EDT Fri Aug 27 2021

.SHORT TERM /Tonight through Saturday Night/...

Upper ridge building into the region remains centered over the
Carolinas through the period. This keeps a north/south gradient for
PoPs in place with isolated diurnal convection across the north and
scattered diurnal convection across the south, aided by weak mid/
upper-level energy riding westward across south Georgia around the
southern periphery of the ridge. Temperatures remain seasonably
warm.

.LONG TERM /Sunday through Friday/...

No big changes for the long term as a ridge of high pressure covers
the southeast. Hurricane Ida is forecast to enter the central Gulf
this weekend...weakening and moving up the lower MS Valley Monday
and Tuesday. Remnants expected to move into the vicinity of northern
AL by mid week.  Not sure how much tropical moisture our area will
see this weekend...but looks like the potential is there for some
increase in pops mainly for Tuesday into Wednesday. Have continued
with likely across the north and west for Tuesday and over the far
north for Wednesday...otherwise mainly a summer pattern. The
previous discussion is included below.

Previous...

Due to the center of the Bermuda high retrograding further west over
the Carolinas early this weekend, the extended opens with a pocket
of comparatively drier air (PWATs of 1.2-1.5") edging over the CWA.
As a result, PoPs range from slight to low end chance for much of
our area through Sunday. Moving into the week, the Bermuda high
further degrades, leaving behind weak ridging and seasonable rain
chances.

The forecast from Tuesday on is highly dependent on changes to the
forecast track of Tropical Storm Ida. As of this update, the latest
NHC track has landfall occurring in SE LA, followed by movement to
the northeast once over land. At the very least, this track places a
broad swath of tropical moisture over our area, likely to be
accompanied by widespread showers and storms and periods of heavy
rainfall. The orientation of the storm as it moves off to our north
and west on Wednesday (placing us in the right front quadrant)
suggests there may be a severe concern, but this is again contingent
on how quickly Ida weakens over land and the finalized track and
intensity forecast. For now, have left PoPs at high end chance to
likely as we await further guidance.

.AVIATION...
18Z Update...

VFR conditions prevail across the forecast area through 06Z, outside
of isolated to scattered convection. Areas of MVFR or lower ceilings
and visibilities develop between 06Z and 10Z, with good chances for
impacts, to some degree, at all TAF sites. Conditions begin
improving after 12Z, with most areas back to VFR by 14-16Z. Winds
remain easterly, generally 5-10kt during the day and 5kt or less
overnight.
