Area Forecast Discussion
National Weather Service Peachtree City GA
303 PM EDT Sat Aug 14 2021

.SHORT TERM /Today through Monday/...
Current 500mb analysis shows a weakness in the ridge across the Gulf
Coast States. A flat trough is situated across the Great Lakes and
Mid Mississippi River Valley. The western ridge will retrograde a
bit tomorrow with the trough over the Middle Mississippi River
Valley digging south towards the Gulf States. Water vapor loop shows
tropical moisture being funneled from the remnants of Fred across
the FL peninsula and the GA coast. This axis should begin to shift
westward on Sunday. At the surface, high pressure will continue
across the CWA through the period as the western Atlantic ridge
tries to build westward. The remnants of Fred are forecast to remain
offshore through the short term period of the forecast.

Mostly diurnal convection expected this evening. With the tropical
moisture increasing, will leave in a slight chance for the overnight
period. Pops should become more widespread on Sunday as the axis of
tropical moisture shifts westward.

Lapse rates this afternoon are moderately steep across east central
portions of GA. Already had some isolated reports of small hail
within the thunderstorms and expect this trend to continue.
Widespread severe weather is not expected, but a few severe
thunderstorms are possible. Expect damaging wind gusts to be the
primary severe weather mode with some potential for large hail with
the current lapse rates. BL winds remain fairly light through the
period, so slower moving storms are likely...leading to locally
heavy rainfall.

.LONG TERM /Monday Night through Friday/...
The first part of the long term will be dominated by what is now the
remnants of Tropical Depression Fred currently located over Cuba. As
Fred emerges back into the Gulf of Mexico the NHC has indicated that
it will likely regain it's status as a tropical storm before making
landfall in the gulf. The effects of Fred will likely be seen late
Monday and into Tuesday along the Georgia/Alabama border. The main
concern will be heavy rain, especially after Fred is absorbed into a
stalled frontal boundary across north Georgia Tuesday and Wednesday.

The stalled from finally gets pushed out by Friday but from there
the forecast will be dependent on Tropical Storm Grace which is
following a similar path to Fred. The models are in major
disagreement on what track Grace will eventually take. The GFS and
Canadian models both bring Grace into the Gulf where it undergoes
further strengthening. the ECMWF however keeps the storm off the
coast of the Atlantic which allows for a sinking front to bring
another round of showers and thunderstorms to the area next weekend.

Temperatures during this time period will likely run below normal
given the rain we are expecting. Highs will likely be moderated to
the low 80s and upper 70s and overnight lows in the upper 60s and
lower 70s. Flooding will be possible this week, but given ongoing
uncertainty in the track of both tropical systems, nailing down the
areas of highest QPF has been difficult.

.AVIATION... 18Z Update... Convection should last into the early
evening. Some sct MVFR is possible towards 12Z SUN. Winds will be
a challenge, do think convection will still be lingering between
22Z-02Z and wind direction will likely be VRB at this time.
However, winds should go back over to the east side and stay
overnight. More widespread coverage of precip is expected
tomorrow.

//ATL Confidence...18Z Update...
Low-Med confidence on wind direction between 22Z-02z. Otherwise,
Med-Hi confidence remaining elements.

This Hazardous Weather Outlook is for portions of North and Central Georgia.

.DAY ONE...This Afternoon and Tonight...

Scattered thunderstorms are expected this afternoon and evening
across north and central Georgia. A few storms may become strong
to severe, capable of producing isolated damaging wind gusts,
frequent lightning, and locally heavy rainfall.

.DAYS TWO THROUGH SEVEN...Sunday through Friday...

Scattered to numerous thunderstorms will be possible each day
Sunday through Friday, with the highest chances during the
afternoons and evenings. The primary hazards with any thunderstorm
will be heavy rain, gusty winds, and lightning. Although
widespread severe weather is not expected at this time, an
isolated severe storm cannot be ruled out each day, with damaging
winds as the main threat.

Although much uncertainty still remains, it is likely that a
tropical low will impact the Southeast, including portions of
central and north Georgia, early this week. Please continue to
monitor the forecast for further developments.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed through tonight.
