Area Forecast Discussion
National Weather Service Peachtree City GA
346 PM EDT Sun Aug 7 2022

.SHORT TERM /Rest of today through Monday Night/...

Another day where a morning low level stratus deck could have
delayed destabilization and convective triggering across portions
of the area, though differential heating along the edges could
also focus development. Given how yesterday trended, will not
back down on the chance/likely pops and some may have to be raised
into the evening. Some strong and isolated severe intensity
possible like yesterday with strong/damaging winds, frequent
lightning and heavy rainfall.

Keeping potential for another low stratus deck and patchy fog
tomorrow morning, then again a very similar setup for
shower/storm development as we stay in the enhanced deep moisture
on the western side of the Bermuda high, which looks to dampen
some. Should still be in the high PWAT airmass (near 2") along
with decent SBCAPE of 2500+ J/kg. Expecting same general threats
of strong to damaging winds, frequent lightning and locally heavy
rainfall for some strong storms and a few possible severe.

Monday max temps could be a few degrees below climo given
aforementioned moisture/precip with highs mainly reaching the mid
80s to low 90s.

.LONG TERM /Tuesday through Sunday/...

No significant changes were made to the long term forecast.
Relatively weak flow and ample moisture through the atmospheric
column will be the rule Tuesday and Wednesday. As a result,
scattered to numerous diurnally-driven showers and storms are
expected both days. The GFS and ECMWF ensembles continue to depict
an upper-level pattern change Thursday into Friday as a ridge builds
across the western two-thirds of the country while a trough dips
across the East Coast states. This synoptic setup will translate to
a FROPA across the CWA Thursday into Friday, which warrants nearly
area-wide likely PoPs on Thursday. It appears that the front could
have the momentum/upper-level support to make it through the
majority of the CWA given the signal in the ensembles for a fairly
deep trough. Expect to see diurnally-driven showers and storms
Friday, Saturday, and Sunday with the bulk of convection focused in
the vicinity of the front (which will likely stall somewhere across
central Georgia). A few strong to severe storms will be possible
each day with damaging wind gusts, frequent lightning, hail, and
locally heavy rainfall all potential threats. Storms that are
particularly efficient rainfall producers and/or slow movers could
lead to flash flooding, especially in urbanized areas with
impervious surfaces and in areas that have increased top-soil
moisture from previous rainfall. Rainfall totals up to 0.50" are
forecast across much of the CWA through the long term period. Totals
of 1.00" to 1.25" are forecast across the higher elevations of north
Georgia where orographic uplift could enhance rainfall.

.AVIATION...
18Z Update...

Initial VFR conditions with mainly cu field 3500-4500 ft and some
showers and thunderstorms developing near some sites. Have tempo
groups for TSRA, 4SM and VRB gusts this afternoon that could be
extended into the evening. Another morning low stratus deck is
possible to bring IFR or lower cigs to the sites and some MVFR or
IFR VSBYs are possible too. Could have similar TSRA coverage again
Monday so have prob30 groups 18-00z. Initial winds have been
mainly light and VRB, then overnight look to be calm at most
sites. Winds then look to shift to SW for Monday by about 15z at
3-6 kts.

//ATL Confidence...18Z Update...

Low on wind direction this afternoon/evening.
Medium on TSRA coverage today and low cigs for Monday morning.
High on all else.
