Area Forecast Discussion
National Weather Service Peachtree City GA
130 PM EDT Sat Aug 8 2020

.PREV DISCUSSION... /Issued 1039 AM EDT Sat Aug 8 2020/

UPDATE...
Weak boundary remains across central GA this afternoon. Typical
isolated to scattered convection expected today. Have made some
tweaks to the temps, but otherwise, no major changes anticipated.

PREV DISCUSSION... /Issued 740 AM EDT Sat Aug 8 2020/

SHORT TERM /Today through Sunday/...
An upper ridge will build across the southeast through the short
term. The remnants of a surface boundary persists across central GA
while somewhat drier air has spread into portions of north GA. An
unstable air mass and diurnal heating will support isolated to
scattered convection this afternoon into the evening...mainly across
central GA. Not much change expected for Sunday. Slight chance to
chance pops for the afternoon with diurnal heating. Heat Index
values are forecast to remain below advisory criteria today and
Sunday...ranging from 100 to 103 mainly across central GA.

41

LONG TERM /Sunday Night through Friday/...
A somewhat typical summertime pattern looks to be in store for
the long term highly characterized by weak flow aloft and weak
surface high pressure. The nature of the upper flow will allow
for weak short waves to move across the area. This will enhance
shower and thunderstorm chances along with daytime instability.
The shower and thunderstorm chances will favor the afternoon and
evening but not necessarily end at night. Model guidance is
increasing the overall moisture and this will lead to higher rain
chances during the week, especially Wednesday through Friday.

Aiding the shower and thunderstorm chances will be high temperatures
in the 90s for much of the area away from the mountains. This
will allow the heat index to get into the 100 to 105 range for
central and portions of N GA well into the week.

.AVIATION...
18Z Update...
Winds will remain the forecast problem. Speeds are very light and
are typically averaging 3-4kt. Models do seem to want to favor the
west side today, so at ATL have indicated a direction. Elsewhere,
winds may be more VRB. Wind speeds again tomorrow will be 3-4kt
and even more variable in nature. Pops pretty low the next two
days...so have only included a VC.

//ATL Confidence...18Z Update...
Med confidence winds through the period. High confidence remaining
elements.
