Area Forecast Discussion
National Weather Service Peachtree City GA
204 PM EDT Tue Aug 12 2025

...Afternoon Area Forecast Discussion...

.SHORT TERM...
(This afternoon through Wednesday)
Issued at 141 PM EDT Tue Aug 12 2025

Key Messages:

    - Scattered to numerous showers and thunderstorms can be expected
      today and again on Thursday.

    - Areas of heavy rainfall could lead to localized flash
      flooding concerns, especially in north Georgia this evening.

Weak surface low analyzed off the mouth of the MS River with
northward extending weak trof axis across AL into NW GA...much
like a tropical wave. Moisture pooling along the boundary with
PWATs of 2.0 to 2.2 inches extending north from the Mobile AL
region northeastward into NW GA...and 2-2.1" PWATs elsewhere
across the CWA. Enough surface heating has occurred to allow
surface instabilities to surge to 3000-4000 j/kg across the area
as well which will serve to aid in more widespread shower and
tstorm activity to occur later today/this evening. Given the high
PWAT values in conjunction with a weak convergent axis and
orographic lift, expect heavier rainfall potential across northern
GA this evening as storms develop and lift north across the area.
WPC does highlight a slight risk ERO across north GA today and CAM
guidance, while splotchy, does hint at some isolated higher totals
up to 3 or 4 inches possible in localized spots.

Weak trof axis remains generally in place tomorrow so expect a
similar type setup with afternoon showers and storms developing
within the higher PWAT atmosphere in place. With no real mid level
or jet support, expect activity to be largely driven by surface
heating or aggressive gulf coast sea breeze. CAM guidance is
suggesting upwards of 4000 j/kg CAPE to setup across the area
before storms develop and tap the energy.

.LONG TERM...
(Thursday morning through next Monday)
Issued at 141 PM EDT Tue Aug 12 2025

Key Messages:

    - Daily afternoon/evening thunderstorm chances through the
      weekend.

    - Temps returning to seasonal norms by late week.

Discussion:

The extended forecast continues with afternoon and evening showers
and thunderstorms expected each day. Temps also climb back to near
seasonal norms by Thu/Fri with highs back to near 90 north, to the
mid 90s across central GA. By Thu, the upper level ridge from the
short term continues to strengthen and becomes centered over central
FL and the eastern Gulf. This upper level ridge will keep deep moist
southwesterly flow over GA with small vort maxes pushing into the
area. This flow becomes a bit more westerly by Fri keeping moist
flow over the area through the weekend. With day time heating and
temps expected to get back up to seasonal norms we will continue to
see afternoon and evening showers and thunderstorms through day 7.
This strong upper level ridge becomes centered over the northern
Gulf by Fri/Sat then it moves over the western gulf by the beginning
of next week. This will help to keep any storms that develop capped
from becoming too strong or severe.

.AVIATION...
(18Z TAFS)
Issued at 130 PM EDT Tue Aug 12 2025

Afternoon showers and isolated TS starting to develop which
should become more numerous through the afternoon. Included Tempo
at all sites based on latest guidance which is centered late
afternoon into early evening with storm risk. The main culprit, a
weak tropical wave, passes through the region overnight which
will trigger a wind shift to the SW between 08-10z. Additionally,
given the low level moisture around and high RH, expect some low
IFR cigs to develop around metro sites toward dawn on Wednesday.
Afternoon showers and storms return on Wed at area taf
sites...included a prob30 for ATL.

//ATL Confidence...18Z Update...
MEDIUM CONFIDENCE ON STORM TIMING AND IFR CIGS WED AM
HIGH CONFIDENCE ALL OTHER ELEMENTS.
