.SHORT TERM...
(This afternoon through Saturday)
Issued at 231 PM EDT Fri Aug 22 2025

Key Messages:

  - Flood Watch across portions of east and east central Georgia.
    Areas within the watch could see 4+" of rainfall Today and
    Saturday from slow moving thunderstorms. Flood Watch is in
    effect until 2am Sunday.

Forecast:

Scattered showers and thunderstorms across the region but
expecting more coverage as we go into the evening hours. The
frontal boundary that pushed into N GA yesterday is moving very
slowly south. It almost appears to have stalled across the ATL/AHN
areas and is acting as a focal point for the developing storms.
Easterly flow along with a surface ridge/pseudo wedge building
into NE GA will pull in additional moisture from the Atlantic,
which keeps forecast PWAT values 2" or higher across much of the
CWA Today and Sat. This is a very weak wedge with light surface
winds so any storms that develop will be relatively stationary,
which further increases the potential localized rain totals and
some possible flooding. Most areas should see 1" to 3" totals with
some isolated 4" to 5" totals through Sat night. Flash Flood
Guidance across the area is typically pretty high thanks to soil
type, especially in the summer where ground and plant uptake of
water is very high, but relatively heavy rains over the past few
days have preconditioned soils in some locations, and the rainfall
rates could easily overwhelm some areas (especially more urban
areas). Have continued with the current Flood Watch across
portions of east and east central GA with all this in mind.

With the cloud cover and expected rain temps will be mainly in
the 80s across the CWA with some 70s in the NE GA mountains. Low
temps tonight and Sat night will be in the 60s and 70s.

.LONG TERM...
(Sunday morning through next Thursday)
Issued at 231 PM EDT Fri Aug 22 2025

Key Messages:

- Cooler and drier as we start next week.

- Little to no thunderstorm activity expected.

The long term picks up just ahead of a cold front that will sweep
the remains of the stationary front out of our CWA and establish
a taste of fall for most of the forecast area. Temps will run
below average for late August with highs in the low to mid 80s and
overnight lows in the 60s. The front will have the added bonus of
flooding the area with dry air, and our minimum RH values will
fall into the 40s nearly every day. Overall we`re expecting
extremely nice conditions through the long term.

High pressure and dry air will keep thunderstorm chances limited
to nearly zero all week. A few of the models are signaling at
least a chance for some showers and thunderstorms to return to the
CWA by next weekend, but even those chances are on the marginal
side given how far out in the future we`re talking.

.AVIATION...
(00Z TAFS)
Issued at 723 PM EDT Fri Aug 22 2025

Scattered convection is pushing across the state from east to
west this evening. Expecting that the most likely time frame for
TSRA at the TAF sites will be 00z-02z, although VCSH/SHRA will be
possible outside of that time frame. CIGs will drop overnight,
with widespread IFR expected. LIFR CIGs (and reduced VIS) will be
possible, especially where rain occurs this evening. Similar to
today, CIGs may be slow to improve tomorrow (Saturday) with MVFR
well into the afternoon. Winds will remain out of the east at 5-10
kts through the TAF period (with some sites going light/VRB to
calm overnight).

//ATL Confidence...00Z Update...
Medium confidence on LIFR potential.
High confidence on all other elements.
