ATLANTA — Enjoy the outdoor window while it lasts. The National Weather Service is still selling a drier, more comfortable early week — with a clear midweek change signal.
The National Weather Service Peachtree City Area Forecast Discussion issued at 3:07 a.m. EDT Monday, Aug. 24, leads with three key messages:
- Mostly dry for North Georgia, with only low thunderstorm chances across parts of south-central Georgia through Tuesday.
- Shower and thunderstorm coverage increases by mid-to-late week as a front approaches.
- Seasonal temperatures are largely expected through the week.
At issuance, the product listed no watches, warnings, or advisories.
Short term: limited rain, lower humidity
The short-term section (issued 3:05 a.m. EDT) expects limited rain chances and fairly comfortable temperatures for North and Central Georgia through Tuesday.
A deep upper trough continues digging toward the Atlantic Coast, returning northwest flow aloft. At the surface, a frontal boundary draped across south-central Georgia is expected to sag slowly into North Florida. NWS says rain and storm chances stay limited and confined south of a Columbus-to-Swainsboro line, with those chances even lower Tuesday as the front settles into North Florida.
Most locations should stay dry through Tuesday under some mid- and high-level clouds. Daytime temperatures in the 90s (80s in the mountains) combined with relative humidity in the 30–40% range “will make it feel quite pleasant outside,” the discussion says.
Atlanta numbers in the AFD
Preliminary point guidance in the same discussion puts Atlanta near:
- Monday: high 92°F, low 69°F, rain chance about 0%
- Tuesday: high 93°F, low 71°F, rain chance about 0%
Other sample Monday highs: Athens 92, Macon 94, Columbus 94, Peachtree City 92, Blairsville 84, Vidalia 95. The higher Monday PoP in the table sits at Vidalia (30%), with Columbus near 10%.
Midweek: moisture and a cold front
The longer-range section (issued 3:05 a.m. EDT) says after the drier early week, moisture increases ahead of an approaching cold front by midweek. Dewpoints surge back toward the 70s by Wednesday into Thursday.
PoPs begin rising late Wednesday as a shortwave could bring thunderstorms from the west/northwest Wednesday evening into Wednesday night. The more substantial increase comes Thursday as the front moves in and lingers into late week. With precipitable water values surging back over 2 inches ahead of the front, locally heavy rainfall is flagged as a concern.
Morning lows stay largely in the 60s for much of north Georgia. Highs hold in the upper 80s to lower 90s, near seasonal normals.
Aviation note
The 06Z aviation section expected VFR at all sites, with isolated showers/storms staying south of Columbus/Macon Monday afternoon and no impacts expected at ATL. Confidence on the ATL package was listed as high.
How to use this
This is a forecast discussion, not a storm survey and not an air-quality product. Treat Monday–Tuesday as the dry, lower-humidity stretch for most of North Georgia; treat Wednesday night into Thursday–Friday as the next period when daily rain chances and heavier-rain risk climb again.
