SHORT TERM

(Today through Monday) Issued at 248 AM EDT Sun Aug 31 2025

Key Messages: - Isolated thunderstorms could be a hazard for outdoor activities across the NE Georgia mountains this afternoon.

Looks like the pseudo wedge of high pressure is beginning to build down the eastern seaboard and into NE GA this morning. This wedge is expected to continue to build SW into the state through Tue keeping the area under stable, cool, easterly flow. This will lead to mild and mostly dry weather across the area today. The exception to the dry conditions may be the northeast Georgia mountains. Weak convergent surface flow over NE GA combined with differential heating over the higher terrain could produce a favorable environment for afternoon convection. Moisture won't be overly impressive, but with convective temperatures in the 70s and surface dewpoints in the 60s this should be sufficient. Instability indices will be fairly weak due to the high pressure wedge building in so not expecting any storms that develop to become severe. The peak time window for any convection should be between 1 PM and 7 PM. Those participating in outdoor activities over the holiday weekend should monitor the lightning threat. Will still be dealing with a similar set up Monday but the wedge will have built in just a bit further so not so not seeing much in the way of convergent flow. With the continued easterly flow from the wedge we could still see some isolated precip chances across north GA but it will be more of an orographic effect.

The next wave to affect the state will move SE out of the northern plains Monday and push into NW GA Tue afternoon. This wave will bring increased precip chances to the area Wed/Thu.

LONG TERM

(Monday night through Saturday) Issued at 248 AM EDT Sun Aug 31 2025

Key Messages:

- Below normal temperatures continue through next week.

- Mainly isolated rain chances across the area except for Wed/Thu as a system moves through the region.

Discussion:

The extended begins with the wedge from the short term still dominating the weather pattern over north and central GA. There is a short wave developing over the northern plains Mon and it slowly moves SE, pushing into NW GA Tue afternoon/evening. This wave settles in over the state Wed bringing increased precip chances (40% to 60% PoPs) but the wedge will still be in place so not expecting much in the way of any severe storms. This wave moves NE Thu morning as the next frontal boundary moving SE out of the northern plains pushes into NW GA Thu afternoon/evening. This frontal boundary is not expected to have a lot of moisture associated with it, but it will usher in a much drier and cooler airmass Friday and into next weekend.

Temps will remain below seasonal norms with highs mainly in the upper 70s to middle 80s. Night time low temps will drop down into the upper 50s to middle 60s through day 7.

AVIATION

(12Z TAFS) Issued at 720 AM EDT Sun Aug 31 2025

Primarily VFR conditions across the region through the TAF period after some brief MVFR CIGs/VIS through 14Z this morning around the ATL sites and MCN. Any isolated SHRA/TSRA this afternoon should remain across far northern GA. Light winds turn out of the east around 5-9kts during the day, becoming light again this evening.

//ATL Confidence...12Z Update... High confidence in all elements.
