237 FXUS62 KFFC 131042 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 642 AM EDT Sun Sep 13 2026 ...New 12Z Aviation Discussion... .KEY MESSAGES... - Hot and dry conditions are expected for most on Sunday. - Patchy dense fog is possible this morning in areas that received recent heavy rainfall in recent days. - Surface high pressure will suppress meaningful rain chances through Friday (15% or less each afternoon). && .SHORT TERM... (Today through Monday) Issued at 318 AM EDT Sun Sep 13 2026 Patchy dense fog has developed across portions of northeast Georgia this morning, and further development is possible, especially in areas that received heavy rainfall yesterday. As mid-level ridging moves in aloft on Sunday, meaningful precipitation chances will be effaced by strengthening subsidence, reinforced by building high pressure at the surface. Isolated thunderstorms are possible across our far southern tier, in the vicinity of a lingering tendril of increased moisture, but most will see a dry (if hot) end to the weekend. The start of the work week will see a backdoor cold front approach north Georgia, with surface winds shifting solidly to the northeast as it does so. An isolated shower or thunderstorm is possible across the terrain of northeast Georgia, otherwise expecting minimal sensible impacts from its arrival -- temperatures are actually likely to climb a couple of degrees, topping out more solidly in the 90s areawide. && .LONG TERM... (Monday night through Saturday) Issued at 318 AM EDT Sun Sep 13 2026 The long term period will begin on Monday night with an upper ridge extending from the Deep South into southeast Canada. A surface high associated with this ridge will also be moving from the eastern Great Lakes towards the Northeast. Though low level moisture from the Gulf will linger across Georgia (with dewpoints in the upper 60s to low 70s), subsidence of dry mid-level air under the ridge will largely suppress convection on Tuesday afternoon, with only isolated thunderstorms anticipated in portions of east-central Georgia. Underneath mostly clear skies, high temperatures are forecast to rise into the low 90s in all but the far northeastern mountains on Tuesday afternoon. Late Tuesday into Wednesday, the surface high will lead to the development of a CAD wedge along the lee side of the Appalachian, which is expected to spread relatively cooler and drier air into the eastern portions of Georgia. Low temperatures on Wednesday and Thursday will start each morning in the 60s while high temperatures in the afternoons will be largely in the upper 80s. With the upper ridge lingering over the eastern CONUS, rain chances will remain minimal across the forecast area on Wednesday and Thursday. Chances for diurnally-driven showers and thunderstorms will gradually increase starting on Friday and into next weekend as the axis of the ridge begins to retrograde back to the west of the area. && .AVIATION...
