102 FXUS62 KFFC 070610 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 110 AM EST Sun Dec 7 2025 ...New 06Z Aviation Discussion... .KEY MESSAGES... Updated at 1254 AM EST Sun Dec 7 2025 - Dense fog will create hazardous travel conditions in north and central Georgia through 10 AM today. - Light rainfall returns to the region Sunday night and Monday morning with amounts in the 0.01 to 0.35 inch range expected. - An additional round of modest rainfall is anticipated in the region Thursday into Friday. && .SHORT TERM... (This afternoon through Sunday) Issued at 122 PM EST Sat Dec 6 2025 Current radar imagery shows showers moving more into central GA and should be on their way out of the area by later this afternoon. Moist conditions are expected to hold into the overnight hours with limited dry air movement. Another shortwave moves across the southeast tomorrow surging moisture out ahead in north and central Georgia tonight into tomorrow morning. Near surface light easterly flow, increasing moisture, and some CAA will drive the potential for widespread fog for areas mostly along and south of I20. Visibilities may drop to 1/4 mile or less in some areas and a dense fog advisory may be necessary for central and portions of north Georgia. More patchy fog is also possible in northern GA and may be co-located with temperatures near freezing. Surfaces will likely not be cold enough for any rime icing though there is some potential on the protected slopes in far north Georgia. Low clouds and will likely hold conditions steady late into the morning tomorrow (10/11am). Showers return to the area once again tomorrow evening. No thunderstorms area expected at this time. && .LONG TERM... (Monday morning through next Friday) Issued at 122 PM EST Sat Dec 6 2025 The mid-/upper-level shortwave trough axis will shift east of the County Warning Area (CWA) on Monday, in turn pushing what remains of the Gulf moisture feed eastward as well. The result will be rain showers -- likely relegated to the eastern half or so of the CWA -- tapering off over the course of the day. The National Blend of Models (NBM) added light snow mixing with rain in the north Georgia mountains on Monday, but I opted to omit any frozen precip as I suspect that the atmospheric profile will be too dry in the mid-/upper-levels and too warm at/near the surface. Tuesday and Wednesday will bring dry, mostly sunny conditions thanks to high pressure and a continental airmass. Wednesday should be a noticeably warmer day than Tuesday, with highs in the mid-50s to lower 60s compared to upper 40s to mid-50s. This warm- up will occur in response to low-/mid-level flow shifting from northerly to westerly in advance of a northern stream shortwave/jet streak that will dive southward and eastward across the Ohio/Tennessee River Valleys Wednesday into Thursday. Like the previous long term discussion mentioned, ensemble guidance continues to differ regarding the southern extent of the associated surface low and front, as well as how much moisture will be in place. Have capped PoPs at 30% (analogous to widely scattered showers) Wednesday night through Friday morning given said forecast uncertainty. As the forecast stands now, the end of the long term period could bring quite the cool-down, with Saturday (12/13) morning lows in the mid-20s to lower 30s across much of the CWA. Stay tuned! && .AVIATION... (06Z TAFS) Issued at 1254 AM EST Sun Dec 7 2025 Widespread dense fog (visibilities below 1/4 mile) will remain the primary aviation hazard through 15Z Sunday. Impacts will occur at the TAF sites for a prolonged period. Visibility and ceilings will improve after 15Z, but a mix of IFR and MVFR ceilings (300 to 2000 ft AGL) will likely linger through the day on Sunday. Light (2 to 6 kt) easterly winds (060 to 120 degrees) will occur through the day on Sunday. Light rainfall will return between 00Z and 18Z Monday. //ATL Confidence...06Z Update... High confidence in multiple hours of dense fog through 15Z Sunday. High confidence in the wind speeds and direction through Sunday. Moderate confidence that ceiling will rise to MVFR by 18Z Sunday.
