312 FXUS62 KFFC 091125 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 625 AM EST Tue Dec 9 2025 ...New 12Z Aviation Discussion... .KEY MESSAGES... Updated at 622 AM EST Tue Dec 9 2025 - Significant rainfall is not anticipated in the region through at least the middle of next week. - Mild temperatures, highs mainly in the 50s and lower 60s, will continue in the region through the end of the workweek. && .SHORT TERM... (Today through Wednesday) Issued at 212 AM EST Tue Dec 9 2025 Today through Wednesday: A weak wedge front sliding into the region this morning will produce low cloud cover and help limit high temperatures northeast Georgia this afternoon. Cloud cover should be the most widespread between 4 AM and 11 AM before boundary layer mixing takes hold and it mixes out this afternoon. Areas of western and northwest Georgia should see the most sunshine today, and consequently highs in the lower 50s are favored. Quiet weather and light winds will prevail tonight. This will open the door for radiational cooling, especially in central Georgia where high cloud cover should be more sparse. As a consequence overnight lows in the upper 20s and lower 30s are anticipate, with the coldest temps (outside of the mountains) expected in east central Georgia. Southerly winds ahead of a cold front will bring WAA to Georgia on Wednesday. Temperatures should respond by surging upwards (by about 10 degrees). Central Georgia should reach the lower 60s Wednesday afternoon, while widespread highs in the upper 50s can be expected in north Georgia. The stronger southerly flow should also produce wind gusts in the 20 to 25 mph range during the afternoon. && .LONG TERM... (Wednesday night through Monday) Issued at 212 AM EST Tue Dec 9 2025 On Wednesday night, shortwave troughing will be rotating through the Ohio Valley region towards the Northeast CONUS around the southern side of a closed mid-level low over Southeast Canada. As this occurs, it will serve to intensify an associated surface low moving from the Great Lakes towards Maine. A cold front extending from this low will meanwhile be pushing through north Georgia. With limited low level moisture, precipitation is looking increasingly unlikely ahead of this front, with PoPs of 15% or less being confined to the higher elevations of far northeast Georgia. Northwesterly flow at the surface and aloft will bring a reinforcing shot of cool and dry air into the forecast area. Low temperatures on THursday morning are expected to be in the upper 20s to low 30s to the north of I-85 and largely to the mid 30s to the south. High pressure building over the Southeast will promote benign weather conditions across the area on Thursday. Highs on Thursday will range from the upper 40s to low 50s in north Georgia (with low to mid 40s in the mountains) and mid to upper 50s in central Georgia. After Friday morning begins with lows in the low 30s across the majority of the forecast area, the center of the surface high will move east of Georgia during the daytime. Southwesterly low level flow on the back side of the high will allow for gradual moisture return, with dewpoints climbing from the 20s and low 30s to near 40 by Friday night. High temperatures will also be on the rise under the high and with warm advection from the Gulf, rising to the mid 50s to low 60s in north Georgia and mid 60s in central Georgia on Friday afternoon. Also on Friday, a quick-hitting disturbance will move southeastward through the jet, from the northern Great Plains towards the Ohio Valley region. Global model guidance indicates that increased mid-level moisture ahead of this feature could advance into north Georgia, but continues to disagree on the strength of the disturbance. Overall, forcing associated with this disturbance appears that it will be weak as far south as north Georgia, but a few isolated showers could be possible amid the increasing low level moisture if there is a sufficient mass response. With guidance continuing the trend towards drier solutions, PoPs associated with this system are limited to 10-15% in north and portions of west Georgia Friday night into Saturday. Both low and high temperatures on Saturday and Sunday have trended warmer than the previous forecast, with a slower progression of a cold front ahead of a building Arctic high surface high approaching from the northwest. Isolated to scattered showers, with PoPs of 20- 30%, are forecast in portions of north Georgia Saturday night into Sunday morning, with rain chances fizzling out by Sunday afternoon. Rainfall amounts are forecast to be about 0.10 inch in the far northern tier, with even less substantial totals to the south. There is the potential for significantly colder air to set up behind the front starting Sunday night into Monday, though the extent of how much temperatures drop will depend on the movement of the high`s center and the proximity of north/central Georgia to the core of the coldest air. Latest long range guidance is favoring a weakening of the surface high and a more northward track into the midwest, which would favor a less extreme temperature drop. Plenty of run to run inconsistency remains at this time, so the evolution and track of this Arctic high will need to be monitored. && .AVIATION... (12Z TAFS) Issued at 622 AM EST Tue Dec 9 2025 MVFR and patchy IFR ceilings (600 to 2500 ft AGL) will continue through 16Z today. Impacts are expected for the Atlanta area TAF sites, KMCN and KAHN. Ceilings should rapidly improve to VFR between 16Z and 20Z. Winds will remain light (6 kt or less), with a preference for south winds developing by 18Z today. //ATL Confidence...12Z Update... Moderate confidence in the ceiling heights and clearing times for today. High confidence in all other elements of the TAF. Albright && .PRELIMINARY POINT TEMPS/POPS...
