####018005028#### FXUS62 KFFC 071847 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 147 PM EST Sun Dec 7 2025 ...Afternoon Area Forecast Discussion... .KEY MESSAGES... Updated at 127 PM EST Sun Dec 7 2025 - Patchy dense fog remains possible across portions of north and central Georgia, especially along the I-20 corridor, until around 3 PM today. - Light rain is expected across the area tonight into Monday morning, with rain chances returning Thursday into Friday. Modest rainfall totals of less than 0.4 inch are expected. && .SHORT TERM... (This afternoon through Monday) Issued at 127 PM EST Sun Dec 7 2025 Fog continues to hold across much of the metro area with patches of dense fog also further south and in the northwest. Satellite shows dense low cloud cover across much of the area and in valleys of north Georgia. High cirrus, which moved in this morning, have acted as a blanket to keep the sun from burning off much of the fog and cloud cover. This required both an extension of the dense fog advisory earlier as well as the issuance of a special weather statement for patchy dense fog with vsby <1SM. Moisture will continue to stream into the area from the southwest aloft ahead of the next quick shortwave overnight tonight. A line of showers will move through the area tonight bringing light accumulations of generally <0.4" for much of the CWA. Cloud ceilings will remain low, holding dreary conditions well into tomorrow morning and early afternoon. Dry air moving in behind the system will help to clear out some clouds as we go into Monday night and Tuesday morning, though this is short lived. Winds out of the north will quickly transition back to near surface east flow, redeveloping the wedge and bringing a return to dreary cloudy conditions. Light wrap around moisture into the wedge in the far northeast mountains of the CWA may bring some light precipitation Monday night, however PoPs remain at a meager 15-20% for the small area. Should anything fall, temperatures may be close to freezing bringing a light wintry mix. No accumulations are expected and impacts, should anything even fall, will be limited to none. In all likelihood, precipitation may only be likely in a warmer solution which would not promote any frozen precip. && .LONG TERM... (Tuesday morning through next Saturday) Issued at 127 PM EST Sun Dec 7 2025 Tuesday and Wednesday are still on track to bring dry, sunny to mostly sunny conditions. Wednesday still looks to be noticeably warmer than Tuesday, as the airmass modifies and surface/low- level flow shifts from northerly to westerly in response to a northern stream shortwave/jet streak that will dive southward and eastward across the Ohio/Tennessee River Valleys. PoPs are lower on Thursday (only up to 20%) with this forecast package, and relegated to along and north of I-85, as the Pacific moisture accompanying said shortwave looks to be meager this far south. Showers (if they even occur) should be light and not amount to much rainfall. Ensemble guidance shows a stronger shortwave/jet streak barreling eastward across the central tier of the eastern CONUS Thursday evening into the weekend. This feature will drive a strong northwest flow, cold-air advection (CAA) response at/near the surface, evidenced by our current forecast for overnight/early morning lows to go from the mid-30s to mid-40s on Friday to the upper teens to lower 30s on Saturday. If this forecast comes to fruition, we could be greeted with some of the coldest air of the season thus far. && .AVIATION... (18Z TAFS) Issued at 1221 PM EST Sun Dec 7 2025 IFR to LIFR through much of the period. Reduced vsbys likely to remain through 18z with cigs holding below 015 through period. Showers move through overnight with cigs falling back to LIFR for all TAF sites through tomorrow morning. Conditions will be slow to improve tomorrow. Winds light and variable, generally E, pick up after rain tonight out of NW around 15z. //ATL Confidence...18Z Update... Medium confidence vsby. High all other elements.

An area of low pressure tracks from northeastern New York Sunday evening to near southeastern Nova Scotia early Monday morning. High pressure builds in behind this system through Monday night, then slides offshore on Tuesday. Another weak low tracks across the Gulf of Maine Tuesday night. A stronger low pressure system tracks from the Great Lakes Wednesday morning to the southern Canadian Maritimes by Thursday morning, followed by a cold front crossing the area on Thursday. && .NEAR TERM /THROUGH MONDAY NIGHT/... Snow will spread across the southern tier of the forecast area late tonight and continue over night as a weak low pressure system passes just offshore. The low will strengthen slightly as it moves into southern Canada, enhancing QPF over the southeastern corner of the state. Although snowfall will be fairly minimal for the rest of the area, including Bangor, 3 to 5 inches is expected over southern Washington County. A winter weather advisory has been issues for this area. Behind the low, winds will increase with high pressure building in, mainly offshore with the northern flow. See more detail in the marine section. As for the land, the high building in will also bring another round of very cold air, so temperatures Monday and Monday night will be well below normal, and below 0F in many locations. && .SHORT TERM /TUESDAY THROUGH WEDNESDAY/... Key Messages -Light snow accumulation Tuesday night -Larger system approaches Wednesday with snow and rain The high pressure system exits over the waters on Tuesday, making for clear skies in the morning. Clouds start to move in in the afternoon as the next low approaches. A warm frontal boundary should stretch well to the north, switching winds to onshore flow. For Tuesday night, with weak low pressure system should move into the region. The onshore flow should keep temps above zero, though in the single digits or teens across the area. The weak low pressure system should bring some light snow across the area with higher amounts round 2 inches in Downeast. For Wednesday, a larger low pressure system moves in later in the day. Warmer S flow should push temps into the 20s in the north and upper 30s in the south. Snow is expected to be light in the afternoon with higher amounts in the Central Highlands. Areas south of the Central Highlands should see a mix of rain/snow or rain. && .LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/... Key Messages -Active period with cold single digit nighttime temperatures The low pressure system should exit the area by Thursday, making for warmer temps, breezy winds, and cloudy skies. Upper level models show a fairly active extended period as the upper level trof swings through one shortwave after another. The further south jet stream puts the area in the left exit region, thus a more active area. The models lose consistency towards the end of the week due to uncertainty of the trof pattern. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... NEAR TERM: VFR today. Conditions deteriorate to MVFR tonight after 0z for southern terminals with light snow and after 3z for northern terminals with snow showers. Snow may reduce visibility to IFR for brief periods, mainly at southern terminals. Conditions improve to VFR Monday morning. Light and variable winds becoming northerly 10 to 15 kts with gusts 20 to 25 kts Monday. SHORT TERM: Tuesday...VFR. W winds becoming S 5-10 kts. Tue night...MVFR/IFR in snow. Light S winds. Wed...MVFR/IFR in snow north and rain south. SSE winds 5-10 kts. Wed night...MVFR in exiting snow. Variable winds around 5 kts. Thu...MVFR early, then VFR. W winds 5-10 kts. Fri...VFR. W winds 5-10 kts. && .MARINE... NEAR TERM: Winds are currently below SCA criteria but are expected to increase above 25kts late tonight, then build to a short period of gales over the outer waters tomorrow morning. Winds will decrease below 35 kts by afternoon, but continue to gust to around 25 kts through tomorrow evening. Seas will build to 4 to 5 feet tonight through late tomorrow. SHORT TERM: SCA conditions expected Tuesday. Could see a return to gale force conditions Tuesday night, otherwise SCA conditions are likley mid to late week. && .CAR WATCHES/WARNINGS/ADVISORIES...
