085 FXUS62 KFFC 240742 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 242 AM EST Sat Jan 24 2026 ...Morning Area Forecast Discussion... .KEY MESSAGES... Updated at 223 AM EST Sat Jan 24 2026 - An Ice Storm Warning is in effect from Saturday into Monday for most of north Georgia due to an impending high-impact ice storm. Widespread power outages and difficult to impossible travel are expected across this area. Additionally, the Winter Storm Watch in effect elsewhere has been upgraded to a Winter Weather Advisory. - Dangerously cold nighttime temperatures from Monday to potentially Thursday will be an added concern for those still without power and vulnerable populations. Tuesday morning will be of particular concern, when "feels like" temperatures are forecast to be in the single digits for many across north and central Georgia. - Now is the time to review your family`s emergency plan and make preparations for hazardous weather. && .SHORT TERM... (Today through Sunday) Issued at 223 AM EST Sat Jan 24 2026 What Has Changed: The Winter Storm Watch across the central portion of the County Warning Area (CWA) has been UPGRADED to a Winter Weather Advisory. Pike, Lamar, and Monroe Counties were added to this Advisory, as a light glazing of ice could make for hazardous travel. Ice Storm Overview: Our confidence remains high that a significant ice storm will impact much of north Georgia this weekend. The BOTTOM LINE UP FRONT is that ice accumulations of at least a quarter inch are probable within the Ice Storm Warning area, with high confidence in peak accumulations in the textbook "wedge" area (cold air damming area) -- the northeast quadrant of the CWA. Across this area, widespread ice accumulations of a half inch to three- quarters inch are probable, with localized amounts approaching one inch. Also want to note that the foothills and mountains across north Georgia (including those in far northwest Georgia) are likely areas for maximized ice accumulations, due to orographic lift. Those within the Ice Storm Warning should prepare for widespread and long-lasting power outages (as winds will be gusting to 20-30 mph) as well as difficult to impossible travel. Note that the Ice Storm Warning begins this morning (Saturday) at 7 AM for far northwest Georgia, to capture the potential for early onset of light frozen precipitation. The Ice Storm Warning begins at 1 PM today for the remainder of north Georgia, as precip spreads eastward. Those in the Winter Weather Advisory that was issued earlier this morning should be prepared for a light glazing to a tenth of an inch of ice accumulation, which could make travel hazardous. Forecasting the Wedge: We have talked a lot in previous Area Forecast Discussions (AFDs) about the wedge/cold air damming footprint and strength, and its impact on the severity of this ice storm. A skilled blend of high- resolution model guidance was used to arrive at the temperature and dew point forecasts through the short term period, to capture the staying power of the wedge as precip reinforces its characteristic cold, surface-based airmass. The result is a forecast largely unchanged from yesterday afternoon`s shift -- the wedge and associated freezing rain (and some sleet) spreading southward and westward tonight through Sunday morning. The wedge should begin to erode along its southern and western fringes on Sunday afternoon and evening as Gulf low pressure shifts northeastward across the area. That said, for parts of northeast Georgia in the core of the wedge airmass, temperatures may not get much above freezing (if at all) on Sunday afternoon. This may include cities/towns such as Dahlonega, Dawsonville, Gainesville, Suwanee, Lawrenceville, and Athens. Central Georgia Thunderstorms on Sunday: Advection of warm, moist air courtesy of the aforementioned Gulf low may support thunderstorms across central Georgia on Sunday when coupled with strong winds/speed shear aloft from a strong trough. The potential for strong or severe storms remains conditional, meaning that the potential will depend on how far north the warm, humid air surges into the CWA. Potential hazards would include damaging wind gusts and a brief tornado. && .LONG TERM... (Sunday night through Friday) Issued at 223 AM EST Sat Jan 24 2026 The Short Version: A very cold airmass will settle into the southeast on Monday. Cold temperatures will remain in place through the entire week and potentially into the weekend as yet another cold airmass filters into the area from the north. High temperatures are in the 30s and 40s for most each day. Overnight lows are concerning - teens and 20s will be in place for many areas each night. Of particular concern is Tuesday morning, where "feels like" temperatures will be in the low teens to single digits (and possibly lower in some areas up north, especially in the mountains). Cold Weather Advisories and potentially Extreme Cold Warnings may be needed on Tuesday morning. Finally, some signs of another potential winter event at the tail end of the forecast starting next week, but waaaaay too early to talk about anything with confidence given run to run variability. One storm at a time please, atmosphere. Discussion: On the one hand, the long term is the "easier" part of the discussion given the winter storm being discussed above. On the other, despite the lack of precipitating weather (at least until the very tail end - we will get there), there are still some impactful things to discuss. As the cold front sweeps through the area tomorrow night, precip will quickly come to an end behind it and cold air will rush into the area. Temperatures will fall into the 20s and some teens across north Georgia and parts of central Georgia (areas of east central Georgia may take a bit more time for the front to clear). Highs on Monday will be impacted by ice and potential sleet accumulations, and how much of those remain behind. Melting will keep temperatures lower as heat goes into melting the ice. Important to note that impacts from the ice storm will very likely remain into Monday in some areas and impact morning commutes. Even if all areas experience a switch over to rain, the cold front will ensure that temperatures fall back below freezing, locking in anything that is still in place. Aloft, the trough that brought our wintry weather will phase with another wave quickly diving out of the midwest and into the southeast on Monday. This will bring another reinforcing shot of the cold air as AVA pushes the cold, Arctic surface high even further south. Morning temperatures are currently forecast to be in the single digits to low teens across north Georgia, moving up to a "balmy" upper teens to low 20s across much of central Georgia. Factor in the potential for there to be at least some light NW winds occurring, and feels like temperatures will drop even lower. Unless significant changes occur, expect to see cold weather advisories and/or extreme cold watch/warnings hoisted in the coming days. Cold air sticks around and warms slightly thanks to sunshine and being in the South through Wednesday and Thursday. Upper level system looks progged to swing across the NE and push another cold front through the area Thursday night into Friday that should be dry, but just reinforce our already chilly airmass. Some uncertainty is noted as to whether or not that airmass makes it this far south - GEFS at ATL for 12Z Friday has the 10th percentile at 16F, median at 24F and 90th at 28F. NBM forecast is leaning towards the colder end. This airmass sticks around into the weekend, where things have the possibility of getting interesting once again. This is the part of the AFD where I get to do my favorite PSA - friends don`t let friends share single model runs of 10:1 snow totals 8 to 9 days out on social media. From any model. Yes, I am judging you for posting that GFS run. Anyway, while the operational version of the GFS keeps posting varying fun totals, the GEFS puts the probability of an inch across areas around 15-20%. The probability of 4" is basically 4%...a single member, most likely. So, let`s just pump the brakes on talking about the next storm, and wait for a bit more model consistency (the Euro ensemble, for instance, locates probabilities a bit further north than the American). We`ve got bigger fish to fry this weekend. && .AVIATION... (06Z TAFS) Issued at 110 AM EST Sat Jan 24 2026 MVFR to low-VFR CIGs will persist through the day. Scattered -SHRA are expected late this afternoon into the evening (PROB30 at ATL from 23z to 05z) and will give way to frozen precip overnight. Have -FZRA beginning at ATL at 05z at this time, but the onset time may be tweaked in subsequent TAF updates. -FZRAPL is currently forecast at the other metro sites and AHN, with -SHRA only at MCN and CSG. CIGS and VIS will drop in response to the precip -- likely to IFR and MVFR, respectively. ESE to ENE winds will be 5-13 kts sustained with gusts to 25 kts. Strong winds within a few kilometers of the surface will bear watching early Sunday morning due to LLWS potential. //ATL Confidence...06Z Update... Low to medium confidence on timing of transition from -SHRA to -FZRA. Medium confidence on CIGs. High confidence on all other elements. Martin && .PRELIMINARY POINT TEMPS/POPS...
