259 FXUS62 KFFC 221137 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 637 AM EST Thu Jan 22 2026 ...New 12Z Aviation Discussion... .KEY MESSAGES... Updated at 629 AM EST Thu Jan 22 2026 - A high impact ice storm is anticipated in northern Georgia this weekend. A Winter Weather Watch is in effect from 1 AM Saturday through Monday at 10 AM. - Significant impacts to travel are anticipated over the weekend due to both ice and snow, and power outages may occur. - Now is the time to review your families emergency plan and make preparations for hazardous weather. && .SHORT TERM... (Today through Friday) Issued at 215 AM EST Thu Jan 22 2026 Broad upper level troughing remains in place across the eastern CONUS as the morning begins. A shortwave rotating around the base of this trough is helping push a cold front into far northwest Georgia. Scattered showers are ongoing in portions of north Georgia ahead of this front, though remain light at this time as they struggle to overcome a layer of dry air near the surface. Over the next few hours, this dry layer will erode and more rain will be able to make it to the surface. Low temperatures this morning will be noticeably warmer than the previous couple of days, largely in the upper 30s to low 40s, with some mid 30s in the highest elevations of far northeast Georgia. This should prevent any wintry precipitation this morning and keep precip all liquid throughout the day. As the front continues to advance southward, scattered to numerous showers will persist through the day. Rain chances will be highest roughly along and north of the I-85 corridor, with progressively lower chances to the south and east. Rainfall accumulations through tonight will remain fairly light, between 0.25-0.5 inch along and north of I-85, with lower amounts to the south. High temperatures today will be a function of the front`s progression, and are expected to be mainly in low 50s in north Georgia and upper 50s to as high as 70 in central Georgia. Conditions will be similar on Friday as the frontal boundary stalls across central Georgia. Another round of scattered showers can be anticipated as a weak disturbance aloft overruns the stationary front. Showers will be most likely in central Georgia and are expected to be light once again, with totals less than 0.25 inch. In far north Georgia, temperatures are expected to drop into the mid 30s by sunset on Friday, at which point a light rain/freezing rain mix could develop. However, ice accumulations are not expected until the long term period. && .LONG TERM... (Friday night through Wednesday) Issued at 215 AM EST Thu Jan 22 2026 Ice Storm Overview The forecast for the weekend remains challenging with multiple low pressure systems developing, strong southerly moisture advection and an impressive (near 1050 mb) Arctic high moving in from the north. As all of these features come together a major winter storm will develop in the Eastern U.S. Impacts are expected for especially in north Georgia. Depending on how things play out with the wedge, impacts may extent into parts of central Georgia. A Winter Storm Watch remains in place from 1 AM Saturday to 10 AM Sunday for northern Georgia. The primary concern within the Watch area is the potential for significant ice accumulations, leading to treacherous travel and widespread power outages. Arctic air should move in as the event concludes early next week. This may keep temperatures at or below freezing for several days and extend the period of impacts for north Georgia early next week. Precipitation Onset on Saturday After some rainfall on Friday a break in the precipitation is anticipated as the second area of low pressure intensifies over the Southern Plains and ArkLaTex region. This break should occur Saturday morning (if model trends hold) as the wedge intensifies in response to a developing low along the Carolina Coastline and the surface high building into the Northeast. The airmass that will push into northeast Georgia with the wedge looks very dry, with some model runs suggesting surface dewpoints in the teens. This guidance is lower than the base NBM guidance, and this suggests a potential bias correction issue in the NBM that may be impacting how it is handling the wedge. In practical terms for the forecast this dry airmass suggests that the precipitation may restart on Saturday as a mix of sleet and freezing rainfall (as opposed to rain) due to evaporative cooling. This potential period of dry weather has potential implications for road treatment plans. It also raises the possibility of travelers being caught off guard by the sudden onset of wintry precipitation, especially in north Georgia Saturday afternoon. Wedge Intensity Over the Weekend Trends in the guidance, particularly the ECMWF, towards a warmer event have received quite a bit attention in the last 24 hours. While these trends are are potentially positive as they would support a rapid erosion of the wedge and less widespread ice accumulation in Georgia, they represent only a portion of the guidance. About half the EPS members keep temperatures in Atlanta 20 degree colder than the ECMWF on Sunday, while half the GEFS members keep the Atlanta near or below freezing through Sunday. These inconsistencies reflect the the models struggle to resolve the wedge and its potential strength. Historically models overestimate the ability of strong mid-level WAA to erode the wedge. This has been particularly true when the wedge is being reinforced by dry CAA and evaporative cooling. Given these considerations, we seem to be trending towards an event where we start off with a fairly widespread mix of light freezing rain and sleet on Saturday. As the southerly flow intensifies Saturday night and Sunday it may erode the southern edge of the wedge while the core of the wedges strength holds true in northeast Georgia. This would lead to contracting temperature gradients and a potential switch over to rain in parts of northwest and central Georgia. It wouldn`t be surprising if temperatures gradients between Athens and Macon exceeded 30 degrees on Sunday! Where the wedge traditionally holds strong in northeast Georgia icing may continue through the entire day on Sunday. Significant and very impactful ice accumulations of 0.25 to 1.25 inches may occur. As such the greatest risk for widespread power outages, tree damage and major travel impacts appears to be focused on northeast Georgia. A great deal of uncertainty remains regarding potential ice accumulations along an arc from Rome to Atlanta to Augusta. How much ice this area receives will depend entirely on how strong the wedge is. Some risk of freezing rain remains for central Georgia, especially Saturday and Saturday night, but at this time the trends for this area suggest a decreasing potential for significant impacts. Significant snowfall is unlikely with this event, unless it occurs during a brief window Sunday night and Monday morning. The main feature hindering snowfall should be the very strong warm nose aloft, which will melt any flakes and force them to become either sleet, freezing rain or rain before they reach the surface. To this end our forecast continues to trend towards little to no snowfall, with ice as the primary impact. Even the higher peaks of the mountains shouldn`t see much snow with this event. There may even be times when it is raining at elevations over 3500 ft, with freezing rain or sleet occurring below 3500 ft. A decidedly topsy turvey precipitation distribution. Cold Weather & Lingering Impacts Early Next Week A Arctic high will settle over the Southeast early next week. As this feature moves southward it will encounter potentially significant snowpack over the Tennessee Valley. This should help it maintain its intensity and potentially bring the coldest temperatures of the winter thus far to parts of Georgia. Temperatures may struggle to get above freezing in north Georgia Monday and Tuesday. For any areas with significant power outages this could lead to an extend period of significant impacts once the precipitation ends. This could apply to both travel conditions, clean up operations and the potential for pipes to freeze in buildings without power. The risk would be highest on Monday night and Tuesday morning when widespread low temperatures in the single digits and teen are possible under fair skies. && .AVIATION... (12Z TAFS) Issued at 629 AM EST Thu Jan 22 2026 As a cold front moves through north Georgia, -SHRA and MVFR ceilings have spread into the ATL sites and AHN as the period begins. IFR ceilings and moderate SHRA will be possible at times between 14-18Z at ATL, with a TEMPO being maintained for this time window. Prevailing IFR is then anticipated between 18-23Z before a relative lull in the rain and improvement back to MVFR tonight. Ceilings are VFR and will be largely between 050-070 at CSG/MCN, though -SHRA and MVFR level clouds will be possible at CSG during the morning hours. Winds will be NW at 4-7 kts to start the morning, and guidance is becoming more consistent in showing a shift to NE by 17-18Z and through the remainder of the period. Coverage of precip is expected to increase once again on Friday morning after 08Z. //ATL Confidence...12Z Update... Medium confidence on all elements. King && .PRELIMINARY POINT TEMPS/POPS...
