178 FXUS62 KFFC 301837 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 237 PM EDT Sat Aug 30 2025 ...Afternoon Area Forecast Discussion... .SHORT TERM... (This afternoon through Sunday) Issued at 236 PM EDT Sat Aug 30 2025 Key Messages: - Areas of patchy fog could occur in central Georgia between 4 AM and 9 AM Sunday. - Isolated thunderstorms could be a hazard for outdoor activities in the north Georgia mountains between 1 PM and 7 PM Sunday. Rest of Today & Tonight: The area of low pressure that created an unusual degree of uncertainty in the forecast over the last 48 hours was centered near Pensacola this afternoon. It has taken the more southerly track advertised the the GEFS guidance, largely due to the more southerly positioning of a stationary front. This has allowed more sunshine than expected in north Georgia today, and temperatures have responded by climbing into the 80s. For areas south of a line from Columbus to Macon thicker cloud cover and rain showers have limited temperatures to the 70s. Significant clearing is unlikely in this area, so afternoon highs should remain below 80 degrees. A few light rain showers could pop up across north and central Georgia this afternoon. Thunder is unlikely though due to a lack of instability and any rainfall should be brief in nature. Most locals can expect to remain dry through sunset. This mornings rainfall, light winds and clearing skies could promote some patchy fog development over central Georgia tonight. If fog forms it would most likely occur between 4 AM and 9 AM Sunday. A Dense Fog Advisory probably won`t be required (< 10% chance). Sunday: As today`s area of low pressure drifts into the Atlantic and a surface high settles in over the Great Lakes, a pseudo wedge will develop and bring northeast winds to Georgia. This will lead to mild and mostly dry weather in Georgia on Sunday. Expect morning lows in the mid 60s and afternoon highs in the lower 80s. The exception to the dry conditions may be the north Georgia mountains. Weakly convergent surface flow (northwest surface flow coming from Tennessee and northeast flow from the wedge) should combine with differential heating over higher terrain to produce a favorable environment for afternoon convection. Moisture won`t be overly impressive, but with convective temperatures in the 70s, surface dewpoints in the near 60 should be sufficient. The peak time window for any convection should be between 1 PM and 7 PM. Some lightning could occur, though marginal lapse rates (< 5.5 C/km between 700-500 mb) and elevated freezing levels suggest limited coverage. Those participating in outdoor activities over the holiday weekend should monitor the lightning threat. Albright && .LONG TERM... (Monday morning through next Friday) Issued at 236 PM EDT Sat Aug 30 2025 Key Messages: - A system moves across the state Wednesday with increased rain chances, but otherwise mostly dry conditions through next week. - Slightly below normal temperatures through next week. Early next week, deep mid-level troughing will remain parked over the Eastern US, resulting in persistent low to mid-level NW flow across the state. Surface high pressure beneath the Eastern US trough will keep a shallow NE flow (similar to a wedge) over the area. Overall this setup will lead to mostly cloudy and slightly cooler than normal conditions, with enough atmospheric moisture (PWAT values 1-1.5") to support only isolated rain chances each day. Around mid-week, a stout mid-level shortwave and associated surface low will be dropping along the backside of the trough across the Lower Mississippi Valley. As the system approaches the area, low to mid-level flow will turn out of the south, bringing in a surge of warm and moisture with PWAT values climbing up to 1.75-2". This moisture combined with large scale forcing from the system will lead to scattered showers and thunderstorms, with the best chances across central GA. Depending on the timing of this system, we could even see some strong to severe storms, though confidence in any severe threat is very low at this time. The cold front associated with this system will rapidly push through behind it, leading to the return of a dry and cool airmass through the end of next week and into the weekend. Culver && .AVIATION... (18Z TAFS) Issued at 121 PM EDT Sat Aug 30 2025 Isolated showers will occur in north and central Georgia through 03Z Sunday, impacts are unlikely (<15% chance) at the TAF sites. Areas of patchy fog or low ceilings (200-2000) are possible in central Georgia between 06Z and 14Z Sunday. Winds will continue to be from the east (060-120 degrees) through 00Z, then variable winds are anticipated between 00Z and 14Z Sunday. Northeast (050-100 degrees) winds in the 4 to 12 kt range are expected between 14Z Sunday and 00Z Monday. //ATL Confidence...18Z Update... High confidence in all elements of the KATL TAF.
