551 FXUS62 KFFC 222343 AAA AFDFFC Area Forecast Discussion...UPDATED National Weather Service Peachtree City GA 743 PM EDT Fri Aug 22 2025 ...New 00Z Aviation Discussion... .SHORT TERM... (This afternoon through Saturday) Issued at 231 PM EDT Fri Aug 22 2025 Key Messages: - Flood Watch across portions of east and east central Georgia. Areas within the watch could see 4+" of rainfall Today and Saturday from slow moving thunderstorms. Flood Watch is in effect until 2am Sunday. Forecast: Scattered showers and thunderstorms across the region but expecting more coverage as we go into the evening hours. The frontal boundary that pushed into N GA yesterday is moving very slowly south. It almost appears to have stalled across the ATL/AHN areas and is acting as a focal point for the developing storms. Easterly flow along with a surface ridge/pseudo wedge building into NE GA will pull in additional moisture from the Atlantic, which keeps forecast PWAT values 2" or higher across much of the CWA Today and Sat. This is a very weak wedge with light surface winds so any storms that develop will be relatively stationary, which further increases the potential localized rain totals and some possible flooding. Most areas should see 1" to 3" totals with some isolated 4" to 5" totals through Sat night. Flash Flood Guidance across the area is typically pretty high thanks to soil type, especially in the summer where ground and plant uptake of water is very high, but relatively heavy rains over the past few days have preconditioned soils in some locations, and the rainfall rates could easily overwhelm some areas (especially more urban areas). Have continued with the current Flood Watch across portions of east and east central GA with all this in mind. With the cloud cover and expected rain temps will be mainly in the 80s across the CWA with some 70s in the NE GA mountains. Low temps tonight and Sat night will be in the 60s and 70s. 01 && .LONG TERM... (Sunday morning through next Thursday) Issued at 231 PM EDT Fri Aug 22 2025 Key Messages: - Cooler and drier as we start next week. - Little to no thunderstorm activity expected. The long term picks up just ahead of a cold front that will sweep the remains of the stationary front out of our CWA and establish a taste of fall for most of the forecast area. Temps will run below average for late August with highs in the low to mid 80s and overnight lows in the 60s. The front will have the added bonus of flooding the area with dry air, and our minimum RH values will fall into the 40s nearly every day. Overall we`re expecting extremely nice conditions through the long term. High pressure and dry air will keep thunderstorm chances limited to nearly zero all week. A few of the models are signaling at least a chance for some showers and thunderstorms to return to the CWA by next weekend, but even those chances are on the marginal side given how far out in the future we`re talking. Vaughn && .AVIATION... (00Z TAFS) Issued at 723 PM EDT Fri Aug 22 2025 Scattered convection is pushing across the state from east to west this evening. Expecting that the most likely time frame for TSRA at the TAF sites will be 00z-02z, although VCSH/SHRA will be possible outside of that time frame. CIGs will drop overnight, with widespread IFR expected. LIFR CIGs (and reduced VIS) will be possible, especially where rain occurs this evening. Similar to today, CIGs may be slow to improve tomorrow (Saturday) with MVFR well into the afternoon. Winds will remain out of the east at 5-10 kts through the TAF period (with some sites going light/VRB to calm overnight). //ATL Confidence...00Z Update... Medium confidence on LIFR potential. High confidence on all other elements. Martin && .PRELIMINARY POINT TEMPS/POPS...
