684 FXUS62 KFFC 100017 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 717 PM EST Sat Nov 9 2024 ...Evening Update... .UPDATE... Issued at 714 PM EST Sat Nov 9 2024 No major adjustments to the forecast at this time. The big challenge over the next 24 hrs will be keying in on the wedge`s reaction to the stalling front and increased Atlantic moisture. Current models continue to try pinching off flow supporting the wedge allowing it to break down, however low level dry air will likely be more stubborn to move than that. Either way, moisture within the wedge region should moisten through tomorrow and fog may become a hazard Sunday night into Monday morning. && .SHORT TERM... (This afternoon through Sunday) Issued at 218 PM EST Sat Nov 9 2024 Wedge front continues to move in from the NE this afternoon. The wedge is well depicted within the dewpoint field. In addition, right along the edge of the wedge isolated/scattered showers have developed. A cold front is currently across the central portion of the US. This boundary will move slowly east through the period, funneling tropical moisture northward from the GOMEX ahead of it. The wedge is currently depicted by the intrusion of drier dewpoints, but this should change as low level moisture off the Atlantic increases. Shra will be likely across the eastern half of the CWA overnight. The cold front out west will also slowly drop southeast during the day Sunday into Sunday night, bringing higher chances for rain to the NW portions of the state. The front will likely weaken as it moves south and away from the best mid level forcing. Higher winds tonight should keep any fog and/or dense fog patchy. However, widespread fog and/or dense fog is possible Sunday night into Monday morning. NListemaa && .LONG TERM... (Monday morning through next Friday) Issued at 218 PM EST Sat Nov 9 2024 Key Messages: - Temperatures run 5-10 degrees above average for November Monday and Tuesday. Some light rain remains possible Monday. - Another system may bring rain chances by the middle to end of next week. Forecast: By Monday, the upper level system responsible for the weekend rainfall will be moving out of the northeast with another shortwave riding in behind it. Given how far north the upper level forcing is, the cold front will become aligned with the upper level flow and likely stop over the CWA. Some moisture along it may be able to squeeze out some additional rainfall through the day, but this looks to be isolated to scattered at best. One caveat may be that a little bit of the leftover moisture from the likely decayed tropical system may be able to make its way into the area, which could bring some additional rain. The only other story with this will be that the high temps both Monday and Tuesday will be 5-10 degrees above average across the area. By Wednesday, strong surface high pressure looks progged to set up shop over the northeast. Looking very likely we get wedged for the 400th (mild exaggeration) this fall. After this, uncertainty gets a bit higher. Another system is expected to approach the area with a negatively tilted trough into Thursday. Models had been trending a bit drier, but the most recent runs on the Euro side have suddenly gotten a bit more moist, with the operational run really going in on the rainfall. The GFS and GEFS continue to show a front again losing forcing before reaching the area, limiting rainfall chances. Current forecast continues with more limited PoPs Thursday, as want to see more consistency out of Euro suite, especially given some of the struggles it had with the system in the Gulf. Lusk && .AVIATION... (00Z TAFS) Issued at 626 PM EST Sat Nov 9 2024 MVFR to low VFR conditions will gradually deteriorate through Monday morning. Return to IFR during day tomorrow and low IFR by afternoon. -SHRA around wedge front, most likely on western ATL, though could extend into eastern ATL. Winds remain on east side, tapering off Sunday afternoon/evening. As winds decrease, FG will likely develop over central GA and expand across the region through Monday morning. Low VSBY and Cigs are possible. //ATL Confidence...00Z Update... Medium confidence all elements. SM && .PRELIMINARY POINT TEMPS/POPS...
