FXUS62 KFFC 081735 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 135 PM EDT Wed Jul 8 2026 ...New 18Z Aviation Discussion... .KEY MESSAGES... - Isolated to scattered (15-30%) showers and thunderstorms possible each afternoon and evening, increasing through the weekend. A few storms may become strong with wind gusts up to 40-50mph. - Heat index values peak each afternoon between 95 and 105. Heat advisory for portions of Southeast GA Today. && .SHORT TERM... (Today through Thursday) Issued at 326 AM EDT Wed Jul 8 2026 Current satellite loop shows mostly clear skies across the area this morning. A slightly drier airmass has moved in across the region which should help keep diurnally driven convection to a minimum this afternoon. We are still under West to Southwesterly flow with temps again expected in the 90s so some isolated showers and thunderstorms area still expected this afternoon and evening. SPC has the entire state under a general thunderstorm risk today. Best timeframe for convective storms looks to be between 2-10PM. Moisture begins to slowly increase across the region Thu so will see another round of afternoon showers and thunderstorms but becoming more scattered in coverage. && .LONG TERM... (Thursday night through Tuesday) Issued at 326 AM EDT Wed Jul 8 2026 Heading into the latter part of the week and weekend, flow aloft becomes more broad while the Bermuda high continues to churn over the Atlantic. Southwest winds return, advecting moisture into the southeast once again. For this, shower and thunderstorm chances increase into the weekend. By the end of the weekend, flow aloft responds to a stout ridge building out west, turning upper winds N/NW. At the surface, guidance does indicate a weak frontal boundary that could cross the area toward the beginning of next week. If this materializes, a brief period of drier air and a small break from the heat. Long range models show northern Georgia highs in the mid to upper 80s by Sunday with low 90s elsewhere. Overall, diurnally driven shower and thunderstorm chances daily and some cooler temps possible over the weekend. && .AVIATION...
