045 FXUS62 KFFC 120528 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 128 AM EDT Sat Jul 12 2025 ...New 06Z Aviation Discussion... .SHORT TERM... (This afternoon through Saturday) Issued at 148 PM EDT Fri Jul 11 2025 Key Messages: - Saturday will bring another day of scattered afternoon and evening thunderstorms. Some storms could become strong with locally heavy rainfall, frequent lightning, and brief gusty winds. - Heat index values as high as 98-104 are expected Saturday afternoon. Scattered thunderstorms are again erupting this afternoon within a moist and unstable environment. This activity will persist into the evening before gradually waning with the loss of diurnal support. Slow and meandering forward motion will present the risk for locally heavy rainfall that could lead to street or nuisance flooding concerns. Additionally, frequent lightning and brief gusty winds can be expected. Saturday brings no significant forecast changes with continued anomalously deep Gulf moisture characterized by PWATs of 1.75-2.10" remaining in place. Scattered thunderstorms can again be anticipated Saturday afternoon and evening, though coverage may begin to trend slightly downward as the midlevel subtropical ridge begins to build over the Southeast. Again, locally heavy rainfall, frequent lightning, and gusty winds will be a concern with any storm, though widespread severe thunderstorms are not expected. Temperatures on Saturday will also begin to trend upward as ridging starts to build. Highs should step upward a couple of degrees as compared to today, largely into the low to mid 90s. Apparent temperatures will push back above 100 for most areas. A few spots in east central Georgia could briefly reach 105 degree heat index values, but the spotty and transient nature will preclude any Heat Advisory issuance at this time. RW && .LONG TERM... (Sunday morning through next Thursday) Issued at 148 PM EDT Fri Jul 11 2025 At a glance: - Thunderstorm coverage in the afternoon will ease this weekend and the start of next week as high pressure temporarily stalls over GA. - Temperatures will steadily rise, and heat indices could rise back into the triple digits. Some good news, the forecast is beginning to show the possibility of easing thunderstorm coverage late this weekend and early next week. Given the time of year and the principles of thermodynamics, we won`t see the end of afternoon convection all together. However, the coverage and the intensity will likely be limited as a result of a building high pressure heat dome that will likely push temps into uncomfortable late this weekend and into the early part of next week. Temperatures are also going to slowly become more and more of an issue as we get into the weekend. High temps will be pushing mid to upper 90s with triple digit heat indices possible, especially in the southern parts of the CWA. As we move into the middle part of next week, afternoon thunderstorms will likely return to the CWA. High pressure moves off the coast, and moisture will likely return to the area to provide the ingredients for daytime convection. No indication of any front driven storms, but as always a few storms during this time will likely be strong to severe. Vaughn && .AVIATION...
