763 FXUS62 KFFC 161858 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 258 PM EDT Wed Jul 16 2025 ...Afternoon Area Forecast Discussion... .SHORT TERM... (This afternoon through Thursday) Issued at 214 PM EDT Wed Jul 16 2025 - Hot and muggy conditions will persist through Thursday with heat index values as high as 100-104 expected Thursday afternoon. - Only isolated diurnal showers and thunderstorms are expected this afternoon and Thursday afternoon. The most recognizable feature on satellite this afternoon is the spin of the weak low pressure disturbance over the western Florida panhandle. Locally, there will not be too much impact from this feature with the exception of a plume of deeper tropical moisture that will skirt primarily our southwestern counties. Any shower and thunderstorm activity this afternoon will be isolated with slightly higher coverage possible in these southwest zones. Convection will then quickly wane with the loss of diurnal support after sunset. Little in the way of change can be expected on Thursday. The midlevel ridge centered over the western Atlantic will expand its grip farther westward across the area as the aforementioned weak low moves toward the southeastern Louisiana coast. As such, high temperatures are likely to be a couple of degrees warmer than today, ranging from the low to mid 90s areawide outside of the mountains. Afternoon apparent temperatures will likely reach the 100-104 range across the bulk of the area Thursday afternoon with a few spots potentially nudging 105, though these values should be isolated and transient enough to preclude a Heat Advisory. Any afternoon/early evening convection will again be quite isolated before diminishing after sunset. RW && .LONG TERM... (Friday morning through next Tuesday) Issued at 214 PM EDT Wed Jul 16 2025 - Isolated to scattered thunderstorms through much of the long term, including the weekend. - Weekend heat remains a concern, with the potential for temperatures in the upper 90s to near 100, and Heat Index values forecast to reach 106-110. Isolated to scattered showers and thunderstorms will continue with daytime heating through the extended period as ample moisture remains trapped under the subtropical ridge. Overall, though, the forecast trend has trended the PoPs down slightly in favor of a slight uptick in temperatures. Heat Advisories will likely be needed in the long term, and as early as Friday or Saturday. The oppressive, humid conditions will likely push temperatures into the upper 90s to near 100 across much of the area, with Heat Index values nearing 110 in some portions of central and eastern Georgia by Sunday. Into next week, the heat and diurnal convection continues, as is typical around here during the dog days of summer. 31 && .AVIATION... (18Z TAFS) Issued at 109 PM EDT Wed Jul 16 2025 VFR conditions are expected to prevail through the TAF period. Only iso SHRA/TSRA are possible through 00Z this evening before diminishing. Additional iso SHRA/TSRA are possible after 18-20Z Thursday. SSE wind direction is expected to be predominant through tonight, though direction will likely vary between SSE and SSW by Thursday morning before trending more SSW after 18-21Z Thursday. Speeds will be 6-10 kts through 00Z, 5 kts or less overnight, and 5-10 kts on Thursday. //ATL Confidence...18Z Update... Medium confidence on wind direction tonight into Thursday morning. High confidence on other elements. RW && .PRELIMINARY POINT TEMPS/POPS...
