220 FXUS62 KFFC 101833 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 233 PM EDT Thu Jul 10 2025 ...Afternoon Area Forecast Discussion... .SHORT TERM... (This afternoon through Friday) Issued at 230 PM EDT Thu Jul 10 2025 Key Messages: - As was the case today, Friday will bring another day of scattered afternoon and evening thunderstorms. A few storms could produce locally heavy rainfall and strong wind gusts. - Heat index values as high as 98-104 are again expected Friday afternoon. Scattered to numerous showers and thunderstorms are ongoing this afternoon within a moist and unstable environment characterized by analyzed MUCAPE of 2500-4000 J/kg and PWATs of 1.75 - 2.10". Both a Marginal Risk for severe thunderstorms as well as for excessive rainfall blanket most or all of the area through this evening. Given the deep Gulf moisture in place, any training or backbuilding thunderstorms could produce cause localized street flooding or flash flooding. As far as the severe threat is concerned, locally damaging water-loaded downburst winds would be the primary concern. All of this widespread convection will gradually wane by late evening with the loss of diurnal support. Friday will bring a more or less copy/paste forecast as little in the way of appreciable pattern change will occur. Scattered diurnally-enhanced thunderstorms will again develop by early afternoon and peak in coverage during the late afternoon and evening hours. Again, locally heavy rainfall could present sporadic street/flash flooding concerns, and a few strong to isolated severe thunderstorms may bring strong downburst wind gusts. While conditions will be hot and humid, temperatures and apparent temperatures will remain largely below Heat Advisory criteria through Friday. Expect highs from the upper 80s to low 90s for most areas Friday afternoon with maximum heat index values reaching as high as 102-104 in portions of central and east-central Georgia. While a few spots could flirt with 105 apparent temperatures, these values should be short-lived in the midst of increasing convection. RW && .LONG TERM... (Saturday morning through next Wednesday) Issued at 230 PM EDT Thu Jul 10 2025 At a glance: - Thunderstorm coverage in the afternoon will continue through next week. - Temperatures will steadily rise, and heat indices could rise back into the triple digits. The long term forecast is going to be pretty much stuck on a rinse and repeat cycle of afternoon thunderstorms with hot and humid conditions. Gulf moisture will continue to be injected into the southeast under an upper level high pressure just off the Atlantic coast. This is a pretty typical summertime pattern and we`re not seeing any indication that a strong enough ridge out of the west is going to break it. As a result, afternoons will be hot with isolated thunderstorms that could be strong to severe depending on diurnal heating and the presence of any meaningful wind shear. 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. So if you have plans outside this weekend, just make sure you`re staying hydrated and keep an eye on kids and pets too! Vaughn && .AVIATION... (18Z TAFS) Issued at 116 PM EDT Thu Jul 10 2025 Sct SHRA/TSRA are ongoing and will persist through the afternoon before gradually tapering after 00-02Z. Outside of convection, VFR conditions are largely expected. There is some potential for patchy IFR cigs by 10-12Z Friday, though confidence in coverage is not high. Sct SHRA/TSRA are again expected after 18Z Friday. Winds will remain W at 5-10 kts and less than 5 kts overnight. //ATL Confidence...18Z Update... Low to medium confidence on morning IFR potential. High confidence on other elements. RW && .PRELIMINARY POINT TEMPS/POPS...
