185 FXUS62 KFFC 111851 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 251 PM EDT Tue Aug 11 2026 ...Afternoon Area Forecast Discussion... .KEY MESSAGES... - Isolated damaging wind threat is possible late tonight and again on Wednesday as NW flow keeps waves moving into the area. - Scattered thunderstorms will be possible each day this week posing a threat for gusty winds and locally heavy rainfall. - Impactful heat is becoming increasingly likely as heat indices return to the mid 90s to low 100s by the middle of the week. && .SHORT TERM... (This afternoon through Wednesday) Issued at 157 PM EDT Tue Aug 11 2026 Current radar loop shows scattered showers and thunderstorms developing across the area this afternoon. storms are mainly across NW GA and central GA as there is a weak wedge of high pressure building down the eastern seaboard into NE GA. Like the past few days we are mainly expecting these storms to stay below severe thresholds but can not rule out an isolated severe storm or two popping up. PWATs are currently in the 2"-2.2" range with MU Cape around 1500 to 2500 J/Kg and LIs in the -5 to -7 deg range. Not much sheer available so looks like the greatest convective threats are periods of heavy rain, frequent lightning strikes, small hail, and strong gusty winds. Wednesday will be much of the same as the wedge builds in a bit further with NW flow keeping things going. Temperature Wed will be very similar to today with highs in the upper 80s to the middle 90s. && .LONG TERM... (Thursday morning through next Monday) Issued at 157 PM EDT Tue Aug 11 2026 As the long term sets up, a strengthening ridge will be building in for the weekend. Chances for afternoon storms will start to decline, while the risk for excessive heat ramps up. By Friday, most of the CWA can expect apparent temperatures in the triple digits with the eastern part of the forecast area reaching Heat Advisory criteria. We`ll need to keep an eye on temps over the next couple of days, but if you have plans for this coming weekend, keep the heat in mind. That`s what we do know. Now for what we don`t... Over the next couple of days we`ll be transitioning into NW flow. This kind of pattern is notorious for letting MCS` make a big run across half the country and end up on our doorstep. Long term models struggle to pick these out from the noise, and as a result we`ll just need to wait and see how the ridge sets up over the next few days. These ridge riders also have a habit of interrupting forecasted high temperatures with the introduction of rain, making the long term forecast a bit on the tricky side. && .AVIATION... (18Z TAFS) Issued at 1236 PM EDT Tue Aug 11 2026 Scattered showers and thunderstorms across the area this afternoon. All of the TAF sites will have a chance to see a SHRA/TSRA go across the airfield over the next few hours. These storms will diminish after sunset with another round of storms expected again Wed afternoon/evening. Winds mainly out of the W-NW in the 5-10kt range. Will see gust in the 15-25kt range in and around convection. VSBYs and ceilings are in the VFR range but will see some MVFR to IFR readings in and around storms. //ATL Confidence...18Z Update...
