973 FXUS62 KFFC 292337 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 737 PM EDT Sat Jun 29 2024 ...New 00Z Aviation Discussion... .SHORT TERM... (This afternoon through Sunday) Issued at 222 PM EDT Sat Jun 29 2024 Pretty cut and dry (or I guess wet) this afternoon. Basically the same story as yesterday, scattered showers and thunderstorms with locally heavy rainfall, gusty winds, and frequent lightning. Not expecting much in the way of widespread accumulations and some areas could receive no rain at all. PoPs drop off overnight, however a few remnant sprinkles remain possible through tomorrow morning. Rinse and repeat tomorrow with chaotic isolated showers and thunderstorms late morning into the afternoon. The real story will be the heat. With humidity returned to the area combined with a narrow ridge, heat indices will be steamy tomorrow afternoon. A heat advisory has been issued for a large portion of Central and East-Central GA due to potential heat indices of 105 to 107. We will continue to watch our heat risk through early next week. SM && .LONG TERM... (Monday morning through next Friday) Issued at 222 PM EDT Sat Jun 29 2024 At a glance: -A trough on Monday will stall a front across central GA. This will bring a break from the heat for northern GA. -Afternoon thunderstorms are possible through the long term. The long term picks up as high pressure begins to break down across the SE. An upper level low situated over the northern Great Lakes will drag a trough through what has been a pretty stagnant atmosphere for the past week. This front is expected to stall out across the southern portion of the CWA where it will act as a focus for afternoon showers and thunderstorms on Monday and Tuesday before High pressure starts to build in once again. Behind this front, temps will ease into the mid to upper 80s on Monday and Tuesday for much of northern and some of central GA. Unfortunately, that will be pretty short lived. As another Bermuda high sets up, temps will start to climb back into the 90s by Wednesday. A surge in moisture once we set up on the west side of the ridge will cause our heat indices to spike into the triple digits toward the end of next week. The tropics are starting to act up and an increase in tropical moisture across our area is possible as Tropical Storm Beryl enters the gulf. Most model guidance seems to indicate that Beryl will not threaten the gulf coast. Vaughn && .AVIATION... (00Z TAFS) Issued at 733 PM EDT Sat Jun 29 2024 Sct SHRA and iso TSRA will continue to diminish in coverage through 02Z. Though patchy fog or areas of lower cigs are possible, largely VFR conditions are favored to persist tonight into Sunday morning. Sct SHRA and TSRA are again expected Sunday afternoon, especially after 18Z. Winds overnight will be light at 5 kts or less from the SW to near calm. Expect NW winds at 5-10 kts on Sunday. //ATL Confidence...00Z Update... Medium confidence on morning cigs and precip timing. High confidence on other elements. RW && .PRELIMINARY POINT TEMPS/POPS...
