189 FXUS62 KFFC 300603 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 203 AM EDT Sun Jun 30 2024 ...New 06Z 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... (06Z TAFS) Issued at 142 AM EDT Sun Jun 30 2024 Areas of low cigs have developed from near MCN to CSG. Models expand these cigs northward mostly W of the Atlanta metro area prior to daybreak. However, a scattered deck between 500 and 800 feet may affect the metro area early this morning. Morning multi- layered clouds will likely delay convection today, but scattered showers and thunderstorms are expected to develop this afternoon. The best chances of thunderstorms are expected S of a pre-frontal boundary from CSG to MCN. Additionally, more storms are possible along a weak cold front sagging into N GA late in the afternoon. //ATL Confidence...06Z Update... Medium on morning cigs and precipitation timing, high on other elements. SEC && .PRELIMINARY POINT TEMPS/POPS...
