968 FXUS62 KFFC 131900 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 300 PM EDT Thu Jun 13 2024 ...Afternoon Area Forecast Discussion... .SHORT TERM... (This afternoon through Friday) Issued at 256 PM EDT Thu Jun 13 2024 Skies are partly to mostly sunny across the area today with early afternoon temperatures ranging from the mid 70s in the highest elevations of the NE to near 90 across the S third of the County Warning Area. Some lingering mid-level vorticity along with slightly cooler air aloft will generate a few showers across the NE mountains this afternoon and again Friday afternoon, but the remainder of the area should remain dry. Lows tonight will drop to near 60 in the highest elevations with mid to upper 60s elsewhere (perhaps closer to 70 in the Atlanta metro heat island). High temperatures on Friday will range from the mid to upper 80s in the northern mountains to the mid 90s elsewhere. Low temperatures Friday night will range from the mid 60s in the NE mountains to the lower 70s elsewhere. SEC && .LONG TERM... (Saturday morning through next Wednesday) Issued at 256 PM EDT Thu Jun 13 2024 Starting Saturday, long wave trough will be exiting the NE CONUS, dragging a stalling surface front slowly down towards the CWA. Our dry airmass that is currently in place will still be in place across the CWA, just now with several days worth of June sunshine beating down into it and warming it up. Upper level ridging will also be rapidly moving into the area Saturday and build fully over the area on Sunday. Surface high pressure slides off the east coast, bringing a more southerly fetch and moisture slowly returning to the area on Sunday. Add it all up, and it`s gonna be a hot weekend. Current forecast temps are well into the 90s and even approaching triple digits in many areas on Saturday. Forecast temps are a few degrees lower Sunday, but with the humidity, the overall heat index is similar to Saturday. Both days have heat indices into the upper 90s and lower 100s. Forecast morning lows on Saturday and Sunday start in the 70s in many locations, which should approach or break record maximum low temperatures in some areas if it comes to pass. With moisture slowly returning to the area, some afternoon thunderstorm chances will begin to pick up on Sunday despite dome of high pressure starting to build overhead. This ridge looks to potentially be in place through much of the rest of the long term. Still, these thunderstorms should remain pretty isolated thanks to aforementioned dome. Severe weather is not anticipated at this time, though will never rule out a damaging wind gust from a strong thunderstorm that collapses at the wrong time. Lusk && .AVIATION... (18Z TAFS) Issued at 139 PM EDT Thu Jun 13 2024 VFR conditions are expected to continue. Areas mostly NW and N of the Atlanta metro area may briefly go broken later this afternoon, but cig heights are expected to be around 7kft. Low-level moisture may sneak close to MCN from the SE toward daybreak Fri, but have left them mostly clear for now. Winds will be generally light easterly through the remainder of the day, becoming light and variable or calm this evening (have opted to keep ATL light easterly). A weak surface ridge is forecast to slip S of the Atlanta metro and AHN terminals late tonight or early Fri morning, with light winds becoming more W-NW. //ATL Confidence...18Z Update... Medium for timing of wind direction change to westerly Fri morning, high for all other elements. SEC && .PRELIMINARY POINT TEMPS/POPS...
