643 FXUS62 KFFC 161901 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 301 PM EDT Mon Sep 16 2024 ...Afternoon Area Forecast Discussion... .SHORT TERM... (This afternoon through Tuesday) Issued at 225 PM EDT Mon Sep 16 2024 Current satellite loop shows Mid level clouds streaming westward over the state, from the tropical system moving onshore the Carolina coast. The high pressure wedge is still dominating the weather pattern over GA with good easterly surface winds, but it is weakening. This tropical system rotating over the Carolinas is helping to bring in a drier airmass wrapping around the backside of the low center. This drier airmass is diminishing the cloud cover over the state that we have been under for the past few days. Most locations across the area will stay dry through the short term but We still will see a chance for some precipitation from this system. Eastern portions of the state that are closest in proximity to the storm will see a 20% to 30% chance of showers Tonight and Tuesday. Not expecting any thunderstorms. Temperatures tonight and Tuesday night will be mainly in the 60s. High temps Tuesday will be mainly in the 80s with some 70s across the NE GA mountains. 01 && .LONG TERM... (Wednesday morning through next Sunday) Issued at 225 PM EDT Mon Sep 16 2024 The period will begin with an upper trough extending from S New England to the E Gulf of Mexico. This feature will weaken and shift slowly E into the weekend. At the surface, several low pressure centers NE of the area will move off the mid-Atlantic coast with high pressure building along the Eastern Seaboard. This setup will once again produce a CAD wedge along the E side of the Appalachians as we get into the weekend, with cooler temperatures, more clouds, and an increasing chances for showers late in the period. Lingering, wrap- around showers will affect NE zones during the day Wednesday, with mostly dry weather elsewhere. Wednesday`s highs will range from the mid 70s in the NE mountains to the mid to upper 80s across the S half of the area. These temperatures will generally persist into Saturday, with highs on Sunday about 3 to 5 degrees cooler across most of the area. Overnight lows will range from the upper 50s in the NE to the mid 60s across the S through the period. /SEC && .AVIATION...
