471 FXUS62 KFFC 190620 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 220 AM EDT Thu Sep 19 2024 ...New 06Z Aviation Discussion... .SHORT TERM... (This afternoon through Wednesday night) Issued at 229 PM EDT Wed Sep 18 2024 The upper low over the Carolinas will open up within the broader E Coast trough over the next 24 hours. The trough will shift slowly as the upper ridge from TX to the lower OH Valley builds. At the surface, a weak quasi-stationary front with several waves of low pressure along across the S portion of the County Warning Area (CWA) will sink S tonight. This front is firing off showers across the SE CWA. A few thunderstorms are possible in that area prior to sunset. Isolated showers are also occurring across the NE zones. A rumble of thunder is possible there as well, particularly in the mountains. Have adjusted cloud cover up for tonight over the NBM. However, clouds are expected to generally thin through the night, although some low clouds may thicken again toward daybreak across the NE. A few showers are possible once again Thu afternoon in the NE mountains. However, shower activity associated with the aforementioned front should shift S of the area by then. Low temperatures tonight will range from the mid 50s in the NE mountains to the upper 60s in the extreme SE. With less cloud cover expected on Thu, high temperatures are expected to range from the mid to upper 80s across most of the area, with some 70s in the NE mountains. Low temperatures Thu night will be similar to tonight`s. SEC && .LONG TERM... (Thursday through next Tuesday) Issued at 229 PM EDT Wed Sep 18 2024 Key Messages: - A small mention of rain around mid-week next week, otherwise, dry conditions in the long term - Temperatures will warm up through the weekend Still a good bit uncertainty for the long term weather pattern with this forecast update. The most notable change compared to the previous forecast was slightly warmer daytime highs this weekend (+/- 2-4 degrees). This is owing to the departure of a surface low up the East Coast and how quickly a surface high can take up residence across the northeast. Again, there is still disparity among latest ensemble (EPS/GEFS) runs with the features mentioned above. Elected to not deviate too much from the previous forecast and still reflects the scenario of the `delayed` onset of a wedge set up across the northeast -- with forecast high temperatures in the upper 80s to low 90s through the weekend. Once the wedge does settle into the region, temperatures will cool off a bit. Rain could make a brief return late next week but overall chances remain quite low. 07 && .AVIATION...
