060 FXUS62 KFFC 201120 AAA AFDFFC Area Forecast Discussion...Updated National Weather Service Peachtree City GA 620 AM EST Wed Nov 20 2019 ...12Z Aviation Forecast Discussion... .SHORT TERM /Today through Thursday/... Dry and mild through the short-term forecast period as the upper pattern transitions from northwesterly flow to a broad, flat ridge and surface high pressure prevails. Cold front approaches late in the day Thursday, but remains far enough west of the state to keep rain chances out of the area. 20 .LONG TERM /Thursday Night through Tuesday/... Changes will be underway at the beginning of the long-term forecast period as high pressure will begin to give way to the next incoming system. Surface high pressure will shift off the Atlantic coast on Friday as a cold front initially makes southward progress into the Tennessee Valley. This will serve to increase cloud cover and shower chances initially across far north Georgia through the day Friday. Temperatures Friday will again be several degrees above normal in advance of the front despite increasing clouds. By late Friday, an upper low tracking through the Central Plains will initiate the development of a surface low along the cold front in the Arklatex region. The surface low will track northeastward toward the Ohio Valley Friday night into Saturday, pushing the cold front eastward across the forecast area. Widespread shower activity will thus overspread the area through the day Saturday. With continued limited forecast instability, the threat for any thunderstorm activity continues to appear negligible. Rain will gradually clear from west to east from Saturday evening into Sunday morning behind the cold front. The healthiest rainfall totals will be generally north of I-20 where amounts at and above one inch are most likely with isolated amounts over 1.5" possible in the mountains. Sunday will bring clearing skies and noticeably cooler temperatures, ranging 3-8 degrees below normal. Dry high pressure and seasonal temperatures will hold into Monday. Models begin to diverge more significantly by Tuesday regarding the handling of the next system. At this time, will continue to gradually increase PoPs beginning Tuesday.
