515 FXUS62 KFFC 251847 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 247 PM EDT Thu Oct 25 2018 .SHORT TERM /Tonight through Friday Night/... The remnants of Willa have formed into a surface low pressure that is currently positioned along the Louisiana Gulf Coast, and is continuing to move northeastward towards our area. Meanwhile, a trough positioned over the midwest is shifting towards the Ohio Valley. As the surface low moves across the Gulf Coast today, it will amplify that trough to the north. Furthermore, surface high pressure moving over the mid-Atlantic states will lead to high pressure wedging in from the northeast by this evening. As increased moisture spreads into north and central Georgia this afternoon and evening ahead of the approaching area of low pressure, clouds will gradually lower throughout the afternoon from southwest to northeast. After 00Z, ceilings will continue to lower into the MVFR/IFR range. Rain will begin to move eastward into the area during the late afternoon hours. Instability values during the late afternoon are sufficient to produce some isolated thunderstorms through the early evening. As rain begins to fall through the wedge, that feature will continue to strengthen. LIFR/IFR ceilings along with some patchy fog are expected to be solidly in place by Friday morning, and the low ceilings will remain in place throughout the day on Friday. Temperatures will be limited within the wedge on Friday, with highs only reaching into the low to mid 50s throughout most of north Georgia, along with only mid to upper 40s in the northeastern mountains. King .LONG TERM /Saturday through Thursday/... Low pressure/remnants of Willa should be moving off the coast of the Middle Atlantic at the beginning of the long term portion of the forecast. Wrap around/upslope precip is likely on the west side of the low, so low end pops will continue into Saturday for areas mainly along and north of the I-85 corridor. A cold front will approach from the north later on Sunday and move through the CWFA on Monday. Not much moisture associated with this boundary, especially south of Interstate 20. The highest pops should be across the northern CWFA. High pressure will dominate the weather through the middle of the week. A sharp/strong cold front looks to impact the CWFA by the end of the week.
