948 FXUS62 KFFC 141950 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 250 PM EST Thu Nov 14 2024 ...Afternoon Area Forecast Discussion... .SHORT TERM... (This afternoon through Friday) Issued at 233 PM EST Thu Nov 14 2024 Surface analysis shows a cold front across far NW GA with a wedge still in place across far NE GA. The front will continue to push southward this afternoon, eventually mixing out any remains of the wedge. High pressure, cooler temperatures and dry conditions will build in behind the exiting frontal boundary. Temps for Friday will be near normal values. Patchy light rain will continue ahead of the front across the far SE portion of the CWA for the next few hours. QPF amounts will be light and generally average around a tenth of an inch. Some patchy fog is possible, but winds speeds should keep widespread and/or dense fog at bay. NListemaa && .LONG TERM... (Saturday morning through next Wednesday) Issued at 233 PM EST Thu Nov 14 2024 The extended starts out dry and cool with lows Sat morning in the 30s and 40s across the area. High pressure which began to build into the area from the short term strengthens through the weekend becoming centered over the Carolinas and N GA by Sun morning. This ridge will keep things dry but we will see a slight warming trend beginning Sunday afternoon through Tues. We will begin to see a pattern change Monday night into Tuesday as the high pressure ridge shifts eastward becoming centered just off the GA coast by 12z Tue. A cutoff low begins to develop along the MX/TX/NM border Sunday morning then moves rapidly NE into the central/northern plains by Monday afternoon. There is still some uncertainty with respect to the intensity of the low and how it will impact Georgia, especially as it gets absorbed by a deep trough digging into the central CONUS. However, guidance is trending towards better agreement on a cold front extending from this low advancing towards the Lower Mississippi River Valley by Tuesday morning. Precip chances increase from west to east for GA beginning Tue afternoon/evening as this boundary moves into the region. Meanwhile, a tropical cyclone is anticipate to be positioned to the west of the Yucatan Peninsula early Tuesday, then advance east/northeast through the Gulf of Mexico. Due to the ridge over the Atlantic coast/west Atlantic blocking northward progression and the cold front (and aforementioned trough) pushing any potential tropical cyclone south and east of GA. The models continue to track any tropical cyclone activity through the Florida Peninsula Wed/Thu. 01 && .AVIATION...
