826 FXUS62 KFFC 141104 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 704 AM EDT Mon Apr 14 2025 ...New 12Z Aviation Discussion... .SHORT TERM... (Today through Tuesday) Issued at 353 AM EDT Mon Apr 14 2025 Key messages: - Warmer temperatures today. - Light showers across the N tonight. - Cooler temperatures on Tuesday. Mostly sunny skies are expected again today, although clouds will begin to filter into NW GA late in the afternoon. Temperatures will continue to warm, with highs ranging from the mid 70s in the NE mountains to the lower to mid 80s elsewhere. These temperatures will be around 10 degrees above normal in N GA and about 5 to 7 degrees above normal across central GA. SW winds will pick up a bit, with gusts over 20 mph in N GA during the afternoon. A weak cold front will approach the area from the NW this evening, with isolated to low end scattered showers moving into the County Warning Area (CWA) before weakening. Rainfall amounts are expected to average less than a tenth of an inch N of the Atlanta metro area. Some trace amounts are possible a bit farther S. MUCAPE (instability) will be very low (mostly less than 100 J/kg). Additionally, there will be CIN in place, and daytime heating will be gone by the time showers move in. As a result, although the chance of thunder is non- zero, it`s not enough to mention in the forecast. The biggest impact of the cold front will be to knock temperatures back down to near or slightly below normal. After lows tonight mostly in the 50s, daytime highs on Tuesday will range from the upper 50s in the NE to near 80 in the extreme SE. Minimum relative humidity values will range from 22 to 30 percent this afternoon, with the lowest values generally SE of Macon. Fuels will be dry, so humidities will need to be monitored for a possible short fuse Fire Danger Statement. However, duration and areal coverage of sub-criteria humidity precludes issuance at this time. Breezy NW winds are expected Tuesday, with gusts of 20 to 30 mph. Wind gusts near 35 mph will be possible in the higher elevations in N GA. Minimum relative humidity values are forecast to drop below 25 percent across most of the area, and fire wx products will likely be required. /SEC && .LONG TERM... (Tuesday night through Sunday) Issued at 353 AM EDT Mon Apr 14 2025 Key messages: - Warm and mostly dry through the weekend. Surface high pressure and northwest flow will return and dominate the weather pattern Tuesday Night through the end of the week. A midlevel ridge situated over the Central CONUS, will begin shifting eastward becoming more amplified as a low develops and deepens over the western CONUS by the weekend. Additionally, the surface high center will move off the East Coast. Latest ensembles continue to remain on the drier side with this next system though there is still some variation in timing/strength of it. Though as it stands, any notable rain chances look to hold off until next week. Thus, warm and dry conditions will prevail across North and Central Georgia through Sunday. Fire weather conditions will likely need to be monitored across the forecast area through the end of the work week given continued warm and dry conditions. Temperatures also trend warmer through the end of the period as ridging becomes amplified over the southeast through the week. Forecast highs start off in the low 60s to mid 70s (Wednesday) climbing into the mid to upper 80s -- flirting with low 90s in Central GA -- by Friday and through the weekend. 07 && .AVIATION...
