234 FXUS62 KFFC 210518 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 118 AM EDT Sat Sep 21 2024 ...New 06Z Aviation Discussion... .SHORT TERM... (This evening through Saturday) Issued at 300 PM EDT Fri Sep 20 2024 Current cu field shown on satellite should stick around through the afternoon. Winds are currently mainly easterly but overall are variable and under 10 mph. The low pressure system has moved off the eastern coast to the Atlantic while the dome of high pressure continues to shift eastward. In between this low pressure and high pressure system a wedge has setup over the northeastern portion of the area which has allowed for temperatures to be slightly cooler in that area. Temps up to the upper 80s/low 90s are currently on track today except for the northeast GA mountains where temps should reach the low to mid 80s. The entire SE is in a dry pattern with this upper level pattern and thus dewpoints have been lowered a tad to account for this. RHs are expected to be in the 30% range for north Georgia especially. Tomorrow temps will be similar at 8-15 degrees above normal for much of the area. Hernandez && .LONG TERM... (Sunday morning through next Thursday) Issued at 300 PM EDT Fri Sep 20 2024 As the extended period begins, a strong upper level ridge will be extending from the Lower Mississippi River Valley towards the eastern Great Lakes region. The influence of this ridge and associated high pressure will keep weather conditions mostly dry through the early parts of next week. Furthermore, temperatures will run well above average for late September. Afternoon highs in the low 90s across the majority of the forecast area Sunday through Tuesday will be 6-13 degrees above daily normals. Aside from a stray, isolated shower here and there in the higher elevations of far northeast Georgia each afternoon, the ridge pattern will keep precipitation north of the forecast area as it continues to gradually move eastward towards the Atlantic Coast. By Tuesday a shortwave trough and surface low will swing through the Midwest, with a cold front advancing through the Tennessee Valley. At this point, showers and thunderstorm chances will begin to increase across north Georgia. Later next week there is still a lot of uncertainty with the potential for tropical development in the Caribbean/Gulf of Mexico. Most of the model guidance is in agreement that a broad low will develop in the western Gulf of Mexico, but there remain significant differences in location, timing, and intensity. There is also little run to run consistency in the guidance, at this time as well. Will continue to monitor over the next few days as guidance should come into better agreement. King && .AVIATION... (06Z TAFS) Issued at 1218 AM EDT Sat Sep 21 2024 VFR through the period. Winds will be light through the period. For the next few hours, direction should be mostly easterly with speeds of 4-5kt or less and then go VRB for the early morning hours. Once mixing begins, wind speeds should remain light but the direction should mostly be on the SW side. //ATL Confidence...06Z Update... High confidence all elements.
