FXUS62 KFFC 190949 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 549 AM EDT Tue May 19 2026 ...New 06Z Aviation Discussion... .KEY MESSAGES... - Warm temperatures continue through the work week with highs in the upper 80s to low 90s. - Increased rain chances return tomorrow through the weekend, especially in northern and western Georgia. && .SHORT TERM... (Today through Wednesday) Issued at 455 AM EDT Tue May 19 2026 Temperatures will quickly climb into the upper 80s and low 90s this afternoon, with relative humidity falling into the upper 30% range as high pressure keeps moisture off to the west of the CWA. This will prevent afternoon thunderstorms for a final day before we reintroduce them to the forecast tomorrow. Winds will be light out of the S/SE at less than 10mph. Overnight lows will remain in the 60s and moisture values across NW Georgia will increase out ahead of a cold front pushing through the TN river valley area. As a result, the best chance for thunderstorms will be limited to the far northwest tomorrow during the afternoon and early evening. While a few rumbles of thunder are possible, widespread severe weather appears unlikely in this dry environment. && .LONG TERM... (Wednesday night through Monday) Issued at 455 AM EDT Tue May 19 2026 A weakening cold front will have entered the far northern tier by the time the long term period picks up on Wednesday evening. Scattered showers and isolated thunderstorms will linger across far north and west Georgia in the closest vicinity to the front, though coverage will steadily diminish after sunset and thunderstorms will come to an end after midnight. As ridging over the Atlantic Coast and west Atlantic continues to flatten, the front will make some minimal progress southward during the early morning, eventually stalling north of I-20 amid southwesterly flow aloft during the daytime on Thursday. Temperatures and dewpoints will start the morning on Thursday in the mid to upper 60s across the area. High temperatures will be slightly cooler across far north Georgia (in the low to mid 80s) behind the front compared to upper 80s elsewhere in north Georgia and low 90s in central Georgia. Hot and humid conditions will support diurnally enhanced convection, with PoPs of 60-80% in the northern half of the area closest to the frontal boundary, and 30-50% in the southern half of the area. The front will become less defined and begin to lift back northward on Friday within southwest mid-level flow along the western periphery of the Atlantic ridge. This southwesterly flow will intensify as a second ridge approaches from the Great Plains, giving the front an additional push away to the north. While this ridge sets up over the eastern CONUS during the weekend, the aforementioned southwesterly flow will continue to spread ample moisture into the forecast area. Temperatures rising into the 80s and low 90s each day along with ample moisture will lead to scattered to numerous diurnal convection each day through the weekend into early next week. Coverage of storms will be greatest during the afternoon and evening. At this time, the deepest moisture and highest PWATs will keep the most consistent heavy rainfall west of Georgia. && .AVIATION... (12Z TAFS) Issued at 546 AM EDT Tue May 19 2026 VFR expected through the day. A CU field will develop after 16Z bringing a SCT low VFR deck, with mostly clear skies returning after 00Z. Winds will be out of the SE at 5kts or less. //ATL Confidence...06Z Update... High on all elements. Vaughn && .PRELIMINARY POINT TEMPS/POPS...
