FXUS62 KFFC 181710 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 110 PM EDT Mon May 18 2026 ...New 18Z Aviation Discussion... .KEY MESSAGES... - Dry conditions through Tuesday outside of a few afternoon showers and storms and along the GA/AL border. - Warm temperatures continue the next few days with highs in the upper 80s to low 90s. - Increased rain chances return from Wednesday through the weekend. && .SHORT TERM... (Today through Tuesday) Issued at 500 AM EDT Mon May 18 2026 Another warm day expected this afternoon as temperatures rise into the upper 80s and low 90s. The best chance for afternoon thunderstorms has shifted to the west, though a few isolated thunderstorms are possible along the GA/AL border this afternoon. Coverage seems to be significantly less than yesterdays storms. Instability will be a limiting factor as well with high pressure keeping a cap on most of the CWA. The forecast for Tuesday is a bit of a carbon copy for today though with increasing afternoon clouds out a head of the cold front that's expected to bring the next round of weather. You can find more information about that system in the long term below. Winds will remain southerly at 5-10mph with some higher gusts in the higher elevations of northern Georgia. Overnight lows will be pleasantly in the mid 60s. && .LONG TERM... (Tuesday night through Sunday) Issued at 500 AM EDT Mon May 18 2026 By Wednesday afternoon and evening, a cold front will push southeastward toward far north Georgia. The highest PoPs will be relegated to these areas in proximity to the frontal forcing with drier conditions initially favored farther southeast. The front makes only limited southward progress by Thursday into north Georgia as upper support departs northeastward from the Great Lakes into Quebec. As such, diurnally-enhanced PoPs should again be highest along/north of the I-20 corridor. Flow aloft then transitions into southwest flow by late week as the front becomes stationary. Weak shortwaves within this flow will enhance convective coverage headed into the weekend, particularly with the aid of diurnal heating. Coverage again will likely be highest across roughly the northern half of the area through this period. The organized severe threat continues to look low given the summer-like weakly sheared environment, a couple of strong to isolated severe storms certainly can't be ruled out. While locally heavy rainfall will also be possible, the lack of a widespread and persistent soaking rainfall will limit the overall impact on the drought through the forecast period. Temperatures remain generally several degrees above normal (highs in the mid to upper 80s to lower 90s on the warmest days and lows in the 60s), though marginally cooler highs are possible late week given increased clouds and convective coverage. && .AVIATION... (18Z TAFS) Issued at 1251 PM EDT Mon May 18 2026 VFR conditions will prevail at most sites through the 18Z TAF period.

Skies mostly SKC tonight into Tuesday AM, with a low chance for MVFR-IFR CIG development at MCN/AHN around 10-14Z.
