FXUS62 KFFC 041729 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 129 PM EDT Tue Aug 4 2026 ...New 18Z Aviation Discussion... .KEY MESSAGES... - Scattered showers and thunderstorms are possible this afternoon. - Diurnally-enhanced storm chances will continue through the end of the week. - Afternoon highs will remain within a degree or two of seasonal norms (mid-80s to lower 90s) through the week. && .SHORT TERM... (Today through Wednesday) Issued at 302 AM EDT Tue Aug 4 2026 While the mid level cut-off low spins down overhead, conditions will be fairly rinse and repeat through mid-week. Weak and broad upper level forcing combined with diurnal heating will lead to scattered showers and a few rumbles of thunder each afternoon. No widespread severe is expected at this time, though a few storms could develop gusty winds and locally heavy rainfall. PWATs have come down from this last weekend's highs (from 2-2.2" down to 1.6-1.8"), so the risk of flooding will be fairly low outside of any stubborn cells that don't move. One interesting feature to watch today will be storm motion, as the low overhead turns the scattered showers/storms around a central point likely over or near metro Atlanta (this won't impact much in the forecast, just something cool to see later today on satellite/radar). Highs will continue to hold below 90 through the next few days. Or as long as the upper level low stays overhead. Shower and thunderstorm coverage will help to moderate temps during the day before clearing out for radiative cooling at night. && .LONG TERM... (Wednesday night through Monday) Issued at 302 AM EDT Tue Aug 4 2026 Warm and Humid with Daily Storm Chances: Overall, North and Central Georgia will remain in moist southwest flow through most of the long term period. The mid-level low parked over the TN Valley will finally slide north Thursday as it gets squeezed between a ridge pushing in from the Western Atlantic, and broad troughing across the Central US. Coverage of showers and storms will be scattered to numerous through Friday, with plenty of moisture and instability remaining over the region. While no widespread severe weather is expected, a few strong storms will be possible during the period, with strong winds as the primary threat, in addition to localized flash flooding from the high moisture content. Model guidance remains in good agreement on this typical summertime pattern persisting through the upcoming weekend into early next week. High temperatures will gradually warm up to the low to mid 90s by this weekend as the ridge builds further over the region. Heat index values will rise to the upper 90s to 100 across North GA, with low 100s across Central GA. && .AVIATION...
