FXUS62 KFFC 041835 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 235 PM EDT Tue Aug 4 2026 ...Afternoon Area Forecast Discussion... .KEY MESSAGES... - Scattered showers and thunderstorms are possible this afternoon. High rainfall rates and slow storm motions will support localized flash flooding concerns. - 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... (This afternoon through Wednesday) Issued at 234 PM EDT Tue Aug 4 2026 A mid-level closed low has taken up residence very nearly atop the state of Georgia, seen plainly on visible satellite imagery where ongoing convection swirls counter-clockwise. Precipitable water is largely seasonable (~1.7"), but very weak steering flow and near- negligible surface winds in the center of the low pressure system have supported slow to effectively stationary storm motions. Rainfall rates of 1-2" hour (and occasionally as high as 2.5" an hour) have been observed through the afternoon, enough to support continued isolated flash flooding concerns, especially in urbanized locations/areas with high concentrations of impervious surfaces. Convection kicked off over the Atlanta metro earlier this morning, and any subsequent redevelopment will allow for quick responses. Severe concerns remain minimal and isolated at best in the absence of meaningful kinematics, with the most likely scenario for an errant severe storm being an especially water-loaded downdraft. Convection will taper off later this evening -- generally following the diurnal cycle -- giving way to chances for patchy dense fog in the morning for locations that received heavy rainfall during the afternoon. The pattern remains largely unchanged tomorrow aside from the aforementioned low pressure system beginning to weaken, supporting yet another day of diurnally-enhanced showers and thunderstorms capable of producing isolated instances of flash flooding/flooding of creeks and streams. Highs will remain in the mid-80s to lower 90s through tomorrow, with overnight lows in the upper 60s to lower 70s. && .LONG TERM... (Thursday morning through next Monday) Issued at 234 PM EDT Tue Aug 4 2026 Models are in good agreement that the mid-level low that has been parked over our CWA for the last few days will finally begin to dissolve as it shifts off toward the northeast through Wednesday. Our area will remain in a moist southwest flow along the periphery of a strengthening Bermuda high pressure. This will reinforce the continuation of a summertime pattern with decent PWATs ranging from 1.5-2.0" and diurnal thunderstorm chances each day through the period. The coverage of thunderstorms will be scattered to numerous through the period with plenty of instability over the region. In addition, ample afternoon cloud cover will suppress high temperatures by a few degrees through Friday before higher heights build by late week, allowing for temperatures to climb into the upper 80s to low 90s as the high builds in closer to our area. While no organized severe weather is expected, a few storms may become strong with gusty winds as the primary threat, in addition to localized flash flooding in areas with prolonged convective activity. && .AVIATION...
