314 FXUS62 KFFC 041422 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 1022 AM EDT Mon Aug 4 2025 ...Morning Update... .UPDATE... Issued at 1007 AM EDT Mon Aug 4 2025 A blanket of low clouds and increasing shower activity is the theme for this Morning morning as a wedge remains firmly in place. Aided by isentropic lift and increasing moisture shower activity has begun to increase from south to north. With limited instability, thunder activity remains confined to the Florida Panhandle and far southern Georgia at this time. However, isolated thunderstorms will remain a possibility as we head into the afternoon and evening. Over the past 24-hr rainfall totals of 1.5 to 3.5 inches were observed over much of Central Georgia. Isolated higher totals up to 4 inches were also observed. Right now, 1-hr MRMS estimates of 0.50 to 0.80 inches at most with this with heavier activity moving through parts of Central Georgia (just north of Macon). Though rainfall rates are expected to increase over the course of the day and given antecedent conditions, flash flooding and river/stream/creek responses will be things to monitor. The Flood Watch will likely be expanded eastward later this afternoon as latest hi-res guidance paints some of the higher rainfall activity setting up across areas along and east of the I-85 corridor. && .SHORT TERM... (Today through Tuesday) Issued at 409 AM EDT Mon Aug 4 2025 Key Messages: - A Flood Watch is in effect through this evening for the western two-thirds of the area including the Atlanta Metro and Macon. - Additional rainfall totals of 2 to 4 inches with isolated higher amounts remain possible through Tuesday within the watch area. - `Cool` below normal temperatures will stick around through Tuesday with forecast high temperatures mainly in the 60s and 70s. Current radar loop shows scattered lite showers and drizzle across north and central GA. We are still under the influence of the wedge of high pressure that continues to build SW down the eastern seaboard. This wedge is keeping things very stable across the CWA as we have not seen much in the way of thunder over the past few days. This wedge is expected to continue to dominate the weather pattern into the long term forecast periods keeping north and central GA in a moist/stable environment. The stationary front that has been stalled over south GA will begin to push back northward bringing deep moisture with it. This moisture is almost tropical like as PWs stay in the 1.5" to 2.5" range through the short term. Current QPF amounts are 1-2 inches Today and Tue across the area. Things tapper off on expected precipitation totals Wed but this still gives us a 3 day total of 2-4 inches with isolated higher amounts. The higher amounts are still mainly across central GA but they are creeping a bit north with the boundary. WPC has placed the majority of our CWA under a Slight risk area for flooding and we have continued with the flood watch across most of our CWA as well. Temps will continue to be below seasonal norms with highs Today and Tues mainly in the 60s and 70s with some 80s across our southern CWA. 01 && .LONG TERM... (Tuesday night through Sunday) Issued at 409 AM EDT Mon Aug 4 2025 Key Messages: - Flooding issues potentially linger through mid-week, with daily showers and storms continuing into the weekend. - Cooler than normal temperatures mid-week, returning to near normal late week and over the weekend. The wet conditions and flooding concerns from the start of the week will linger through Wednesday. The driving force behind this will continue to be the combination of a mid-level trough extending down over the region from the Great Lakes, and a frontal boundary sitting over the southern half of Georgia. Large scale ascent from the nearby trough combined with plentiful moisture (PWAT values over 2") in mid-level S/SW flow will support widespread showers and thunderstorms during the day Wednesday. With several days of rainfall leading up to this, both flash flooding and river/creek/stream flooding are possible. Thankfully, conditions will slightly dry for the end of the week and over the weekend as the trough axis centers shifts a bit east and stalls out, centering over Georgia. PWAT values will fall to around 1.5-1.75", supporting more of our typical diurnally driven isolated-scattered showers and storms for this time of year. Severe weather and flooding threats will be low (but non- zero) during this period. Temperatures during the long term period will start off cooler than normal with the lingering wedge, but will gradually warm back up to near normal by the weekend. Culver && .AVIATION... (12Z TAFS) Issued at 613 AM EDT Mon Aug 4 2025 Isolated showers and drizzle across the area this morning with increasing precipitation this afternoon/evening. Expecting mainly IFR ceilings with brief periods of MVFR through the period. East winds in the 6-12kt range with higher afternoon gust will also continue. VSBYs will be in the VFR to MVFR range. //ATL Confidence...12Z Update... Confidence high on all elements. 01 && .PRELIMINARY POINT TEMPS/POPS...
