$$What forecasters said that day
The local office's own words before this flash flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Atlanta, GA wrote its last area forecast discussion before this flash flood warning went out at Sep 11, 3:05 PM EDT, 3 hours 37 minutes earlier. Its key messages:
- Scattered to numerous showers and thunderstorms are expected both this afternoon and on Saturday. An isolated damaging wind gust threat remains possible through this evening for areas north of Interstate 20.
- Hot and humid conditions stick around between Sunday through mid-week, while rain chances remain limited (< 20% chance).
- Slightly above normal temperatures continue through this weekend with heat index values returning to the low 90s and low 100s.

Area Forecast Discussion National Weather Service Peachtree City GA 305 PM EDT Fri Sep 11 2026 ...Afternoon Area Forecast Discussion... .KEY MESSAGES... - Scattered to numerous showers and thunderstorms are expected both this afternoon and on Saturday. An isolated damaging wind gust threat remains possible through this evening for areas north of Interstate 20. - Hot and humid conditions stick around between Sunday through mid-week, while rain chances remain limited (< 20% chance). - Slightly above normal temperatures continue through this weekend with heat index values returning to the low 90s and low 100s. && .SHORT TERM... (This afternoon through Saturday) Issued at 255 PM EDT Fri Sep 11 2026 Showers and thunderstorms were quick to develop today with activity starting to fire as early as 12PM. The initial push of precipitation is currently moving through Columbus with additional convection developing as far north as I-20 where a differential heating boundary has set up. Per the 12z FFC sounding, PWs are sitting right at 1.87" which is above the 90th percentile climatologically. Thus, showers and thunderstorms will be efficient rain producers and could drop a quick 1-2" in a short amount of time lending to a non-zero chance of localized flash flooding in the typical spots. Frequent lightning and gusty winds (up to 40 MPH) will accompany all storms. Sufficient instability will make up for lack of shear overall and lend to an isolated damaging wind gust threat across North Georgia (along/north of I-20) through this evening. A secondary push of precipitation is still being highlighted by some of the hi-res guidance moving into western Georgia after 3-4 AM in association with a weak surface low. Patchy fog and low clouds are also likely to be around early Saturday as moisture remains high and winds remain light. However, coverage of fog will be highly dependent on any lingering showers and storms which could inhibit development and extent. Otherwise, a rinse and repeat forecast (literally) can be expected for North and Central GA Saturday. Scattered to numerous showers and storms peaking during the afternoon and potentially lingering after the sun goes down. && .LONG TERM... (Sunday morning through next Thursday) Issued at 255 PM EDT Fri Sep 11 2026 By Sunday morning the main frontal boundary from the short term will have moved into central GA with a slightly drier airmass moving into North GA. Deep moisture from the Gulf will remain in place across central and south GA with diurnally driven storms expected. This frontal boundary continue to move south clearing the area by Mon morning. The drier airmass remain across the area through the middle of next week keeping precipitation chances at 20% or less each day (Mon-Thu). Temps will stay in the upper 80s to middle 90s through day 7 but with the drier airmass moving in Heat index values will slowly fall through the middle of next week. Dewpoints Sunday and Mon will be in the lower to middle 70s but they will fall into the lower to middle 60s by Wed. Even with temps still in the lower 90s it will feel a bit more comfortable. && .AVIATION... (18Z TAFS) Issued at 131 PM EDT Fri Sep 11 2026 Mostly VFR to start with conds likely to deteriorate after 06z. Sct to BKN cigs 2.5-5kft with -shra/vcsh prevailing for the better part of the afternoon (18-02z) for all sites. Still a good chance for greater coverage of IFR btwn 08-14z with iso to sct shra and MVFR vsbys in BR. Big question for overnight is if any shra activity limits IFR (and lower) cig coverage. Anticipating at least MVFR but patchy IFR is on the table. Near due S wind, favoring SSW at 4-8kts outside of any convection. //ATL Confidence...18Z Update... Medium confidence on all elements. 07 && .PRELIMINARY POINT TEMPS/POPS...
