The National Weather Service in Peachtree City has issued a * Flash Flood Watch for the majority of north and central Georgia, except for far northwest Georgia and southeast central Georgia. * From Wednesday afternoon through Friday morning * Periods of heavy rainfall are expected across the area with the outer rain bands of Hurricane Sally as it tracks inland west of the area Wednesday and Thursday, then weakening as a tropical depression by the time it tracks across the central portion of the area into early Friday. Associated rainfall totals in excess of 3 to 4 inches and areas of 5 to 6 inches are expected with even locally higher amounts possible. The highest amounts look to be in a swath centered along the I-85 corridor, though this could shift with future forecast updates. * Soils are expected to become quickly saturated and runoff from heavy rain will lead to a threat of flash flooding. Some of the rivers, small creeks, and streams could also respond with flooding that may linger beyond the watch period. PRECAUTIONARY/PREPAREDNESS ACTIONS... A Flash Flood Watch means that conditions may develop that lead to Flash Flooding. Flash Flooding is a very dangerous situation. You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued. && $$

What forecasters said that day
The local office's own words before this flash flood watch 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 watch went out at Sep 15, 12:22 PM EDT, 3 hours 2 minutes earlier.
Area forecast discussion, Sep 15, 12:22 PM EDT, 3 hours 2 minutes before
Area Forecast Discussion National Weather Service Peachtree City GA 1222 PM EDT Tue Sep 15 2020 .UPDATE... Little changes to near term trends as fcst largely on track with wedge building in from the NE and continued stratus deck over much of the area (sans the far north). Axis of showers and associated pops should shift farther south this afternoon into primarily central GA though isolated development could linger in parts of the north. Main focus still on the heavy rain and flooding threat beginning late Wed with Sally tracking inland to our west. Will likely have a Flash Flood Watch issued with this main afternoon package. Previous discussion follows... Baker && .PREV DISCUSSION... /Issued 739 AM EDT Tue Sep 15 2020/ PREV DISCUSSION... /Issued 427 AM EDT Tue Sep 15 2020/ SHORT TERM /Today through Wednesday/... Current satellite loop shows Hurricane Sally due south of Mobile Bay. The latest forecast shows it slowly moving northward making landfall near the MS/AL border around daybreak Wed morning. There is also a weak cold front oriented from NW to SE across north and portions of central GA this morning. This front is acting as a catalyst for some weak showers that have been fairly steady this morning. They appear to be growing so will continue with a chance of showers this morning. The front is expected to push a bit further south today before being pushed back northward Wed as Sally moves to the NE into the extended. With Sally pushing onshore in the the next 24 hours moisture will steadily increase across north and central Georgia. Precipitable water values are currently in the 1.6 to 1.8 in range and will increase to 2" through Wed. As Sally near the state. a high pressure ridge nosing down the Eastern seaboard helps keep more stable conditions in place over the area. Looks like the heaviest precip from Sally will begin to push into western portions of the state Wed night and continue into the extended forecast periods. With increasing precip chances temps today will get up into the upper 70s and lower 80s. Temps Wed will stay mainly in the 70s. 01 && .LONG TERM /Wednesday Night through Monday/... The main concern for the long term continues to be the effects of Sally on the forecast area. The Official forecast from the NHC takes Sally across roughly central GA Thursday night and Friday as a tropical depression. Heavy rain potential starts to ramp up Wednesday night and will continue through Thursday for much of N and portions of central GA. Heavy rainfall potential could continue Thursday night into Friday for portions of north and east GA. Along with the heavy rain potential, you can't rule out the possibility for isolated tornadoes over the far SW CWA Wednesday Night from about CSG to MCN and S. Once the remains of Sally passes the area later Friday, a cold front is expected to move south over the area Friday night and early Saturday. This will diminish rain chances Friday night into Sunday. The European and GFS are not in very good agreement here and that will just have to be adjusted with time. BDL && HYDROLOGY... Potential rainfall from Sally could range 3 to 8 inches with locally higher amounts centered roughly along the I-85 and I-20 corridors, with slightly less amounts over the far NW counties and the counties S and E of MCN. This could lead to Flash flooding or river flooding for many areas and a flash flood watch will likely be issued later today. Please note that any shift of Sally's track will shift the axis of heavy rain as well. && .AVIATION... 12Z Update... A few showers lingering along the weakening frontal boundary lingering east to west across the area. Will see mainly MVFR to IFR ceilings across the area today with SHRA slowly increasing and moving southward with the frontal boundary. Winds will stay out of the East with speeds starting in the 6-12kt range increasing into the 12-15kt range with gust to 20kt by 14z. Wind speeds will stay elevated through the period with precip chances increasing through Wed morning. //ATL Confidence...12Z Update... Confidence medium to high on all elements. 01 && .PRELIMINARY POINT TEMPS/POPS...
