$$What forecasters said that day
The local office's own words before this special weather statement 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 special weather statement went out at Jul 1, 2:54 PM EDT, 2 hours 53 minutes earlier.
Area forecast discussion, Jul 1, 2:54 PM EDT, 2 hours 53 minutes before
Area Forecast Discussion National Weather Service Peachtree City GA 254 PM EDT Sat Jul 1 2017 .SHORT TERM /Tonight through Sunday Night/... Convection has initiated across north and central Georgia this afternoon, and main concern continues to be potential for strong, damaging storms and heavy rain, generally in northwest Georgia through late evening. Hi-Res models still showing MCV will tap into destabilized, tropical air mass to promote storm development over the Tennessee Valley. Clusters of these storms are expected to move into northwest Georgia with the potential to produce very heavy rainfall and damaging winds. Already seeing some of this development between Nashville and Chattanooga, and have kept likely pops across northwest Georgia region through the afternoon. SPC has portions of north Georgia outlooked in a Slight Risk for severe storms. A Flash Flood Watch remains in effect through 10 PM due to the current wet soil conditions and the potential for storms to dump 1-2 inches of rainfall in a short period. The 3-hr FFG values continue to range in the 1.5-2 inch range for northwest Georgia, which could easily be achieved with slow moving or training storms, particularly in this tropical environment. PW on the morning sounding was 1.5 inches, but expect PWs to increase and approach 2 inches by this evening. Have continued with a slightly higher QPF than WPC's latest forecast for the 18-00z and 00-06z period. Broad upper trough axis remains over the eastern U.S. through the short term, and with a moisture-rich atmosphere fueled by flow around the surface high, expect slightly above normal diurnal precip chances into early week. Temperatures will remain warm, with highs in the upper 80s to low 90s. The combination of high relative humidity and warm temperatures will produce heat index values of 100- 103 degrees in portions of central Georgia. Those out enjoying the holiday weekend should stay hydrated and take breaks from the outdoors in cool or shady spaces. 31 .LONG TERM /Monday through Saturday/... Only tweaks to the long term based on the latest guidance. The July 4th holiday will feature a rather moist summertime airmass that will give potential for showers and thunderstorms... most so in the afternoon and evening. High Temps will range from the upper half of the 80s to the lower half of the 90s. Heat indices will range about 90 to 100. BDL PREVIOUS DISCUSSION... The long term begins with a broad upper trough over the eastern US just north of the CWA while a ridge of high pressure remains to our east. This keeps the CWA in on the periphery of both features. This will change very little over the long term keeping a moisture rich atmosphere over the CWA. A short wave will move into the upper trough toward the end of the long term which will sharpen the trough bringing the westerlies into the CWA pushing a cold front into the CWA late in the week. Scattered showers and thunderstorms will continue across the CWA each day through the long term mostly being diurnally driven. There should be an increase in convection ahead of the cold front at the end of the upcoming week. 17 && .AVIATION... 18Z Update... MVFR to VFR cigs remain over the area, and just now starting to see shower development over the area. Expect best -TSRA potential to be 21-01z, and have generally gone VCSH with TEMPO -TSRA. Winds should be west at 9kt or less through the period. Clearing skies overnight could result in patchy fog, particularly over north Georgia. PROB30 in again tomorrow from 19-23 for KATL. //ATL Confidence...18Z Update... Medium confidence on timing of TEMPO. High confidence on all other elements. 31 && .PRELIMINARY POINT TEMPS/POPS...

The area most likely to have severe storms is north of a line from Cedartown to Gainesville until around mid evening. Areas south of this line will be less likely to see severe storms. Also...some of the storms across extreme northwest Georgia could produce heavy rain. For more information see the latest Flash Flood Watch statement. .DAYS TWO THROUGH SEVEN...Sunday through Friday... There is a chance of thunderstorms each day, mainly during the afternoon and evening hours. A few storms could be strong with gusty winds as well as locally heavy rain which could cause temporary flooding of poor drainage areas. .SPOTTER INFORMATION STATEMENT... Spotter activation is not requested but spotters are encouraged to submit reports of severe weather and flooding through the web by going to weather.gov/atlanta.
