$$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 15, 3:43 PM EDT, 3 hours 23 minutes earlier.
Area forecast discussion, Jul 15, 3:43 PM EDT, 3 hours 23 minutes before
Area Forecast Discussion National Weather Service Peachtree City GA 343 PM EDT Sun Jul 15 2018 .SHORT TERM /Tonight through Monday Night/... The upper ridge continues over the forecast area today with a very moist airmass in place. PW values range around two inches. Mostly diurnal convection being driven mainly by old boundaries and also what appears to be a weak low over north GA. Thunderstorms developing over TN and KY and moving southeast into north GA may affect that area into the overnight hours. High res models hint that there may be continued development of convective complexes during the night that drift southeast. However...upper winds are weak so if convection develops in TN...the drift toward north GA could be a slow one. In general...northwest GA should be watched for slow moving storms. The upper ridge gets suppressed a bit on Monday and a weak trough forms over the OH and TN valley areas. This combined with the deep moisture could support more coverage of showers and thunderstorms tomorrow. Likely pops still look okay for that time. Expect no big changes in temperatures. 41 .LONG TERM /Tuesday through Sunday/... Only gradual changes in the large scale pattern in the long term period. Large broad ridge over the western and central CONUS on Tuesday progged to remain over the western CONUS while slowly amplify. Troughing over the Great Lakes and midwest progged to deepen which puts southeast states in increasingly stronger NW flow and slightly drier air, more so perhaps in north GA, by the end of the week. Could be a pattern in which we see increased overnight and next day MCS activity like we saw a few weeks ago, but too soon to pin that down. Until then, coverage and timing of convection and min/max temps should remain nearly the same until mid week with some slightly lower PoPs mid week on. PW values also should drop some so risk of flooding should subside a little. Heat indices should remain 95 to 102 through the extended though will continue to monitor. Tropical activity not seen in model progs or NHC outlooks. SNELSON && Previous LONG TERM... /Monday Night through Saturday/... /Issued 338 AM EDT Sun Jul 15 2018/ Medium-range model trends continue to be consistent and in fairly good agreement through the majority of the Long-Term Forecast period. Relatively high-amplitude upper pattern persists with the eastern U.S. under a deepening upper trough. Sharp frontal boundary sags into the forecast area midweek, lingering over the region through the latter half of the week before washing out. Some drier air does try to fill into the north Wednesday/Thursday behind the front, but not enough to eliminate POPs altogether across the north just yet. High POPs and seasonal temperatures are expected through the Extended Forecast period. 20 AVIATION... 18Z Update... Cumulus field in the 3500-4500 ft range this afternoon and again showers/storms with greatest chance 18-00z. Winds light southeast this afternoon...but may swing to the southwest temporarily. KATL should swing southwest after 00z tonight with some lowering cigs to ifr for tomorrow morning. //ATL Confidence...18Z Update...
