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 3, 3:27 PM EDT, 3 hours 59 minutes earlier.
Area forecast discussion, Jul 3, 3:27 PM EDT, 3 hours 59 minutes before
Area Forecast Discussion National Weather Service Peachtree City GA 327 PM EDT Mon Jul 3 2017 Although we have weak zonal flow aloft, there are pieces of energy that will pass over a portion of the region through the short term. These pieces of energy/impulses are from a nearly stationary trough across the central CONUS. The timing of these waves will correspond with the convection we observe, mainly across far north GA. As an impulse exits to our northeast this afternoon, we will continue to see scattered showers and thunderstorms in eastern GA. Meanwhile, across west/central GA, we are under a bit of subsidence which is helping to suppress any precipitation activity. Feel much of the precipitation coverage will dwindle as we approach the evening hours with the subsidence slowly working eastward. Activity across NE Mississippi will march east across northern Alabama through the late afternoon. If this activity can hold together (which is associated with another impulse aloft), then parts of the NW tier of GA may see thunderstorms by this evening. However, given loss of heating and upper level dynamics, do not anticipate this precipitation to hold together too long. Residual showers and thunderstorms are possible across the north tonight, but coverage should be very limited. Fourth of July: Should be a fairly nice day overall. May begin with some patchy fog, but this should mix out after sunrise. With the next impulse passing to the north of the region through the day, current thinking is that we will see most of the shower/thunderstorm activity across far north GA. A few of these storms could become severe. However, the coverage and intensity are truly in question for our region given the dynamics may be too far to the north. There looks to be marginal BKN shear and CAPE values around 1500 J/kg. So we can not rule anything out. The main threats will be gusty winds, large hail, frequent lightning and heavy rainfall. As for the rest of the region, anticipate a chance of afternoon thunderstorms, although the chances subside as you head south toward central GA. Any convection should start to taper off by around sunset with skies clearing a bit there after. High temperatures will be cooler up north with better cloud and precipitation coverage...around the mid 80s. As you move south expect temperatures to be a bit warmer...around 90 in the metro and mid to upper 90s possible across central GA. Should be quiet overnight with lows around 70 areawide, apart from the cooler temps across the higher terrain. .SHORT TERM /Tonight through Tuesday Night/... 26 .LONG TERM /Wednesday through Monday/... No major changes to the extended forecast needed. Weak frontal boundary still progged to move through Thursday into Friday. NW flow will set up on the back side of the front for the weekend into the first part of next week. No real focusing mechanism for convection on Wednesday. The models are progging a weak shortwave to move east in the flow during the early part of the day. However, shortwaves like this are notoriously hard to time, but could help enhance any developing/ongoing convection. The front should serve to focus precip Thursday into Friday as it slowly sags south over the area. NW flow will set up on the back side of the boundary, which could lead to a good set up for MCS development into the weekend. Temperatures should remain at or slightly below normal for the period. NListemaa && .AVIATION... 18Z Update... A mix of MVFR/VFR cigs will continue across the region as showers move through north and eastern Georgia. Anticipate showers across metro TAF sites to dwindle while AHN will likely see more activity and possible thunderstorm development through the afternoon. Expect clouds to clear this evening as diurnal convection diminishes. We may see some patchy fog by morning, especially across portions of east GA. After sunrise, any low level moisture will mix out with typical CU development by mid/late morning. Expect a chance of showers and thunderstorms again tomorrow afternoon; highest chances being north of the metro TAF sites. Westerly flow through the period, around 6-8mph during the afternoons. //ATL Confidence...18Z Update... Medium on timing and coverage of convection. High on all other elements. 26 && .PRELIMINARY POINT TEMPS/POPS...

Scattered thunderstorms expected across mainly eastern Georgia late this afternoon and evening. A few storms could be strong with winds gusting up to 30 mph along with brief heavy rain. Due to the heavy rain, brief flooding of poor drainage areas could occur. The best time for thunderstorm development mainly along and east of a line from Rome to Atlanta to Macon to Vidalia. .DAYS TWO THROUGH SEVEN...Tuesday through Sunday... There is a chance of showers and thunderstorms each day, mainly during the afternoon and evening hours. A few storms could be strong to possibly severe with gusty winds as well as locally heavy rain. The best chances of isolated strong to severe storms will come on Thursday and Friday as a cold front moves across the region. Due to the heavy rain, brief localized flooding of poor drainage areas is possible. .SPOTTER INFORMATION STATEMENT... Spotter activation is not requested but spotters are encouraged to submit reports of severe weather through the web by going to weather.gov/atlanta.
