$$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 30, 3:41 PM EDT, 3 hours 36 minutes earlier.
Area forecast discussion, Jul 30, 3:41 PM EDT, 3 hours 36 minutes before
Area Forecast Discussion National Weather Service Peachtree City GA 341 PM EDT Fri Jul 30 2021 ...Afternoon Area Forecast Discussion - Heat Advisories in effect today and tomorrow... .SHORT TERM /Tonight through Saturday Night/... Clouds earlier helped keep temperatures a little lower than originally forecast, but we are still climbing into the 90s across the area. Heat indices are broaching 100 across north Georgia and have already passed 105 in several locations across central Georgia and should continue climbing. Heat advisory remains in effect across most of north and central Georgia as a result. Otherwise, cu field is starting to mature in north Georgia and across eastern TN, where glaciation of cu is noted and there are even a few orphaned anvils from failed CI attempts. Expect some storms to begin to form in north Georgia very soon. CI in TN is being aided by weak frontal boundary that is pushing into the area and continuing to slowly sag to the south ahead of very weak impulse located within the broad upper level trough. Convective models have highlighted this area as having potential for some thunderstorms this afternoon as well, so have maintained PoPs across north Georgia tonight. There is a small chance of something reaching the metro, but chances look to be small at this time. Lows tonight will be quite warm in many places, only reaching into the mid to upper 70s. For overnight into tomorrow, weak front will push into north Georgia, especially if enough storms with cold pools form this evening, which should give some areas in the north a respite from the heat and humidity. However, the Atlanta metro is right on the border of this "cooler" air, and areas to the south will once again be very warm and humid, so have chosen to issue another heat advisory for tomorrow from the metro south. We may not quite make our number criteria of 105 on the northern end of the advisory, but after several days in a row of this, including overnight lows which remain quite warm, vulnerable populations, such as those without A/C, are getting little in the way of a chance to cool down and recover. Overall, did end up bumping temperatures down a bit in the forecast, which did preclude the need for excessive heat warnings in central GA. Afternoon mixing, combined with some chances for convection, should aide in keeping the heat indices down a little. Lusk .LONG TERM /Sunday through Friday/... Fcst period characterized by pattern shift as more enhanced moisture phases with a amplifying upper trough digging southward. For Sunday, thinking the blend might be too warm on resultant heat indices especially with aforementioned moisture return and expected increased convective coverage but cannot rule out perhaps another and possible last Heat Advisory to portions of the area to put this heat streak to bed. For pops, have likely to high end chance Sunday for most of area, and even categorical for central GA Monday as another piece of energy further amplifies. Little progression with overall trough is expected through the week, though should cutoff by midweek. There is some discrepancy on extent of the moisture axis east of the trough, but overall should support majority of the week to have a gradient of lower pops NW to greater SE. The environment most days looks to have marginally conditional instability with less than marginal deep layer shear near 30-35 kts so not expecting severe but multicell development or some more organized segments of storms could allow for localized increased wind threat with stronger storms. Also any perturbation traversing the low could aid forcing for a bit more organized convection and will have to monitor as we get closer with this setup. Baker && .AVIATION... 18Z Update... VFR conditions expected through the period. Only exception may be for very small chances of a thunderstorm affecting the ATL metro TAF sites this evening, though chances small enough to forgo any TEMPO for it. That is largest source of uncertainty. Winds will be W to NW otherwise from 4-10 kts. Expect cu field to develop each afternoon, otherwise just some cirrus about. //ATL Confidence...18Z Update... High confidence all elements, with only small uncertainty around metro TAF site thunderstorms this afternoon. Lusk && .PRELIMINARY POINT TEMPS/POPS...
