The episode as NWS FFC wrote it up.
With a very moist air mass persisting across the region, a stalled frontal boundary across north Georgia produced scattered reports of damaging winds and very heavy rainfall. Isolated flash flooding occurred, particularly where rainfall amounts topped 4 inches.
The local office's own words before the first event, 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 the first event at Jul 24, 2:31 PM EST, 54 minutes earlier.
Area Forecast Discussion National Weather Service Peachtree City GA 331 PM EDT Mon Jul 24 2017 .SHORT TERM /Tonight through Tuesday Night/... As of 18z this afternoon...the mid and upper levels featured a relentless ridge of high pressure over the western US and Southern Plains...with an active northern stream featuring several shortwave troughs and cyclonic flow across the Great Lakes and Northeast. Latest sfc analysis reveals an area of broad low pressure across southern New England/northern Mid Atlantic...with a low center across Lake Ontario and another near Long Island. From the L Ontario low extends a weak cool front across western PA SWWD across northern KY and southern MO..while a weak sfc trough extends from the Long Island low into the Carolinas and Georgia. Convection is well underway once again across the CWA. Most likely forcing behind this activity is the weak sfc trough located across north Georgia. Overall evolution argues for pulse thunderstorms driven by weak outflow boundaries...with perhaps a few cells merging into loosely organized clusters. Main threat this afternoon and evening will be strong downdrafts as SPC mesoanalysis reveals low level lapse rates in excess of 7C/km and PW values near 2 inches. Convective coverage should be on a downward trend after sunset with loss of daytime heating...with some nuisance showers likely lingering into the overnight. Late in the overnight period into Tuesday could be interesting. Current GOES-R IR imagery reveals some healthy convection across LA/MS. At this point all medium-range models are picking up on a convectively induced perturbation associated with this Gulf Coast MCS moving into the CWA from the west late tonight. Although hi-res solutions are not picking up on early morning precip at this point...find it very hard to believe that upper level synoptic lift will not have any impact on such a moist and unstable environment. Not to mention this shortwave will also have a sfc trough to interact with. Have increased POPs to account for this. Should the convective perturbation dissipate upon reaching the CWA...there will not be much shower activity. New EC data agrees with CMC GFS and NAM that a vort max will be on our western border at 12z. In addition, morning convection/showers could have an impact on diurnal convection later in the day...not to mention high temperatures. At this point it is hard to draw a solid conclusion on this forecast until the LA/MS MCS evolution becomes more clear. Kovacik .LONG TERM /Wednesday through Monday/... Extended range models continue to show a pattern that resembles anything but late July. Strong shortwave dives out of the plains late Fri into Sat and allows front to enter the area with even some weak low pressure areas forming along the front. Moisture and dynamics support categorical pops on Sat but dont want to go to high just yet given such an anomalous pattern. Cooler temps in the offing but still will feel summerlike with the abundant moisture. Deese && .PREV DISCUSSION... LONG TERM As the long term period begins...the forecast area remains on the edge of the Bermuda high and in a weak upper trough. A frontal boundary gets pushed into north GA early in the period and some drying can be noted for a portion of the north. However not seeing enough drying to remove pops completely...and we should expect a continuation of mainly diurnal showers and thunderstorms. By Saturday a long wave trough developing over the eastern states should push another front southward into GA. However GFS and ECMWF keep cyclonic flow over the southeast through the weekend. So have continued with persistence pops. Temperatures should range around normal numbers through the period. 41 AVIATION... 18Z Update... Complicated TAF cycle in store. For today, thunderstorms will increase in coverage through early evening...with the threat for a few strong downbursts. All sites have a TEMPO currently thru 22z but this will likely need to be extended through at least 00z. Could see some clearing to some extent tonight but focus then turns to a convectively induced disturbance moving in from the west. Forecast may be too optimistic right now...but potential is there for MVFR/IFR cigs /perhaps lower/ along with an early arrival of showers and embedded thunder /09z-12z?/. Potential for fog will also exist. NW winds this afternoon will become more SW overnight before becoming more NW Tuesday morning at less than 10kts. //ATL Confidence...18Z Update... High on convective elements today High on wind direction and speed Low on all other elements. Kovacik && .PRELIMINARY POINT TEMPS/POPS...
