What forecasters said that day
The local office's own words before this flash flood watch 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 flash flood watch went out at Jul 31, 2:10 AM EDT, 1 hour 40 minutes earlier.
Area forecast discussion, Jul 31, 2:10 AM EDT, 1 hour 40 minutes before
Area Forecast Discussion National Weather Service Peachtree City GA 210 AM EDT Tue Jul 31 2018 .PREV DISCUSSION... /Issued 1104 PM EDT Mon Jul 30 2018/ UPDATE... Thunderstorms have diminished across the area with only patchy pockets of residual rain remaining in the forecast area. The next several days will bring several rounds with 3-6 inches of precip expected across the forecast area through Friday with possible higher amounts locally. Flash Flooding and minor nuisance flooding will be the primary concern through this time period. PREV DISCUSSION... /Issued 252 PM EDT Mon Jul 30 2018/ SHORT TERM /Tonight through Tuesday Night/... Primary concerns are heavy rainfall and possible flash flooding as well as threat for strong/severe convection. Southwest flow aloft ahead of approaching positively-tilted upper trough already in place and will strengthen over the next 24 hours. Plume of deep moisture will also remain in place over the area through the short term period and into late Thursday or even Friday. Precipitable water axis progged by models to remain nearly stationary next 3 days over Westcentral to northeast GA and increase to 1.9 to 2.1 inches Tuesday and remain 2.0 to 2.2 inches Wed and Thurs. As of this writing, the GFS has been showing higher QPF than other medium range models, but expect this to vary from run to run. Nearly all model QPF at or higher than WPC guidance. While this is outside of short term period, pointing this out to emphasize ingredients for flash flooding coming together and a watch will very likely be issued sometime in the next 24-36 hours. With increasing moisture, mid level flow and vertical wind shear, also concerned about strong/severe convection during the short term period. Limiting factors will be thick clouds, moist-adiabatic lapse rates aloft and lower SBCAPE. Tuesday may be most favorable day of the week for severe storms as clouds and widespread showers increase and daytime temps remain cooler Wed/Thur. MLCAPE progged around 1500 J/kg today and Tuesday afternoon then drops to 800-1200 J/kg Wed/Thur. SNELSON LONG TERM /Wednesday through Monday/... A very wet pattern to start the long term as a long wave trough remains somewhat stationary across the central CONUS and an associated surface front slowly moves eastward. This will result in deep layer moisture moving across GA through Friday. Given plenty of upper level support, anonymously high PWATS, mid level shortwaves, moist SW flow and surface instability, we will likely observe ample coverage of showers and thunderstorms for days. Given there should be plenty of cloud cover, not sure how much convection will be realized during this period. However, any breaks in clouds through the afternoon hours will help to initiate thunderstorm development. Strong to severe storms are possible, but likely limited based on the aforementioned factors. The main concern will be flooding as moisture flux continues to stream into the region , with storm motion becoming somewhat parallel to the flow. This will lead to training concerns with localized flooding, especially late Tuesday through Friday. There are also signals for LLJ that would aid in better coverage of precipitation, especially during the overnights Tuesday through Thursday. A flash flood watch may need to be hoisted for portions of north and central GA. The largest precipitation estimates are around 3 to 5 inches with locally higher amounts possible. The area of most concern is across NE GA, SW toward LaGrange; this includes Athens and the portions of the Atlanta metro. Conditions improve after Friday as the main dynamics of this system move off to the north and the surface front becomes washed out. High pressure offshore will start to retrograde westward helping to suppress shower/thunderstorm activity. The weekend looks to be more of a typical summer-like pattern. Temperatures will be well below normal Wednesday through Friday given the precipitation/cloud cover expected. Temperature will begin to rebound by the weekend approaching climo by Sunday. 26 PREV DISCUSSION... / LONG TERM /Tuesday Night through Sunday/... The first half of the long term period will be dominated by unsettled weather, with high pressure returning by early next week. A frontal boundary will continue to inch eastward through the Gulf States through early Friday. This boundary should remain just west of the CWFA for Wednesday and Thursday and dissipate by the early part of the weekend. There is some uncertainty regarding if the boundary will make it into the far western CWFA before dissipating. Regardless, the airmass head of the front will funnel deep Gulf Moisture northward over the area, keeping pops above normal into the early weekend. High pressure begins to build into the region for the latter half of the weekend and the chances for precip should return to more normal values for this time of year. With broad troughing aloft and increased cloud cover due to precip/abundant cloud cover, temperatures will be below normal for the middle to late week. There is definitely some potential for flooding during the middle of the week. Currently, the models are projecting the highest rainfall totals along the I-85 corridor, but this axis will likely shift and it's too early to issue any type of flood watch. The most likely timing for heavy rainfall (right now) would be late Tuesday into Wednesday. NListemaa && .AVIATION... 06Z Update...
