The episode as NWS FFC wrote it up.
Scattered showers persisted along the wedge boundary on the morning of September 15th. Training showers produced 3 to 4 inch rainfall totals across eastern Putnam, Hancock, Washington and Glascock counties. In Glascock county, runoff from these rainfall amounts resulted in the quick rise of Joes Creek, resulting in a road washout.

Area Forecast Discussion National Weather Service Peachtree City GA 751 AM EDT Fri Sep 15 2023 ...New 12Z Aviation Discussion... .SHORT TERM... (Today through Saturday) Issued at 421 AM EDT Fri Sep 15 2023 Current radar loop shows some scattered showers mainly across eastern portions of the state this morning. These showers appear to be holding on to the wedge front building into NE GA. This wedge of high pressure is expected to continue to move SW into the state today pushing the main axis of moisture SW with it. This should put the greatest chances of precipitation across central and west central GA this afternoon and evening. Hi-Res models showing a fairly active afternoon across western and southern portions of the CWA before the precip pushes into AL later this evening. This wedge is fairly weak and will not hold onto the area for long as it begins to retreat back to the NE early Sat morning. This will allow the moisture axis to move back east over the area increasing precip chances for all of North and Central GA Sat afternoon. Not looking for much in the way of severe storms as instability indices do not support this Today or Sat. The biggest concern with any storms that do develop will be the possibility of flooding. Precipitable water values are expected to be in the 1.5" to 1.8" range through the short term, so any slow moving storms could drop a lot of precipitation fairly quickly. Temps expected to be much cooler Today and Sat with highs in the 70s and lower 80s. 01 && .LONG TERM... (Saturday night through Thursday) Issued at 421 AM EDT Fri Sep 15 2023 As the extended period begins on Saturday night, the upper level ridge and associated surface high pressure will be moving eastward offshore. Return flow on the back side on the western side of the high will contribute to deepening moisture, with dewpoints climbing into the mid to upper 60s and precipitable water anticipated to remain between 1.5-1.8 inches. A longwave trough will meanwhile extend from eastern Canada to as far south as the northwest Gulf of Mexico. This trough will progress eastward over the course of the day on Sunday and approach the Atlantic coast by midday Monday. As the trough moves over the lower Mississippi River Valley, a weak surface low will develop over the central Gulf Coast. This low, and an associated cold front trailing to the south, will lift northeastward across Georgia on Sunday afternoon. Scattered showers and thunderstorms are expected across the forecast area, with the best chances in the region of forcing ahead of the surface low and cold front. At this time, the best mid-level forcing and shear are expected to remain well north of the forecast area at this time, limiting the potential for severe weather. However, a few storms could become strong in portions of central Georgia where instability will be greatest. The front is expected to clear the forecast area by early Monday morning. After this point, precipitation chances will come to an end, and a cooler, drier airmass will filter into the forecast area from the northwest. The axis of the trough will clear the area by Monday afternoon, with weak ridging setting up over the Southeast CONUS. As high pressure settles in over much of the region, temperatures will run near seasonal normals, with lows in the mid to upper 50s in north Georgia and upper 50s to low 60s in central Georgia and highs in the low to mid 80s. In fact, dewpoints in the 50s will have it feeling quite refreshing outside through midweek. King && .AVIATION... (12Z TAFS) Issued at 741 AM EDT Fri Sep 15 2023 Showers have continued all night but things are coming together a bit. Slightly drier air is filtering into NE GA as the wedge builds in. The showers are slowly moving south and west and should continue pushing SW of the ATL area through this afternoon. Will see showers this afternoon mainly across the MCN and CSG areas as the main axis of moisture moves southwest through the day. Winds expected to stay out of the E to SE in the 6-12kt range. VSBYs expected to stay in the VFR range as well. //ATL Confidence...12Z Update... Confidence high on all elements 01 && .PRELIMINARY POINT TEMPS/POPS...

Scattered showers and isolated thunderstorms will continue across north and east Georgia this morning. Scattered thunderstorms will be more focused across west and central Georgia by this afternoon. While widespread severe weather is not expected, a few storms this afternoon could become strong, capable of producing gusty winds and frequent lightning. Slow-moving strong storms could furthermore produce locally heavy rainfall and lead to isolated flash flooding concerns. .DAYS TWO THROUGH SEVEN...Saturday through Thursday... Isolated to scattered thunderstorms are expected across the area on Saturday and Sunday. A couple of strong or severe storms cannot be ruled out, but widespread severe weather is not anticipated at this time. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed through tonight.
