The episode as NWS OHX wrote it up.
A large storm system stretching from the mid-Mississippi Valley northward into the Great Lakes region on September 2nd through September 4, 2022, along with an abundant amount of moisture resulted in scattered to numerous showers and thunderstorms across middle Tennessee. Due to slow storm motions and training of thunderstorms, heavy rain and areas of flash flooding were the primary threat during this event with impacts mainly felt near and south of Interstate 40. Several reports of flash flooding were received along with heavy rainfall totals of 3 to 6 inches.

NWS Nashville, TN wrote its last area forecast discussion before the first event at Sep 2, 1:44 PM CST, 5 hours 36 minutes earlier.
Area Forecast Discussion National Weather Service Nashville TN 244 PM CDT Fri Sep 2 2022 ...New SHORT TERM, LONG TERM... .SHORT TERM... (This afternoon through Saturday Night) Issued at 207 PM CDT Fri Sep 2 2022 The upper trough to our northwest over the mid MS River Valley is working to develop showers and storms over the area, but so far has struggled with the drier air aloft. A few light showers have popped up over the east in the past hour, but have struggled to maintain any strength. CAMs continue to show this development mainly along and east of I-65 this afternoon and evening, and possibly more activity west of I-65 later this evening and overnight. Southerly flow will keep moisture streaming into the mid state, even through the overnight hours and this weekend, so showers and storms will have plenty of moisture to work with as time continues. Models do disagree a bit on the strength of the instability/shear, but it remains on the lower end, so widespread strong to severe storms are not expected. But, some strong storms can not be ruled out, and may be able to produce some gusty winds but especially locally heavy rainfall. Some showers and storms will remain possible overnight, but more showers and storms will develop with diurnal help Saturday afternoon into the early evening. Lingering showers may hold on overnight into Sunday morning, especially in the east indicated by CAM guidance. && .LONG TERM... (Sunday through next Friday) Issued at 207 PM CDT Fri Sep 2 2022 By Sunday, the upper trough looks to extend from eastern TX up to the Great Lakes region, keeping the mid state in southerly flow and continued chances for showers and storms. Sunday does look to have increased chances compared to Saturday thanks to the upper trough broadening to our north and west. All models keep this trough over the same area through the week, with a potential developing closed low mid week and sinking southeastward towards TX. This will keep the rain chances in the forecast through next week, and keep the diurnal active pattern going. Right now, we have 1 to 3 inches of rain forecasted across the mid state, with the higher end of that range over the east. Obviously, with any stronger storms that develop, or any areas that see multiple rounds of heavier rainfall, higher totals will be possible. But at least with current solutions, no signals of any widespread severe weather is expected. The main threat starting tomorrow through next weekend will be isolated flooding concerns over saturated areas and locations that see multiple rounds of heavy rainfall. && .AVIATION... (18Z TAFS) Issued at 1245 PM CDT Fri Sep 2 2022 High pressure will slip to our east today allowing south winds to bring moist and increasingly unstable air into the region. Isolated showers or storms will develop this afternoon and evening, with scattered to numerous showers and storms on Saturday. Today's focus for showers will be on and near the Plateau, so VCTS was included for CSV. Otherwise, VFR will continue. As showers become more numerous, all sites will drop to MVFR Saturday morning. && .PRELIMINARY POINT TEMPS/POPS...
