During the afternoon and evening hours on August 3rd, showers and thunderstorms developed over north central Tennessee, eventually drifting northeast into south central Kentucky. Afternoon temperatures in the low 90s and dewpoints in the low-to-mid 70s contributed to the development of an unstable environment, with 2000-3000 J/kg mixed-layer CAPE over the region.

The episode as NWS LMK wrote it up.
During the afternoon and evening hours on August 3rd, showers and thunderstorms developed over north central Tennessee, eventually drifting northeast into south central Kentucky. Afternoon temperatures in the low 90s and dewpoints in the low-to-mid 70s contributed to the development of an unstable environment, with 2000-3000 J/kg mixed-layer CAPE over the region. However, environmental shear was weak, limiting the potential for widespread strong or severe thunderstorms. However, one particularly strong storm was able to grow enough to produce isolated wind damage across Clinton County.

NWS Louisville, KY wrote its last area forecast discussion before the first event at Aug 3, 6:04 PM CST, 1 hour 26 minutes earlier.
Area Forecast Discussion National Weather Service Louisville KY 804 PM EDT Wed Aug 3 2022 ...Updated Aviation Discussion... .Short Term...(This evening through Thursday) Issued at 305 PM EDT Wed Aug 3 2022 Another steamy night ahead for the Ohio Valley as convection developing over northern Illinois won't make it this far southeast. Cold front still back over the Upper Midwest, but the effective boundary runs from near Chicago to between Springfield and Quincy. The northern end of this line will be carried almost due east by the flow aloft, while the southern/western end will be left behind to dive southward down the Mississippi Valley. We'll have slight chance POPs in southern Indiana toward daybreak as convective remnants try to push into the area. Best chances of rain Thursday morning will be across southern Indiana, but thunder chances will be decreasing at that point. However, we'll have copious moisture (PWATs near or above 2 inches), decent instability and a boundary-rich environment in the afternoon, so expect storms to re-develop. Likely/categorical POPs across most of the area for the afternoon, with very slow storm motion to support a heavy rainfall threat, along with a wind threat from pulse storms if we can get cold pool interactions. .Long Term...(Thursday night through Wednesday) Issued at 300 PM EDT Wed Aug 3 2022 Long term period will feature hot and humid conditions, along with daily shower and storm chances as we remain in a WAA pattern south of a weakening cold front. Aloft, a shortwave trough will be cutting through the northern Ohio Valley, with a deep high pressure system situated over the southwest US. To the east, a retrograding Bermuda high will approach the US East Coast, enhancing the south- southwesterly flow and Gulf moisture fetch into the Ohio valley. With not much change to the airmass through the weekend, Friday thru Sunday should feature diurnally-enhanced PoPs. Daily afternoon highs in the mid to upper 80s along with humid dewpoints in the mid to upper 70s will not only support heat indices approaching the mid to upper 90s, but also moderate instability as well in a rather high PWAT airmass. Generally weak flow aloft will help limit our shear values, but in doing so, will likely result in slow storm motions for the weekend. With high PWATs and CAPE expected to be in place, torrential rainfall, frequent lightning, and gusty winds will be the primary hazards at play. Should see a decrease in convective activity around sunset each day as peak heating is lost. Warmest days of the period come Saturday and Sunday, with highs closer to 90 each day. This will be a result of the southwest US high expanding further east into the Central US. As we get into the early part of next week, the upper high pressure with retract back to the Four Corners region as another upper level shortwaves dives into the Ohio Valley. At the sfc, an extensive cold front stretching from New England to the Plains will provide additional rounds of shower and storm chances for Mon-Wed. As the front approaches the Ohio River vicinity, it will slow down and take it's time getting through the region. Low level jetting ahead of the front will continue to provide plenty of WAA and moisture advection, so will carry fairly high PoPs into next week. && .Aviation...(00Z TAF Issuance) Issued at 803 PM EDT Wed Aug 3 2022 We are going to begin the period with VFR conditions at all are TAF sites, but as we head into the late morning hours, tomorrow, precipitation chances will begin increasing at HNB and SDF. Believe HNB has the best chance of seeing multiple showers/storms throughout the day. Timing confidence is low, but not expecting non-stop precipitation. Most of the day will likely be dry with a few passing showers. BWG and LEX can expect to see a shorter window of activity confined to the afternoon. && .LMK WATCHES/WARNINGS/ADVISORIES... IN...None.
