The episode as NWS LMK wrote it up.
A storm system lifting out of the Tennessee Valley combined with existing heat and humidity to produce scattered strong to severe thunderstorms on August 6. One storm downed trees in Allen County, and heavy rainfall caused minor roadway flooding.
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 Louisville, KY wrote its last area forecast discussion before the first event at Aug 6, 1:02 PM CST, 3 hours 8 minutes earlier.
Area Forecast Discussion National Weather Service Louisville KY 302 PM EDT Sun Aug 6 2017 .Short Term...(This evening through Monday night) Issued at 352 PM EDT Sun Aug 6 2017 The short term period will be unsettled with a chance for a few strong storms as well as some minor flooding issues. Currently there is quite a contrast in weather across the region. An area of light to moderate rain across portions of central KY and southern IN has kept temperatures in the mid 60s. Meanwhile, clouds have started to clear out across far south central KY and mesonet temps down there have risen into the lower 80s. Through the remainder of the afternoon into the evening hours, there should continue to be some clearing and warming across mainly the southern two tiers of south central KY as a warm front lifts north. This will allow some instability to develop. Though shear is rather weak right now, short term models do have it increasing modestly across southwest central KY through the late afternoon. Scattered storms are expected to develop again across this region and continue to increase in coverage into the later evening hours. Though conditions are not overly favorable, a few stronger storms with gusty/damaging winds will be possible across this region. The area of rain further to the north should continue to push to the northeast and the latest model runs have it weakening and diminishing in coverage over the next few hours. For the evening and overnight, the warm front will continue to lift north into the region as a low pressure system approaches from the southwest. This low looks to cross central KY during the day tomorrow. Coverage of showers and storms will increase across the region tonight. Precipitable water values to rise to near two inches tonight with the high PWATS remaining in place in the warm sector across southern and eastern portions of the region tomorrow. Given the amount of moisture, some ponding of water or localized minor flooding will be possible, especially across central KY where showers and storms will linger longer Monday or areas that get repeated stronger storms tonight. Precipitation will end tomorrow evening as the low pressure system moves out. Temperatures through the short term are quite tricky. They may remain fairly steady across portions of the area tonight. Highs tomorrow will then be highly dependent on precipitation coverage and the path of the low across the region. However, tomorrow night lows should once again dip back into the upper 50s to mid 60s. && .Long Term...(Tuesday through Sunday) Issued at 301 PM EDT Sun Aug 6 2017 The long term period will start out quiet with below normal temperatures and dry weather through at least Wednesday morning. An inverted trough will then develop across east central Kentucky. This will result in rain chances creeping back into the forecast for east central KY Wednesday afternoon through Thursday. However, much of the region looks to remain dry through this period. The better chance for rain for everyone will come Friday into the weekend as a couple of shortwaves move through the upper flow aloft. At least scattered showers and storms can be expected each day from Friday through the weekend. Temperatures will warm up for the latter half of the week. Though they will still be slightly below normal, it will feel more like summer weather than it has the last couple of days. && .Aviation (18Z TAF Update)... Issued at 1255 PM EDT Sun Aug 6 2017 Warm front currently draped across south-central Kentucky very near BWG, with just enough instability to generate a broken line of convection on the boundary from BWG westward. All the lightning is showing up well to the west of the terminal thus far, but with continued heating it will likely warrant initializing with VCTS and CB mentions, and NE winds will come around to SE as the front tries to lift northward. Less convective character over north-central Kentucky this afternoon, so will just carry VCSH at SDF and LEX. VFR conditions will persist as even the CB and strato-cu look to remain scattered, with a prevailing mid-level ceiling this afternoon and much of tonight. Increasing coverage of rain during the night, with a few embedded thunderstorms, will lower ceilings with the strato-cu filling in toward morning. Could even go into fuel-alternate for a period of several hours Monday morning, especially at SDF, but not confident enough in direct impacts of convection to carry any restricted vis. && .LMK WATCHES/WARNINGS/ADVISORIES...
