The episode as NWS PAH wrote it up.
A mesoscale convective system moved east-southeast across southwest Indiana, producing locally heavy rainfall. The complex was fed by a southerly wind flow of tropical moisture, with precipitable water values over two inches. The south winds were in advance of a weak surface low pressure center over eastern Missouri.

NWS Paducah, KY wrote its last area forecast discussion before the first event at Aug 17, 4:28 AM CST, 32 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PADUCAH KY 528 AM CDT Sun Aug 17 2014 .UPDATE... Issued at 528 AM CDT SUN AUG 17 2014 Grids in fairly good shape. Will make a few tweaks to PoPs through the early morning. Overall, flooding has not been a concern. The exception has been a small area of Hamilton County, IL and points just north and west of there. That area will need to be monitored over the next few hours. Will update the Aviation section for the 12z TAFs. && .SHORT TERM...(Today through Tuesday night) Issued at 221 AM CDT SUN AUG 17 2014 Mid level circulation seen near KSTL with deep convection over portions of southern IL headed for southwest IN. Pockets of heavy rain, but no flooding concerns expected with this initial round. The mid level circulation will continue to drift ESE today, with a sfc low near KEVV by 00z. Best chances of convection will continue to accompany the low, with additional development expected with destabilization today, especially across the E/SE half of the area. A few strong storms cannot be ruled out, best chance southern sections. Maybe a pulse storm that could produce strong winds. Nothing major. Temps will be tricky again today given chaotic cloud cover and convection. Played it close to Raw Model output. Adjustments likely. With the departure of the low tonight, PoPs will continue to decrease from west to east. There may be enough moisture and destabilization over the east 2/3 of the area Monday for convection. Have low chance PoPs to cover that. Monday night may be dry for the most part. Have slights left in, mainly for any departing convection in the evening east, and possibly added development toward Tuesday morning from the west. Chance of convection will continue Tuesday into Tuesday night. Not much to focus on, but there is residual moisture and instability. Hard to rule activity out completely. .LONG TERM...(Wednesday through Saturday) Issued at 221 AM CDT SUN AUG 17 2014 Early Wednesday, an upper level low will be positioned over the Great Lakes. The atmospheric profile will be moist and unstable enough to warrant a slight chance of thunderstorms on Wednesday. Through the remainder of the period, an upper level ridge will build over the Lower and Middle Mississippi Valley. This will help to stabilize the atmosphere as the tropospheric profile undergoes a drying trend. Consequently, any slight chance for showers and thunderstorms will be suppressed into far eastern portions of the forecast area Thursday into the weekend. Hot weather fanatics who may feel cheated by the cooler than average summer will have reason to rejoice as high temperatures are forecast to reach the lower to mid 90s each day. Unfortunately, this will yield peak afternoon heat index readings near the century mark. && .AVIATION... Issued at 528 AM CDT SUN AUG 17 2014 Upper system moving into srn IL, continues to generate convection early this morning, mainly east of a KSAR-KMDH-KM30 line. Will have a few hours of convection at KEVV and KOWB. Nothing on radar west, so for KPAH and KCGI, will take redevelopment. Convection easily drops vsbys to around 1 mile or so, with ocnl MVFR cigs, heavy rain. This will continue to be the case with any convection through the day. Best chances of convection will gradually shift east with time through tonight. Winds will generally be either S or SW, but light. Variable and gusty within thunderstorm activity. && .PAH WATCHES/WARNINGS/ADVISORIES... IL...NONE. MO...NONE. IN...NONE. KY...NONE. &&
