The episode as NWS PAH wrote it up.
A squall line of thunderstorms moved southeast across portions of southern Illinois, producing isolated wind damage. This line of storms moved to the east-southeast at around 40 knots into a residual corridor of moderate instability. The line of storms occurred ahead of a cold front that extended from southern Lake Michigan southwest across the St. Louis metro area.

NWS Paducah, KY wrote its last area forecast discussion before the first event at Jun 18, 1:53 AM CST, 27 minutes earlier.
Area Forecast Discussion National Weather Service Paducah KY 253 AM CDT Sun Jun 18 2017 .SHORT TERM...(Today through Tuesday night) Issued at 253 AM CDT Sun Jun 18 2017 With the MCS entering the area and a Watch in effect will attempt to be brief. There appears to be plenty of instability to keep the MCS going across much of the area through daybreak, but not sure if the wind fields will be sufficient to keep the winds near severe levels. We have had a rash of 40-45kt observations just upstream, and hopefully it will stay in that range. Most of the available guidance indicates that the system should be weakening as we head toward daybreak, and the leading line convection certainly looks strongest from northwest Jefferson county northward, while the rest of the line looks rather unorganized. As for the watch we decided to err on the side of caution. It will likely be done well before 9 AM. The 00Z models are quite muddled with the surface pattern later today. The outflow from this system should push through the entire area regardless of the strength of the convection, and the cold front is not very well defined as it moves through our region. The convective debris will make it hard to destabilize today, and with the front not being very sharp/convergent, development may not be as widespread as previously thought, and it may take longer into the afternoon for it to develop. Not sure how much convection we will see and therefore severe storms seem like a long shot at this point. It still looks like it may take most of tonight to get the front and the last of the convection out of the area, but the cooler weather is still on track for Monday. Unfortunately, it will warm up above normal again on Tuesday. .LONG TERM...(Wednesday through Saturday) Issued at 253 AM CDT Sun Jun 18 2017 We will have weak high pressure over the area on Wednesday with dry but warm conditions. It will not feel as humid on Wednesday either with dew points progged to be in the lower 60s This high moves east during the day on Wednesday and into Wednesday night. We continue to watch a system that will be coming onshore in the Gulf. Of course models differ on the track of this system but both the Canadian and ECMWF bring moisture northward into our area Thursday into Friday. This will mean the humid conditions will be returning along with the chances for rain. The GFS shunts the system eastward into the Gulf Coast states and keeps the moisture to our southeast. If the Canadian and ECMWF are correct and that Gulf system or remnants thereof come right up the Mississippi River, we could see precipitation as early as Thursday night. These model differences affect the forecast for Friday as well. However, the GFS does indicate that deeper moisture will infiltrate the eastern parts of the forecast area by Friday. Therefore, we will continue advertising the best chances in the eastern half on Friday given the path of the aforementioned system. However, by Friday night into Saturday, we will be dealing with an incoming frontal boundary from the north. Timing is fairly good between models and good chances for convection will arrive Friday night and last at least through Saturday night. Models have been consistent in drying things out Sunday morning into the afternoon. We will see high temperatures a few degrees either side of 90 for Wednesday through Friday, with slightly lower temperatures on Saturday given clouds/precipitation and lower readings on Sunday behind the front. && .AVIATION... Issued at 657 PM CDT Sat Jun 17 2017 Main concern over the next 24 hours is with a thunderstorm complex forecast to dive southeast into the region overnight into Sunday morning. Gusty winds and lower cigs/vsbys can be expected with this activity. Preliminary indications are that this complex may reach far northwest counties around 05-07z and then progress southeast through the area, exiting much of the region by 14-16z. Timing is subject to change as some guidance is a bit faster or slower with the convective complex. The potential for another round of storms tomorrow afternoon across southeastern portions of the area is largely contingent on how the first round evolves. Most of this activity should be focused in western Kentucky. Otherwise, expect VFR conditions through much of the period outside of thunderstorm activity. Southerly winds tonight will tend to veer to the west as a cold front moves through on Sunday. && .PAH WATCHES/WARNINGS/ADVISORIES... IL...None. MO...None. IN...None.

These storms will likely be organized into a linear complex, so some threat of damaging winds will exist, especially across the northern portions of southeast Missouri and southern Illinois. The greater concern throughout the region will be heavy rainfall and lightning. .DAYS TWO THROUGH SEVEN...Sunday through Friday Scattered to numerous thunderstorms are expected Sunday through Sunday night with the greatest coverage over west Kentucky. A few strong to severe storms cannot be ruled out along and ahead of a cold front mainly over west Kentucky Sunday afternoon and evening. Damaging winds will be the primary severe concern, but heavy rainfall and lightning will be the greater concerns throughout the region. There is a chance of thunderstorms on Friday. A few storms may reach severe limits, along with heavy rainfall. .SPOTTER INFORMATION STATEMENT... Spotter activation may become necessary mainly over northern and western portions of the region after midnight tonight, and over west Kentucky Sunday afternoon and evening.
