The episode as NWS PAH wrote it up.
An area of disorganized thunderstorms over southwest Indiana evolved into a line of strong to severe storms as it moved southeast across the Ohio Valley. The storms evolved along the leading edge of outflow winds from an overnight thunderstorm complex. The storms were displaced to the south of the stronger winds aloft, limiting their severe weather potential. A few of the stronger cells produced damaging winds and heavy rainfall.

NWS Paducah, KY wrote its last area forecast discussion before the first event at Jun 10, 5:30 AM CST, 4 hours 24 minutes earlier.
Area Forecast Discussion National Weather Service Paducah KY 630 AM CDT Sun Jun 10 2018 .UPDATE... Updated aviation section for 12z taf issuance && .SHORT TERM...(Today through Tuesday night) Issued at 315 AM CDT Sun Jun 10 2018 Once again, the main forecast issue is the timing and coverage of convection. A warm and very moist air mass will remain in place, with little if any capping to inhibit convection. For early this morning, some convection remains possible in the Pennyrile region of west KY. This activity has been mainly in Tennessee so far early this morning. It appears to be associated with a weak 500 mb shortwave that will track southeast away from our region this morning. Later this morning, attention will turn to a well-organized mcs over northern Illinois. Numerical guidance has not been much help with forecasting convective systems the past couple days. The 00z ecmwf and a few high-res cam models take this system southeast across the Wabash Valley and Pennyrile region of west KY today. The latest hrrr guidance takes the mcs east-southeast, mostly bypassing our region to the north. This mcs is associated with a relatively strong 500 mb shortwave over the upper Mississippi Valley. The shortwave and its associated stronger winds aloft will move east-southeast to the Michigan/Indiana border area this evening. Regardless of the model of choice, it appears convection will develop today. If the Illinois mcs bypasses us to the north, it will likely generate an outflow boundary that would initiate convection over the lower Ohio Valley this afternoon. The air mass by then will be quite unstable, increasing the potential for pulse type wind events with stronger cores. The potential for strong convection might actually be lower if the mcs directly moves through our region this morning. The stabilizing effects of the mcs would keep convection limited this afternoon. In any case, the highest forecast pops will remain east of the Mississippi River today, closest to the impacts of the shortwave and mcs. Convection should diminish with loss of daytime heating this evening. On Monday, the air mass will become strongly unstable in the warm and moist southwest low level flow. There is less evidence of a forcing mechanism, so convective initiation would be tied to diurnal heating. It appears the best chance of storms will be in southwest Indiana and adjoining states, closest to a stalled frontal boundary that will be draped over central Indiana. Highs will be in the lower 90s, with heat indices near 100. On Tuesday, the potential for a few severe storms exists as a weak cold front approaches from the west. This front will be associated with a strong 500 mb shortwave moving east along the northern tier of states. Although the stronger winds aloft will be well to our north, moisture and instabilty is forecast to be quite supportive of intense updrafts. The stronger cores would be capable of some wind and hail in an enviroment favorable for pulse events. Peak heat indices will again be near 100. .LONG TERM...(Wednesday through Saturday) Issued at 315 AM CDT Sun Jun 10 2018 A very warm and humid pattern will continue into the weekend, with daily chances of storms. There is a higher than normal variability in the models, but none of them indicate a major change in the pattern. The 00z gfs and its ensemble mean is notably stronger with 500 mb ridging over our region, translating into hotter conditions through the period. The 00z ecmwf has not changed appreciably, so the forecast will remain basically status quo. Daytime highs will be around 90 with overnight lows near 70. Precip chances will revolve around a possible weak front that could waffle north and south across our region. The front would have little noticeable effect other than to increase dew point pooling and precip chances. && .AVIATION... Issued at 630 AM CDT Sun Jun 10 2018 Main concern is where and when thunderstorms will occur. The general trend again today should be for an increase in coverage and intensity as diurnal heating destabilizes the atmosphere. It appears the greatest coverage of storms will be in the kevv/kowb areas. A complex of storms early this morning appears likely to pass mostly north of kevv. However, renewed development of storms is possible around midday along any outflow boundary left by the morning complex. A decrease in storms is likely this evening as the atmosphere cools and stabilizes. Outside of storms, vfr conditions will continue. Areas of mvfr vsbys in fog early this morning will dissipate by mid morning. && .PAH WATCHES/WARNINGS/ADVISORIES... IL...None. MO...None. IN...None.
