The episode as NWS PAH wrote it up.
Slow-moving thunderstorms with very heavy rain caused isolated minor flooding problems. The storms developed in response to daytime heating of a very moist air mass. A low pressure system drifted slowly eastward into the lower Mississippi Valley, tapping into a fetch of tropical moisture from the Gulf of Mexico.

Area Forecast Discussion National Weather Service Paducah KY 252 PM CDT Thu Jun 6 2019 .SHORT TERM...(Tonight through Saturday night) Issued at 230 PM CDT Thu Jun 6 2019 With the nice fetch of tropically sourced moisture, the slowly eastward drifting/stalling stacked Low pressure system will have plenty to tap into the form of showers/storms. These will tend to be diurnally enhanced and come in off and on waves over the next couple days, vs any prolonged duration/one place rainout. Still, the tropical nature suggests that locally heavier rains may be capable of producing some localized flooding issues, as depicted by day 1 (and 2) WPC outlooks for excessive rainfall. We have issued an SPS to highlight this potential hazard. Due to the clouds/pcpn/humid nature of the airmass, daytime temps will run near/slightly below seasonal norms in the low-mid 80s, while nighttime lows run above their seasonal norms in the low 60s. .LONG TERM...(Sunday through Thursday) Issued at 230 PM CDT Thu Jun 6 2019 An upper low will be over the middle Mississippi valley early Sunday. Models show the low weakening as it slowly moves east into Monday, with zonal flow over our region by Tuesday. Widespread showers and thunderstorms are expected Sunday, with chances decreasing and becoming focused across our eastern counties Sunday night into Monday. Dry conditions will return for Monday night into Tuesday evening. By late Tuesday night, ECMWF brings an upper level trof into the Mississippi valley. This produces some showers and storms in our northern and western counties late Tuesday night, with chances across the entire PAH forecast Wednesday into Wednesday evening. GFS is slower with the trof, and produces less QPF overall. At this point, will lean toward the ECMWF timing and keep pops late Tuesday night into Thursday in the slight to low chance category. Northerly surface flow Sunday into the middle part of the work week will keep temperatures at, then below, seasonal normals. Highs by Tuesday and Wednesday will be 5 to 7 degrees below normal, with dew points in the middle to upper 50s. && .AVIATION... Issued at 230 PM CDT Thu Jun 6 2019 Vicinity showers (possibly storms) will at times impact terminals this afternoon, then again become a more predominant feature late tonight-early tmrw, during the planning phase of the forecast. MVFR cigs will prevail mostly, although temporary breaks to VFR are possible. There is a chance a lowering of MVFR to IFR may occur during the planning period/toward the end of the forecast, and this was hinted at but not taken altogether on the midday package, should seek to reevalute/reaffirm in next 1 to 2 standard issuances. && .PAH WATCHES/WARNINGS/ADVISORIES...

As a low pressure system drifts eastward into the Mississippi River valley, it will stall and sling tropically sourced moisture northward across and throughout the valley. This will include all of our Quad State area. While overall rainfall amounts into the weekend may average, generally, in the 1 to 2 inch range, locally higher amounts will be possible. Be aware that if you get a particularly strong storm, or repeat showers and storms over the same area, you may experience temporarily at least, locally heavy downpours capable of producing flood issues. The entirety of the area is under a slight risk of rainfall exceeding flash flood guidance through tonight, and a marginal to slight risk exists Friday and Friday night as well. Remember to seek high ground if you notice rising waters, and never cross a flooded roadway. Be especially cautious at night, when rising waters are more difficult to detect. Humphrey/Lamm
