The episode as NWS PAH wrote it up.
Multiple rounds of thunderstorms impacted southwest Indiana on the last day of May. The first round of storms moved through southwest Indiana during the late morning and early afternoon hours. Scattered thunderstorm development then began by mid to late afternoon, with coverage increasing further into the evening hours. A subtle shortwave trough across the mid Mississippi Valley and lower Missouri Valley provided large-scale ascent for the nighttime round of storms, which caused some flooding early on the morning of June 1st.

Area Forecast Discussion

1254 AM CDT Fri Jun 1 2018
.UPDATE...
Issued at 1254 AM CDT Fri Jun 1 2018
Just killed off the last of Severe Watch #142, as the outflow
boundary has cleared that entire area. Previously extended the
Flash Flood Watch until 3 AM to allow the heavy rain producing
storms in that are plenty of time to clear.
The AVIATION section has been updated for the 06Z TAF issuance.
UPDATE Issued at 807 PM CDT Thu May 31 2018
Updated to replace tornado watch with a severe thunderstorm watch.
&&
.SHORT TERM...(Tonight through Saturday night)
Issued at 425 PM CDT Thu May 31 2018
Given the mesoscale nature of the training thunderstorms from the
confluence the Mississippi and Ohio River eastward through west
Kentucky and extreme southern Illinois, will hold off extending
the Flash Flood Watch further west to include the impacted
counties. The foci for this convective boundary did not come into
play until the middle of the afternoon, so it may be too late to
consider a downstream watch at this time, but will monitor.
Discrete cells are still developing in in south central Missouri,
so still feel SPC's tornado watch call for southeast Missouri into
southwest Illinois is warranted. The local eastward extension
will remain, given the enhanced shear/instability possible along
the boundary extending into the southern Pennyrile.
Most of the forcing associated with trough/upper low should move
east of the majority of the WFO PAH forecast area after 06z Friday
(1 am CDT). Lingering convection may remain in the eastern
counties through the late morning on Friday.
Depending on the amount of insolation and temperature recovery
tomorrow morning, heat index values may rise back into the middle
and upper 90s over southeast Missouri. Given the uncertainty, may
remove a mention of heat index values at or above 100 degrees on
Friday in the hazardous weather outlook.
The signal for strong to severe convection looks likely again
for late Saturday afternoon and evening. Given the negative tilt,
shear, and narrow zone of instability associated with the
northern Plains/upper Midwest trough, cannot rule out severe
weather again.
.LONG TERM...(Sunday through Thursday)
Issued at 425 PM CDT Thu May 31 2018
Northerly flow and high pressure will dominate the remainder of
the WFO PAH forecast area for the extended forecast period. Have
average confidence that dry weather will persist through
Wednesday, but for now will keep the forecast close to the
regionally initialized model guidance in collaboration with
surrounding NWS offices.
&&
.AVIATION...
Issued at 1254 AM CDT Fri Jun 1 2018
Main concern for this set of forecasts is the ongoing convection
which will impact KOWB for the next hour or two with IFR or lower
conditions. It may continue with VCTS and light rain at KEVV for
the first hour of the forecast. If there is sufficient clearing,
some at least MVFR fog development will be possible throughout the
area by sunrise. Otherwise, VFR conditions are expected with
light winds.

Damaging winds and large hail will be the primary hazards. The initial thunderstorms this afternoon may be isolated, discrete supercells, gradually developing together to form a line of strong to severe thunderstorms. An isolated tornado cannot be ruled out of the question at this time. There is also a good potential for the training of storms this afternoon and this evening and may produce some localized flash flooding concerns. Heat index values may reach 100 this afternoon near the confluence of the Ohio and Mississippi Rivers and southward to the Missouri Bootheel. .DAYS TWO THROUGH SEVEN...Friday through Wednesday A chance of thunderstorms is forecast for portions of the area on Friday, particularly across western Kentucky. Locally heavy rain and lightning will be the main hazards. Another chance of thunderstorms is forecast Saturday afternoon through the night. Some of these storms may be severe with damaging winds and large hail along with torrential rainfall and lightning. Afternoon heat index readings may approach 100 degrees on Saturday afternoon across portions of southeast Missouri. .SPOTTER INFORMATION STATEMENT... Spotters should be prepared for activation throughout the area this afternoon and evening, and again Saturday afternoon and evening. DRS/SP/Smith
