The episode as NWS PAH wrote it up.
A few supercell thunderstorms formed over southeast Missouri during the warmth of the afternoon. The storms gradually intensified immediately ahead of a cold front across southeast Missouri, where lower 60's dewpoints were in place. Pockets of diurnal heating resulted in moderate instability, with mixed layer cape values from 1500 to 2000. A moderately strong low level southerly wind flow was adequate for a brief tornado or two. With deep-layer winds oriented perpendicular to the initiating cold front boundary, conditions were favorable for supercells capable of locally damaging winds, isolated large hail, and a brief tornado.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Paducah, KY wrote its last area forecast discussion before the first event at Apr 30, 1:47 PM CST, 1 hour 47 minutes earlier.
Area Forecast Discussion National Weather Service Paducah KY 247 PM CDT Sat Apr 30 2022 .SHORT TERM...(Tonight through Sunday night) Issued at 130 PM CDT Sat Apr 30 2022 The RAP did a good job depicting the corridor of drier air over our CWFA centered between two low trop moist axis to our east and west. Surface dew points have dropped into the 50s most of the area, with a lot of debris cloudiness over the west 1/2 of the CWFA. SPC just issued a mesoscale discussion for our area. But overall our thinking has not changed. While there is certainly a risk for a few severe storms, we are not expecting a big event. Better forcing for ascent with jet dynamics stay more to our north. Not much speed shear with flow at and above 700mb staying in the 40-45 kt range up to near the EL. The one area we continue think might have the best chance of isolated severe is SEMO, into briefly far west KY and the southern tip of Illinois. This is supported by higher probabilities seen across this area in the SSCRAM (RAP/HRRR), with the most likely hazards marginally severe hail and high wind. After 00z, the low level flow actually weakens with 40kts of S/SW flow dropping down to 25 kts or so. MLCAPES that peak 1500 j/kg or slightly higher in the aforementioned areas quickly diminishes south as well. So the window of opportunity does not seem all that long into the evening. For storm mode, mainly clusters, or short line segments. There could be a brief supercell storm or two, again in the favored areas mentioned. As the parent system to our north heads into Canada, and after the weak front moves across the area, our chance for convection will end from west to east tonight, with dry weather expected Sunday and Sunday night. It will be breezy and warm Sunday. .LONG TERM...(Monday through Saturday) Issued at 244 PM CDT Sat Apr 30 2022 The first of many 500 mb shortwaves will set the stage for a fairly active week as the chance for pcpn will be on the increase during the afternoon Monday, especially across southeast MO. The period with Categorical PoP does not begin until Monday night as showers and tstms will increase in coverage across the FA. Elevated CAPE will be the greatest across southeast MO and the Purchase Region of west KY where SPC currently has a marginal risk for severe weather. The main hazard will be the potential for some hail. Risk for showers and tstms then continues through Tuesday as a sfc low pressure moves across the Ohio Valley with a trailing cold front. A few strong to severe storms with strong winds and frequent lightning are possible as GFS BUFKIT soundings show CAPE values around 1500- 2000 J/KG and steep mid level lapse rates. High temps during this period will range from the mid to upper 70s for most locations. The risk for showers and storms may linger into Wednesday morning if the front remains close enough to the FA, especially near the TN border. However, the more likely scenario is for the front to stall far enough south allowing for dry air to build in as a sfc high pressure passes by to the north. Pncpn chances will gradually lower from north to south. Temps will also be a bit cooler with highs only near 70 degrees. Lower confidence once again begins Thursday as models differ in the timing of a sfc low pressure system that looks to move through the lower Ohio Valley. The 12z ECMWF/CMC are in better agreement compared to the 12z GFS which remains the big outlier with pcpn arriving early Thursday morning. While PoP chances are more likely across western counties in the afternoon, would favor the Thursday night into Friday time frame for when pcpn will be the most widespread across the area. At the moment, it appears the greatest instability will remain to our south with more organized storms; however, it will not take much of a shift north with the sfc low to bring the better parameters for storms into the PAH CWA. Too early to go into details for Saturday as it is unclear how quickly pcpn chances will diminish. High temps will range from the upper 60s to mid 70s during the period. && .AVIATION... Issued at 130 PM CDT Sat Apr 30 2022 As a front moves into and then across the area this afternoon and tonight, scattered to numerous showers and thunderstorms will move across the area. We have a mention in the terminal forecasts. Overnight, VFR conditions return as cloud cover will be on the decrease. SSW winds 10 to 20 kts with higher gusts will diminish as winds veer to the west generally less than 10 kts overnight. && .PAH WATCHES/WARNINGS/ADVISORIES... IL...None. MO...None. IN...None.

&&The St Louis radar (KLSX), 191 km away, was scanning. The volume nearest the first event began at 21:36 UTC.
6 hail, 4 thunderstorm wind, 1 tornado. Local standard time, as filed.
A severe thunderstorm tracked roughly along U.S. Highway 60 through much of Carter County. Quarter-size hail fell in Van Buren. Golf ball size hail was observed near the junction of U.S. Highway 60 and Highway 21N, several miles east-northeast of Van Buren.
Tree limbs from two to three inches in diameter were down. This supercell thunderstorm also produced large hail from Van Buren east-northeast along Highway 60.
Trained spotters reported large hail from quarter size to ping-pong ball size. The large hail occurred in a west to east swath around the Perryville airport. The large hail accompanied a supercell thunderstorm across northern Perry County. Damaging winds and a brief tornado occurred just slightly south of the hail swath.
A weak tornado briefly touched down on County Road 806 within a larger area of straight-line winds. The evidence of the weak tornado was based on the orientation of the damage. This included uprooted trees oriented to the southeast, along with lofted tin from a nearby damaged machine shed and a large two-by-four impaled into the ground. The tornado also destroyed a 30-by-50 foot machine shed near some other tree damage in the vicinity. The home next to this machine shed sustained damage to its soffit and gutters. The siding was damaged by debris. Power lines were down. A trained spotter reported seeing a funnel cloud. Peak winds were estimated near 85 mph.
An small area of damaging straight-line winds occurred on the west side of Interstate 55 on County Road 806. The wind damage area was about 0.4 mile wide and included many large downed trees and tree branches. There was also some shingle damage and a roof torn off a barn. A small EF-0 tornado was embedded within this damage area.
Ping pong ball size hail was reported on HH Highway near Clearwater Lake. Quarter size hail fell in Leeper. This swath of large hail was associated with a supercell thunderstorm over Carter County that weakened as it moved through western Wayne County.
A trained spotter estimated a wind gust to 60 mph. These strong winds were associated with the supercell thunderstorm that caused significant damage and a brief tornado near Brewer.
A barn was leveled, and a building roof was damaged. Farm equipment was damaged. Power lines were down. This wind damage was associated with the same supercell that produced large hail, wind damage, and a brief tornado in the northwest and north central parts of Perry County.
This large hail was associated with the same thunderstorm that caused large hail in Piedmont.
