The episode as NWS PAH wrote it up.
Scattered thunderstorms increased during the warmth of the afternoon. The storms developed immediately ahead of a rather deep surface low over the lower Ohio Valley. A 500 mb low and its associated cold temperatures aloft promoted isolated large hail with the strongest storm. A cold air funnel cloud briefly touched down.

Area Forecast Discussion National Weather Service Paducah KY 1219 PM CDT Sat Apr 25 2020 .UPDATE... Issued at 1211 PM CDT Sat Apr 25 2020 Updated aviation discussion for 18z TAFs. && .SHORT TERM...(Today through Monday night) Issued at 350 AM CDT Sat Apr 25 2020 Upper level low pressure system will rotate east through the lower OH Valley today, bringing scattered to numerous showers to the region. Ahead of the associated surface low, currently located over sw MO, we may even see a few thunderstorms. Highest storm chances will will be over western KY this afternoon as the instability increases (500-1000 J/KG) ahead of the low during peak heating of the day. Cannot rule out a few stronger and possibly even an isolated severe storm or two as shear profiles favor some supercells potential, esp over the Pennyrile region of western KY. If convection manages to train, would need to monitor for some flash flooding potential also. Would not be unheard of to get a few cold air funnel reports underneath the upper low. General rainfall amounts are expected to be in the 3/4" to 1.5" category over much of the forecast region. A second wave of energy is expected to rotate southeast around the back side of the H50 low later tonight/Sunday. This will result in prolonged chances for at least some sct showers, mainly along/east of the MS River. Gradient winds will also kick up substantially behind the surface low tonight into Sunday. Will likely see some gusts 30-35 mph, but not expecting headline criteria (gusts over 40 mph) at this time. May warrant an SPS though. Looking as though things should finally calm down Sunday night into Monday as a narrow ridge of high pressure moves east across the region. Winds will turn more southerly on the back/west side of the surface high Monday afternoon/evening. This, along with some sunshine, should help boost afternoon temps back up to near 70 at most locations. .LONG TERM...(Tuesday through Friday) Issued at 350 AM CDT Sat Apr 25 2020 As a large ridge aloft builds over the western CONUS, northern stream shortwave energy in the mid levels is progged to vigorously dig southeastward through the Midwest Tue/Wed, possibly slowing down later in the week, if the 00Z ECMWF depiction verifies. Through Tue night, the medium range models were in reasonable agreement as to the positioning of the mid/upper system over northern MO at around daybreak Wed, with differences thereafter. After Wed morning, the ECENS/GEFS means were overall more progressive with the feature than the deterministic ECMWF. There is a reasonable expectation that this feature will bring a surface cold front through the PAH forecast area early Wed. Thus, the model signal remained for associated lift and instability to generate plenty of shower activity and isolated to scattered tstms Tue and especially Tue night ahead of the front, though instability/ lapse rates will be on a fairly rapid downside after nightfall. During this time, in the evening, the best bulk wind shear should be in place, at least in the western half of the region. As a result, while parameters for severe weather are not synchronized well, a strong storm or two cannot be ruled out late Tue. A dry slot to the southeast of the nearly stacked low may allow a reduction in cloudiness for part of Wed, especially west, and a general cessation in pcpn with time overall. However, clouds should return late with wrap-around energy associated with the mid/upper low. It will be quite breezy out of the west during the day. The National Blend of Models tended to keep small probabilities of measurable pcpn in the eastern third of the region for Wed night/ Thu likely due to the deterministic 12Z ECMWF solution, in part. We made slight downward adjustments to these PoPs because of the seemingly more likely aforementioned progressive scenario. Some adjustments off the blend were also made in the sky grids mainly for Wed to match PoPs better. Northwesterly flow aloft and surface ridging should keep the region's forecast dry for the Thu night/Fri period. Temps through the extended forecast period are expected to be near or above average, with a modest cool down Wed through Thu night. && .AVIATION... Issued at 1211 PM CDT Sat Apr 25 2020 SHRA activity will continue to increase in coverage this afternoon. Lightning activity will be possible east of the Mississippi River. -SHRA will gradually end in southeast Missouri this evening but will continue across most the rest of the area through the night and into the morning hours on Sunday. MVFR cigs will become more common by later afternoon and evening. Guidance is hinting at IFR cigs developing by later evening and continuing into tomorrow morning across the eastern half of the region (including KMVN/KEVV/KOWB). VFR conditions over the Ozark Foothills tonight will likely be slow to progress eastward towards KCGI until sometime during the day tomorrow. Other concern is gusty northwest winds of 25-35 kts possible this afternoon and evening, with strongest over southeast Missouri. A gradual reduction in wind gusts is expected overnight and tomorrow, although still in the 20-28 kt range. && .PAH WATCHES/WARNINGS/ADVISORIES... IL...None. MO...None. IN...None.
