The episode as NWS PAH wrote it up.
Multiple rounds of severe thunderstorms impacted the Quad State region on the 27th. The later rounds of storms began with isolated to scattered storms tracking northeastward late afternoon into the early evening. On the synoptic scale, an upper level jet ejected across the Missouri Valley during the evening with a pronounced mid level wave moving through. The low level jet strengthened into the evening. A surface low was positioned near St Louis during the early evening with a trailing cold front extending southwestward. A broken band of supercells developed along this and eventually congealed into more linear segments as it moved into Southern Illinois and West Kentucky compared to its more discrete structure in Southeast Missouri.
In Northwest Kentucky, during the late evening, MLCAPE remained elevated ahead of the frontal boundary with values of 1000-2000J/kg, along with deep layer shear of 50-60kts, STP of 4-6, and mid-level lapse rates of 8C.
Reports from West Kentucky primarily came from an intensifying line of storms entering the Western Coal Fields area from the northwest. The most significant damage came from a surging portion of the line with an embedded supercell that resulted in two tornadoes: 1. an EF-0 tornado which crossed from northeastern Hopkins County into McLean County, and 2. an EF-1 tornado which caused damage from southeast of Rumsey to north of Livermore in McLean County. A swath of straight-line winds accompanied the first tornadic circulation. The tornadoes damaged numerous trees, some electrical lines and power poles, and a few homes and outbuildings. Several other straight-line wind damage reports were received.
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 27, 5:37 PM CST, 4 hours 50 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Paducah KY 637 PM CDT Mon Apr 27 2026 .KEY MESSAGES... - A significant severe weather event will impact the Quad State this afternoon into tonight. Elevated isolated supercells this morning that are capable of producing large hail will become surface based this afternoon. Strong tornadoes, very large hail, and damaging winds will all be possible. Discrete storms grow upscale into a line tonight with damaging winds and embedded strong tornadoes. - Breezy conditions will continue through this afternoon with wind gusts between 25-35 mph. There is a 40-50% chance wind gusts briefly reach 40 mph. - Another round of severe weather is possible late Tuesday afternoon into Tuesday evening. Very large hail, damaging winds, and isolated tornadoes are the hazards of concern. There is a 60-70% chance of total 48 hour rainfall of 2 inches or more. Localized flash flooding issues are possible. - Temperatures trend near to slightly below normal Wednesday into next weekend. Most of the period is dry, but a 20-30% chance of light rain showers return on Friday. && .UPDATE... Issued at 637 PM CDT Mon Apr 27 2026 Updated aviation section for 00z TAF issuance. && .DISCUSSION... Issued at 1112 AM CDT Mon Apr 27 2026 Elevated convection is ongoing across the Quad State this morning, with isolated supercells that have been producing large hail. As the back edge of the MCS lifts more northeast, destabilization will quickly occur with an influx of higher dewpoints near 70 degrees pushing northward across the Missouri Bootheel. The air mass recovery by this afternoon quickly translates to 2500 to 3500 J/kg of SBCAPE and 7.5 to 8.0 C/km mid-level lapse rates. Combined with 300-400 m2/s2 of 0-3km SRH and STP values of 3.0-6.0, strong EF3+ tornadoes, large hail over 2 inches, and damaging wind gusts over 60 mph will all be possible. The storm mode this afternoon will be more discrete with the HRRR showing a cluster of supercells developing. As a meso low near STL lifts northeast this evening, the winds at the sfc become more backed, especially in SPCs 15% tornado risk that clips portions of southeast Missouri and southern Illinois. While the ongoing convection has always been the greatest uncertainty with the forecast, model consensus continues to remain strong for the storm mode to transition to line segments this evening with convection rapidly growing upscale into a QLCS. This is when the highest damaging wind risk will occur with DCAPE over 1200 J/kg. Embedded strong tornadoes also remain likely with sfc-1 km shear around 30-35 kts. Instability begins to drop off as storms move into southwest Indiana and the western Kentucky Pennyrile, allowing for some weakening into the overnight hours. Breezy conditions are expected outside of thunderstorms through this afternoon with a 40-50% chance of wind gusts briefly reaching 40 mph locally. Most gusts however should remain in the 25-35 mph range. Given the brief duration, have decided to hold off on issuing a Wind Advisory as the impacts will be subtle compared to the severe weather that will impact most of the FA. The potential for another round of severe weather continues to increase on Tuesday as another wave moves trough with a stalled frontal boundary. The CAMs show a MCS pushing across southeast Missouri and western Kentucky Tuesday afternoon into Tuesday evening. The thermodynamics support damaging wind and very large hail with 1500 to 2500 J/kg of SBCAPE and mid-level lapse rates between 8.0-9.0 C/km. The tornado risk will be more isolated with lower intensity compared to today, but 15 kts of sfc-1 km shear will be enough to support a few spin ups. If the boundary shifts more north and convection trends slower, convection would overlap with the better 40 kt LLJ in the evening to support a higher risk. Due to the potential for training convection, the risk of localized Flash Flooding has increased with another 3 rounds of thunderstorms expected through Tuesday evening. Total 48 hour rainfall is forecast between 1.5 to 3.5 inches, with a 60-70% chance of 2 or more inches. Given the ongoing drought conditions, flooding issues will be more prone to the typical urban and low-lying locations that are more sensitive with PWATs around 1.5 inches. Dry and much cooler conditions return on Wednesday with a broad trough aloft settling over the Ohio Valley. Daily slightly below normal high temperatures range from the mid 60s to near 70 through Friday before trending warmer closer to normal next weekend. There remains a 20-30% chance of light rain showers on Friday. The GEFS is further north with a low pressure system that tracks over the lower Mississippi River Valley with QPF between 0.10 to 0.25 inches. Meanwhile, the EPS and GEPS keeps this system more suppressed with very little rainfall. A dry weekend then follows as sfc high pressure builds in. && .AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/... Issued at 637 PM CDT Mon Apr 27 2026 Shra/tsra possible at all TAF sites through 07z, and some strong to severe storms with gusty winds and hail are possible between mainly 02z-07z. MVFR/IFR conditions possible with storms. Away from storms and through the TAF period, VFR conditions expected with cigs between 3500-9000, becoming SCT after 08-11z. Winds from the south to southwest at 10-20kts with gusts to 25-30kts will become northwest at 5-12kts after 08z, with decreasing speeds through the night. Shra/tsra return very late in the TAF period at KCGI/KPAH. && .PAH WATCHES/WARNINGS/ADVISORIES... IL...None. MO...None. IN...None. KY...None. && DISCUSSION...DW AVIATION...RST

11 thunderstorm wind, 3 tornado. Local standard time, as filed.
Multiple trees were downed across roadways in Henderson as a storm pushed eastward through town.
Multiple trees were downed on Alves St, one of which fell on cars. Time estimated from radar.
A tree was downed across KY-1078 between KY-35 and US-60 east of Henderson.
A strengthening rear inflow jet resulted in multiple trees being downed along KY-370 at the Hopkins-Webster County line. An outbuilding was leveled with debris spread out. Time estimated from radar.
Several trees were uprooted off of KY-370 west of the intersection with Weldon Rd. A broader area of divergent tree damage on KY-370 and Ashbyburg Rd was observed north of the tornado damage path.
An EF-0 tornado, with estimated peak winds of 85mph, began along Ashbyburg Rd and tracked eastward. Trees were snapped and uprooted, and numerous large limbs were downed. Two electrical transmission line cross members were broken. The tornado crossed into McLean County near Jewel City. A swath of straight line winds accompanied the tornadic circulation across far eastern Webster County, far northern Hopkins County, and into southwestern McLean County.
Wind damage occurred along KY-370 from Ashbyburg to Jewel City on the northern inflow of a tornadic storm, primarily to large tree branches. Emergency management reported minor roof damage to a home along KY-370. An NWS Storm Survey found this damage to be from straight-line winds. Time estimated from radar.
An EF-0 tornado began southwest of Ashbyburg in Hopkins County, and tracked eastward, crossing into McLean County near Jewel City. The tornado dissipated shortly after damaging a few more trees off of KY-138. Estimated peak winds with the McLean County portion of the tornado were 80mph.
Several small, and a few large, tree branches were downed as a supercell pushed eastward near the Green River.
An NWS damage survey team found an EF-1 tornado, with peak winds of 95mph, occurred north of Livermore in McLean County. The tornado began near KY-138, causing significant loss of roof paneling to a barn. As it traveled a winding path generally eastward, extensive tree damage occurred along the path, including snapped tree trunks and uprooted trees. Two homes suffered significant damage when trees fell onto them. Other homes suffered shingle and fascia damage, and one had a detached garage collapse. A few power poles were damaged. The tornado lifted near the Ohio County line after damaging tree branches on Logsdon Ln.
Tree damage was reported north of Livermore on US-431 between Atherton and KY-1080. This damage is north of the surveyed tornado track.
A tree was blown down onto a structure in Livermore as a supercell storm moved through town.
A tree was blown down onto a vehicle and power lines were downed towards Island.
