 Brief Description: The tornado entered Pope County near where Illinois Route 145 crosses the Massac County line. The tornado passed near the communities of Temple Hill, Homberg, and Brownfield. In Pope County, three mobile homes and four permanent homes were destroyed, along with numerous barns and outbuildings. An additional nine single-family homes and two mobile homes received major damage. Dozens of other residences received minor to moderate damage. Some vehicles were rolled or moved. The tornado passed just west and northwest of Golconda before ending about a mile north of town. Just west of Golconda, the roof was blown off the county elementary school's gymnasium. Despite the seven destroyed residences, not one injury was reported. The maximum intensity of the tornado was rated F-3 in Pope County, and F-4 in Massac and Pulaski Counties. The slightly lower intensity of the tornado, combined with the fact it narrowly missed the center of several Pope County communities, may partly explain the lack of injuries. When the tornado ended just north of Golconda, it had been on the ground for 33 miles and an hour and ten minutes. Where the track of the tornado ended near Golconda, the Ohio River and Kentucky state line were less than a mile away. The deadliest and most destructive storm of the night tracked within 10 miles of the Ohio River across extreme southern Illinois. The storm produced a 33-mile long tornado that killed two and injured about 33. A small but very damaging downburst occurred several miles south of the tornado track. A swath of large hail occurred north of the tornado track. Hailstones up to 2 inches in diameter were reported at and near the intersection of Highways 145 and 147, near the community of Glendale in Pope County.

 Brief Description: The tornado was near its maximum F-4 intensity as it crossed the Pulaski County line into western Massac County near the community of Hillerman. Estimated winds of 210 MPH disintegrated mobile homes and levelled several modern frame homes. One frame house was swept clean off its foundation, with only the roof left intact in a creek about 200 yards away. Many vehicles were lifted, rolled, or thrown up to 100 yards or more. Numerous cases of missiling were observed, including glass embedded in trees. Tree destruction in forested areas was nearly complete, and a few trees were debarked. The only fatality in Massac County was a 65-year-old female who was killed when her mobile home disintegrated. The official cause of death was blunt trauma to the head. She was found in a water-filled ravine about 100 yards from the former site of her mobile home. The frame of the mobile home was wrapped around the trunks of two trees that were stripped of all their limbs. Most of the levelled frame homes were concentrated on Boaz Road and Rolling Hills Road, in or near Hillerman. After passing through Hillerman, the tornado overturned dozens of railroad cars of a train just west of the Mermet Lake Conservation Area, which is off U.S. Route 45. The Mermet Lake Conservation Area was extensively damaged. An estimated 300 acres of forest were destroyed, boat docks were destroyed, and bathing facilities were destroyed. Dozens of waterfowl were found dead. After destroying additional residences and high tension power lines, the tornado crossed Interstate 24 near mile marker 28, about a mile south of the New Columbia exit. Tractor-trailer rigs and a tour bus were overturned on the interstate, injuring the drivers. The interstate was closed due to grain bins, tree limbs, and some building debris on the highway. Additional residences were destroyed between the interstate and the Pope County line. The tornado crossed into Pope County near where Illinois Route 145 crosses the county line. In Massac County, a total of 15 single-family houses and 13 mobile homes were destroyed. About 20 other single-family houses and 15 mobile homes received major damage. Several dozen other residences had some type of minor damage. Numerous vehicles and farming implements were destroyed, including combines. About 20 persons were injured in Massac County, but only one or two were hospitalized in serious or critical condition. Most of the injuries involved lacerations, bruises, broken bones, and internal injuries. Near Hillerman, a deputy sheriff escaped unhurt after his patrol car was thrown about 50 yards and struck by a flying tree and telephone pole. F65MH The deadliest and most destructive storm of the night tracked within 10 miles of the Ohio River across extreme southern Illinois. The storm produced a 33-mile long tornado that killed two and injured about 33. A small but very damaging downburst occurred several miles south of the tornado track. A swath of large hail occurred north of the tornado track. Hailstones up to 2 inches in diameter were reported at and near the intersection of Highways 145 and 147, near the community of Glendale in Pope County.

 Brief Description: EVENT NARRATIVE: Twenty-seven homes were damaged and 17 were destroyed. A total of 19 garages, sheds, and barns were damaged or destroyed. Of the destroyed homes, at least five were mobile homes. The two injured persons transported themselves to local hospitals. The county was declared a federal major disaster area. Peak winds were estimated near 130 mph. The average path width was 225 yards. EPISODE NARRATIVE: A deepening low pressure system moved northeast from Arkansas along a warm front that extended across southeast Missouri and southern Illinois. Surface dew points were in the upper 50's to lower 60's along and southeast of the warm front. A strong upper level trough over the western Plains produced a strong southwest flow of 60 to 80 knots at 500 mb. Winds at 850 mb were south to southwest around 40 knots.

 Brief Description: EVENT NARRATIVE: The highest concentrations of damage were where the tornado crossed State Route 1348 west of Crofton and Route 407 north of Crofton. Three unoccupied mobile homes were severely damaged or destroyed on Route 1348 west of Crofton. On Route 407, two mobile homes suffered moderate to major damage and a garage was levelled. The roof was peeled off one of the mobile homes. This tornado was very near the site of an EF3 tornado in Mannington just over a year earlier. One of the victims whose home was destroyed in the previous year's tornado relocated to a new spot, only to have her new home receive minor damage in this tornado. Several barns along the damage path received minor to moderate damage. Hundreds of trees were uprooted or snapped, particularly on Route 407 and nearby U.S. Highway 41. The tornado damage path began along Highway 109 and ended just after crossing the Pennyrile Parkway. The EF-2 tornado damage was near the end of the damage path along Route 407 and U.S. Highway 41, where hundreds of trees were uprooted or snapped. The average path width was 275 yards. Peak winds were estimated near 120 mph. The supercell that spawned this tornado later produced a separate brief tornado in Hopkins County. EPISODE NARRATIVE: A surface cold front extended from the Chicago area southwestward across the eastern fringes of the St. Louis metro area to a weak low pressure center over southeast Missouri. The low ejected northeast across southern and eastern Illinois, with the trailing cold front moving east across the Lower Ohio Valley. A broken cluster of severe thunderstorms, with embedded supercells and small bow echoes, moved east-northeastward across western Kentucky. Increasing south-southwesterly low level winds brought plenty of moisture northward into the Lower Ohio Valley, aiding in sufficient destabilization for supercells. The two primary supercells of the night followed similar paths across southern parts of the Purchase area, the Lakes region, and the southern Pennyrile region. Heavy rainfall with the storms, in combination with saturated ground from the May 1 storms, produced localized flash flooding.

 Brief Description: In Clay, 6 homes and 2 businesses were destroyed. An additional 45 homes and 4 businesses received varying degrees of damage, ranging from minor to major. A woman was injured when a tree fell and landed on her, breaking her hip. Peak winds were estimated near 125 MPH. One of the destroyed businesses was a hardware store. The other business, on the north side of Clay, housed spring planting supplies. That business lost four metal buildings. Numerous trees and power lines were blown down. A severe thunderstorm produced a series of tornadoes across Livingston, Crittenden, and Webster Counties. Both tornadoes in Livingston County originated on the Illinois side of the Ohio River. The strongest tornadoes occurred from Mattoon to Clay, where F2 damage was observed in spots.

 Brief Description: This tornado was produced by the same supercell thunderstorm that spawned a long-track tornado over southern Union and southwest Johnson Counties. This tornado touched down along U.S. Highway 45, about 3 miles south of Vienna. The tornado moved east across Interstate 24, and then dissipated about 1.5 miles east of the interstate near Ganntown. Two persons were injured when their mobile home was demolished. Two other mobile homes were extensively damaged. Numerous trees were down.

 Brief Description: EVENT NARRATIVE: This was the second and more intense of the tornadoes spawned by a supercell that tracked across Christian County. Near Mannington, a garage was destroyed, and a house was levelled. The main debris pile from the house was about 50 feet away. The 2,500 square-foot house was poorly anchored to the foundation. Two persons in the house were injured. One of the victims was thrown about 70 feet and suffered a broken pelvis. Footage of the tornado was taken by witnesses along the Pennyrile Parkway and shown on a local media outlet. Peak winds were estimated near 140 mph. The tornado tracked a short distance into Hopkins County before lifting. EPISODE NARRATIVE: A strong low pressure system tracked east to the Lower Ohio Valley, with a trailing cold front sweeping east across western Kentucky. Storms developed and increased along the advancing cold front as they moved into increasingly unstable air. Very strong low level wind shear was favorable for tornadoes. The storms became increasingly organized, with line segments and supercells moving at over 45 mph.

 Brief Description: The tornado formed from a long-track supercell that originated in southeast Missouri near Poplar Bluff. The tornado began less than two miles from the Trigg County line with an east-southeast movement, then curved slightly left before crossing Highway 91. The tornado moved east-northeast across central Christian County, passing less than four miles north of downtown Hopkinsville, before crossing into Todd County less than a mile north of Pilot Rock. Near the beginning of the damage path, a church was levelled. Across the county, 91 homes were destroyed, and another 171 homes sustained varying degrees of damage. Several people were pulled from the debris of their homes during a door-to-door search that lasted into the next morning. Of the 22 people directly injured by the tornado, 17 were checked in at the local hospital, and five were transferred to regional hospitals. Another ten or so people received injuries not directly inflicted by the tornado, such as driving into fallen trees. None of the injuries, which consisted mostly of cuts, bruises, and fractures, were considered life-threatening. Numerous garages, barns, and outbuildings were destroyed. Some vehicles were damaged or destroyed. Hundreds of trees were downed, snapped, or uprooted. Power was out to most of the city of Hopkinsville for about six hours as a result of downed steel towers that carry primary transmission lines. Peak winds were estimated near 185 MPH. The average path width was 500 yards. It should be noted that the initial tornado reformed or reorganized about 7 miles northeast of Hopkinsville, leaving a break in the tornado path less than a mile long. Downburst wind damage occurred both north and south of the area where the tornado reorganized, resulting in a two-mile wide swath of damage along Highway 107. The webcam at the local hospital captured the tornado as it passed north of downtown Hopkinsville.

 Brief Description: The tornado crossed into Ballard County between Wickliffe and the U.S. Route 60/62 bridge over the Ohio River. The tornado was rated F-2 in a forested area along the Mississippi River just north of Wickliffe, where intense tree damage was observed. Along the rest of its path through Ballard County, it was rated F-1 or F-0 (winds below 113 MPH). Where the tornado passed through the northeast outskirts of Wickliffe, there were a few homes with mainly minor damage. Roads were blocked by large fallen trees, including a 300-year-old white oak tree. The tornado moved east-southeast across rural Ballard County, where there was considerable roof damage to a home, and a garage door was blown out. Large trees were uprooted. At least one house was struck by falling trees. There was slight structural damage to the roof and attic portion of a home. The most prolific tornado-producing storm of the night entered western Kentucky near the confluence of the Ohio and Mississippi Rivers and moved east, passing between Paducah and Mayfield. The storm continued to spawn tornadoes, mostly of weak to moderate intensity, until it reached Kentucky Lake. Elsewhere, severe thunderstorms moved northeast across northwest Kentucky, producing sporadic wind damage and a tornado. Sporadic wind damage occurred in Livingston, Crittenden, Webster, and Daviess Counties, with a tornado in Union and Henderson Counties.

 Brief Description: This tornado entered Pope County from Johnson County in a remote area of the Shawnee National Forest. Most of the track was through heavily forested areas, causing extensive tree destruction. The tornado reached its peak intensity about a mile northeast of Bell Smith Springs, a scenic river gorge about 4 miles northwest of Eddyville. Peak winds were estimated near 120 MPH. Near the end of the damage path, just as the tornado was reaching Illinois Route 145, a mobile home was damaged. A supercell thunderstorm organized over southern Jackson County, then spawned a tornado as it moved east along the Union/Williamson County line. This supercell continued east-southeast across northern Johnson and northern Pope Counties, producing two significant tornadoes and large hail. Although the storm exhibited strong rotation as it continued east through Hardin County and across the Ohio River into Kentucky, no additional tornadoes were reported there.

 Brief Description: This violent tornado began near Grand Chain and reached its maximum intensity of 210 MPH as it neared the Massac County line. A 53-year-old man was killed when the chimney of his house collapsed on him. The man, who was in his basement, was protecting his son by lying on top of him when the collapse occurred. The son received broken bones. Their house was impaled by some nearby large trees that prevented it from being swept farther away. Along the Pulaski County portion of the tornado path, six single family homes and ten mobile homes were destroyed. Another ten single family homes and a mobile home had major damage. A few dozen other residences received some type of minor damage. A few dozen outbuildings, two businesses, and a campground were destroyed or had major damage. Approximately 13 persons were injured, but only a few of those required hospitalization. All roads in the damage area were impassable due to large numbers of trees and building debris on them. Many of the tornado victims in this county had no insurance on their residences. The area of most intense destruction was along Tick Ridge Road, a state road that follows a ridge above the Ohio River. M53PH The deadliest and most destructive storm of the night tracked within 10 miles of the Ohio River across extreme southern Illinois. The storm produced a 33-mile long tornado that killed two and injured about 33. A small but very damaging downburst occurred several miles south of the tornado track. A swath of large hail occurred north of the tornado track. Hailstones up to 2 inches in diameter were reported at and near the intersection of Highways 145 and 147, near the community of Glendale in Pope County.

 Brief Description: EVENT NARRATIVE: The tornado crossed into Hickman County from Fulton County on U.S. Highway 51 just north of Crutchfield. Peak winds in this area were estimated near 115 mph. The EF-2 tornado damaged or destroyed several pole barns along U.S. Highway 51. One barn was over 100 feet long and was anchored by telephone poles set in concrete. Most of the poles were snapped. A few poles were pulled up, with one thrown about 50 yards. A section of U.S. 51 was closed due to downed power poles and debris. Large trees were uprooted or snapped. There was minor house damage. As the tornado continued northeast across Kentucky Highway 1070 and a nearby road, three homes were damaged. One of the houses sustained damage to an outside wall, which was pushed in about three inches. The carport attached to that wall was blown away. A two-story garage was destroyed, along with other sheds and another carport. The other two houses sustained damage to garages and siding. Windows were blown out, and a section of roof was blown off one house. The maximum path width of about 600 yards was in this area. The average path width was closer to 300 yards. The tornado then weakened significantly and produced only minor tree damage until it dissipated about a mile southwest of Fulgham. EPISODE NARRATIVE: A surface cold front extended from the Chicago area southwestward across the eastern fringes of the St. Louis metro area to a weak low pressure center over southeast Missouri. The low ejected northeast across southern and eastern Illinois, with the trailing cold front moving east across the Lower Ohio Valley.
