| Brief Description: The tornado entered Perry County, IL from Randolph County about 1.5 miles south of Highway 154. The Perry County segment of the tornado was rated at its maximum intensity and width shortly after crossing the county line. Shortly after crossing into Perry County, some coal trucks were blown over, and a modular home was totally destroyed on Route 154 near Route 150. Two persons in the home were trapped inside for a time, but they sustained only minor injuries that were treated at a local hospital. Route 150 was closed for 12 hours due to downed trees and power lines. Within a few miles of the destroyed modular home, some hogs were killed at a hog farm, and an empty grain bin was picked up and blown 100 yards into a field. Several eyewitnesses at this location reported two funnels. As the tornado continued its northeast movement, passing northwest of Pinckneyville, it weakened to F1 intensity. Near where it crossed Illinois Route 13, trees were uprooted, roofs were blown off, and power poles were snapped. Siding was blown off a house. Near the end of the tornado track, just northwest of Tamaroa, a metal building was destroyed. Debris from the building was blown about 400 yards. A nearby house lost all of its shingles. Along the 20-mile path through Perry County, dozens of barns and outbuildings were severely damaged or destroyed. Dozens of homes sustained varying degrees of damage, ranging from minor to major. Hundreds of trees were uprooted or snapped. Peak winds on this county segment were estimated at 140 MPH, mainly near the Randolph County line. The average path width was close to 200 yards. A deputy sheriff reported a tornado crossing U.S. Highway 51 north of Tamaroa. This was the last evidence of the tornado, which likely dissipated as it crossed Route 51. | |||||||||||

Scores of trees were broken off or uprooted, and the roof was blown off a house. The tornado strengthened to F-3 intensity as it reached the junction of Highways P and C in Crosstown. The roof was torn off a church, windows were broken, and other structural damage occurred. Nearby, the roof was blown off a two-story brick store that was over 100 years old. An overturned vehicle was in the front yard, and trees were mangled. The width increased to 220 yards. In the center of Crosstown on Highway C, the tornado reached F-4 intensity. This is where a site-built house was levelled. The F-4 damage continued east along County Road 350 in Crosstown, where two more site-built houses were levelled. Only the bolted-down floor of one residence remained. An eyewitness along County Road 350 stated he took shelter in the basement after seeing fog coming directly toward him. His house remained mostly intact, except for the roof and garage. The tornado weakened to F-3 intensity about one to two miles east of Crosstown, where a modular home was destroyed except for the bathroom. A vehicle was tossed in the yard. The weakening trend continued east along County Road 350 to the Mississippi River, where many trees were uprooted and broken off. Some outbuildings were thrown around. The path width decreased to 75 yards as the intensity lowered to F-1. The average path width was 150 yards. There were five injuries requiring medical attention, including one broken arm.

| Brief Description: The tornado entered Perry County from Ste. Genevieve County near Highway NN and just west of the community of Giboney. The tornado moved northeast, crossing Interstate 55 only about one-half mile from the Ste. Genevieve County line. Two fatalities and F3 damage occurred in the vicinity of where the tornado crossed U.S. Route 61. The two fatalities occurred on U.S. 61, where a vehicle was picked up and thrown into a propane tank. The truck in which they were riding was likely picked up, flipped over, and slammed into the ground several times. The coroner stated that the victims died instantly. One of the victims was ejected from the truck, which then struck the top of a large propane tank. Because of the ensuing propane leak, the victim still in the truck could not be removed until the following day, when the propane was off-loaded from the tank. Both of the victims in the vehicle were residents of a mobile home who were trying to flee the tornado. The home from which they fled sustained only minor damage. At least four other people were significantly injured as they were picked up by tornadic winds and hurled 100 yards. Their injuries were compounded by wind-blown debris. Eight victims were admitted to a local hospital to remove debris which penetrated their bodies, and two others were sent to regional hospitals for serious injuries. Three mobile homes were flattened, a brick house had its roof and several walls blown off, and numerous vehicles were tossed around. A total of about a dozen residences were destroyed or severely damaged in Perry County. Perry County was designated a federal disaster area, enabling individual residents to apply for relief. The dashboard camera in a sheriff deputy's patrol car captured the tornado on film as it crossed U.S. 61 at F3 intensity. Peak winds were estimated near 170 MPH. The tornado crossed into Randolph County, Illinois at Old River, near some railroad tracks about 1.5 miles southeast of St. Marys. M40VE, F49VE | |||||||||||

| Brief Description: EVENT NARRATIVE: The tornado touched down just northeast of the intersection of North Green Mount Road and Lebanon Avenue in the Eagles Landing Subdivision, where up to 6 homes sustained minor to moderate damage. From this point the tornado produced a nearly continuous damage path that extended to about 1 mile southeast of the intersection of Highway 4 and Jefferson Road. It finally lifted as it approached the Kaskaskia River. The total path length of the tornado is estimated to be 12.8 miles, with an average width of damage of about one-tenth of a mile. However, straight line winds did cause lesser damage over a wider swath of up to 3 miles. The greatest damage was to a home located just west of the intersection of Highway 4 and Jefferson Road. Damage there was rated EF2 on the Enhanced Fujita Scale. Elsewhere along the path of the tornado, the damage was generally in the EF0-EF1 range. EPISODE NARRATIVE: A strong cold front moved through the region, triggering showers and thunderstorms. Numerous reports of large hail, a tornado and some wind damage occurred with these storms. | |||||||||||

The bulk of the damage and injuries occurred in a neighborhood on the southern half of the Lake of Egypt. The two injured persons were mobile home residents whose homes were demolished. One of the mobile homes was swept clean off its foundation. The demolished home was deposited 50 to 100 yards away. The 32-year-old male occupant of the mobile home, who was ejected from the home, received numerous bruises and cuts. A female resident of another mobile home was injured. In total, three mobile homes were destroyed, and dozens of mobile homes, barns, and sheds were damaged. Rescue efforts were hampered by a large amount of tree debris on roads. Peak winds in the Lake of Egypt neighborhood were estimated near 120 MPH. The tornado lifted as it reached the southeast side of the Lake of Egypt. The parent thunderstorm produced another tornado in northern Johnson County only a few miles beyond where this tornado lifted. 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: A tornado first caused damage along the west side of the town of Caseyville, Illinois along Forest Blvd, just east if Interstate 255. Over twelve witnesses observed the tornado along the leading edge of the bowing squall line as they saw debris tossed several hundred feet into the air. The tornado traveled east southeast along Forest Blvd and West Lincoln Avenue. Three house trailers were severely damaged by the tornado between 85th and Black Lane. Two injuries occurred in two of the three house trailers. Numerous large trees were severed or downed by the tornado. The roof of a large machine shed on Black Lane was uplifted and displaced several hundred yards to the east. The tornado then ripped through an auto salvage area where several vehicles were over-turned, damaged or destroyed. The width of this damage area was 50 to 100 yards wide while damage intensity was rated F1. The tornado continued to travel just a bit south of due east causing damage to two homes and a camper and completely destroying another mobile home. Some of the remains of the mobile home was observed 3/4 mile to the east just west of Highway 157. Pieces of metal were wrapped around snapped power poles while one 2 x 4 board was driven into the front windshield of a pickup truck. The width of this damage area varied from 50 to 75 yards while the damage intensity was rated low-end F2. The tornado continued east and showed a convergence pattern in a nearby wheat field south of West Lincoln Ave. The tornado then caused minor damage to six new homes 100 to 300 yards south of West Lincoln Ave and 1/4 to 1/2 mile west of Highway 159. Roofs from five homes were partially uplifted and tossed 200 to 400 yards downwind to the east. One home under construction was completely destroyed. The width of the damage area varied from 75 to 150 yards. The damage intensity was rated the lower end of F1. The tornado continued east up a ridge just east of Highway 157. Several large trees were snapped or uprooted just east of 157. Additional tree damage was found along Hill Road east of Highway 157. One home on Hill Road sustained minor roof damage. The tornado crossed East O'Fallon Drive and severed or uprooted several large trees. One home sustained minor roof damage while a machine shed and garage was severely damaged. The tornado damage track ended just west of Highway 159. Width of the damage area again varied from 75 to 100 yards while the damage intensity was rated at the lower end of F1. | |||||||||||

| Brief Description: Top winds were estimated near 130 MPH. Damage was relatively light due to the track of the tornado over rural portions of those counties. A few sheds and barns were destroyed, and a house sustained moderate damage. A fairly large metal barn, about 100 feet by 50 feet, was blown into a stand of trees, but remained fully intact in the upper reaches of the trees. Tree damage was complete along some wooded portions of the track. The tornado formed less than a half mile east of Thebes, and then tracked seven miles through the Shawnee National Forest. The damaged structures were near Thebes and Gale. | |||||||||||

| Brief Description: The thunderstorm which spawned the tornado from Cravat to Walnut Hill produced another twin/multiple vortex tornado from just northeast of Walnut Hill to the intersection of Interstate 57 and Illinois Route 161. The tornado moved through a heavily wooded area and destroyed several barns/farm implement buildings, one mobile home, and damaged several homes. The tornado narrowed in width, losing its twin characteristics as it approached the intersection of Interstate 57 and State Route 161. Six homes were damaged, one mobile home destroyed, and eleven barn/farm implement buildings were either damaged or completely destroyed. Two tractor trailers were overturned by the tornado near the intersection of I-57/161. | |||||||||||
