| Brief Description: Rated very high end F2 The low topped supercell that produced 2 earlier tornadoes in Stark and Marshall/Bureau counties continued to be a cyclic tornado producer. The deadliest and longest lived tornado started at 1644 CST, 0.7 miles North Northeast of Florid in Putnam County and moved northeast toward Granville. The long lived nature of the tornado was due to it riding along a warm front pushing through Putnam and La Salle counties. Satellite imagery indicated a strengthening mesocyclone at 1625 CST (2225 Z) with the formation of a new line of feeder clouds into the supercell, and KDVN 88D velocity data showed a strengthening TVS signature by 1635 CST (2235 Z). Witnesses reported a multiple vortex tornado just prior to its arrival in Granville. The tornado hit Granville at 1647-1648 CST which coincided with the failure of the main power feed into town. The town was bisected by the half mile wide tornado with 12 buildings destroyed, 45 with major damage, and 26 with minor damage (mainly residential). The Granville State National Bank lost its roof and Hopkins Elementary School lost the roof over the old gymnasium with damage in nearly all the classrooms. Significant damage also occurred to Granville Drugs, the only drug store in town. In a strange twist of irony, the town had finally recovered from a major fire 4 years earlier that decimated much of the business district. The tornado continued northeast out of Granville and crossed over into La Salle County (WFO LOT) at 1653 CST (2253 Z), 3.8 miles Northeast of Granville. The Granville/Utica tornado was the first significant test of a new statewide mutual aid response agreement. In Granville 5 people were injured by the tornado, including an eldery female who suffered a heart attack during the tornado and was eventually Life Flighted to a Peoria hospital. Injuries were low due to the 32 minutes of lead time before the tornado struck Granville. Damage in Granville is estimated to be at least $8 million with the school suffering at least $3.5 million in damage. | |||||||||||

| Brief Description: The tornado entered LaSalle County from Putnam County, approximately 3 miles northeast of the town of Standard, producing F0 intensity damage in a wooded area southwest of Peru. As the tornado continued northeast, F2 intensity damage was done to several homes in a subdivision near the intersection of East 250th and 2569th Roads. Several roofs were blown off homes along with damage to external walls. Significant tree damage was done as well. Path width was estimated at 50 yards at this location. The tornado then continued northeast, crossing the Illinois River twice as it moved toward the town of Utica, downing a steel high tension tower on the north bank of the river, immediately west of Illinois 251. The tornado moved into the southwest side of Utica where it was F0 intensity. Homes along Washington Street only had tree and minor roof damage. A church steeple was damaged on Division between Johnson and Washington. Roofs and trees were more severely damaged on the south side of Johnson Street. The tornado rapidly increased to F3 intensity on the north side of Johnson Street where one home had its roof taken off and north walls blown out. A machinery building was completely destroyed on the south side of the canal and a semi-tractor trailer was blown into the canal. A large grain bin was blown across the canal and flattened. The tornado then moved north of the canal into the heart of town where several homes were severely damaged, garages were destroyed and brick buildings collapsed. Eight people died and seven were rescued from the basement of a turn of the century sandstone building at Clark and Church Streets. The tornado was approximately 250 yards wide at this point. On the east edge of the vortex along Mill Street, in downtown, buildings suffered damage to facades, roofs and windows. East of Mill Street there was damage to trees and minor roof damage. In the northeast section of town a mobile home was overturned on Grove, just east of Mill Street. The vortex crossed the railroad tracks and apparently dissipated on a steep bluff on the northeast side of town. At the top of the hill there were some trees and limbs down and some debris deposited.

| Brief Description: The tornado formed on the ridge northeast of Utica and moved across County Road 2803, west of 10th Street. A garage was destroyed and trees were damaged. The tornado became a wide multiple vortex tornado at this point. It caused damage to 2 homes, trees and outbuildings on Route 6, west of 11th Street. Part of the roof of a house was torn off. A storage building was damaged and a garage roof removed on 11th Street. A garage and grain bin were destroyed on County Road 2950. The tornado crossed I-80 at 12th Street damaging a building and flipping a semi-tractor trailer. The driver was not injured. North of I-80 a small satellite tornado formed behind the large parent tornado. It had a damage path 2 miles long and 5 to 20 yards wide. Its track was about 1/4 to 3/4 mile south of the main track. It caused no damage. The main tornado destroyed a machine shed on 13th Street and knocked down power poles. On 31st Street west of 14th big pine trees were snapped and a house suffered roof damage. A barn was destroyed on 14th north of 31st. On 32nd Street west of 15th, a two story house was hit. The top floor was mostly destroyed. A machine shed was destroyed on 16th between 32nd and 33rd. The tornado ended at 33rd and Route 23 where there was minor tree damage. | |||||||||||

| Brief Description: EVENT NARRATIVE: Shortly after the Magnolia, IL tornado lifted, the same supercell thunderstorm went on to produce another tornado near the Marshall and LaSalle County line. National Weather Service damage survey teams found the damage from this tornado began just west of 2900 E Road and about one quarter mile south of 1250 N Road, or N 12th Road, which is the road that marks the county line. The tornado crossed north of 1250 N Road at Interstate 39. See Stormdata for Illinois, Central for the beginning of this tornado. This tornado continued eastward tracking along and just north of 12th Road, producing primarily EF0 to EF1 intensity damage, largely in the form of downed trees, power lines, and very minor structural damage. After the tornado moved past E 9th Road, the damage became more sporadic, which corresponded with spotter and storm chasers who reported that the tornado was not continuously on the ground before it reached Streator. Damage became more consistent again as the tornado moved east of E 12th Road, remaining just north of N 12th Road. The tornado appears to have remained on the ground from this point east into the city of Streator. The damage from E 9th Road east to E 15th Road was rated EF0 intensity and consisted primarily of minor tree damage. The tornado appears to have intensified as it moved into the city of Streator with EF2 intensity damage near the Eagle Pass subdivision where there was significant tree damage, along with portions of roofs removed from well built single family homes. The tornado continued eastward across southern portions of the city of Streator, damaging numerous homes and completely destroying several homes. Some of the most intense damage in Streator occurred along Hall Street and near Southside Athletic Park, where damage was rated higher end EF2. The most intense damage occurred through an approximately one quarter mile wide path through the city of Streator. Twenty one homes were uninhabitable and had to be destroyed. Another 33 homes were uninhabitable and had to undergo major repair. Another 150 homes had some degree of damage. A few businesses were also damaged including the Engle Lane Theater, an auto salvage business, an auto repair shop, and a landscape and nursery business. The tornado then continued eastward out of the city of Streator producing additional EF0 to EF1 intensity damage just north of the Livingston and LaSalle county border. The tornado appears to have jogged slightly southward before lifting near the county line, just to the west of E 22nd Road. EPISODE NARRATIVE: Severe thunderstorms, including a few long tracked supercells moved across central and northern Illinois, producing damaging winds, hail and tornadoes. | |||||||||||

| Brief Description: The tornado touched down around 234 pm CDT approximately 1.75 miles north-northeast of Metamora in western Woodford County. The tornado traveled southeast for about 2.5 miles, before beginning a temporary eastward jog between county roads 1300E and 1400E. The tornado curved southeast again, striking the Parsons Company, Inc.'s manufacturing plant around 241 pm CDT. The plant was severely damaged by the tornado. Approximately 140 people were in the plant at the time, but all personnel made it to storm shelters in time (approximately 3 to 5 minutes before the tornado arrived). Steel beams and metal siding from the plant were found approximately three quarters of a mile east in a farm field. From the plant, the tornado continued east, just south of Illinois Route 116/117, affecting 4 farmsteads approximately 1/2 to 1 mile east of the plant. Two of the farmsteads closest to the plant (about 1/2 to 3/4 mile east) had the 2-story houses completely blown away, with only debris remaining in the basements and nearby property. The other two farmsteads had significant damage to the 2-story houses with outbuildings demolished. The center of the tornado tracked about 100 yards south of the houses located on the south side of the road. From the plant to the farmsteads, the average width of the tornado was 400 yards and was close to 1/4 mile wide at times. The greatest tornado intensity was during this approximately 1 mile stretch and has been rated F4 by the National Weather Service. At this point, the tornado began to move more east-southeast and caused significant damage to a barn near the intersection of County Roads 1300N and 1600E, about 2.5 miles southwest of Roanoke. The tornado continued to move east-southeast and damaged a house about 1.25 miles south-southwest of Roanoke, near the intersection of County Roads 1300N and 1700E. The tornado crossed 1300N shortly afterward and curved sharply to the southeast. The tornado lifted around 254 pm about 2 miles southeast of Roanoke, at County Road 1900E. | |||||||||||

| Brief Description: EVENT NARRATIVE: A tornado touched down 2.9 miles north of Washington in northern Tazewell County, then continued eastward to the Tazewell-Woodford County line. Numerous trees and power poles were snapped along the path of the tornado. Three large outbuildings and two hog sheds were destroyed. In addition, the roof of a farm house was lifted off, the roof of another house was severely damaged, a garage was destroyed, and a grain bin was blown one quarter of a mile into a field. The tornado then continued eastward into Woodford County. EPISODE NARRATIVE: A stationary frontal boundary extending from southern Michigan across north-central Illinois served as the focus for severe thunderstorm development during the late afternoon and evening of June 5th. A vigorous upper-level disturbance tracking across the Upper Midwest added extra wind energy to the atmosphere, allowing supercell thunderstorms to develop along the front. Eight tornadoes were spawned by the storms, mainly along a Galesburg to Eureka line. An isolated tornado formed further south across eastern Logan and western DeWitt counties as well. No injuries were reported. | |||||||||||
