| 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: 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: 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: EVENT NARRATIVE: Very quickly after the tornado that hit Streator lifted, yet another tornado touched down over extreme northern Livingston county approximately one quarter mile south of the county line and about a half mile west of 1100 E Road. Shortly after touching down, this tornado caused severe damage to homes on 1100 E Road and destroyed a barn as well. There were also several large trees downed in this location. As the tornado continued eastward, it completely collapsed a metal truss high tension electrical tower and bent over several other metal truss electrical towers in its path, which is consistent with low end EF3 damage. At this time the tornado was moving through an extremely rural area, however there was also a lone hardwood tree in its path that was debarked, with only large de-leafed branches remaining. The tornado continued eastward crossing Illinois Route 170 just south of the LaSalle and Livingston county line where hardwood trees were snapped. Large trees were broken at a farm house and a machine shed and grain bins were destroyed. The tornado then moved eastward for several more miles downing multiple trees and resulting in some minor structural damage between 1700 E Road and 1800 E 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: EVENT NARRATIVE: The beginning of the Dwight tornado occurred about 6 miles west of Dwight and about a quarter mile south of IL Route 17. On N 2200 E Road, 0.3 miles south of IL Route 17, a farm house sustained damage to windows, siding, and shingles, with many trees uprooted or damaged. Outbuildings were also damaged. The tornado at this point was rated EF1, with a path width of 70 yards. Debris from this farm was spread 200 yards wide across the field at N 2300E Road. The tornado proceeded to strike the golf course at N 2400 E Road, where numerous large trees were snapped and uprooted. Golf cart sheds were unroofed or severely damaged. At this point the tornado was rated low end EF2 with a path width of 300 yards. The tornado then moved east across Interstate 55 and moved into Dwight, damaging a lumber yard and other businesses. At Williams Street and old Route 66 a mobile home park was hit. Fourteen people were injured. One person who was seriously injured, later died. At the mobile home park, 35 mobile homes were destroyed. Damage here was rated EF2. Large trees were uprooted and power poles were snapped at the railroad tracks. At a ball field a little farther east, trees and fences were damaged and an announcer's booth was destroyed. Slightly farther east, there was minor damage to a church, but the church's garage was destroyed. There was damage to the high school auditorium roof and facade, and a greenhouse. A storage garage was destroyed at the high school. The tornado then continued east into a subdivision between Philmar Street and Prospect Avenue, where many large trees were downed on top of homes. At Sunset Drive and Wilmac Street a garage door and roof were taken off. A roof was taken off a house on Linden Street a half block west of Il Route 47. Three houses were uninhabitable and had to be destroyed. More than 100 homes had some damage. Damage in Dwight was rated high end EF1 to low end EF2. The tornado dissipated in an open field east of Route 47. EPISODE NARRATIVE: Severe thunderstorms, including a few long tracked supercells moved across central and northern Illinois, producing damaging winds, hail and tornadoes. | |||||||||||

| Brief Description: EVENT NARRATIVE: A tornado touched down in far northwest Kankakee County then crossed County Line Road into Will County north of Essex. Tree tops were sheared off at Essex and Cooper Roads. A clear path could be seen in the trees at McGuire Road. At Route 113 and Smiley Road near Custer Park, trees were snapped and uprooted. Across the Kankakee River, a two story house had its roof completely removed and there was extensive tree damage. The tornado reached EF2 intensity at this point. The tornado continued across Route 102 near Ritchie where trees were damaged. The tornado crossed old Chicago Road near Kahler Road where power lines were blown down, a shed and barn were damaged and there was minor damage to a house. Another shed was destroyed. The tornado weakened as it moved from Symerton and Kennedy Roads to Warner Bridge and Arsenal Roads. There was no damage except to one tree. There was minor damage to a barn and tree limbs north of Arsenal Road before the tornado dissipated. EPISODE NARRATIVE: A single supercell thunderstorm developed over western Illinois and moved northeast reaching Lake Michigan near the Illinois Indiana state line several hours later. This single thunderstorm produced eight different tornadoes as it moved east across Illinois. | |||||||||||
