Damage from the storm over Scott, Morgan and rural Sangamon counties consisted of the snapping of power poles and major tree damage, either ripped up or uprooted. Numerous farm buildings (both Morton type buildings and barns) were damaged or destroyed, as were numerous grain bins. One mobile home was destroyed. This long track tornado moved into the city of Springfield before dissipating. The tornado crossed Interstate 72 near mile marker 92, around 8:20 PM. It entered the city of Springfield near Cockrell Lane and Constitution Drive, tracking to the east-northeast around 50 mph. The tornado was about 300 yards wide, and produced F2 damage to several businesses from Constitution Drive, through Parkway Pointe, to Veterans Parkway and Lindbergh Blvd. The tornado widened to about 0.4 mile wide as it continued to track east-northeast south of Wabash Avenue, between Veterans Parkway and Chatham Road. The tornado widened further, to just over 1/2 mile wide from Westchester Blvd to the village of Jerome. The damage was rated as F2 along Wabash Avenue, between Chatham Road and MacArthur Blvd. The tornado then weakened slightly, producing F1 damage, as it turned to the northeast, nearly parallel with the Norfolk Southern Railroad tracks. The damage path remained nearly 1/2 mile wide. The width of the tornado decreased to about 1/4 mile wide as it strengthened again, and turned to the north-northeast near Iles Park and in the vicinity of Oak and Myrtle Streets, between 6th and 9th Streets. The damage was rated as F2 in these locations, with roofs blown off of homes and businesses, and garages severely damaged.

| Brief Description: A tornado initially touched down in a farm field and overturned some irrigation equipment 3 miles east southeast of Sepo. Then it travelled to the northeast destroying a mobile home which was anchored, but the only thing left was the floor of the unit. The floor was wiped clean of all plumbing fixtures and walls with only a washing machine and water heater left on the floor. Most of the debris was deposited in the Illinois River about 50 yards away. A couple of three foot diameter trees were snapped off near the mobile home. Also, a nearby machine shed was destroyed and a motor home was rolled three times over the top of the damage and left upside down 30 feet from its original position. Just north of the mobile home, a concrete block pumping station was damaged. The roof was torn off, all of the windows broken out, and one wall was buckled. The tornado then moved across the Illinois River into Mason County. The tornado moved into the Baldwin Beach area, damaging three homes. From there the tornado, hopped and skipped along a northeasterly track, causing spotty damage to trees. The tornado finally lifted and dissipated 7 miles northeast of Buzzville in the Jake Wolf Memorial Fish Hatchery area. No injuries were reported and no damage estimate was available. | |||||||||||

| Brief Description: An eyewitness reported that the tornado touched down on the southwest side of Monticello and traveled to the north northeast across town. It blew down numerous trees near the golf course then destroyed a storage building. In this area the tornado intensified to F2 Intensity (wind speeds of 120 to 130 mph) taking the roof of a church completely off and blew it into the roof of a nearby 2 story apartment building. The apartment building suffered severe damage and has been deemed uninhabitable. A farm implement building/business, which was close to 200 feet in length, had roughly three quarters of the building destroyed. Damage for this building was estimated at nearly $2 million, as several combines inside were severely damaged or destroyed. Debris from the building was thrown into a nearby power substation, causing a complete power outage to the town of 5,000 residents as well as neighboring communities. The tornado appeared to have lifted off the ground and stayed at tree top level for the remainder of its life through the town producing F0 damage. Numerous trees had the tops broken off and several large trees were uprooted. Once outside of town it did touch down briefly once more, damaging the roof of one home and destroying several outbuildings and a garage of another homestead about a mile north northeast of town. In this location, several 2 inch by 6 inch pieces of lumber from one of the machine sheds had shot through patio doors into the home. No injuries were reported due to the tornado. Damage is estimated around $2.2 million. | |||||||||||

| 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. | |||||||||||
