Brief Description: A tornado touched down 1 mile southwest of Mattoon and travelled to the northeast. It damaged 4 homes in the initial touchdown area and then crossed a set of railroad tracks turning over 4 empty 30-ton coal cars. After crossing the railroad tracks, the tornado hit a self-storage facility, where six of the ten buildings in the complex were destroyed. The tin and steel girder buildings were not bolted down to the cement slabs, so they were lifted up, "wadded up" into a big pile, and deposited downstream about 200 yards. Further to the northeast, it damaged or destroyed numerous homes and businesses before lifting. It remained aloft for several blocks, then touched down again, tearing off treetops and damaging several roofs in the area. It lifted again and touched down a final time about a block away. Damage in this area was to tree tops and roofs. Overall, the tornado was on the ground for 1.5 miles and it either damaged or destroyed 120 homes and businesses. Damage is estimated between $2.5 and $3 million. Two people sustained minor injuries and one 9 year old child was seriously injured when a picture frame blew off the wall, hit her in the back, and cut her, causing her left lung to partially collapse. | |||||||||||

Brief Description: A tornado formed just north of 700th Avenue in Effingham County, on the Effingham/Jasper County line. It produced minor tree and barn damage to a farm at this location, and tracked to the northeast. The tornado struck a mobile home just inside the Jasper County line, and completely destroyed the home. The debris was blown several hundred yards into a field, with the home's refrigerator blown 1/4 mile into a field. The debris from the mobile home struck an adjacent automobile, and crushed the roof. The car was also pushed about 15 feet in the direction of impact. The tornado continued northeast, causing significant tree damage, and minor damage to a few homes and outbuildings. | |||||||||||

Brief Description: A tornado touched down half a mile to the southwest of Ogden and travelled to the northeast right through the middle of the town. The tornado destroyed 68 homes, 12 businesses, 3 churches, the library, and a grade school. Once east of town, the tornado crossed I-74, where it killed a woman who was riding in a semi with her husband. The semi and trailer were picked up and rolled into a field. The woman, who had been in the sleeper portion, was thrown about 30 yards from the truck. She was killed instantly. After rolling the semi, the tornado damaged 2 more homes before lifting and dissipating 1 mile north northeast of Ogden. Back in Ogden the damage was variable. One house would have significant damage, when a nearby structure would only have minor damage. In addition to the destroyed homes and businesses, 128 homes and 8 businesses sustained major damage and 51 homes and 12 businesses had minor damage. With it's larger width, it appears that this tornado had multiple circulations within the parent tornado. Overall, one woman was killed and thirteen people were injured. No damage estimate was available yet. F55VE | |||||||||||
