The path length in Logan County was nearly 20 miles. EPISODE NARRATIVE: A vigorous upper-level disturbance in conjunction with a warm front lifting northward through central Illinois triggered strong to severe thunderstorms during the afternoon and evening of August 19th.

| 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.

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.

| Brief Description: EVENT NARRATIVE: A tornado touched down on the west side of Lake Petersburg at 12:37 PM CST, then tracked northeast over the lake and across Sunny Acres Road, before lifting southeast of the intersection of Tice Road and Illinois 123 at 12:40 PM CST.

EPISODE NARRATIVE: A strong cold front pushed across central Illinois on December 31st, triggering a line of strong to severe thunderstorms. Unseasonably warm and moist air ahead of the front aided in initial storm development, while a strong upper-level disturbance created a highly sheared environment. One of the resulting supercell thunderstorms produced an EF3 tornado that tracked across the Lake Petersburg area in Menard County, creating considerable damage. | |||||||||||

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: As the first tornado was weakening on the west side of Hallsville another more significant tornado developed on the east side of town. It quickly intensified to F2 intensity, destroying two homes and causing damage to several others. In one home, a family of four sought shelter in the hallway. They were briefly trapped after the walls collapsed around them, but only sustained minor injuries. The tornado maintained its intensity and traveled to the southeast towards the south side of Clinton. As it approached US 51 numerous homes and businesses were severely damaged. Seven businesses were destroyed. The tornado finally weakened and lifted one mile south of Lane. Numerous trees, power lines and power poles were blown down as well. No other injuries were reported. | |||||||||||

| Brief Description: EVENT NARRATIVE: A tornado crossed the Knox-Peoria County line 1.1 miles west of Elmwood, then continued southeastward through the town of Elmwood. Considerable structural damage occurred to 10 homes, 30 businesses and nearly two dozen vehicles in downtown Elmwood, amounting to approximately $85 million in damages. There was a total of about 80 people, some that were attending an outdoor festival in the downtown and some that were at a theater, that took shelter in the basement of the movie theater. As a result, there were no injuries. The tornado dissipated 1 mile east of Elmwood. 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. | |||||||||||

| Brief Description: EVENT NARRATIVE: The tornado crossed into Sangamon County from Morgan County at 151 PM CST, then continued northeastward through the town of Loami before lifting 1.5 miles northwest of Chatham at 208 PM CST. In Loami, 13 homes were destroyed and 19 homes were severely damaged. In addition, the tornado produced damage to several homes, farm machinery sheds, trees, and crops along the remainder of its path. Three people sustained minor injuries from flying or falling debris in Loami. EPISODE NARRATIVE: A vigorous upper-level disturbance in conjunction with a warm front lifting northward through central Illinois triggered strong to severe thunderstorms during the afternoon and evening of August 19th. Embedded supercells within a long line of storms produced enhanced wind damage and tornadoes. Seven tornadoes touched down on August 19th, affecting parts of Scott, Morgan, Sangamon, Logan, DeWitt, McLean, and Vermilion counties. The strongest tornado was rated as an EF3 by an NWS Storm Survey as it tracked across southern Logan County. Total damages to crops and property from the 7 tornadoes were estimated to be more than $25 Million. | |||||||||||
