| Brief Description: EVENT NARRATIVE: A tornado touched down just northeast of the Ridge Road and Cline Avenue intersection. Damage occurred at the Griffith Park Plaza Mall where windows were blown out of a row of stores and a portion of a roof was blown off of a vacant store. The damage path continued to the east, behind the mall. Two parked semi-trailers in the back of the mall were shifted eastward while a third was completely knocked over. The area to the east of this mall in the subdivision along and north of 37th Avenue near Lafayette Avenue and Rensselaer Avenue sustained some of the strongest wind damage from this tornado. Two houses on Lafayette Avenue had their roofs blown off with another house on Rensselaer Avenue also having its roof collapsed and a garage door pushed inward. Other significant damage that occurred was at the Habitat for Humanity storage building at Colfax and Ridge Road. Here, a cinder block storage building completely toppled to the ground. Although the building was knocked over, it appears as though the main cause of it faltering was due to a large tree that fell on top of it. At a nearby gas station within feet of this building, no damage occurred and people actually witnessed the tornado descend on the shelter. EPISODE NARRATIVE: A line of powerful thunderstorms moved across northwest Indiana during the evening hours of August 4th. These storms produced widespread and significant wind damage. | |||||||||||

| Brief Description: EVENT NARRATIVE: A tornado touched down at 330 pm CST about 1.2 miles north of Popular Grove in Boone County and ended at 348 pm about 3.2 miles north northeast of Harvard in McHenry County. The tornado crossed the Boone McHenry County line near Hunter Road, about 2.1 miles west northwest of Chemung. The tornado crossed Hunter Road into McHenry County and continued to track northeast across Ryan Road as an EF0 and caused mainly minor tree damage. It crossed White Oaks Road then it uprooted a hardwood tree and snapped off pine trees at their base along Maxon Road. This damage continued to be EF0 damage with winds estimated to 80 mph. The tornado intensified as it moved toward the town of Lawrence, where it produced the worst damage in McHenry County. Significant damage occurred in the town of Lawrence, particularly at a house that had more than half of its roof ripped off and garage blown down. The tornado then moved across the Chicago and Northwestern Railroad where it blew 12 railroad freight cars of the track. The train was moving at the time the tornado hit it, so as the main engine stopped, the remaining cars on the track continued along it and slammed into the front part of the train. This caused a few more cars to derail, including one containing hazardous materials that caused the evacuation of the town of Lawrence. The damage in Lawrence was rated as EF2 with winds up to 110 mph. As the tornado moved east of Lawrence it once again started to weaken with some tree damage and shingles off of a few houses on the northeast side of town. It then ran along Oak Grove Road for a stretch where it produced EF1 damage with a hardwood tree snapped at its base and knocked over an old, weakly structured barn. The tornado headed across farm fields and headed for Highway 14 where it damaged a metal barn and sheared a few trees. As it crossed Highway 14, it flipped a semi-trailer and injured the driver at a truck stop weigh station. It continued across Oak Grove Road where it lifted. The maximum width of the tornado in McHenry County was around 50 yards. EPISODE NARRATIVE: Severe thunderstorms developed ahead of a strong cold front across northern Illinois during the afternoon hours of January 7th. The storms moved southeast across east central Illinois during the early to mid evening hours. | |||||||||||
