| Brief Description: EVENT NARRATIVE: Based on an eyewitness report, a tornado touched in the backyard of a home just west of Interstate 39, on the eastern edge of a subdivision. The tornado then blew over a school bus near the intersection of Argyle and Harlem Roads. There were six people on the bus, the driver and five children. All six people were taken to the hospital but none of the injuries were serious. The tornado then knocked down eleven electrical high tension towers just southwest of the same intersection. The tornado continued northeast into western Boone county, and moved across largely open rural fields towards the town of Caledonia. Significant damage occured to at least six buildings in Caledonia, with approximately 20 additional buildings sustaining minor damage. Several large trees were snapped or uprooted and a grain bin was partially collapsed. The tornado then continued northeast from Caledonia, downing several power poles, and causing damage ranging from blown off roofs to completely destroying at least three farm outbuildings. One of these buildings, located 2 miles northwest of Capron, had also been damaged during the January 2008 tornado. The tornado path, consisting mainly of sporadic tree damage at this point, then continued to a location roughly one mile west of Lawrence, where the tornado appears to have dissipated at 325 pm. EPISODE NARRATIVE: Strong to severe thunderstorms moved across parts of northern Illinois during the afternoon hours of November 22nd. These storms produced two tornadoes, hail, heavy rain and some flooding. | |||||||||||

| 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 3 miles northeast of Capron. The first signs of damage were at Quail Trap Road just east of Popular Grove Road where trees were damaged and sections of roofing were removed from a shed. The tornado intensified to EF2 intensity at Edwards Apple Orchard on Centerville Road. A large barn was destroyed and other buildings were severely damaged. Large trees were snapped or uprooted. The tornado reached its maximum intensity of EF3 at the northeast corner of Centerville Road and Beaverton Road. A two story farm house and garage were leveled and large trees were stripped of all branches. The tornado was about 100 yards wide through this area. The tornado continued east northeast across Stimes Road and eventually crossed the Boone McHenry County line near Hunter Road. Most of the damage through this part of the tornado path was EF1, though it weakened to EF0 near the county line. There was damage to trees, power lines, barns and sheds. A few farm houses had shingles or small sections of roof damaged. Four injuries were reported. 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. | |||||||||||

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

| Brief Description: EVENT NARRATIVE: This tornado in western Kenosha County was a continuation of the tornado that spun up 2.27 mils NE of Pell Lake in southeastern Walworth County. It crossed into Kenosha County about 0.4 mile north of where CTH U in Walworth County crosses the county line and becomes CTH F in Walworth County. The tornado continued northeast to just east of the intersection of STH 50 and CTH O, crossed STH 83 just north of 51st Street just north of New Munster Creek, passed through the Village of Wheatland, turned more east and crossed 308th Ave. just north of Peterson Creek, and then dissipated near a pond between CTH PH and 41st Street (Town Rd). Fifteen people in the Civil Town of Wheatland sustained minor injuries. Also in the Civil Town of Wheatland, 7 homes were affected, 25 sustained minor damage, 27 had major damage, and 25 were destroyed. In the Civil Town of Brighton, 10 homes were affected, 3 had minor damage, 3 had major damage, and 4 were destroyed. About 160 people were homeless due to residential damage. This tornado traveled over frozen ponds and creeks, as well as snow piles leftover from recent snowmelt. Average path width was about 100 yards. The wind speed was estimated at 150 to 160 mph (DI 2 - FR12, DOD 8). For a couple homes, the visual damage suggested an EF4 rating, however insufficient anchoring allowed these structures to fail at a lower wind speed. Additionally, other nearby damage indicators didn't support an EF4 rating. The specific starting location in Kenosha County was 42.556342,-88.30533, and the ending location was 42.60061,-88.13524. For plotting purposes, here are a couple mid-point locations of this tornadoe's path: crossing of STH 83 - 42.59297, -88.22230, and the crossing of CTH B - 42.59756, -88.15928. EPISODE NARRATIVE: Very rare, mid-winter, severe storms affected parts of south-central and southeast Wisconsin on January 7th - in the form of two tornadoes and scattered, large, hailstones, and downburst winds. The last time a tornado occurred in January in Wisconsin was on the 24th in 1967 in Green and Rock Counties (25-mile track). On January 7th, a low pressure moved northeast through western Wisconsin, allowing a warm front to push through southern Wisconsin. Temperatures rose into the lower to mid 60s over southeast Wisconsin with surface dewpoints peaking in the mid to upper 50s, resulting in moderate amounts of instablity. Strong, veering winds from the surface to the jet stream level generated sufficient wind shear that supported rotating updrafts in scattered supercell thunderstorms over southeast Wisconsin. A supercell thunderstorm, that had spun up a tornado in northeastern Illinois previously, then crossed the state line into south-central Walworth County (southeast of the city of Walworth) where it intesified and eventually spun up a tornado near Pell Lake that traveled into western Kenosha County. Another supercell spun up a tornado over the northern reaches of the city of Kensoha. Other scattered thunderstorms on this day across south-central and southeast Wisconsin dumped large hail up to 3/4 inch in diameter. | |||||||||||
