| 21:00Z | EF2 | KMKX | IL | Winnebago | Harlem | 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. |

This tornado moved northeast into southern Racine County across County Line Road, about 1,700 feet to the east of the intersection with 224th Avenue, and quickly intensified to EF-1 rating. A pole shed sustained minor roof and siding damage. Otherwise, damage was limited to mainly trees along the slightly more than 3/4 mile long path that averaged 75 yards wide. The EF0 estimated wind speed of 80 to 85 mph was based on DI 28(TS) DOD 4. The exact start location is Lat 42.66253 Lon -88.08841. The exact end location is Lat 42.66995 Lon -88.07447. |
| 22:02Z | EF1 | KMKX | WI | Racine | Union Grove | This tornado is a continuation of a segment that started in Kenosha County. It quickly intensified to an EF-1 rating after moving into Racine County. It moved into southern Racine County about 2.3 miles southwest of Union Grove, around 1,700 feet to the east of the intersection of County Line Road and 224th Avenue. The tornado moved northeast before dissipating near the intersection of County Highway K and County Highway H, about 1/2 mile southeast of Franksville. There were no fatalities, but 2 people were injured in storm-related vehicle accidents. Newspaper articles indicated they were hospitalized. Union Grove bore the brunt of the damage. Eleven buildings, fencing, and trees were damaged on the Racine County Fairgrounds. Large oak trees in Old Settler's Park, which is the northwest corner of the Racine County Fairgrounds, were hit hard. Across the street (STH 11), two businesses had large pieces of roof covering peeled off. One of these, Grove Gear, had about 10,000 square feet of it's roof ripped off, which allowed rain to damage the inside offices and equipment. Newspaper articles indicated that damage to Grove Gear alone was about $1.4 Million. Two other businesses also had roof and siding damage. A residential-care facility had several of its buildings damaged. Around 100 homes in the Village of Union Grove sustained light to moderate damage to roofs, windows, and/or siding, and numerous trees were either uprooted or had large branches broken or snapped. Numerous gas leaks in and around Union Grove were reported. Only one home was extensively damaged and had to be demolished. A semi-trailer truck overturned on Interstate 94 near State Highway 20, blocking the northbound lanes, as the tornado crossed the interstate. Another semi-trailer was blown over on eastbound Highway 20 near the west frontage road next to the interstate. A number of campers were overturned and one was destroyed at the Burlington RV store at the intersection of STH 20 and Interstate-94. WeEnergy Utility estimated that 3200 customers lost electrical power in Racine County. The path of the tornado averaged 75 yards in width. A detailed examination of the tornado path suggests that this tornado consisted of three or four individual vortices, with one taking over as the previous one dissipated. Each vortex had it own path, which resulted in segmented-appearance of the tornado path as shown in the associated image attached to this severe weather episode. Although the header strip for this tornado event indicates a path length of 10.57 miles, a manual map measurement value of 10.67 miles was obtained. The total loss estimate of $5M was received from Racine County Emergency Management. The EF1 estimated wind speed of 105 mph was based on DI 21(MBS) DOD 3. The exact start location is Lat 42.66995 Lon -88.07447. The exact end location is Lat 42.75586 Lon -87.90231. |
