EF2 Tornado confirmed at Caledonia
The National Weather Service office in Chicago has confirmed that an EF2 tornado occurred Monday afternoon near Caledonia Illinois, northeast of the city of Rockford.
Meteorologists from the National Weather Service in Chicago surveyed the damage along the track of the tornado Tuesday afternoon. The tornado appeared to begin at 3:04 pm in far east central Winnebago county, one mile east of Rock Cut State Park and approximately one quarter mile southwest of the intersection of Argyle and Harlem Roads. A school bus was blown over by the storm near that intersection, and 6 people on board the bus received minor injuries. The tornado then knocked down eleven electrical high tension towers just southwest of the same intersection. The tornado then 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 3:23pm. Times are approximate based on radar and eye-witness reports.

Path length: 16.4 miles
Estimated Max winds: 135 mph
In addition to the above tornado, thunderstorm wind damage occurred near McFarland and Thomas Drive in Loves Park where shingles were blown off roofs and fascia was damaged on several houses.
