January 7, 2008 Tornadoes in Far Southeast Wisconsin
Experiencing a tornado in Wisconsin in January is extremely rare. In fact, it had only happened once between 1950 and 2007, when an F3 tornado affected parts of Green and Rock Counties on January 24, 1967. That tornado in South Central Wisconsin was part of a much larger outbreak of 30 tornadoes across mostly Iowa, Illinois and Missouri. Wisconsin ended up with 30 tornadoes in 1967. The 30-year average annual number of tornadoes in Wisconsin is 21.
However, on the afternoon of January 7, 2008 a warm, moist, and unstable airmass, with temperatures rising into the lower 60s, moved into Southeast Wisconsin - setting the stage for a rare January severe weather event. Thunderstorms formed just ahead of a stationary front and produced hail, damaging winds, and a few tornadoes.
One of the thunderstorms tracked from just north of Rockford, Illinois into far Southeast Wisconsin. This supercell thunderstorm produced an EF-3 tornado in Northern Illinois. For more, visit the NWS Chicago writeup. The same storm also produced two tornadoes in Wisconsin. The first tornado spun up in Southeast Walworth County and then tracked through the Wheatland and Brighton areas of Western Kenosha County. The second tornado occurred in the town of Somers and on the north side of the city of Kenosha.
Below is a map of the two tornado tracks across Walworth and Kenosha Counties:
In Walworth County, five structures sustained damage - three had minor damage and two had moderate damage. In Kenosha County, with both tornadoes combined, 105 homes sustained damage. 46 homes had minor damage, 32 had major damage and 27 were destroyed.
The tornado in the Wheatland area also marked the first confirmed tornado in Kenosha County since 2001 - a span of nearly 7 years! Also, Kenosha County had only seen 4 tornadoes between 1950 and 2007. The last tornado observed in Walworth County was in 2004.
The three tornadoes in Southeast Wisconsin and Northern Illinois were also part of a larger tornado outbreak on January 7th. The majority of the tornadoes occurred in Missouri, where 33 have been confirmed. In all, 48 tornadoes occurred spanning an area from Southeast Wisconsin through Eastern Oklahoma. A map depicting tornado tracks from the entire outbreak is depicted below.

After that, the tornado began to turn more to an easterly direction as it approached the Fox River near 45th Street. There was some damage to homes near the Fox River (click here for an aerial photo) and to some trees and homes further east (click here for an aerial photo). You can also see in the first photo the flooding on the Fox River.
The tornado continued to move to the east, eventually cutting through another small neighborhood near 301st Avenue and 49th Street and severely damaging several homes. The tornado damage path was extremely narrow here, but the damage was quite intense. Despite the narrow tornado path, it managed to strike one house squarely, leveling it.
