Around 6:30 p.m. a tornado hit the town of Cambria, Wisconsin located in Columbia County. This was a very unusual storm as tornadoes weren't likely to occur.
It appears a possible outflow boundary moving northwest from earlier storms that occurred across Southeastern Wisconsin helped generate the tornado. These boundaries usually have vorticity associated with them and any storm that forms along this boundary under the right circumstances can produce a tornado.
Preliminary Reports and Video:
The National Weather Service conducted storm surveys and have rated the tornado an EF-1 on the enhanced fujita scale. For more information regarding the tornado click on their website.
