East of Oregon the tornado tore through several farms before impacting residential subdivisions in Stoughton. One person was crushed to death in their basement from fireplace and chimney bricks that crashed through the floor. Numerous homes, businesses, farm buildings, vehicles, power-lines, trees, and other personal effects were either damaged or destroyed along its path that grew to a maximum width of about 600 yards north of Stoughton. As for residential structures, 220 sustained minor damage, 84 had major damage, and 69 were destroyed. As for business structures, 6 sustained minor damage, 1 had major damage, and 1 was destroyed. As for agricultural structures, 5 sustained minor damage, 5 had major damage, and 40 were destroyed. Several vehicles were flipped and tossed as well.[29] Some homes in town were completely leveled, and an F4 rating was considered. Further investigation revealed that the homes were not well-built, and the slow (sometimes nearly stationary) forward movement of the tornado negated a rating higher than F3. After striking Stoughton, the tornado caused damage to trees and crops north of Busseyville before dissipating. Debris from this tornado was lofted by the parent updraft and carried downstream to scattered locations in the counties of Jefferson, Waukesha, Milwaukee, Walworth, Racine, and Kenosha. 23 people were injured.[30][31]
Ten years later to the day, three tornadoes touched down outside of Lake Geneva, Big Bend, and Waukesha. There were no injuries or fatalities from those tornadoes.[32][33]
