What EF2 means. On the Enhanced Fujita scale, EF2 is considerable damage: roofs torn off well-built houses, mobile homes destroyed, large trees snapped or uprooted, consistent with estimated gusts of 111–135 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

A house and mobile home were destoyed north of Tomah and another house was significantly damaged northeast of Tomah.

The wider storm

During the afternoon of May 22nd, severe thunderstorms developed along a cold front as it moved through western Wisconsin. These severe thunderstorms produced three confirmed tornadoes, two of which were rated as EF2 with the other being an EF1. The first tornado hit the southern sections of the city of La Crosse (La Crosse County) and caused an estimated 15 million dollars in damage where almost 200 buildings were damaged including 9 homes that were destroyed. The second tornado tracked from extreme eastern La Crosse County into Monroe County passing through the southern portions of Sparta (Monroe County). Considerable damage occurred in Sparta with a local car dealership sustaining damage to vehicles on the sales lot. The third tornado was on the ground for almost 65 miles as it tracked from eastern Monroe County, across northern Juneau County, through southern Wood County and into Portage County before dissipating. Damage estimates for this tornado in Monroe and Juneau Counties are close to 6 million dollars with most of this occurring in Juneau County where a cranberry farm was severely damaged.
