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

Tornado touched down 1.2 miles northwest of the intersection of Silvers Road and Highway C. The tornado traveled to the southeast. About half a mile west northwest of the intersection of Silvers Road and Highway C, a large outbuilding was destroyed, numerous trees snapped off and a house sustained moderate window, roof and siding damage. On the south side of Silvers road, a mobile home just had a few shingles blown off, but a small shed on the backside of mobile home was destroyed. Just a little further east and southeast, there was a convergent pattern in the corn field and a couple of power poles were snapped. The tornado crossed Highway C about a third of a mile south of the intersection of Highway C and Silvers Road. In this location, on the east side of the highway, a house sustained considerable damage. Most of the roof was removed, but the walls remained standing. Also, several power poles were snapped off along Highway C. Just north of the house, a large shed was destroyed and numerous trees were snapped off. The tornado then began to take a more easterly track. Just sporadic tree damage was observed along this section, as well as a couple of power poles that were leaning. The tornado then lifted and dissipated one mile east southeast of the intersection of Highway C and Silvers Road. Overall, the tornado was rated EF2 with a path length of 2.26 miles and a max path width of 400 yards.
