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 tornado touched down near a property along 110th Ave, uprooting multiple trees. The tornado tracked north toward County Road E, snapping tree trunks along the way. It then started to track more to the northeast, destroying a farm outbuilding along with multiple uprooted trees at a property along 160th Street. The debris from this outbuilding was found along the rest of the tornado track. The most substantial damage occurred at a property along 165th Street, where multiple trees were snapped and a silo sustained significant damage. The silo was shifted, had one side caved in, and had its top removed. After this, the tornado tracked north of 140th Avenue before roping out and dissipating before reaching County Road G.
