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 single wide mobile home was demolished. The undercarriage was blown 100 yards. A father and his two adult sons, who were inside the home, were killed. Highway 77 was shut down in Diehlstadt. Numerous power lines were down. Several large warehouse buildings sustained partial roof loss and moderate structural damage. Several trees were snapped or uprooted. Propane leaks were reported. Fencing and signs were blown down. The tornado damage was on the eastern edge of a larger area of downburst wind damage. Peak winds were estimated near 115 mph.

The wider storm

Thunderstorms increased and spread southeast through the evening hours. Storm development was focused along and southwest of a frontal boundary that extended southeast from a weak surface low near St. Louis. A favorable combination of wind shear and instability near the boundary supported a few sustained severe storms with large hail, damaging winds, and a tornado.
