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 highly visible tornado developed about 8 miles southwest of Mangum, then moved northeast through the northwestern and northern portions of Mangum before dissipating about 3.5 miles north of Mangum just east of Oklahoma Highway 34. The beginning of the tornado path was in rural areas and the valley and terrain around the Salt Fork of the Red River and damage was mainly to trees. However as the tornado moved through the northwest side of Mangum and adjacent areas, many outbuildings were destroyed and at least one home just northwest of town had much of it's roof removed. The maximum damage in and near Mangum was consistent with an EF2 rating, although many indications (including research radar data from the Center for Severe Weather Research) indicate that the tornado was likely stronger in the rural areas southwest of Mangum.
