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

This tornado formed 4 miles southeast of Moorefield and tracked north for 4 miles before exiting Frontier County about 3 miles east northeast of Moorefield at 825 PM CST. The tornado continued into Lincoln County for another 13 miles before dissipating at 846 PM CST. As it touched down in Frontier County, it immediately hit a farmstead and took off the roof and attached garage on the house, collapsed a grain bin and carried a horse trailer across the road about 50 yards. The tornado continued north through fields overturning 3 pivot irrigation systems and several power poles before destroying a metal building on another farmstead. The tornado continued north across Highway 23 and traveled just west of one farmstead...breaking windows in the home and destroying a grain bin...and then east of another farmstead where it destroyed one small shed, took part of the roof off a hay barn, scattered irrigation pipe, destroyed a wind mill, and pulled a fence line out of the ground. Numerous trees were broken and uprooted along the path of the tornado. In Lincoln County, it continued to produce extensive damage at 2 more farmsteads. At one of these farmsteads, two adults were injured as their house was destroyed. The tornado was rated F2 in Frontier County and F3 in Lincoln County. The average path width in Frontier County was 220 yards.
