What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 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

The tornado touched down near Highway F and one quarter mile south of Jakes Prairie Road. Damage consisted of tree branches snapped. The next sign of damage was nearly two miles northeast of the first sign of damage, southwest of Four Mile Road and Brush Creek. There was some large tree limb damage west of the road along the creek. However a greater degree of tree damage occurred along Brush Creek east of Four Mile Road. This area of tree damage extended over 2 miles to the east-northeast. The width of the damage over this area was over 100 yards wide.

The next point of damage was on Highway 19, half a mile south of State Highway C. Minor tree damage was noted at this location. Tree limbs up to six inches were snapped half way up the tree trunk. The tornado traveled northeast and damaged one home and one farmstead on Taylor road. The owner of the house that was damaged described the tornado as a swirling rain, which confirms that the tornado was completely rain wrapped. The house suffered damage to the roof and patio. Several medium to large trees were snapped half way up the trunk to the west of the home, which is about 75 to 100 yards away. The tornado crossed Taylor road and damaged several trees on a hill north of Taylor Road. Some of these trees were snapped near the base of the trunk. The tornado then hit the first of two more farmsteads. Several panels from a barn's roof were peeled off, but the overall structure was intact. The roofs of three machine sheds were also removed and tossed to the northeast. The width of the damage area was approximately 75 yards wide.

The tornado skipped and caused minor damage to a barn and silo on a second farmstead on Ackermann Lane just south of Highway C. There were a few trees uprooted and large limbs were snapped over the upper parts of several medium size trees. Additional tops from trees were snapped a third of a mile southwest of Highways C and CC. The tornado then destroyed an evergreen tree along Highway C a quarter of a mile east of the intersection of Highways C and CC before lifting and dissipating.
