What F1 means. This tornado was rated on Fujita’s original scale, used until 2007. F1 meant moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken; the scale paired it with winds of 73–112 mph, figures later judged too high, especially toward the top of the scale, and revised downward in the Enhanced Fujita scale. Ratings then, as now, came from the damage.

What the National Weather Service wrote

The tornado initially touched down just west of the intersection of Interstates 57 and 74. An animal hospital sustained minor damage to some free standing brick walls. Moving east northeast from this location, a semi was blown over on the clover leaf of the Interstate intersection. The driver did not sustain any injuries. To the east of the intersection, a fabrication business was destroyed with the entire building having collapsed and a 30 foot section of the front wall was pushed back towards the rear of the building. Two occupants of the business sustained minor injuries. One sustained a broken hand and numerous cuts and bruises and the other occupant had a minor bump on his head. Another building behind this business sustained major damage. The tornado then crossed a field into a small subdivision. A duplex sustained major damage when the western half of it was destroyed. Further down several homes sustained minor roof damage, with the exception of one home which had part of its roof ripped off. Numerous trees and several power lines were blown down as well. Damage was estimated around $500,000.
