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

A tornado formed in Montgomery County (WFO St. Louis CWA) and crossed into Christian County 4.4 miles southwest of Morrisonville. Just inside the Christian County line the tornado took the roof off of a shed and smashed it into the southwest corner of a house at the second level bedroom. A camper was tipped over on its side and a visible tornado track could be seen in the cornfield surrounding the house. A mile and a half northeast, a 16 foot wide garage door was completely removed and the west wall of the attached garage was removed as well. A carport on a nearby house was destroyed. Further up the road numerous power poles were blown down, a house was blown 3 inches to the west on its foundation, and another home sustained moderate damage from a fallen tree on one end and the attached garage frame was pushed 6 inches inward on the other end. Two inch diameter tree branches were pierced at least a foot into the ground in this area. About a mile further northeast, the tornado caused around $500,000 in damage to a farmstead. A garage was destroyed and wrapped around some farm equipment. More debris and missiles were projected several inches into the ground and a house was shifted a foot north from its foundation. Several outbuildings, grain bins, and two semis were destroyed. The tornado wrapped a grain bin around a combine and a huge grain wagon. The tornado remained on the ground for another mile and a half knocking over numerous trees and power poles before lifting and dissipating 4 miles north of Palmer. No injuries were reported and damage so far has been estimated around $750,000.

Began near Morrisonville (39.3700, -89.5200).
