NOAA recorded where this tornado touched down but not where it lifted, so it appears as a point. Other tornadoes recorded nearby that day are shown faint.

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 touched down in Barnhart and nearly destroyed two mobile homes and heavily damaged five homes in a subdivision. Power poles were snapped off near the track with nearby trees uprooted or snapped off at the base. As the tornado moved north-northeast, it crossed County Road M and traveled along Highways 61-67 damaging the roof of a modern one story brick building. Several other homes had roof damage and a car dealership reported broken automobile windows from debris. Before lifting, the tornado damaged five other homes near Kimmswick and one mobile home, but no injuries were reported.
