The path drawn at its surveyed width of 40 yards (0.02 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF0 means. On the Enhanced Fujita scale, EF0 is light damage: shingles and siding peeled, gutters torn, branches broken, consistent with estimated gusts of 65–85 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

Within the line of severe thunderstorms a brief tornado occurred near Princeton.

The wider storm

On the afternoon of November a dry line pushed through the area, bringing very strong westerly winds to portions of western and northwestern Missouri. Several locations reported winds up to 60 to 70 mph, unrelated to thunderstorms. The majority of the damage caused by these winds ere done to trees and power lines, although there were some outbuildings and other structural damage as a result of these synoptic straight line winds. Along and ahead of the dry line thunderstorms formed, and also created some minor wind damage.

Began near Princeton (40.4290, -93.5800).
