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 F0 means. This tornado was rated on Fujita’s original scale, used until 2007. F0 meant light damage: shingles and siding peeled, gutters torn, branches broken; the scale paired it with winds of 40–72 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

This short-lived tornado was observed by an off-duty National Weather Service meteorologist near mile marker 117 on Interstate 40 in Canadian County. A motorhome was blown over, and a highway sign was ripped off its post, consistent with an F0 rating.

The wider storm

Significant flash flooding and 6 tornadoes, mostly small, weak and short-lived, developed on the 22nd, across a 35 mile wide band from near Frederick in southwest Oklahoma northeastward to near Chandler in central Oklahoma. Rainfall amounts in this band averaged 4 to 8 inches. Anadarko in Caddo County, received 10 inches, which classifies as a 250-year rain event. Record-like flooding developed in some areas, particularly across southern Caddo and Grady Counties, from near Apache and Anadarko to near Chickasha.

Began near Calumet (35.5333, -98.0833).
