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

Most of the damage in and around Piedmont appeared to be the result of strong straight-line winds - both inflow into the storm and strong winds within the mesocyclone. But local media (KOCO Ch. 5) showed video of and storm chasers observed a condensation funnel about 5 to 6 miles W of Piedmont. The tornado damaged a barn and downed several electric poles before crossing Northwest Highway near Banner Road. The tornado damaged several more barns before lifting 5 miles west of Piedmont.
