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

This brief F1 tornado began a quarter of a mile north of Highway 152 on NS267 Road then moved east for a mile dissipating a half a mile south of Highway 152 on NS268 Road. The tornado launched a pickup camper 150 yards, snapped large tree limbs, and blew a cotton silo 50 yards. The tornado crossed Highway 152 and damaged a mobile home. The roof was peeled away to the north and exterior walls were removed with insulation blown around. It was still sitting on cinder blocks and it could not be determined by the survey team whether it was tied down. The mobile home appeared to be abandoned. Large tree limbs were downed towards the end of the path.

The wider storm

All of the tornadoes, nine total, that occurred on May 9, 2003 were produced by the same supercell. This thunderstorm developed in southwest Oklahoma along a retreating dryline. The storm moved northeast across Oklahoma eventually dissipating in northeastern Oklahoma. Most of the tornadoes occurred after dark. Three of the tornadoes affected western and northern portions of the Oklahoma City Metropolitan area making two days in a row (see May 8, 2003 data) that the Oklahoma City metro area was affected by a tornadic thunderstorm. The strongest tornado, an F3, moved across portions of the northeastern metro area. Large hail and strong straight-line winds associated with the rear-flank downdraft also occurred with this tornadic supercell. Other severe thunderstorms produced damaging large hail and strong winds across portions of Oklahoma.

Began near Binger (35.8833, -98.3167).
