The path drawn at its surveyed width of 400 yards (0.23 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 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

This tornado initially developed in a neighborhood just northwest of Rock Creek Road and 12th Avenue NE, then it moved east-northeast leaving a sporadic track of damage across northeast Norman until it dissipated near Franklin Road between 96th Avenue NE and 108th Avenue NE. Most of the damage along the path was to trees. The damage along the path was generally EF0 damage (winds estimated at 60-70 mph), with EF1 damage confined to an area north of Tecumseh Road between 48th Avenue NE and 60th Avenue NE where a home and an outbuilding experienced significant roof damage and damage to trees was more significant.

The wider storm

Several discrete supercells formed off a dryline in the eastern parts of the panhandles in the late afternoon of the 2nd. These storms moved eastward through the evening, eventually congealing into a line before coming across central Oklahoma. QLCS tornadoes became a significant hazard at this point. After this round of storms made its way out of the area, scattered storms began to form from central Texas up into south western Oklahoma overnight, moving generally northeast into the early morning hours.

Began near Norman (35.2516, -97.4296).
