The path drawn at its surveyed width of 225 yards (0.13 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

A brief EF0 tornado with maximum winds of 85 MPH moved along a path with a maximum width of 225 yards for 1.29 miles across portions of Catoosa County. The tornado began as several trees were uprooted or snapped just east of Ooltewah-Ringgold Road between Sleepy Lane and Mountain Lane. The tornado traveled east northeast over White Oak Mountain continuing to cause damage to trees before ending just east of Cherokee Valley Road around Swallow Lane where several homes sustained damage. One home had its garage doors blown in and part of the garage roof lifted off. Debris from this roof was carried more than 500 yards away. Siding was pulled off of another home in this area. [11/30/16: Tornado #1, County #1/1, EF0, Catoosa, 2016:007].

The wider storm

A strong cold front associated with a deep and sharp upper-level trough swept through the state accompanied by a line of thunderstorms. Despite only marginal instability; ample deep-layer shear and a strong low-level jet resulted in several reports of damaging winds and tornadoes with these thunderstorms. The early morning hours tornado that occurred in Catoosa County was actually associated with a supercell. The other tornadoes were associated with a Quasi-Linear Convective System (QLCS) during the late morning/afternoon hours of the 30th.

Began near Copeland (34.9393, -85.1015).
