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

A large tornado touched down just north of Darouzett and the Oklahoma state line just before 9:30 PM. The tornado was spotted by several spotters during power flashes and lightning strikes. Several barns and outbuildings were destroyed with minimal damage to homes which were on the edge of the tornado. Numerous power poles and trees were snapped along the path which was over 500 yards at times. This tornado was rated EF-1 with an estimated maximum wind of 100 mph.

The wider storm

A powerful storm system brought significant severe weather to the region. Tornadoes, damaging winds, and large hail accompanied thunderstorms that formed during the afternoon hours and persisted into the evening. This was a very unusual event for late fall in the Central High Plains. One significant factor in this anomalous event was the presence of an unusual amount of moisture for mid-November, contributing to relatively high values of instability. Only one tornado had previously been documented in the Oklahoma Panhandle during the month of November.

Began near Logan (36.5114, -100.2813).
