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

An EF0 tornado touched down in rural Ashland County near the intersection of U.S. Route 30 and State Route 511. Some hardwood trees at that location were either toppled or damage. The tornado then intensified to EF1 strength as it continued east northeast across open farmland. A farm wagon was tossed and destroyed by the tornado and a cow was thrown and sustained a broken leg. The tornado heavily damaged a home along State Route 60 about a third of a mile north of U.S. 30. The house lost about half of its roof and had a brick chimney toppled. Some windows were blown out and the house lost siding on all four sides. An adjacent car port was leveled and a large overhead door in a nearby garage was blown in. The 90 year old occupant of the house was not injured. After striking the house, the tornado weakened and eventually lifted just east of State Route 60. The damage path from this tornado was just over two miles in length.

The wider storm

A cold front moved across the Ohio Valley and southern Great Lakes on the afternoon of Sunday, November 5th, 2017. Unseasonably warm and humid air was in place across the region ahead of the front. The cold front gradually progressed across the Ohio Valley and thunderstorms initiated and swept east ahead of the front. The storms formed in a very strong wind field and allowed the storms to move very rapidly east at speeds of 60 to 80 mph. A large macroburst formed and swept east just south of Cleveland and produced winds in excess of 100 mph. The most concentrated damage stretched from southern Lorain County across Cuyahoga County and into northern Summit, northern Portage and southern Geauga Counties. A 105 mph thunderstorm wind gust was measured at Aurora in Portage County. In addition to the damaging winds, at least 13 tornados were reported. Three of the tornadoes reached EF2 intensity with eight EF1 tornadoes and two EF0 tornadoes. Tens of thousands of trees were downed by these storms and widespread power outages occurred. In the Cleveland area alone, over 100,000 electric customers lost power. It took several days for power to be completely restored. Dozens of homes, buildings and barns were damaged or destroyed by the tornadoes.

Began near Widowville (40.7853, -82.3035).
