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.

A weak tornado touched downed in a field in rural Adams Township. The initial touchdown occurred east of County Road 21 about half way between Township Road 138 and County Road 38. A few trees were snapped or uprooted near the initial touchdown. The tornado then continued east as it rapidly strengthened to EF2 intensity. The tornado leveled a large barn as it approached State Route 18. Debris from the barn was found scattered across a large area including wrapped around utility poles and trees. The tornado crossed State Route 18 and lifted before reaching Township Road 183. This tornado was on the ground for just over a half mile.

A weak tornado touched down along Township Road 100 in West Lodi. The location is about 100 yards west of County Road 27. Two storage sheds near the initial touchdown were destroyed and their contents thrown across the area. Debris from the sheds peppered the two houses associated with the sheds. Both homes had projectiles from the sheds sticking out of three of their four sides. Both houses also sustained major roof damage and were shifted off of their foundations. The tornado then continued northeast across County Road 27 and strengthened to EF1 intensity. A couple homes on the east side of Country Road 27 had windows blown out and suffered roof damage. Many trees in the area were also snapped or uprooted. The tornado then continued northeast across farm land before lifting as it approached Township Road 134. Portions of a corn field were flattened by the tornado. The damage path was just under a half mile in width and over 150 yards in width at time.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down. One was issued for the county at another hour that day.

The county was under a tornado watch, issued at 17:10 UTC and running to 22:31 UTC.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Enhanced Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 19:59 UTC.

The Cleveland radar (KCLE), 96 km away, was scanning. The volume nearest the touchdown began at 21:53 UTC.

23 more were confirmed in the United States that day.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
