As multiple areas of low pressure rode along a strong cold front stretching across the Central United States and Ohio River Valley, the Storm Prediction Center issued an enhanced risk of severe weather on November 5 across parts of Illinois, Indiana, and Ohio.
This outlook included a 10% risk of tornadoes across the enhanced risk area.
Later that day, severe thunderstorm began to organize in a modestly unstable, highly sheared environment spanning from Missouri to New York, resulting in a multitude of hail and wind reports.
Rotating supercell thunderstorms developed across parts of the Ohio Valley late that afternoon and evening, and multiple tornadoes began touching down and causing damage.
Ohio sustained the most significant impacts during the event, with multiple towns sustaining direct hits from tornadoes, some of which were strong and destructive.
The first significant tornado of the event was a long-track, high-end EF2 wedge tornado that passed near the Indiana towns of Dunkirk and Portland before crossing into Ohio and dissipating west of Celina.
This damaging tornado heavily damaged or destroyed many homes and manufactured homes, destroyed numerous barns, garages, storage buildings, and outbuildings, damaged a church, an auto repair shop, and a gas plant, snapped numerous trees and power poles, and injured one person along its path.
A separate EF2 tornado struck Celina shortly after the initial tornado dissipated, blowing out windows and ripping the roofs off of businesses in town, heavily damaging a large factory building, snapping numerous trees and power poles, and injuring eight people.
An EF1 tornado caused considerable damage to sheds, trees, and homes in West Lodi, while another EF1 damaged trees, the roofs of homes, and a heavy equipment sales business in South Vienna.
One EF2 tornado struck Galion, tearing the roof off of a house, snapping trees, and severely damaging industrial buildings in town, while another brief EF2 obliterated a barn near Republic.

The town of Williamsfield sustained major impacts from an EF2 tornado, where frame homes sustained loss of roofs and exterior walls, and multiple mobile homes were completely destroyed.
An EF1 tornado also struck Calcutta, where trees were downed and air conditioning units were ripped from the roof of a YMCA.
Further to the east, an EF1 tornado moved through parts of Erie, Pennsylvania, damaging trees, homes, businesses, and a shopping plaza.
Tornadoes also struck towns in Indiana that afternoon and evening, including a brief EF1 tornado that damaged roofs and trees in Muncie, and another EF1 that damaged structures in downtown Salem.
In addition to the tornadoes, this severe weather outbreak produced multiple incidences of destructive straight-line winds, including 90-MPH thunderstorm winds that damaged restaurants, industrial buildings, businesses, mobile homes, and Findlay High School in Findlay, Ohio.
In northeastern Ohio, a large and powerful macroburst with winds of up to 105-MPH caused significant damage in numerous towns and communities throughout Lorain, Medina, Cuyahoga, Summit, Portage and Geauga counties.
These destructive winds shattered windows, stripped roofing and siding from homes, damaged a fire department communications tower, ripped the steeple off of a church, and downed countless trees and power poles across the affected area, with many landing on homes and vehicles.
A microburst containing 100-MPH winds also impacted Boardman, where businesses were damaged by the strong winds, and numerous homes were damaged by falling trees, some significantly.
With 16 tornadoes in Ohio alone, the November 5 outbreak marked the second-largest in state history for the month, behind only the Tornado outbreak of November 9–11, 2002.
Overall, this outbreak produced 24 tornadoes and did not result in any fatalities.
