69 damage points were recorded along this path by NWS CLE, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF2. The highest wind the damage implies is 123 mph.

• Large snapped tree is west. Cornfield blown SW
• Numerous trees snapped an uprooted. House to the north of Snyder Rd had roof damage. Metal was wrapped around a mailbox. A piece of slate was lodged in the trunk of a tree.
• More trees snapped back here, solid steel flag pole bent over completely.
• Numerous trees snapped and uprotted, with debris everywhere. Several projectiles lodged into the ground.

A cold front moved into northwest Ohio the evening of Thursday, June 15. A weak surface low pressure developed along this front over southern Michigan earlier in the day and moved southeast across the western tip of Lake Erie during the evening. A warm front extended southeast of this low pressure along the western Lake Erie shoreline and then down towards central Ohio. Thunderstorms erupted along the cold front near Toledo just before 6:00 PM and moved southeast towards east-central Ohio over the coming hours. Enhanced vertical wind shear associated with the low pressure and warm front allowed storms to rotate amidst an unstable environment. A particularly intense supercell (rotating thunderstorm) developed near the Ohio/Michigan border just north of Toledo and tracked across parts of Lucas, Ottawa, Sandusky, Erie, Huron, Seneca, Richland, Ashland, and Wayne Counties. This supercell was responsible for nine tornadoes and numerous instances of large hail, with hail to at least the size of tennis balls reported near Toledo and multiple reports of hail to golf ball sized or larger as the storm continued southeast. Heavy rainfall from this supercell also produced flash flooding across Huron County. Storms gradually congealed into a line that produced some hail and straight-line convective wind damage into east central Ohio.

This tornado began about two miles south of Monroeville, near Townline Road 198 and Sand Hill Road, where trees were damaged. The tornado moved southeastward, damaged additional trees, and caused EF0 to EF1-level damage to two barns and outbuildings. The greatest damage from the tornado occurred in vicinity of Snyder Road and Peru Center Road. This is where several residences sustained EF1 to EF2-level damage and the tornado's estimated peak winds reached 115 mph. A piece of slate roofing was lifted off a building north of Snyder Road and impaled a tree to the southeast. An outbuilding was destroyed completely and material from this structure was lofted a quarter mile southeast into a residence before eventually settling into a tree line. About ten buildings in total sustained damage, including one residence that was shifted off its foundation.||Damage to additional trees and outbuildings occurred as the tornado persisted farther southeastward across Peru Center Road, toward Townline Road 131 and OH-61. As the tornado reached Hanville Corners Road and Townline Road 113, several outbuildings and silos were damaged heavily with twisted debris lofted in various directions. The tornado continued farther southeast toward OH-162 and Ridge Road, where it caused heavy damage to a barn before the tornado dissipated west of the village of North Fairfield.

An EF0 tornado with estimated peak winds of 80 mph impacted portions of Peru Township. The tornado began at the intersection of Hettle and Terry Roads, where a pine tree was uprooted and several large tree branches were snapped. This tornado dissipated after crossing Peru Center Road.

An EF0 tornado with estimated peak winds of 85 mph tracked southeastward from near the intersection of OH-61 and Hanville Corners Road toward the intersection of OH-162 and Walnut Road. The tornado snapped a pine tree and damaged several other trees during its brief lifespan just west of North Fairfield.

This tornado began in vicinity of New State Road and Townline Road 131, where it downed a deteriorated barn. The tornado continued southeast toward the village of North Fairfield, intensified, lifted a large portion of a roof off an outbuilding, and downed several trees on Hanville Corners Road. A power pole was separated from power lines with additional tree damage. The tornado entered North Fairfield and caused widespread tree and power line damage in the village. Some roofing material was lifted off residences and some trees fell onto homes. A large sign was ripped off the facade of a building and several light and power poles were leaning along Main Street (OH-162). Damage in the village was at the EF0 to EF1 level and this is where the tornado was widest along its path.||The tornado continued southeastward across Penn Road toward Old State Road and Olive Road, where a large area of snapped and shredded trees fell and additional damage occurred to several barns and outbuildings. The greatest damage occurred near the intersection of Old State Road and Townline Road 12, where the tornado's estimated peak winds reached 110 mph. Several large trees were snapped, a mobile home was damaged heavily, and three power poles were snapped at their bases. As the tornado persisted farther southeast toward Boughtonville Road, several silos were damaged heavily. Near Edwards Road and Boughtonville Road, several roofs were displaced from outbuildings and the second floor of a residence was damaged heavily. The tornado continued toward Greenwich Milan Townline Road, where a large swath of trees were snapped. Minor tree and power pole damage occurred near the intersection of US-224 and Greenwich Milan Townline Road, west of the village of Greenwich, just before the tornado dissipated.

An EF1 tornado with estimated peak winds of 105 mph exhibited deviant west-to-east motion in the Greenwich area. The tornado started in vicinity of Townline Road 12 and Edwards Road, where several softwood trees were snapped. The tornado struck a business, where it damaged an office, several silos, an outbuilding, and some equipment. The tornado followed Townline Road 12 east to Greenwich Milan Townline Road, where additional tree damage occurred along with a clear damage path in a field. Additional trees were downed along Omega Road before the tornado dissipated near OH-13, northeast of Greenwich.

35 minutes of warning. NWS CLE issued a tornado warning for this county at 23:38 UTC, 35 minutes before the tornado touched down, in force until 00:15 UTC.

The county was under a severe thunderstorm watch, issued at 23:17 UTC and running to 02:37 UTC.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. 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 Marginal Risk. The outlook in force was issued at 19:57 UTC.

31 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.
