EF0 tornado in Seneca County, Ohio

A weak EF1 tornado touched down in rural Reed Township near the intersection of County Road 27 and Township Road 122. The tornado continued intermittently on the ground for about six miles before crossing into Huron County. Damage along the damage path consisted mainly of downed trees, although some structures did sustain significant damage. Several barns lost sections of roofing. One home near the initial touchdown had a second story wall partially collapse. The attached garage on one home lost its garage door and was lifted from its foundation. There was also evidence of extensive straight wind damage along the path. Crop damage, especially to corn, was significant.

A hot and humid airmass over the Ohio Valley was broken up on the 10th by a shortwave trough and a surface cold front that came moved through during the afternoon hours. Storms developed ahead of the cold front around noon, and ended with the exit of the cold front through northwest Pennsylvania around 7 pm. The humid and unstable airmass supported intense rainfall rates verified with reports of 0.75 in 15 minutes. These storms moved over an area that was already saturated from weeks of hit and miss storms and floods, and could not support the additional runoff produced during this event. The result was widespread flash flooding as the storms affected every county in the WFO Cleveland county warning area.

In addition to the flooding, widespread severe weather including three tornadoes occurred on July 10th. A line of intense thunderstorms developed ahead of the advancing cold front during the afternoon hours. Thunderstorm wind gusts in excess of 70 mph were reported. Seneca and Sandusky Counties in north central Ohio were especially hard hit. Thousands of downed trees and widespread power outages were reported. The Bellevue area was especially hard by the combination of straight line winds and a weak tornado. Nearly every street in the city had damage of some sort and it took five days for power to be restored to the majority of the city. Another tornado formed in northeastern Seneca County and moved in Huron County. A third tornado affected portions of rural Ashland County. Large swaths of corn were flattened across northern Ohio and nearly every county reported severe weather. As many as 250,000 electric customers lost power during this evening.
