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

This tornado began along Parcher Road, just north of County Route 13, where the tornado caused significant damage to a barn on the east side of Bucyrus. As the tornado traveled east-southeastward, it uprooted and snapped numerous trees. Twelve homes sustained moderate damage and one home was destroyed by downed trees and the tornado itself. The tornado also damaged three silos at Sunrise Cooperative, Inc. before ending very soon thereafter on the west side of Crestline. This tornado had peak intensity of EF1 with estimated peak winds of 105 mph.

The wider storm

Northern Ohio remained in a very humid air mass and along the northwestern flank of the Bermuda-Azores subtropical surface high pressure ridge during the late morning of the 28th into the 29th before a cold front swept southeastward across the region during the late morning through early afternoon of the 29th. Behind the front, a secondary trough axis moved generally southward across northern OH during the afternoon through early evening before another ridge built from the Canadian Prairies and northern Great Plains during the rest of the 29th.

Ahead of the cold front, northern OH resided in an environment comprised of moderate to strong effective bulk shear and primarily moderate to strong MUCAPE. Along and ahead of the cold front, multiple rounds of multicell thunderstorms persisted generally eastward across northern OH. These storms produced sporadic straight-line convective wind damage in addition to a mesovortex-related tornado near Bucyrus, OH.

Began near North Robinson (40.8036, -82.9023).
