EF1 tornado, Norton to Aultman, Ohio, April 7, 2020
From Norton to Aultman, this EF1 tornado ran 9.8 miles across Summit County on April 7, 2020, touching down at 11:52 PM EDT and reaching 100 yards wide. It killed nobody, and did $500,000 of property damage.
The rating scale
Tracks are drawn in the color of the rating. The Enhanced Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.
EF065 to 85 mph
Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
EF186 to 110 mphthis tornado
Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.
EF2111 to 135 mph
Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.
EF3136 to 165 mph
Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.
EF4166 to 200 mph
Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.
EF5over 200 mph
Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.
Unrated
The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

What the Weather Service recorded
A surface low moved from west-central Lower Michigan during the evening of April 7th to near Long Island by daybreak on April 8th. The accompanying cold front extended west-southwestward from the low and swept south-southeastward through northern Ohio during the early morning of the 8th. Along and ahead of the cold front, clusters of thunderstorms, including supercells, formed over southern Lake Michigan and southern Lower Michigan by the early evening of the 7th. These storms grew upscale into a squall line, which then moved generally southeastward through northern Ohio from late evening of the 7th through the first hour of the 8th. Additional more discrete thunderstorms, including supercells, developed ahead of the squall line. These storms encountered primarily moderate instability amidst strong effective bulk shear within the warm sector. In addition to numerous reports of damaging straight-line winds and severe hail, three QLCS tornadoes occurred within the squall line and affected portions of northeast Ohio.
An EF1 tornado began at a baseball diamond complex along Yonkers Road, about 0.25 miles northwest of Newton Park in Barberton. As the tornado moved southeastward through Barberton, softwood trees were uprooted between Morgan Street and West Summit Street, just west of Orchard Ave, and along Grandview Ave, just northwest of the intersection with 5th Street NE. Farther to the southeast in Barberton, the tornado uprooted several hardwood trees which then fell onto and damaged three homes along Wisteria Drive. As the tornado progressed through the Portage Lakes area, at least 200 trees were lost in the Bramblewood Estates, between Quail Ridge Circle and OH 619. Nearby, softwood and hardwood trees were either snapped or uprooted at and near Turkeyfoot Lake Golf Links. The tornado then entered Green, where hardwood trees were uprooted along Arlington Road, about 0.10 miles south of Harring Road, and along Golden Wood Way, where a tree fell onto a garage and caused extensive damage to the home. Farther to the southeast, the tornado snapped multiple softwood trees at a cemetery along Thursby Road and peeled away portions of a barn's roof along Thursby Road, just south of Greensburg Road. Soon thereafter, the tornado dissipated at the intersection of Thursby Road and Discovery Road. No fatalities or injuries occurred.

What this means
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.
