   Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

2. EF186 to 110 mph

   Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

3. 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.

4. 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.

5. EF4166 to 200 mph

   Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

6. 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.

7. 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.

At the surface, an occluded low drifted from northeastern WI to the central Upper Peninsula of MI during the early afternoon through early evening of the 17th. Simultaneously, the low's attendant warm front drifted eastward across central Lake Erie and far-western PA, and the low's attendant cold front swept eastward from near the northwest OH/northeast IN border and central IN to near the OH/PA border, which caused the warm sector to shrink with time. Scattered multicell thunderstorms and a few supercell thunderstorms developed along and ahead of the cold front, and persisted generally eastward across northern OH as the storms encountered weak to moderate MUCAPE and DCAPE, respectively, and moderate to strong effective bulk shear. This environment allowed storms to produce damaging hail and straight-line convective wind gusts, respectively. Three tornadoes also occurred amidst favorably-low mixed layer lifting condensation levels less than 1500 meters AGL and favorably-strong, surface-based effective storm-relative helicity.

An EF0 tornado with estimated peak winds of 80 mph impacted portions of Southington and Champion Townships in Trumbull County. The tornado began near OH Route|305, east of Hoffman Norton Road. Damage in this location included significant damage to a garage and some downed trees and roofing damage, indicative of 80 mph tornadic winds. The tornado continued northeastward to Oak Hill Drive, where additional downed trees caused damage to a couple homes. The tornado continued northeastward to Downs Road NW, where more downed trees caused more home damage. The tornado moved farther northeastward and caused more tree damage west of Mahoning Avenue (OH Route 45), but the tornado dissipated before reaching the road.

19 minutes of warning. NWS CLE issued a tornado warning for this county at 22:42 UTC, 19 minutes before the tornado touched down, in force until 23:30 UTC.

The county was under a tornado watch, issued at 19:48 UTC and running to 00:17 UTC.

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 Slight Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 19:58 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

The radiosonde launches on either side of the tornado, from the nearest station that was launching then, drawn and analyzed the way Storm Lab does: the same diagram, the same parcel and shear definitions SPC's mesoanalysis uses.

The Cleveland radar (KCLE), 82 km away, was scanning. The volume nearest the touchdown began at 23:03 UTC.

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.
