EF1 tornado, Pleasant Vly to Mulberry Corners, Ohio, August 6, 2024
From Pleasant Vly to Mulberry Corners, this EF1 tornado ran 4.7 miles across Lake and Geauga counties on August 6, 2024, touching down at 4:31 PM EDT and reaching 200 yards wide. It killed nobody, and did $30,000 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.

The damage survey
19 damage points were recorded along this path by NWS CLE, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 104 mph.
- Extensive tree damage on homes and cars.
- Tree damage in Bedford cemetary intermittent.
- Lots of branches just south of this intersection, looked like there was a lot of trees downed in the forests to the east of this road
- Start point of tornado, multiple snapped pine trees and all jumbled up, several snapped at the midway point

What the Weather Service recorded
Between about daybreak and nightfall on August 6th, a wavy surface cold front drifted generally southward from northern OH and near the NY/PA line to southern OH and the northern Mid-Atlantic states. This front separated a warm and humid air mass to its north from a warmer and more-humid air mass to its south. A line of multicell thunderstorms persisted southeastward across Mahoning County during the early afternoon and produced localized straight-line convective wind damage. During the late afternoon through early evening, a line of multicell thunderstorms moving eastward across northwest OH merged with a separate line of multicell thunderstorms moving southeastward across western and central Lake Erie. These lines merged to form a more-extensive QLCS that persisted southward and eastward across northern OH. Ahead of these storms, additional multicells and a few transient supercells developed in northeast OH. ||All of these storms occurred amidst weak to moderate MUCAPE and moderate to strong effective bulk shear. Extensive straight-line convective wind damage occurred in northern OH, especially northeast OH, as storms also encountered moderate DCAPE and steep low-level lapse rates. The QLCS also produced five mesovortex-related tornadoes amidst large surface-based ESRH of at least 150 meters squared per second squared and favorable mixed-layer LCL's less than 1k meters AGL.
This tornado had peak intensity of EF1, estimated peak winds of 110 mph, and travelled generally southeastward during its lifespan. The tornado began along Worrell Road, about two-miles south of Waite Hill, and caused tree damage before exiting Lake County and entering Geauga County just west-southwest of the intersection of Hidden Valley Drive and Tibbets Road on the northwest side of Chesterland.
This tornado had peak intensity of EF1, estimated peak winds of 110 mph, and travelled generally southeastward during its lifespan. The tornado exited Lake County and entered Geauga County just west-southwest of the intersection of Hidden Valley Drive and Tibbets Road on the northwest side of Chesterland. Numerous trees were uprooted and snapped along the Geauga County portion of the tornado's path, including along Tibbets and Caves Roads, Chillicothe Road, and Mulberry Road. Several homes experienced minor damage from the uprooted and snapped trees. The tornado then dissipated very soon after crossing Wilson Mills Road on the northeast side of Chesterland.

The forecast that day
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 19:55 UTC.

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.
