EF0 tornado, Bevis to Milford, Ohio, April 8, 2020
From Bevis to Milford, this EF0 tornado ran 6.2 miles across Hamilton County on April 8, 2020, touching down at 10:22 PM EDT and reaching 300 yards wide. It killed nobody, and did $100,000 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 mphthis tornado
Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
EF186 to 110 mph
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
Thunderstorms developed ahead of an advancing cold front which moved east across the region.
The tornado first touched down in Colerain Township near Colerain Ave, where trees were reported knocked down along with minor damage to the YMCA Play Time Early Learning Center. The tornado continued east along or just north of Compton Road, uprooting trees. Further to the east, the tornado continued to produce tree damage and minor structural damage on Ranchill Drive, before moving into the center of Mt. Healthy. Numerous downed trees, leaning or broken transmission poles, and damage to several buildings marked the path of the tornado through Mt. Healthy following Compton Road. Tree and transmission pole damage continued east out of Mt. Healthy into Springfield Township. The tornado may have briefly become less organized before causing additional light structural damage and extensive tree damage from Winton Road through Hill Top Acres. Damage decreased quickly toward Ridgeview Drive, with the last sign of tornadic damage on Compton Road. The large number of snapped and uprooted trees with little to no leaves, snapped or leaning transmission poles, and minor structure damage led to a rating of EF-0 on the Enhanced Fujita Scale with winds around 85 MPH.
The tornado first touched down along Keller Road, and continued southeast to the 8000 block of Blome Road, where trees were reported down. Numerous trees were also knocked down at the intersection of Drake Road and Camargo Road. As the tornado moved southeast, it briefly lifted, before producing additional damage along properties on Given Road. Damage to trees and barns was observed, in addition to downed power poles on Given Road, just north of the intersection with Shawnee Run Road. Additional tree damage was noted on Alberly Road. The tornado is believed to have dissipated along Park Road, where a few trees were downed. Based on the damage, the tornado which impacted eastern Hamilton County in the Indian Hill area produced winds of around 85 mph.

The warnings
No tornado warning for this county appears in the archive as in force at the moment the tornado touched down. One was issued for the county at another hour that day.
The county was under a tornado watch, issued at 23:25 UTC and running to 03:41 UTC.
| Issued (UTC) | Expired | Product | Office |
|---|---|---|---|
| 23:25 UTC | 03:41 UTC | Tornado Watch | ILN |

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. 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 forecast that day
The Storm Prediction Center had this point in a Enhanced Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 01:04 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.

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.
