EF0 tornado, Hoagland to Hillsboro, Ohio, July 27, 2014

From Hoagland to Hillsboro, this EF0 tornado ran 2.5 miles across Highland County on July 27, 2014, touching down at 8:39 PM EDT and reaching 1,300 yards wide. It killed nobody, and did $80,000 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.

  1. EF065 to 85 mphthis tornado

    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.

What the Weather Service recorded

Thunderstorms developed during the afternoon and evening hours ahead of an approaching cold front. Some of the storms produced damaging winds, large hail and isolated tornadoes.

The tornado touched down on a residential drive about a quarter mile north of SR 138, where it brought down a couple of large trees. It then continued southeast across a field and crossed SR 138 where it downed a large tree and other branches, snapped 3 pine trees several feet above the ground, peeled back part of a barn roof on both its east and west sides, and damaged some fencing. Isolated trees were snapped further southeast along the tornado's discontinuous path.||At a residence along Holladay Road, a large well-constructed barn had its cap blown from its roof and a small section of the roof's southeast corner was peeled back, exposing the inside. Large pine trees were snapped with large segments carried 50 to 60 yards downstream. A few small branches were blown onto a van and a car tire had a piece of bark completely impaled through it. A 100 foot TV tower was knocked down and the house sustained minor roof and fascia damage. A large well-constructed metal storage barn across the street had its front door ripped off and carried southeast.||Numerous large trees and branches were downed along Ervin Road, just north of a quarry. Further east along Ervin Road, the roof of a house had numerous shingles ripped off and a small section of its southeast corner was peeled back. Fascia on the north side of the garage was completely ripped off and a 100 foot TV tower was toppled along the south side of the house and garage. A small shed southwest of the house was completely destroyed with the damage strewn into the front yard. Another small shed south of the house was twisted off its foundation and moved a short distance. A short distance southeast of this residence was a trailer home that had its west wall and a portion of its south wall blown in, but most of the walls remained intact. An old wooden pole barn just southeast of the trailer home was completely destroyed.||A church along US 62 sustained very minor roof and fascia damage. The church sign was blown through a school bus window and the bus itself was pushed sideways several feet. Two very large picnic tables (each weighing over 500 pounds) were pushed a short distance into a van, causing minor damage to the van. Another heavy table that was located in front of the van was picked up and smashed into a wooden pavilion support post, snapping the post. Just southeast of the church, a residence along Green Road had several large trees knocked down. A large, unanchored shed with a lawn tractor inside was carried off its foundation and blown 200 feet eastward. Just to the east, a boat on a trailer was nudged a few feet southeast from where it was parked. Several large trees were knocked down a short distance further to the east, and this was where the tornado ended.

The warnings

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down.

The county was under a tornado watch, issued at 17:49 UTC and running to 01:00 UTC.

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 Slight Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 20:00 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.
