EF0 tornado, Evans Arpt, Ohio, June 27, 2018

This EF0 tornado ran 0.5 miles across Jackson County on June 27, 2018, touching down at 8:50 PM EDT and reaching 30 yards wide. It killed nobody, and did $150,000 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.

The damage survey

5 damage points were recorded along this path by NWS RLX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 90 mph.

  • Likely touchdown point, with corn stalks pushed over.
  • 60 foot length of metal roofing material bent upwards. Overhead doors pushed out to rear of building
  • Single engine aircraft flipped over onto a car, blown about 30 feet. A second single engine aircraft suffered collapse landing gear and dragged about 60 feet.
  • Several tree trunks snapped.

Survey points are preliminary and are the raw material the published rating was built from. Source: NWS Damage Assessment Toolkit.

What the Weather Service recorded

Following on and off rain through the day on the 27th, a cold front pushed through during the evening with heavy rainfall leading to flooding. One low topped cell produced a concentrated damage path in Jackson County. This was determined to be a tornado through the combination of eyewitness videos and a NWS storm survey. There was no lightning in the cell.

An EF0 tornado, with a maximum estimated wind speed of 85 mph, touched down across the northern portion of James A. Rhodes Airport near Jackson. It damaged a hanger, including bending some of the metal roof and an overhead door. One single engine aircraft was pushed 30 feet and flipped onto a car, and another was pushed about 60 feet and suffered a landing gear collapse. Several large trees were also snapped. Several videos of the tornado were recorded by bystanders.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

The warnings

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

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 General Thunderstorms Risk. The outlook in force was issued at 19:45 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.
