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

Showers and thunderstorms affected the Ohio Valley during the afternoon and evening as a cold front moved through the region.

Based on aerial footage and photos, the tornado appeared to have initially touched down in a field just northwest of Dick Road. It then crossed Dick Road and produced damage on a farm. Some roof damage was noted on a single story residence on Dick Road, while a large outbuilding was also destroyed. Aerial footage confirmed evidence of the tornado in the grass and field between Dick Road and Mouser Road. Debris from the outbuilding was also scattered throughout the field between Dick Road and Mouser Road. Additional damage occurred on a property on Mouser Road, where two barns were completely destroyed. The tornado is believed to have then lifted shortly after it destroyed the barns. While the tornado ended before reaching U.S. 22, debris from the destroyed Mouser Road barns was thrown about one quarter of a mile and was noted on the other side of U.S. 22.||Based on the evaluation of the damage, winds associated with this brief tornado were around 85 mph.

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 19:53 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.
