EF1 tornado, Bellview to North Pleasureville, Kentucky, April 5, 2017

From Bellview to North Pleasureville, this EF1 tornado ran 1.7 miles across Henry County on April 5, 2017, touching down at 5:54 PM EDT and reaching 100 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.

  1. EF065 to 85 mph

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. EF186 to 110 mphthis tornado

    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

1 damage points were recorded along this path by NWS LMK, in the Damage Assessment Toolkit the survey teams carry. The highest wind the damage implies is 101 mph.

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

A strong area of low pressure tracked across the Ohio Valley on April 5. With an unseasonably warm and humid air mass in place, several lines of strong to severe thunderstorms developed across the area. This resulted in large hail and damaging winds across central Kentucky. There were also 4 tornadoes reported in central Kentucky.

The National Weather Service surveyed a small tornado path in Henry County. There were also areas of wind and hail damage along US 421. The first evidence of tornado damage was just south of US 421 where the tornado passed between two farms. Barns on either side of the path were damaged with the debris thrown clockwise which showed an anticyclonic rotation. Also, a nearby house���s siding was severely damaged by hail, with witnesses saying the hail was several inches deep. The tornado crossed US 421 and continued northeast. The last evidence of a tornado was at a house on Point Pleasant Road. The tornado blew in a garage door and caused siding damage again due to hail.

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.

The county was under a tornado watch, issued at 18:50 UTC and running to 23:52 UTC.

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, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 19:59 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.
