EF0 tornado, Dexter, Kansas, March 30, 2016

This EF0 tornado ran 0.5 miles across Cowley County on March 30, 2016, touching down at 4:48 PM CDT and reaching 50 yards wide. It killed nobody.

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

1 damage points were recorded along this path by NWS ICT, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 75 mph.

  • Brief touchdown in open country. No damage was reported.

What the Weather Service recorded

A strong mid to upper-deck trough that was located over the Central Great Basin surged east/northeast across the Great Plains throughout the day and that night. This forced a dry line east across South-Central Kansas, where numerous severe thunderstorms developed that afternoon. The severe thunderstorms were prolific hail-producers. Hardest hit was Butler County, most notably in and around El Dorado, where hail that reached 3 inches in diameter bombed a location 1 mile south of El Dorado Lake. A 2-inch diameter hailstone landed 6 miles south southeast of El Dorado Lake. There were also several reports of golf ball-sized hail in Butler County, then in Montgomery County which was hit that evening. In Montgomery County, the largest hail, 2 inches in diameter, landed in Coffeyville early that evening.

There were multiple reports of a brief touchdown. The tornado had since lifted.

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

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 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 19:42 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.
