EF2 tornado, Emerald to Lakeview, Nebraska, May 5, 2019

From Emerald to Lakeview, this EF2 tornado ran 0.6 miles across Lancaster County on May 5, 2019, touching down at 5:38 PM CDT and reaching 200 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 mph

    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 mphthis tornado

    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

18 damage points were recorded along this path by NWS OAX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF2. The highest wind the damage implies is 119 mph.

  • building not connected to slab
  • Dairy Sweet ice cream shop destroyed. Structure was slab on grade construction and was not anchored to foundation.
  • roof peeled back on Harley showroom.
  • tornadosen in video from storm chaser. Brief touchdown in a field.

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 cold front moving into the area triggered severe thunderstorms during the afternoon and evening on Sunday, May 5, 2019. Hail up to golf ball size occurred, wind gusts from 6o to 105 mph were reported, and 1 short lived EF2 occurred in Lincoln, NE.

Storm chaser video shows a brief tornado spin up in a field. EF scale is unknown.

A brief intense tornado vortex paralleled West Van Dorn St in Lincoln uprooting and snapping healthy trees along its path. The tornado hit a couple homes and produced roof damage. The tornado took a direct hit of an ice cream store and storage shed, flattening both. Damage was reported to the Lees Chicken restaurant. People were reported trapped inside for a brief period.

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

The warnings

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. The outlook in force was issued at 19:50 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.
