EF0 tornado, Wayne, Nebraska, May 12, 2023

This EF0 tornado ran 0.3 miles across Wayne County on May 12, 2023, touching down at 6:14 PM CDT and reaching 20 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

24 damage points were recorded along this path by NWS OAX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 93 mph.

  • Old barn with blown with wall blown out
  • Old shed that had the back corner blown out including part of the roof
  • Portion of fascia of south facing side of home removed
  • Branches blown out from tree line well into 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 strong low-pressure system which had been slowly moving east off the Rocky Mountains finally progressed into central Nebraska. This left eastern Nebraska in the warm sector as a warm front moved north into the area. The SPC issued an Enhanced Risk for severe weather with a 30% hatched for severe hail. There ended up being 19 confirmed tornadoes (3 EF2, 8 EF1, 4 EF0, 4 EFU). There were numerous hail reports the largest of which was 4.5 inches in Pawnee County. Another 4-inch report was received in Richardson County. Flash flooding was also observed in a few locations.

A tornado began in an open field and tracked across the east side of a farm, tipping a grain wagon, damaging trees, lifting an open shed, and damaging the roof of another shed. The debris was deposited up to 150 yards downstream where the track appeared to end in an open pasture prior to crossing 852nd road. Special thanks to Wayne County emergency management and Stanton County emergency management for assistance with the damage survey and drone-based evaluation.

A brief tornado uprooted and snapped trees at two farmsteads. The tree damage was in a narrow swath near the road while the other buildings and trees just to the west were largely untouched.

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

The warnings

28 minutes of warning. NWS OAX issued a tornado warning for this county at 22:46 UTC, 28 minutes before the tornado touched down, in force until 23:30 UTC.

The county was under a tornado watch, issued at 18:10 UTC and running to 02:00 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 0.10 chance of a tornado within 25 miles. The outlook in force was issued at 20:08 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.
