EF1 tornado, Freemans Store to Edgar Spgs, Missouri, May 21, 2019

From Freemans Store to Edgar Spgs, this EF1 tornado ran 5.9 miles across Phelps County on May 21, 2019, touching down at 4:18 PM CDT and reaching 800 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 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

7 damage points were recorded along this path by NWS SGF, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 100 mph.

  • several large trees uprooted and snapped.
  • large trees snapped and uprooted
  • hundreds of trees uprooted and snapped in cyclonic movement
  • trees snapped crossing highway H

What the Weather Service recorded

Multiple rounds of storms producing heavy rainfall, severe winds, hail and tornadoes moved across the Missouri Ozarks from May 20th and into the early morning hours of May 24th as upper level disturbances interacted with a slow moving but powerful storm system over the central Plains. Tornadoes occurred with each round, with the strongest and most numerous tornadoes occurring during the late afternoon and evening of the 22nd. On the anniversary of the Joplin Tornado off 2011, another tornado, rated EF-3 struck the north side of Joplin. This storm system eventually produced subsequent tornadoes in Golden City, Eldon and Jefferson City. Unfortunately there were three fatalities as a result of the tornado in Golden City. The cumulative rainfall caused areas of flash flooding with some flooding lingering across the region. Some locations in southeastern Kansas and southwestern Missouri reported in excess of 8 inches of rainfall over the 72 hour period. .

A National Weather Service storm survey determined that an EF-1 tornado with maximum winds of 100 mph traveled along a 6 mile path. The tornado touched down just west of Highway 63 along State Route K. Several large trees were snapped and uprooted along Route K. The tornado then tracked to the northeast crossing Highway 63. Additionally, hundreds of trees were snapped and uprooted along county roads east of Highway 63 and reached a maximum width of 800 yards. The tornado then continued northeast where it crossed State Route H and snapped several more trees before lifting just northeast of Route H before the Phelps County and Dent County border. There were no fatalities or injuries associated with this tornado and damage was confined to trees.

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. One was issued for the county at another hour that day.

The county was under a tornado watch, issued at 20:11 UTC and running to 22:47 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 19:56 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.
