Unrated tornado, Edgewood to Lexa, Arkansas, March 31, 2023

From Edgewood to Lexa, this Unrated tornado ran 2.8 miles across Phillips County on March 31, 2023, touching down at 7:03 PM CDT and reaching 100 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 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.

    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.

What the Weather Service recorded

A regional tornado outbreak occurred during the late afternoon of Friday, March 31, 2023, and continued into the early morning hours of Saturday, April 1, 2023. This outbreak covered portions of the Ohio Valley, and the Middle and Lower Mississippi Valleys, including a good portion of the Mid-South and stretching into the Tennessee Valley. On Friday, March 31, a surface low was located near La Crosse, WI, with a cold front stretching south into central/southwest Missouri, western Arkansas, and eastern Texas. Surface temperatures were mainly in the 70s to approaching 80 degrees with surface dewpoints in the lower to middle 60s, yielding Surface-Based CAPE (SBCAPE) values between 1500-2000 J/kg by Friday evening. Favorable upper-level divergence produced by the right entrance region of a 140-kt jet streak at 300 mb provided ample lift to produce strong to severe thunderstorms across the region. Directional and speed shear were impressive with 70-80 knots of Effective Bulk Shear present and 0-1 km Storm Relative Helicity values between 500-600 m2/s2, all more than enough for organized thunderstorms across the area. Discrete supercells started to develop across the Lower Mississippi Valley during the afternoon hours on March 31, 2023, eventually tracking into the Mid-South by late afternoon. The first supercell that developed in the Mid-South produced an EF-3 that caused major damage in Wynne, Arkansas. Tornadic supercells continued to produce significant tornado damage across the Mid-South into the early morning hours of April 1, 2023. The hardest hit areas besides Wynne, Arkansas included Covington, Tennessee, and McNairy County, Tennessee. Overall, 14 tornadoes occurred across the Mid-South along with several reports of wind damage and measured damaging wind speeds. Eighteen people in the Mid-South lost their lives in this outbreak.

A funnel cloud that moved over much of Phillips County touched down as a tornado briefly northwest of Lexa as it crossed Highway 1. An emergency manager along with several public spotters observed the tornado briefly touching down over open fields. No damage indicators were found and thus the tornado is rated as an EF-U. Nearby reports of damage were from straight-line winds that were associated with the same storm's rearflank downdraft. A special thanks goes out to Phillips County Emergency Management for their assistance during this survey.

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 High Risk, with a 0.30 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 19:54 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.
