EF0 tornado, Mc Ewen to Few Chapel, Tennessee, March 2, 2020

From Mc Ewen to Few Chapel, this EF0 tornado ran 4.8 miles across Humphreys County on March 2, 2020, touching down at 11:42 PM CST and reaching 50 yards wide. It killed nobody, and did $25,000 of property damage.

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

25 damage points were recorded along this path by NWS OHX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 105 mph.

  • Hundreds of trees uprooted
  • Hundreds of trees downed and snapped. 250 yards
  • Roof blown off barn to the northwest landing in trees
  • Several dozen trees uprooted

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

From the late evening hours on March 2 into the early morning hours on March 3, supercell thunderstorms developed and spawned tornadoes across southeast Missouri, southern Kentucky, Tennessee, and central Alabama. One of these supercells formed near the Mississippi River in west Tennessee, then tracked eastward across the entire length of the state just north of the Interstate 40 corridor, spawning 10 tornadoes and dropping large hail bigger than the size of baseballs. Seven of these tornadoes touched down across Middle Tennessee, resulting in widespread damage, 307 injuries and 24 fatalities. An additional fatality and 2 more injuries occurred in Benton County in west Tennessee. These tornadoes were the worst seen in Tennessee since the devastating tornadoes of April 27, 2011 across east Tennessee, as well as the Super Tuesday tornadoes of February 5-6, 2008. Total damage estimates from the Tennessee Emergency Management Agency across Middle Tennessee reached $1.6 billion.

An EF-0 tornado touched down along Curtis Chapel Road just northwest of McEwen, where it damaged a small barn. The tornado continued eastward and damaged/uprooted some trees along CCC Road as well as caused some minor roof damage to a home. Additional damage was found on Tummins Road where a few trees were uprooted. The tornado appeared to dissipate shortly after that location.

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 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 01:02 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.
