EF2 tornado, Pearson, Arkansas, March 10, 2010

This EF2 tornado ran 3.4 miles across Cleburne County on March 10, 2010, touching down at 9:09 PM CST and reaching 300 yards wide. It killed 1 person and injured 3, and did $250,000 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 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.

What the Weather Service recorded

A low pressure system passed by just to the north of Arkansas on the 10th, with a trailing cold front pushing south across the state. This cold front met up with sufficient Gulf moisture and instability to trigger thunderstorms during the afternoon and evening. Many of the storms dropped hail and a few produced tornadoes.

A home was destroyed on South Sawmill Road, and the three occupants in the home were thrown out into a field. A 79 year-old man lost his life. The man's wife, 75 years old, suffered serious injuries, as did their grandson, 23 years old. The washer, dryer, and water heater from the home were found about 750 feet away in some brush. A mobile home on the same property was destroyed. Six other homes received minor damage. Some trees and power lines were blown down. A motorist on Arkansas Highway 107 was injured when his pickup truck was blown off the road.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. 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 0.10 chance of a tornado within 25 miles. The outlook in force was issued at 01:31 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.
