EF2 tornado, Elsey to Day, Missouri, May 22, 2011

From Elsey to Day, this EF2 tornado ran 15.7 miles across Stone and Taney counties on May 22, 2011, touching down at 7:10 PM CDT and reaching 200 yards wide. It killed nobody, and did $1.1 million 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 strong upper level trough across the central plains region and a strong upper level disturbance along with a frontal boundary in the area produced numerous severe storms with a few supercells across southeast Kansas. One cyclic supercell associated with the system produced a very large and deadly EF-5 tornado that hit the city of Joplin and then spawned two separate tornadoes that moved across southwestern Missouri. A separate tornadic supercell produced an EF-3 tornado that moved into McDonald County from Northeastern Oklahoma. ||Continuing thunderstorms lasted into May 23 as another line of thunderstorms moved across the region. This line of storms produced reports of large hail, damaging winds and a weak EF-0 tornado in south central Missouri. As the storms moved over the Joplin area, two police officers were struck by lightning while aiding in the post tornado efforts. One of the two officers later died of injuries from the lightning strike.

Tornado damage was first indicated on Cave Springs Road where trees were snapped and twisted. EF-0 damage was indicated at this point. The tornado then traveled east, partially damaging a mobile home and destroying another mobile home on Highway AA, near the intersection with Camp Clark Hill Road. Damage at this location was rated EF-1. Several turkey barns were then damaged along Horse Creek Road with EF-2 damaged noted. EF-0 damage to trees and a roof were noted along Johnson Rowe Road. EF-1 damage occurred along Bass Hollow Road where damage to a house and outbuildings occurred. This tornado continued into Taney County with maximum wind speeds estimated up to 120 mph at its peak and a maximum path width of 200 yards.

This is the continuation of the tornado that touched down in Stone County. The damage path continued across northeastern Taney County north of Reno Springs Road to just east of Highway 65 south of the community of Saddle Brooke. EF-1 damage was indicated to trees, outbuildings and a tower along its path in Taney County.

The forecast that day

The Storm Prediction Center had this point in a Moderate Risk, with a 0.10 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 20:00 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.
