EF0 tornado, Ringgold, Nebraska, March 18, 2012

This EF0 tornado ran 5.3 miles across McPherson County on March 18, 2012, touching down at 9:39 PM CDT and reaching 20 yards wide. It killed nobody, and did $100,000 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.

What the Weather Service recorded

A large upper level trough of low pressure emerged onto the Central Plains on March 18th, 2012. Isolated severe thunderstorms developed during the evening hours, where one isolated severe thunderstorm produced several tornadoes from central Lincoln County north into eastern Cherry County. One of the tornadoes produced significant damage near North Platte, in central Lincoln County. Additional damage was reported north in southeast McPherson County in the Ringgold area.

A tornado touched down approximately five miles south southeast of Ringgold in McPherson County and tracked north and northwest before dissipating near the Ringgold church. Tornado damage included several large tree limbs broken off, cedar trees uprooted, a center pivot irrigation system twisted and overturned, damage to a church building and small storage building. The tornado was on the ground intermittently for four minutes.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

The warnings

11 minutes of warning. NWS LBF issued a tornado warning for this county at 02:28 UTC, 11 minutes before the tornado touched down, in force until 03:00 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 Slight Risk. The outlook in force was issued at 00:59 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.
