EF0 tornado, Rivare to Wren, Indiana, May 30, 2008

From Rivare to Wren, this EF0 tornado ran 0.3 miles across Adams and Van Wert counties on May 30, 2008, touching down at 10:57 PM CDT and reaching 25 yards wide. It killed nobody, and did $61,000 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 moderately unstable, sheared environment was in place across northern Indiana ahead of a cold front. The atmosphere remained capped until the late afternoon and evening hours, when storms began to develop rapidly. Several storms south of a Monon, Indiana to Decatur, Indiana line became strong and even in some instances severe. A few storms exhibited rotation with one tornado confirmed in Wabash County.

A moderately unstable, sheared environment was in place across northwestern Ohio ahead of a cold front. The atmosphere remained capped until the evening hours, when storms began to develop rapidly with a few becoming severe. The severe storms were confined south of a Paulding to Leipsic line. A tornado touched down in the Glandorf area with other areas seeing straight-line wind damage.

A resident in Van Wert county Ohio observed a funnel touch down in an open field. Several trees were found blown down near the Adams County (IN) and Van Wert County (OH) line. A local clearing of corn stubble and debris was found. A shed at a nearby residence suffered some shingle damage. Damage was estimated at $500 for the shingle damage. The tornado moved into Van Wert county Ohio.

The tornado touched down near the Adams county, Indiana and Van Wert county, Ohio line. It proceeded across State Line Road and destroyed 2 closed, steel doors on a barn. The tornado dissipated over open field. Damage is estimated at $60,000 to the barn. No injuries were reported.

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

The warnings

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down. One was issued for the county at another hour that day.

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 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 00:53 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.
