The rating scale

Tracks are drawn in the color of the rating. The Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.

  1. F040 to 72 mphthis tornado

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. F173 to 112 mph

    Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

  3. F2113 to 157 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. F3158 to 206 mph

    Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.

  5. F4207 to 260 mph

    Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

  6. F5261 to 318 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 significant severe weather episode occurred across north Texas during the evening hours of May 8th. Severe thunderstorms developed between Abilene and Childress along a dryline late in the afternoon and moved east into north Texas. The most severe weather occurred along a corridor roughly along and 40 miles to the south of US 380 from west of Throckmorton in Throckmorton County eastward to Greenville in Hunt County. Occasionally propagating in a train echo fashion, these storms were efficient hail and wind producers. Wise County was hardest hit by severe weather on the 8th, with wind, hail, and one confirmed tornado destroying 15 houses and damaging 178 others. Widespread damage to automobiles and trees also were reported. In Denton County, thunderstorm winds blew down powerlines across Interstate 35-E near Lake Dallas, closing both northbound and southbound lanes of traffic. In the ensuing traffic jam, motorists were stranded in their vehicles as another severe thunderstorm moved across the area. In all, damage from this severe weather episode was estimated at between $30 and $40 million, with damage in Wise County estimated at $5 million and $3 to $5 million in Denton County.

A tornado touched down at Bay Landing, a private RV park on the southeast side of Lake Bridgeport along US 380. Fifteen campers and recreation vehicles were damaged or destroyed.

The warnings

11 minutes of warning. NWS FWD issued a tornado warning for this county at 01:20 UTC, 11 minutes before the tornado touched down, in force until 01:45 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 Moderate Risk. The outlook in force was issued at 10:46 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.
