Unrated tornado, Masterson to Mc Bride, Texas, March 30, 2020

From Masterson to Mc Bride, this Unrated tornado ran 3.5 miles across Carson County on March 30, 2020, touching down at 5:22 PM CDT and reaching 50 yards wide. It killed nobody.

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 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. Unratedthis tornado

    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

High-based thunderstorms developed across the west-central Texas Panhandle during the afternoon. As these thunderstorms moved east, they crossed a north-south oriented dryline, with cloud bases lowering considerably. Additionally, with winds out of the east present on the eastern side of the dryline, these storms moved into an environment with low-level shear profiles conducive for the development of tornadoes. Furthermore, the presence of the dryline allowed for the potential development of landspout tornadoes for any storms that were located directly on or very close to the dryline. Two tornadoes did occur, one in Carson County and a landspout tornado in Sherman County.

The tornado remained in open country grasslands, touching down approximately 10 miles north of Pantex, and lifting approximately 11 miles north northeast of Pantex. The tornado did no visible damage. Path details were estimated based on chaser|pictures/reports and radar. Since this tornado remained in the open country grasslands and did no visible damage, it was given a rating of EF-Unknown as well as an unknown estimated peak wind speed.

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

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 Marginal Risk. The outlook in force was issued at 19:58 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.
