   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.

   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.

A historic North Texas tornado outbreak occurred on April 3rd, with 17 tornadoes developing from the DFW Metroplex east to Hopkins County. An EF-3 tornado tore through the town of Forney, heavily damaging homes in the Diamond Creek subdivision. Three EF-2 tornadoes damaged parts of Arlington and Kennedale in Tarrant County; Red Oak, Lancaster, and Dallas in Ellis and Dallas counties; and Royse City in Rockwall and Hunt counties. An EF-1 tornado caused damage near Joshua in Johnson County, and the remaining 12 tornadoes were rated EF-0s. In addition to the tornadoes, large hail damaged many parts of the DFW Metroplex. Approximately 110 airplanes at DFW International Airport were damaged by the hail and taken out of service until repaired. No fatalities occurred and only 29 people were injured. Of the 29 injuries, only 3 were considered serious but everyone made a full recovery. The environmental set-up on this day consisted of a cut-off low over New Mexico with a front draped north-to-south across the western counties of the CWA. By mid to late morning, strong and severe storms developed along the front as a lobe of energy rotated into west Texas and forcing from this energy overspread the front. The atmosphere was already unstable and uncapped by this time. In addition, a Mesoscale Convective System in Oklahoma sent an outflow boundary south across the Red River. This outflow boundary moved south of the DFW Metroplex by the late morning hours, and isolated storms began to develop south of the outflow boundary but east of the front. As these storms moved north and crossed the outflow boundary, the low level rotation increased and the storms quickly became tornadic. All of the tornadic storms were tied to this outflow boundary as it retreated north as a warm front.

A very brief tornado touched down in open field near FM 3389 and CR 1170, south of Brashear.

Trained spotters and Sulphur Springs PD reported a tornado near Highway 19 North and Loop 301 on the north side of town. This tornado touched down in open country but did damage to a few power poles, power lines, and trees. The tornado was rated an EF-0 with maximum estimated winds near 85 mph. The total path length was around 0.6 miles long with a width of approximately 50 yards.

29 minutes of warning. NWS FWD issued a tornado warning for this county at 20:25 UTC, 29 minutes before the tornado touched down, in force until 21:15 UTC.

The county was under a tornado watch, issued at 17:10 UTC and running to 22:58 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 Storm Prediction Center had this point in a Slight Risk, with a 0.10 chance of a tornado within 25 miles. The outlook in force was issued at 19:59 UTC.

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.
