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.

Trained storm spotters reported a tornado 6 miles northwest of Winnsboro which is also about 2 miles southeast of Pickton. The tornado damaged a few trees. Maximum wind speeds were likely around 80 mph.

25 minutes of warning. NWS FWD issued a tornado warning for this county at 22:11 UTC, 25 minutes before the tornado touched down, in force until 23:00 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.
