A complex of severe thunderstorms that tracked across portions of East Texas and Northwest Louisiana during the early morning hours of July 19th left behind a surface boundary which lifted north across Northeast Texas, Southeast Oklahoma, and Southwest Arkansas during the afternoon ahead of an approaching upper level shortwave trough. Strong heating near this surface boundary resulted in the development of moderate instability, with large scale forcing ahead of the approaching trough contributing to the development of a second round of severe thunderstorms during the late afternoon through the evening hours across portions of McCurtain County Oklahoma. These storms produced damaging winds which downed trees near Wright City and along the McCurtain County Oklahoma/Little River County Arkansas line, and produced large hail that fell in Idabel and near Broken Bow before moving into portions of Northeast Texas and Southwest Arkansas late in the afternoon. A brief, isolated tornado also touched down in the Haworth community.

An EF-1 tornado with maximum estimated winds near 90 mph touched down in Downtown Haworth. This tornado touched down on the west side of town near Choctaw Avenue and lifted just east of Elm Street along East 4th Street near the center of town. Most of the damage was to trees, but one uprooted tree fell on a home on West Arkansas Avenue and caused significant roof damage.

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 Enhanced Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 20:00 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.
