Several rounds of storms occurred on the 4th as a large trough approached the region. Initially several storms developed across northwest Oklahoma with large hail, with new storm development then occurring along and south of a warm front in central Oklahoma during the afternoon. These storms produced several tornadoes, along with hail and damaging wind gusts. Another round of storms moved in from the Texas panhandle during the evening of the 4th, bringing more tornadoes, hail, and wind. Localized flooding was also reported due to storms training over the same areas.

A media storm chaser observed a tornado estimated to be about 4 miles north-northeast of Roosevelt. No damage was reported.

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.
