A strong upper level storm system along with a surface dry line/front |over northeast Texas moved east during the evening hours of April 9th into the early morning hours of April 10th causing long lived supercell thunderstorms. These thunderstorms caused long track tornadoes to occur across southeast Oklahoma, southwest Arkansas, northeast Texas, and north Louisiana.

This storm developed about 100 yards inside the Morris County line, very near the Cass County line, about 5 miles northwest of Hughes Springs. This tornado first touched down just west of County Line Road near FM 130 in eastern Morris County, continuing east across CR 2865, before lifting near FM 250 north of FM 130. Numerous trees were uprooted and snapped, with power lines downed as well. This tornado was rated an EF1, with winds of around 90 mph.

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 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 19:48 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.
