Severe thunderstorms affected parts of Central and Southeast Arkansas during the afternoon of the 24th. Several isolated supercells moved across the region and produced tornadoes.

A strong tornado touched down in Drew County, about 4.5 miles north of Monticello. Damage along the track of the tornado consisted of downed trees onto a vehicle and mobile home. Windows were blown out of a house, a large metal shop building was destroyed, and a metal barn sustained major damage. The tornado continued moving to the northeast into Lincoln County.

A weak tornado touched down briefly in Drew County, southwest of the community of Selma. The only damage noted along the path of the tornado was a few dozen trees that were snapped off or uprooted.

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 Moderate Risk, with a 0.15 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 19:42 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

The radiosonde launches on either side of the tornado, from the nearest station that was launching then, drawn and analyzed the way Storm Lab does: the same diagram, the same parcel and shear definitions SPC's mesoanalysis uses.

The Little Rock radar (KLZK), 147 km away, was scanning. The volume nearest the touchdown began at 22:33 UTC.

17 more were confirmed in the United States that day.

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.
