Early on the 5th, a strong storm system approached from the Plains. Ahead of the system, breezy southerly winds provided well above normal temperatures and abundant moisture. Warmth and moisture destabilized the atmosphere and fueled developing thunderstorms. A cold front moved across the state causing numerous severe storms and several tornadoes. One of the tornadoes tracked from Yell County to Sharp County, staying on the ground for 121.84 miles. This track length set a record for the longest tornado path ever recorded in Arkansas. The continuous track was confirmed by two National Weather Service meteorologists who flew the track with the Civil Air Patrol. The final track was based on ground surveys, the Civil Air Patrol flight, and an aerial mapping flight performed for the Arkansas Forestry Commission.

The tornado moved out of the Carden Bottoms area of Yell County, crossing the Arkansas River, and re-entering Pope County southwest of Atkins. The intensity and width of the tornado increased quickly within just a couple of miles after it moved across the Arkansas River. According to a survey by the Red Cross, damage included 46 houses destroyed, 19 houses with major damage, 37 houses with minor damage, and 2 other houses affected. In addition, 6 mobile homes were destroyed, 1 mobile home had major damage, and 4 others suffered minor damage. Several businesses were damaged as well. Numerous trees, power lines, and power poles were blown down. Several vehicles were blown off Interstate 40 as the tornado crossed the highway. One fatality occurred in the Lucky Landing area when a woman was thrown from her mobile home. Three fatalities, all members of a single family, occurred at a house on the east side of Atkins. Another fatality occurred in the Happy Bend community when a man left his mobile home and took shelter in a large, metal, intermodal shipping container. The container was blown hundreds of yards into the woods. The tornado then moved into Conway County, in the area west of Hattieville.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

16 minutes of warning. NWS LZK issued a tornado warning for this county at 22:33 UTC, 16 minutes before the tornado touched down, in force until 23:15 UTC.

The county was under a tornado watch, issued at 18:39 UTC and running to 02:00 UTC.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. 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 19:40 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.
