Multiple rounds of storms evolved over the region starting late on the 14th and lasted through the 15th. This produced several areas of heavy rainfall across the forecast area. The region that experienced the greatest rainfall was across Northeast Louisiana, and West Central Mississippi where 5 to 8 inches fell. The other area of heavy rain was along Interstate 20, through Central and East Central Mississippi. Here, 3 to 6 inches fell. All this heavy rain resulted in flash flooding across the area. The severe weather was more scattered in nature, but what did occur was mainly damaging winds and located across the southern half of the area.

This tornado began on the east side of Purvis, here it downed some limbs and small trees. The tornado intensified and widened at it approached and crossed Interstate 59 near Black Creek. Numerous trees and large limbs were snapped along the path as it moved through the area between the interstate and Highway 49. Additionally, a couple homes and outbuildings were damaged by limbs or trees falling on them. The tornado intensified again and narrowed as it approached Highway 49 and the south gate of Camp Shelby. A number of large trees were downed along the highway, and from there to the actual gate of Camp Shelby. One large tree fell on a mobile home on the east side of Highway 49, destroying it. Shingles were pulled off a couple commercial buildings along the highway as well and 2 power poles were snapped. This area was where the tornado reached its maximum intensity. As the tornado moved across Camp Shelby, it remained narrow, but not as intense, with winds likely in the 70 to 80 mph range. The tornado downed numerous large limbs and sporadic trees as it moved across the base. One large tree fell on base quarters home, causing serious damage to it, and another tree fell on a vehicle, destroying it. Some other minor roof damage was noted. The tornado continued causing sporadic tree damage as it crossed Highway 98 near the Perry County line where it dissipated. Maximum winds were around 105 mph. The total path length across Lamar and Forrest Counties was 15 miles.

This tornado occurred just south of the first, longer track tornado, and was on the ground for just over a mile. A concentrated path of trees, in a convergent pattern, was blown down. Additionally, half the roof of a small church was peeled off.

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 12:54 UTC.

13 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.
