During the afternoon and evening of the 5th, as well as the morning and afternoon of the 6th, an outbreak of severe storms and a few tornadoes occurred across the ArkLaMiss region. There were a number of reports of hail, wind damage, and a few tornadoes across the region. One of the strongest storms moved east across Choctaw County Mississippi. This storm produced an EF1 tornado over the southwest portion of the county. This storm did minor to major damage to five houses, church and several mobile homes. Another strong storm produced an EF1 tornado across northern Noxubee County Mississippi. It had blown an abandoned church of its foundation, overturned a camper and flipped over an 18 wheeler which caused minor injuries. There was also some reports of flash flooding across the northern portion of the ArkLaMiss due to heavy rainfall.

This tornado touched down west of Brooksville. Numerous hardwood and softwood trees were snapped and uprooted along the path. An abandoned church was pushed off its blocks. Several hunting camp cabins were damaged and a tractor trailer was turned over with only one minor injury. A few homes were damaged when trees fell on them. Maximum winds with this tornado were 100 mph.

21 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.
