12 damage points were recorded along this path by NWS JAN, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 105 mph.

• several structures dmg, trees and poles snapped. gas station canopy torn off.
• small wood frame home demolished. wood foundation remained in tact
• homes damaged by uprooted trees
• loss of portion of a roof and a wall fell over on building

Widespread severe weather occurred with a mix of damaging winds, hail and several tornadoes. The focus of the severe weather was across central and southern Mississippi. This event was driven by a potent disturbance that swung across the area during the midday and afternoon hours. As this strong feature dropped into the Lower Mississippi River Valley, a surface low rapidly deepened as it tracked across central Mississippi. The atmospheric response to this was for a rapid increase in winds aloft and higher low level moisture. This combination set the stage for an unstable environment that contained high levels of wind shear which supported and sustained tornado development.

This brief tornado touched down on Smith County Road 114 in western Smith County. It crossed Georgia Pacific Land and ended back on County Road 114 near Clear Creek. A few trees were downed along the path. The maximum estimated wind speed was 75mph.

The tornado began near Smith County Road 84, where some softwood trees were uprooted. It then tracked northeast into Sylvarena. Here the tornado damaged several structures along Highway 18, including ripping off a gas station canopy and blowing down an antenna. Homes also had roof damage and were damaged by uprooted trees. The tornado continued northeast and lifted amongst some trees south of Ted-Sylvarena Road. The maximum estimated wind speed was 105mph.

44 minutes of warning. NWS JAN issued a tornado warning for this county at 18:40 UTC, 44 minutes before the tornado touched down, in force until 19:45 UTC.

The county was under a tornado watch, issued at 15:30 UTC and running to 21:18 UTC.

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 16:28 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.
