The tornado touched down on Maple ValleyRoad in northern Dickson County as an F2. 3 mobile homes were leveled and demolished at this location. Numerous trees were uprooted and snapped. The tornado continued along Highway 49 and reached Bellsburg, TN as an F3. A one story brick home was demolished. No walls or roof were left standing, leaving only a basement and a garage. A truck was thrown into the basement by the tornado. The drywall, furniture, and appliances were hurled into the woods at least 100 yards. An aerial survey determined spotty rural damage to trees as this tornado continued into Cheatham County where it hit Greenbrier and then Ashland City. Dickson County had a total of 25 homes destroyed, 8 homes with major damage, and 24 homes and businesses with moderate damage.

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 High Risk, with a 0.30 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 16:32 UTC.

46 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.
