Another in a series of strong upper level troughs pushed through the southeast states, resulting in another enhanced risk of severe storms from the Storm Prediction Center. The tri-state area was hit fairly hard again, with numerous reports of wind damage documented along with several tornadoes.

Initial damage was noted near the intersection of Owen Place and Piney Grove Roads. From the touchdown point, damage, consisting of hundreds of snapped and uprooted trees, was continuous right to the Jackson County border along Corbin Rd. The tornado|intensified as it moved across Jackson County. In addition to downing many hundreds of trees there was significant structural damage at two locations. The first was at a farm off Farren Ranch Road where a two story outbuilding/home was completely|destroyed with debris thrown several hundred yards. The second was along Bethlehem Rd. south of Kynesville Rd. where several mobile homes suffered significant damage. One of the mobile homes was completely destroyed with it's frame wrapped into a tree. |Fortunately the mobile home was vacant at the time.

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.
