High pressure across the western Atlantic led to southerly flow across the region. This led to hot and humid conditions ahead of an advancing cold front. Showers and thunderstorms moved across the region and some thunderstorms produced damaging winds.

The tornado was estimated to have touched down at approximately 737 PM EDT in the 500 Block of Tub Run Hollow Road. Extensive tree damage occurred in this area. Several dozen trees were snapped and topped and another was uprooted near a house. The tree debris pattern was convergent in nature indicating tornadic rotation. The tornado traveled approximately 130 yards towards the north northeast along Tub Run Hollow Road where it snapped and topped additional trees on both sides of the road before lifting at approximately 738 PM EDT.

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. The outlook in force was issued at 20:01 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.
