• Aerial imagery from Google Earth shows hundreds of trees were snapped and uprooted in this area
• Aerial imagery from Google Earth shows thousands of trees were snapped and uprooted in a nearly 1 mile wide path in this area
• Aerial imagery from Google Earth shows hundreds of trees were snapped and uprooted around and north of the Myatt Creek Road and Turner Creason Road intersection
• Aerial imagery from Google Earth shows dozens of trees were snapped and uprooted in this area

A strong storm system moving across the Ohio and Tennessee Valleys caused scattered strong to severe thunderstorms to develop across eastern portions of Middle Tennessee during the afternoon hours. Two supercell thunderstorms spawned four tornadoes resulting in a total of 3 fatalities and 7 injuries. Numerous other reports of wind damage and large hail were received.

An EF2 tornado with maximum wind speeds around 125 mph touched down along Castro-Pugh Road just north of Plateau Road in northern Cumberland County. Intermittent damage continued to the east-northeast for approximately 1 mile before the damage became continuous along Clear Creek Road. Hundreds of trees were uprooted and snapped and a home suffered roof damage in this area.||The tornado continued east-northeast and reached EF2 intensity in the Rinnie community along Highway 127. A brick home slid off its foundation and was completely destroyed, killing one woman, and another nearby home lost its entire roof. A double wide mobile home along Hollow Road was also completely destroyed, killing another woman, with debris tossed hundreds of yards. At least a thousand trees were uprooted or snapped around this location. New aerial imagery from Google Earth released in Spring 2013 indicated the tornado continued eastward and widened to 1/2 mile, blowing down thousands of more trees as it moved across inaccessible forested areas of northern Cumberland County. Damage was apparent eastward to past Roy Taylor Road.

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 Moderate Risk, with a 0.15 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 20:24 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.
