The first Pike County tornado touched down 1.2 miles south of Barry, at the intersection of 1850N and 1750E. The tornado damaged a house at this location that was made of prefabricated panels of compressed Styrofoam insulation. The roof was completely lifted off with some of the panels being deposited 250 yards to the north. The entire north wall fell away from the structure. Debris was scattered across an open field up to one mile to the northeast. At this location, the tornado was 100 yards wide and produced F0 damage. Further to the northeast along the track on 1900N, several outbuildings were damaged and a two foot diameter walnut tree was blown over. The residence had minor shingle, siding and trim damage. The tornado was 200 yards wide and produced F0 damage at this location. The tornado continued northeast 3.5 miles toward Hadley, crossing I-72 near mile marker 22. Along this portion of the track, the tornado caused minor exterior damage to residences and produced minor tree damage. The tornado ranged from 50 to 100 yards wide and produced F0 damage. In Hadley, a two story brick home sustained extensive damage. The roof was lifted off and destroyed. The back half of the second story was completely demolished. Extensive tree damage also occurred. A grain wagon and auger were tipped over. A barn lost some of its tin roof and two wooden telephone poles were leaning east. Debris was scattered northeast for about half a mile. At this location, the tornado was 150 yards wide and produced F1 damage. The tornado dissipated one mile northeast of Hadley.

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 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 00:42 UTC.

25 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.
