An F1 tornado touched down about 6:30 p.m. EST in Southampton Township in Franklin County on the west side of Shippensburg. The storm moved east and northeast about 3 miles causing the most destruction across southeast sections of Shippensburg in Cumberland County. Along a path width of 1/4 mile, many trees were blown down or damaged and a number of homes had minor structural damage. One home had a roof blown off in the southeast section of town on Old Baltimore Road.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

24 minutes of warning. NWS CTP issued a tornado warning for this county at 23:06 UTC, 24 minutes before the tornado touched down, in force until 00:15 UTC.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. 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 05:57 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

The radiosonde launches on either side of the tornado, from the nearest station that was launching then, drawn and analyzed the way Storm Lab does: the same diagram, the same parcel and shear definitions SPC's mesoanalysis uses.

The State College radar (KCCX), 106 km away, was scanning. The volume nearest the touchdown began at 23:28 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.
