A warm front lifted northeast across Pennsylvania, just ahead of a line of convection. Dewpoints in the mid 60s to near 70 spread eastward with time and increased in coverage. Strong heating and destabilization occurred in strong deep layer west/southwestly flow. Low-level lapse rates steepened, and 30-40 knot southwest winds around 700mb increased support for damaging thunderstorm wind gusts. Vertical shear supported rotating updrafts and a few supercell structures.

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, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 19:48 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 Pittsburgh radar (KPBZ), 73 km away, was scanning. The volume nearest the touchdown began at 22:41 UTC.

21 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.
