An intensifying storm system moved across upstate New York and into southern Quebec early in the morning on the 31st. This system dragged a warm front across northeastern Pennsylvania. Behind this front, a southerly flow of warm, moist, and unstable air quickly developed. This set the stage for the development of severe weather later that afternoon as a cold front and strong upper air disturbance approached. From late in the afternoon until late that evening, northeastern Pennsylvania was under siege from severe thunderstorms, including several tornadic supercells. In all, nine separate tornadoes touched down on this day. Overall damage estimates run into the millions with many homes and structures heavily damaged or destroyed. The most devastating storms occurred in Pike county. Within about a 3 hour stretch from 7 to 10 pm EDT, four different twisters affected the county. One tornadic cell was responsible for knocking down thousands of healthy large trees in and around Promised Land State Park with several vacation homes damaged or leveled. Fortunately, injuries were kept at a minimum. Widespread straight line wind damage also occurred with hailstones the size of ping pong balls falling in some places. The north side of Scranton had extensive wind damage as a storm passed through shortly before 10 pm EDT and sections of Wayne and Luzerne counties had roads closed and/or blocked from falling trees for more than 2 days after the storm. Pennsylvania Power and Light Company estimated that hundreds of thousands of customers were without power at the height of the storms on the evening of the 31st. Some of the more remote locations did not have power restored for the better part of a week.

A severe thunderstorm intensified and briefly became tornadic over Jackson township in eastern portions of the county around 7:00 pm EDT. Eyewitness reports and damage surveys indicate tree tops were twisted off and a few utility poles were sheared off. The pattern of the damage was chaotic with tree limbs in many directions. The tornado appeared to be near ground level for only a brief time before it lifted back into the cloud base. Fortunately, it touched down away from more populated areas.

45 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.
