A protracted precipitation event that started as a wintry mix and then changed to rain caused flooding across Eastern Pennsylvania. Precipitation changed to plain rain mainly before sunrise on the 13th and fell continuously through the late afternoon on the 13th. The heaviest rain fell during the first half of the day on the 13th. The combination of the heavy rain and snow and ice melt caused flooding of many creeks and smaller rivers as well as poor drainage flooding in urban areas. Clogged catch basins exacerbated the problems. Storm totals averaged between two and three and a half inches.
The prolonged precipitation event was caused by the slow moving frontal system that went from Ohio on the early evening of the 12th and took until the afternoon of the 13th to move off of the New Jersey and Delaware coasts. A series of low pressure systems moved north along the frontal boundary and brought steady and in some cases heavy rain into the region.
