The episode as NWS CTP wrote it up.
Heavy rainfall between 1 and 2 inches over northwest Pennsylvania and 2 to 4 inches across central and eastern Pennsylvania combined with snowmelt in the northern mountains to produce significant flooding. The worst flooding occurred over the eastern half of the Commonwealth. A dozen river forecast points crested over moderate flood stage, with many others rising over cautionary and minor flood levels. Numerous road closures resulted from flooding of low-lying areas and small streams and creeks overflowing their banks. Multiple water rescues and isolated evacuations were reported along with one drowning fatality.
