A very moist southerly flow originating from the Gulf of Mexico combined with a slow-moving low pressure system over the Upper Midwest and Great Lakes produced heavy rainfall (3-5+ inches) across southeastern Pennsylvania over a two-day period. The heavy rain lead to considerable flooding of roadways and small streams across portions of the Lower Susquehanna Valley. Minor flood stages were exceeded on the Conestoga River at Lancaster and Swatara Creek at Hershey early on May 1, 2014.
