What happened

The episode as NWS PHI wrote it up.

A coastal low pressure system cause heavy rain to fall throughout the evening of the 14th in Kent and Sussex Counties. During heavier bursts of precipitation, especially during the early part of the evening, the rain mixed with snow across northern sections of Kent County. The heavy rain caused the usual poor drainage flooding, but no other serious problems were reported. Storm totals included 2.17 inches in Salisbury, MD, 1.90 inches in Milford and 1.52 inches in Dover. The low pressure system developed along the Gulf Coast States the morning of the 13th. During the morning of the 14th it had moved into Alabama and was located just east of the Delmarva Peninsula around daybreak of the 15th. The storm intensified and moved rapidly offshore on the 15th and reached Nova Scotia the morning of the 16th.
