What happened

The episode as NWS PHI wrote it up.

A low pressure system developed over the lower Tennessee Valley the morning of the 24th and moved northeast passing through the eastern Great Lakes by the morning of the 25th. It tapped moisture over the Gulf of Mexico and Western Atlantic and produced heavy rain across Central New Jersey. The heaviest rain fell from the evening of the 24th through the pre-dawn hours on the 25th. Storm totals averaged one inch to one and a half inches with the heaviest rain falling in Hunterdon County. The ground was still saturated from the heavy rains of the previous month and this led to river flooding in Somerset County as well as the usual urban and poor drainage flooding in low-lying areas in other counties. The Raritan River at Manville exceeded its 12 foot flood stage from 1115 a.m. EST through 5 p.m. EST on the 25th. It crested at 12.7 feet at 2 p.m. EST. Storm totals included 1.63 inches in Flemington (Hunterdon County), 1.58 inches in Lebanon Township (Hunterdon County), 1.39 inches in New Brunswick (Middlesex County), 1.32 inches in South Plainfield (Middlesex County), 1.28 inches in Hightstown (Mercer County), 1.2 inches in Blackwells Mills (Somerset County), 1.19 inches at McGuire AFB and 1.13 inches in Cherry Hill (Camden County).
