What happened

The episode as NWS PHI wrote it up.

Heavy rain fell across Monmouth County and the southern half of New Jersey from the morning into the evening of the 7th. Storm totals averaged between 1.5 and 3.0 inches and caused poor drainage flooding. The Cooper River in Haddonfield (Camden County) briefly touched its 2.8 foot flood stage at 10 p.m. EDT on the 7th. In Atlantic County, road closures and basement flooding were reported in Egg Harbor Township, Hamilton Township, Northfield City and Pleasantville City. In Ocean County, the heavy rain caused a road collapse in Mantoloking Borough. In Monmouth County, southbound New Jersey State Route 35 was closed in Aberdeen Township and New Jersey State Routes 33 and 34 were closed in Wall Township westward to the Howell Township border. Storm totals included 3.10 inches in Estell Manor (Atlantic County), 2.92 inches at the Atlantic City International Airport, 2.76 inches in Absecon (Atlantic County), 2.47 inches in Margate (Atlantic County), 1.96 inches in Millville (Cumberland County), 1.67 inches in Wrightstown (Burlington County) and 1.19 inches in Pennsauken (Camden County).

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
450 AM EDT SAT JUN 7 2003

DUAL SFC LOW PRES...WITH SYSTEM TARGETING US RUNNING NE FROM THE TN
RVR VALLEY AND UP THE MTNS TODAY...THEN OFF THE DELMARVA ACCORDING
TO THE GFS AND OFF THE SRN NEW ENGLAND COAST ACCORDING TO THE ETA
OVERNIGHT. QUICK LOOK AT VARIOUS FOREIGN MODELS ACTUALLY SUPPORT ETA
OVER GFS...AND GIVEN THE VERY SLOW SE MOVEMENT OF THE UPPER JET THIS
SEEMS PLAUSIBLE. THIS ALLOWS PWATER VALUES NEAR OR ABOVE 2.0
INCHES...H8 DWPTS WELL IN EXCESS OF 10 DEG C...UPPER SUPPORT WITH
THE FAVORABLE JET POSITION AND SOME MID LVL DIFLUENCE FOR THE FA
TODAY...AND SO THE FLOOD WATCH IS CONTINUED. ETA DOES NOT BRING ALOT
OF CAPE...SURFACE BASED OR ALOFT...INTO FA AND SOUNDINGS LOOK MORE
LIKE RAIN THAN CONVECTION. THERE IS A STRONG H8 JET INTO AT LEAST
THE SRN FA...BUT THINKING IS THAT THE SFC FLOW RETAINS ENOUGH OF A
MARINE COMPONENT DESPITE PATH OF THE SFC SYSTEM. THEREFORE KEPT OUT
MENTION OF THUNDER. THIS NOT HIGH CONFIDENCE AND MAY BE REVISITED.

TONIGHT THE SYSTEM MOVES OFF AND SOME DRYING INDICATED BY VARIOUS
MODELS. SFC FLOW DOESNT LOOK STRONG AS UPPER JET JUST HANGS AROUND
AREA AND DOES NOT ALLOW FOR A DECENT CHANGE OF AIRMASS. WITH
ANTICIPATED RAINFALL TODAY...PUT IN AREAS OF FOG. SUNDAY APPEARS TO
BE DRY...ALTHOUGH NOT HIGH CONFIDENCE HERE EITHER AS AM BOTHERED BY
THE PSBLTY THAT SOME FORCING MIGHT BE INDUCED BY PESKY UPPER JET.
BY SUN NIGHT INTO MON MORNING THE PROGGED INSTAB PER ETA...LINGERING
MOISTURE...PSBL FORCING ALOFT AND PROGGED SFC BOUNDARY INTO FA MADE
ME TARGET A CHANCE OF CONVECTION FOR THAT PERIOD. TOOK OUT THE
CHANCES OF LINGERING SHOWERS FOR LATE MON...THEN NO CHANGES TO PREV
FCST.

FOR TEMPS TODAY...OVER NRN AND CENTRAL ZONES STAYED ON LOW SIDE OF
GUIDANCE AS EXPECT A RAIN COOLED AND MARINE FLOW TYPE OF DAY...BUT
IN THE SRN ZONES...GIVEN AM BUYING THE MORE NRLY TRACK OF THE SFC
SYSTEM...WARMED TEMPS A BIT ABOVE PREV FCST. THEN MOVED CLOSER TO
THE WARM SIDE OF GUIDANCE UNTIL BOUNDARY AND THE SUPPORTING UPPER
JET FINALLY CLEAR THE FA LATER MON.

MARINE FORECASTER CONCERNED ABOUT SEAS...AND ALSO EYEING THE JET
ABOVE THE SFC...AND HEADLINE THAT SCA MAY NEEDED LWR BAY AND
COAST TONIGHT.
