During the evening and overnight high tide cycle on April 30th, low end minor tidal flooding occurred in Sussex County, but the tidal flooding became progressively worse farther up Delaware Bay and into the tidal Delaware River. Along the tidal Delaware River in New Castle County, moderate tidal flooding occurred as freshwater runoff exacerbated the flooding.

What happened
The episode as NWS PHI wrote it up.
During the evening and overnight high tide cycle on April 30th, low end minor tidal flooding occurred in Sussex County, but the tidal flooding became progressively worse farther up Delaware Bay and into the tidal Delaware River. Along the tidal Delaware River in New Castle County, moderate tidal flooding occurred as freshwater runoff exacerbated the flooding. The highest tide for the event at Breakwater Harbor (Lewes, Sussex County) was 6.91 feet above mean lower low water on the evening of April 29th. Minor tidal flooding starts at 6.0 feet above mean lower low water. The highest tide at Reedy Island (New Castle County) reached 8.25 feet above mean lower low water at 1254 a.m. EDT on May 1st. Moderate tidal flooding starts at 8.2 feet above mean lower low water.
The tidal flooding was caused by the combination of a strong high pressure system that built over the Canadian Maritimes that initiated the onshore flow and a strong, but slow moving low pressure system. The low pressure system was located in northwest Missouri on the morning of April 29th. It moved northeast to near Chicago during the afternoon of April 29th. The low pressure system then became nearly stationary in southern Wisconsin as its cold front reached Ohio early on April 30th. Then a new low pressure system developed on the frontal boundary and was over Eastern Tennessee on the morning of April 30th. The low pressure system reached West Virginia during the late afternoon on April 30th as its warm front started to move through Delmarva. The low pressure system reached north central Maryland at 11 p.m. EDT on April 30th as its warm front reached extreme southeast Pennsylvania and central New Jersey. The low pressure system reached the Allentown, Pennsylvania area at 5 a.m. EDT on May 1st and then was absorbed again into the frontal boundary associated with the original low as it moved into New York State that morning. The steady rain ended as the low pressure system passed north of the Eastern Shore. But the formation of the second low pressure system and the passage of the warm front helped veer the winds from the east to the southeast and enhanced the surface flow up the Delaware Bay that produced the most tidal flooding.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
1236 AM EDT THU MAY 1 2014
.SYNOPSIS...
A WARM FRONT WILL LIFT THROUGH MUCH OF THE AREA OVERNIGHT,
FOLLOWED BY A COLD FRONT THURSDAY MORNING AS LOW PRESSURE
CONTINUES TO DRIFT INTO THE GREAT LAKES REGION THEN INTO EASTERN
CANADA. HIGH PRESSURE WILL BUILD TO OUR SOUTH THROUGH THE WEEKEND
WHILE LOW PRESSURE SLIDES TO OUR NORTH SATURDAY NIGHT INTO SUNDAY,
DRAGGING A COLD FRONT ACROSS THE AREA SUNDAY. HIGH PRESSURE IS
EXPECTED TO BUILD SOUTHWARD ACROSS THE AREA MONDAY INTO TUESDAY
FROM CENTRAL CANADA.
&&
.NEAR TERM /UNTIL 6 AM THIS MORNING/...
NUMEROUS FLOOD WARNINGS REMAINED IN EFFECT FOR OUR AREA AT 1230
AM WITH MUCH OF OUR REGION RECEIVING FROM TWO TO SIX INCHES OF
RAINFALL.
THE WARM FRONT HAD LIFTED INTO SOUTHEASTERN PENNSYLVANIA AND
CENTRAL NEW JERSEY. IT WILL CONTINUE TO DRIFT NORTHWARD DURING THE
BALANCE OF THE NIGHT. TEMPERATURES WERE MAINLY IN THE UPPER 50S
AND 60S TO THE SOUTH OF THE BOUNDARY AND IN THE UPPER 40S AND
LOWER 50S TO THE NORTH.
SOME MODERATE TO HEAVY RAIN REMAINED OVER OUR NORTHERN COUNTIES
AT 1230 AM. IT SHOULD CONTINUE TO LIFT NORTHWARD AND OUT OF OUR
FORECAST AREA BY 130 AM. SCATTERED SHOWERS WILL LINGER FOR THE
BALANCE OF THE NIGHT. WE HAVE LOWERED THE PRECIPITATION
PROBABILITIES AND THE RAINFALL AMOUNTS FOR THE REST OF THE
OVERNIGHT PERIOD BASED ON RADAR TRENDS.
&&
.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM TODAY/...
SLOW IMPROVEMENT IS EXPECTED ON THU AS THE LOW FINALLY MOVES AWAY
FROM THE REGION. TEMPS SHOULD RESPOND IN KIND, ESPECIALLY IF WE
GET SOME AFTN SUNSHINE. THERE COULD BE SOME LINGERING PRECIP
EARLY, IF THE SLOWER SOLNS ARE CORRECT BUT A BETTER DAY IS IN
STORE, OVERALL.
&&
.LONG TERM /TONIGHT THROUGH WEDNESDAY/...
THE COLD FRONT WILL MOVE WELL OFFSHORE THURSDAY NIGHT, WHILE LOW
PRESSURE MOVES THROUGH THE GREAT LAKES INTO EASTERN CANADA. THERE
COULD BE SOME LINGERING SHOWERS ACROSS THE COASTAL WATERS AND THE
FAR SOUTHEASTERN PART OF THE AREA, SO SLIGHT CHANCE POPS REMAIN
THERE.
THE LOW ACROSS EASTERN CANADA IS EXPECTED TO SPLIT ON FRIDAY,
WITH ONE PIECE MOVING INTO THE CANADIAN MARITIMES, WHILE THE OTHER
RETROGRADES INTO CENTRAL CANADA. AS THIS HAPPENS, BOTH A WEAK
SURFACE TROUGH AND MID-LEVEL SHORT WAVE/VORT MAX ARE FORECAST TO
TRACK ACROSS THE AREA ON FRIDAY. THERE IS NOT A SIGNIFICANT AMOUNT
OF MOISTURE ASSOCIATED WITH THESE FEATURES, BUT THERE MAY BE
ENOUGH TO CREATE A FEW SCATTERED SHOWERS ACROSS OUR NORTHERN ZONES
DURING THE AFTERNOON FRIDAY. ANY SHOWER ACTIVITY SHOULD DISSIPATE
BY SUNSET WITH THE LOSS OF DAYTIME HEATING.
A SIMILAR SITUATION IS FORECAST TO OCCUR ON SATURDAY AS FRIDAY
WITH A SHORT WAVE/VORT MAX MOVING THROUGH, WITH A WEAK SURFACE
REFLECTION AS WELL. THERE LOOKS TO BE A LITTLE MORE MOISTURE TO
WORK WITH ON SATURDAY, SO POP CHANCES ARE SLIGHTLY HIGHER
SATURDAY, WITH POPS GENERALLY FOR THE NORTHERN HALF OF THE AREA,
WITH HIGHEST ACROSS THE NORTHWEST. ANY SHOWER ACTIVITY WILL
DISSIPATE WITH DAYTIME HEATING AFTER THE SUNSETS, BUT IF THEY ARE
MORE WIDESPREAD THAN FRIDAY, THEY COULD LAST FOR A COUPLE OF HOURS
AFTER SUNSET.
ON SUNDAY, THE LOW ACROSS CANADA WILL MOVE INTO NEW ENGLAND AND
FINALLY BRING A COLD FRONT ACROSS THE AREA. ALTHOUGH THERE STILL
IS NOT MUCH MOISTURE TO WORK WITH, THERE WILL BE PRECIPITATION
CHANCES FOR ALL AREAS, WITH THE HIGHEST ACROSS THE NORTHERN TWO-
THIRDS OF THE AREA. THE FRONT IS EXPECTED TO MOVE OFFSHORE LATE IN
THE DAY OR DURING THE EVENING, SO PRECIPITATION CHANCES SHOULD END
BY SUNDAY NIGHT.
FOR MONDAY INTO TUESDAY, HIGH PRESSURE IS EXPECTED TO BUILD
ACROSS THE AREA FROM CENTRAL CANADA. THIS WILL PROVIDE DRY WEATHER
FOR EARLY NEXT WEEK. THE GFS AND ECMWF DO SHOW SOME QPF ON THE
EASTERN SIDE OF THE UPPER RIDGE THAT BUILDS ACROSS THE CENTRAL
PART OF THE COUNTRY, BUT THEY HAVE LOCATION DIFFERENCES. THE GFS
BRINGS THE PRECIPITATION RIGHT OVER OUR AREA TUESDAY INTO TUESDAY
NIGHT, WHILE THE ECMWF KEEPS THIS PRECIPITATION TO OUR SOUTH,
GENERALLY AROUND THE SAME TIME PERIOD. FOR NOW, WE WILL KEEP THE
FORECAST DRY UNTIL OUR CONFIDENCE BUILDS.
ON WEDNESDAY, THE SURFACE HIGH BUILDS OFFSHORE, WHILE THE UPPER
RIDGE BUILDS CLOSER TO THE AREA, AND A WARM FRONT APPROACHES THE
AREA. THEREFORE, PRECIPITATION CHANCE DO INCREASE BY WEDNESDAY
INTO WEDNESDAY NIGHT.
&&
.AVIATION /06Z THURSDAY THROUGH MONDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY AND SURROUNDING AREAS.
WIDESPREAD IFR ACROSS THE TERMINALS THIS EVENING. THESE
CONDITIONS WILL CONTINUE OVERNIGHT WITH SHOWERS EARLY AND SOME
DRIZZLE LATE. THERE WILL BE SOME IMPROVEMENT DURG THE MRNG HOURS
ON THU. HOWEVER, HAVE SLOWED THE IMPROVING TREND ON THU. AN E TO
NE WIND WILL GRADUALLY BECOME S THIS EVE AS A WMFNT MOVES THRU.
EXPECT SPEEDS IN THE 10 TO 15 KT RANGE WITH GUSTS TO 25 KTS. THERE
WILL BE SOME LLWS AS WELL.
OUTLOOK...
THURSDAY NIGHT-FRIDAY NIGHT...MOSTLY VFR. GUSTY WEST WINDS AROUND
20 KNOTS FRIDAY AFTERNOON. ISOLATED SHOWERS ACROSS FAR NORTHWEST
SATURDAY-SATURDAY NIGHT...MOSTLY VFR. AFTERNOON SHOWERS POSSIBLE,
MAINLY NORTHWESTERN TAFS. GUSTY SOUTHWEST WINDS 15-20 KNOTS.

PASSAGE WITH BRIEF MVFR CONDITIONS POSSIBLE. GUSTY SOUTHWEST WINDS
EARLY, THEN NORTHWEST LATER BEHIND FRONT AROUND 20-25 KNOTS.
SUNDAY NIGHT-MONDAY...MOSTLY VFR. GUSTY NORTHWEST WINDS 20-25
KNOTS.

WILL DROP THE GLW ON THE NRN WATERS WITH THIS PKG. WILL GO WITH A
SCA EVERYWHERE. THE BAY HAS BEEN HARD PRESSED TO HIT SCA TODAY,
