The episode as NWS OKX wrote it up.
Thunderstorms associated with a strong cold front produced torrential downpours and caused flash flooding in Bergen County.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
1104 AM EDT THU APR 28 2011
.SYNOPSIS...
A MOIST SOUTHERLY FLOW WILL PREVAIL TODAY AHEAD OF AN APPROACHING
COLD FRONT. THE FRONT WILL CROSS THE AREA LATE THIS AFTERNOON INTO
TONIGHT...FOLLOWED BY AN UPPER LEVEL DISTURBANCE AND ACCOMPANYING
SURFACE LOW PRESSURE TROUGH ON FRIDAY. HIGH PRESSURE WILL THEN
BUILD INTO THE AREA FOR THE WEEKEND. A WARM FRONT WILL LIFT NORTH
OF THE REGION ON MONDAY...THEN A COLD FRONT WILL SLOWLY APPROACH
FROM THE WEST FROM TUESDAY INTO WEDNESDAY.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
NEW SEVERE TSTM WATCH 253 IN EFFECT UNTIL 20Z FOR ALL OF THE
SOUTHERN HUDSON VALLEY AND NORTHEAST NJ...EAST THROUGH SOUTHWEST
CT AND WESTERN LONG ISLAND.
TWO SMALL LINE SEGMENTS HAVE ALREADY QUICKLY MOVED THROUGH NYC AND
SOUTHERN CT...WEAKENING AS THEY ENCOUNTERED THE STABLE MARINE
LAYER. MUCH OF THE FORECAST AREA CURRENTLY DRY WHILE A LARGE LINE
OF CONVECTION ADVANCES FROM THE WEST. NUMEROUS SEVERE TS WARNINGS
ALREADY ALONG THIS LINE...AS EMBEDDED BOW ECHOES/QLCS-LIKE
FEATURES RACE OFF TO THE NORTHEAST. THESE STORMS ARE CURRENTLY
ENTERING ORANGE COUNTY...AND SHOULD SPREAD INTO THE NORTHEAST NJ
AND NYC OVER THE NEXT FEW HOURS. MLCAPE IS MODEST AT ABOUT 500
J/KJ OVER NORTHEAST NJ...BUT 0-6KM SHEAR IS INCREASING TO 60-70
KT. DAMAGING WINDS WILL BE THE MAIN THREAT...ENHANCED BY 60KT
LOW-LEVEL JET WINDS POSSIBLY MIXING DOWN TO THE SURFACE IN
CONVECTIVE ELEMENTS. ISOLATED TORNADOES CANNOT BE RULED OUT WITH
0-1KM SRH VALUES RANGING FROM 400-500 M2/S2...AND LCLS AROUND 1KM.
MAIN QUESTION WITH THE FORECAST IS WHETHER THESE STORMS CAN MAINTAIN
THEIR SEVERITY AS THEY REACH THE EASTERN HALF OF THE CWA. STABLE
MARINE LAYER WILL STILL BE IN PLACE...SO STORMS WILL LIKELY BECOME
ELEVATED.
PW INCREASES TO OVER 1.5 INCHES AS THE LOW-LEVEL JET AXIS ORIENTS
ITSELF OVER THE FORECAST AREA. STORMS COULD PRODUCE VERY HEAVY
RAIN AND FLASH FLOODING...SO THE FLASH FLOOD WATCH FOR NYC
METRO...NORTHEAST NJ AND THE LOWER HUDSON VALLEY CONTINUES.
HIGH SURF ADVISORY CONTINUES THROUGH 2 AM AS A RESULT OF A STRONG
SOUTHERLY FLOW AND SOUTHERLY SWELL. SURF HEIGHTS OF 6-9 FT AT THE
OCEAN BEACHES WILL RESULT IN WASHOVERS AND MINOR TO MODERATE BEACH
EROSION.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/...
ACTIVITY WILL DIMINISH THIS EVENING AS THE COLD FRONT MOVES
THROUGH...FOLLOWED BY CLEARING SKIES. UPPER LEVEL TROUGH AND SFC
REFLECTION PASSING THROUGH ON FRI MAY TRIGGER SOME INSTABILITY
SHOWERS ACROSS THE INTERIOR. THIS TROUGH MAY CAUSE WINDS TO BECOME
A BIT GUSTY DURING THE AFTERNOON AS IT MOVES THROUGH...WHICH MAY
ALLOW FOR BETTER MIXING AND LOWERING OF DEWPTS. THIS IN TURN MAY
ALLOW TEMPS TO RISE A BIT HIGHER THAN CURRENTLY FORECAST.
&&
.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
MEDIUM RANGE MODELS IN FAIRLY GOOD AGREEMENT EARLY IN THIS
PERIOD...BUT DEVIATE BEYOND THIS WEEKEND AS THE LONG WAVE UPPER
LEVEL PATTERN FURTHER AMPLIFIES WITH THE DEVELOPMENT OF STRONG UPPER
LEVEL RIDGE IN THE WESTERN AND CENTRAL ATLANTIC WHICH SLOWS THE EXIT
OF LONG WAVE TROUGH ACROSS THE EASTERN STATES..WHILE ANOTHER LONG
WAVE TROUGH DIGS AS IT ENTERS THE WESTERN STATES. SO...TIMING OF
SURFACE FEATURES WILL NOT BE VERY GOOD BEYOND SUNDAY...BUT COULD
ALSO MEAN DRY WEATHER MAY HANG IN INTO EARLY NEXT WEEK.
SATURDAY-SUNDAY...WITH AMPLIFIED LONG WAVE UPPER PATTERN IN
PLACE...SURFACE FEATURES WILL TEND TO SLOW DOWN. SO...EXPECT A
RATHER NICE WEEKEND FOR THE MAJORITY OF THE REGION. HIGH PRES WILL
BUILD OFFSHORE S OF LONG ISLAND DURING THE WEEKEND...WHICH MEANS
RATHER PLEASANT AND DRY WEATHER. EXPECT HIGHS MAINLY IN THE 60S TO
LOWER 70S...BUT COOLER ALONG THE COAST WITH SEA BREEZES KICKING UP.
MODELS START TO DIVERGE LATER SUNDAY AND SUNDAY NIGHT TIMING THE
APPROACH OF NEXT FRONTAL SYSTEM FROM THE LAKES AND MIDWEST. NOTING
THE HIGHLY AMPLIFIED UPPER PATTERN...FEEL THAT THE GFS IS MOVING
THIS NEXT FEATURE TOO FAST. THE GGEM AND ECMWF APPEAR TO BE
HANDLING THIS A BIT BETTER...SO WENT ALONG WITH A BLEND OF THEIR
SOLUTIONS TO KEEP DRY CONDITIONS THROUGH SUNDAY. MAY START TO SEE
CLOUDS APPROACHING SE NY/N NJ SUNDAY NIGHT AS WARM FRONT APPROACHES.
MONDAY...CONFIDENCE FOR THIS PORTION OF THE FORECAST DECREASES
DURING THIS TIME FRAME WITH A VARIETY OF SOLUTIONS FOR THE TIMING
OF THE APPROACHING FRONT. FOR NOW...KEPT MAINLY SLIGHT CHANCE POPS
FOR MOST AREAS...WITH ONLY A LOW CHANCE MOVING INTO WESTERN AREAS.
HOWEVER...IF THE 12Z OP ECMWF MODEL IS RIGHT...MAY STILL BE TOO
FAST WITH THE ONSET OF PRECIP. HAVE PRECIP MOVING INTO MOST AREAS
DURING MONDAY NIGHT.
TUESDAY-WEDNESDAY...CURRENT TIMING SUGGESTS THE FRONT ONLY SLOWLY
CREEPING ACROSS THE REGION WHILE WEAK WAVES OF LOW PRES MOVE ALONG
IT. SO...FOR NOW...EXPECT MAINLY CLOUDY AND COOL CONDITIONS WITH
CHANCE SHOWERS. DID NOT MENTION THUNDER AT THIS POINT...BUT COULD
HEAR A RUMBLE OR TWO WITH WEAK LOWS ON THE FRONT ENHANCING ANY
LIFT.
&&
.AVIATION /15Z THURSDAY THROUGH MONDAY/...
LINE OF CONVECTION OVER EASTERN PA/WESTERN NJ AND EXTENDING DOWN
THE APPALACHIANS AND INTO THE DELMARVA AREA CONTINUES TO TRACK
NORTHEAST. TAFS LOOK GOOD BRINGING CONVECTION INTO THE WESTERN
TERMINALS AFTER 15Z...AND TAFS WILL BE UPDATED TO INCLUDE TSRA AS
THESE STORMS APPROACH.
WIDESPREAD MARINE LAYER WITH SUB-IFR CONDITIONS ACROSS LONG
ISLAND...COASTAL CT...AND RIGHT ALONG THE SOUTH SHORE OF
NYC...IMPACTING KJFK.
SEVERE THUNDERSTORM WATCH ISSUED THROUGH 4 PM EDT FOR TERMINALS
WEST OF A LINE FROM FAIRFIELD COUNTY TO NASSAU COUNTY. PRIMARY
THREAT IS DAMAGING WINDS...AND HEAVY RAIN WILL BE LIKELY AS WELL.
SOUTHERLY WINDS WILL GENERALLY BE AROUND 15 TO 20 KT WITH GUSTS
INTO THE 20S. HIGHER GUSTS...POSSIBLY UP TO 30 KT CAN BE EXPECTED
AT KJFK AND KISP.
THE COLD FRONT CROSSES THE REGION BETWEEN 23Z-04Z WITH IMPROVEMENT
TO VFR.
...NY METRO ENHANCED AVIATION WEATHER SUPPORT...

FRIDAY...MEDIUM TO HIGH CONFIDENCE FOR VFR. W-NW WINDS MAY BECOME
GUSTY DURING THE AFTERNOON.
SATURDAY-SUNDAY...MEDIUM TO HIGH CONFIDENCE FOR VFR. W-NW FLOW
COULD BE GUSTY SATURDAY AFTERNOON.
MONDAY...MEDIUM CONFIDENCE FOR VFR. CLOUDS INCREASE FROM W-E
DURING THE AFTERNOON. LOW CONFIDENCE FOR MVFR CIGS/VSBYS IN SCT
SHOWERS MONDAY NIGHT.
&&
.MARINE...
DENSE FOG ADVISORY FOR ALL WATERS EXCEPT NY HARBOR HAS BEEN EXTENDED
INTO THIS AFTERNOON. SOUTHERLY FLOW WITH DEWPOINTS HIGHER THAN SEA
SURFACE TEMPS WILL SERVE TO AT LEAST HOLD IN LOW CLOUDS...BUT ALSO
PROBABLY KEEPS VSBY AT 1NM OR LESS FOR A LARGE ENOUGH AREA TO
WARRANT THE ADVISORY.
SCA CONTINUES ON ALL WATERS FOR TODAY AND HAVE EXTENDED IT ON THE
OCEAN WATERS THROUGH FRI. STRONG SOUTHERLY FLOW AHEAD OF A COLD
FRONT WILL CAUSE 15 TO 25 KT SUSTAINED ON THE WATERS...HIGHEST OVER
THE OCEAN. MAY BE ABLE TO MIX SOME OF THE STRONG LOW LEVEL JET DOWN
WITH GUSTS OCCASIONALLY REACHING 35KT...BUT THIS WOULD BE CONFINED
TO AREAS NEAR SHORE.
COLD FRONT PUSHES THROUGH THIS LATE THIS AFTERNOON AND EVENING AND
WINDS WILL DIMINISH. WINDS MAY LINGER A FEW HOURS LONGER THAN
CURRENTLY EXPECTED AND SCA MAY NEED TO BE EXTENDED AS A RESULT.
SOUTHERLY SWELL BEING INDICATED BY WAVEWATCH GUIDANCE IS WHAT WILL
KEEP ROUGH SEAS ON THE OCEAN WATERS THROUGH FRI...POSSIBLY INTO
SATURDAY.
A TROUGH OF LOW PRESSURE WILL MOVE ACROSS THE AREA FRI...THEN HIGH
PRESSURE BUILDS IN FOR THE WEEKEND WITH TRANQUIL CONDITIONS
RETURNING INTO EARLY NEXT WEEK.
&&
.HYDROLOGY...
RAINFALL TOTALS OF 0.50 TO 1.25 INCHES EXPECTED IN SHOWERS AND
TSTMS FROM LATE TONIGHT INTO THU...WITH LOCALLY AS MUCH AS 2-3

FLOODING. LARGER RIVERS SHOULD BE ABLE TO HANDLE THIS AMOUNT OF
RAINFALL...WITH ONLY MINOR RISES EXPECTED.
