A few weak areas of low pressure moved along a nearly stationary frontal boundary just south of Long Island. This in combination with an upper level trough also tracking through the area resulted in scattered thunderstorms which produced heavy rainfall and flash flooding in Passaic and Bergen counties.

The episode as NWS OKX wrote it up.
A few weak areas of low pressure moved along a nearly stationary frontal boundary just south of Long Island. This in combination with an upper level trough also tracking through the area resulted in scattered thunderstorms which produced heavy rainfall and flash flooding in Passaic and Bergen counties.
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.
NWS New York, NY wrote its last area forecast discussion before the first event at Jul 28, 1:04 PM EST, 1 hour 51 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NEW YORK NY 204 PM EDT SAT JUL 28 2012 .SYNOPSIS... LOW PRESSURE PERSISTS THROUGH THE WEEKEND AS A FRONT REMAINS NEARLY STATIONARY OVER THE REGION. HIGH PRESSURE BRIEFLY BUILDS IN FOR THE BEGINNING OF THE WEEK...FOLLOWED BY MULTIPLE WEAK FRONTS MID WEEK THROUGH THE END OF THE WEEK. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... WATER VAPOR LOOP SHOWING SHORTWAVE CONTINUES TO APPROACH FROM THE GREAT LAKES WITH EMBEDDED VIGOROUS VORT. SURFACE BASED INSTABILITY INCREASING ACROSS WESTERN PORTIONS OF THE AREA AND INTO WESTERN NEW JERSEY TO 1500 TO 2000 J/KG. AND THUNDERSTORMS ARE BEGINNING TO INCREASE IN COVERAGE AND INTENSITY. WILL CONTINUE WITH THE LIKELY POPS AND HEAVY RAINFALL. SOME STORMS MAY EVEN PRODUCE SMALL HAIL. TEMPERATURES REMAIN TO BE TRICKY WITH THE CONVECTION MOVING THROUGH AND THE CHANCE THAT THERE WILL BE SOME BREAKS OR THIN SPOTS IN THE CLOUD COVER TO ALLOW TEMPERATURES TO QUICKLY RISE...ADDING TO THE SURFACE BASED INSTABILITY. FOR NOW HAVE LOWERED HIGHS A COUPLE OF DEGREES ACROSS NORTHEASTERN NEW JERSEY AND INTO THE LOWER HUDSON VALLEY. THERE IS A MODERATE RISK FOR RIP CURRENTS TODAY. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/... CONTINUED CHC POPS INTO THE FIRST PART OF THE NIGHT AS THE FRONT REMAINS IN PLACE OVER THE REGION AND ANOTHER SFC LOW MOVES ALONG THE FRONT TO THE NORTHEAST. THE MAIN UPPER LEVEL FORCING ASSOCIATED WITH A MUCH MORE PRONOUNCED SHORTWAVE MOVES THROUGH THE NORTHEAST DURING THE NIGHT...WHICH SHOULD KEEP PRODUCING ENOUGH FORCING TO GENERATE SHOWERS AND THUNDERSTORMS. INSTABILITY GREATLY DIMINISHES TONIGHT...BUT 0-6KM BULK SHEAR REMAINS BETWEEN 30 AND 40 KTS. SO MAY SEE ISO TSTORMS...BUT BETTER CHC OF MORE SCT SHOWERS. AS THE LOW MOVES AWAY FROM THE AREA...SHOULD SEE A DECREASED THREAT FOR PRECIP SUN MORNING...WITH CHC POPS AGAIN SUN AFTN. ONCE AGAIN WENT WITH A MET/MAV BLEND FOR TEMPS AS THE MAV IS CONSISTENTLY WARMER. && .LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/... LITTLE CHANGES IN THE LONG TERM TO THE PREVIOUS FORECAST. OVERALL...LOOKING AT A POSSIBLY MESSY WEEK WITH PERSISTENT LOW PRESSURE KEEPING THE CHC FOR PRECIP IN FOR MUCH OF THE WEEK. HIGH PRESSURE BRIEFLY BUILDS IN SUN NIGHT INTO MONDAY...FINALLY ALLOWING FOR A BRIEF DRY PERIOD. HOWEVER...AS A WEAK COLD FRONT BEGINS MOVING IN FROM THE WEST TUESDAY...THERE WILL BE A CHC FOR SHOWERS AND THUNDERSTORMS. THE 00Z GFS WANTS TO DEVELOP AND MOVE THROUGH A DECENT LOW ON TUES...BUT WITH THE REST OF THE MODELS NOT HINTING AT THIS STRONG OF A LOW...WITHHELD FROM INCORPORATING THIS LOW INTO THE FORECAST. OTHERWISE...THE MODELS IN THE LONG TERM ARE IN DECENT AGREEMENT WITH THE PASSAGE OF A WEEK FRONT ON WED...WITH ANOTHER FRONT THURS NIGHT INTO FRI. ALOFT...MULTIPLE SHORTWAVES ARE EXPECTED TO PASS THROUGH THE NORTHEAST. WINDS BECOME MORE SOUTHERLY AHEAD OF THE FRONT...WHICH WILL ASSIST IN INJECTING IN VERY WARM AND MOIST AIR...SO SHOULD SEE A GRADUAL INCREASE IN TEMPS. BASICALLY USED A HPC/MOS BLEND WITH THE PREVIOUS FORECAST TO GENERATE BOTH HIGH AND LOW TEMPS...AS WELL AS DEW PTS. THIS FLOW WILL ALSO KEEP A VERY MOIST AND UNSTABLE AIRMASS IN PLACE...SO WILL KEEP THE THUNDERSTORM WORDING. HOWEVER...LATEST GUIDANCE DOES NOT HINT AT ANY SEVERE WEATHER POTENTIAL FOR THE CWA FOR THE WEEK...WITH HEAVY RAIN BEING THE BIGGEST THREAT. && .AVIATION /18Z SATURDAY THROUGH THURSDAY/... HIGH CONFIDENCE IN SHOWERS AND THUNDERSTORMS BECOMING MORE WIDESPREAD OVER THE AREA THIS AFTERNOON AND CONTINUING THROUGH THIS EVENING. HEAVY RAIN WITH SIGNIFICANTLY REDUCED CIGS/VSBYS ARE EXPECTED. ISOLATED WIND GUSTS ARE ALSO POSSIBLE BUT DID NOT INCLUDE THEM IN THE TAFS DUE TO LOW CONFIDENCE OF THEM OCCURRING AT ANY GIVEN LOCATION. AFTER 02Z...SHOWERS AND THUNDERSTORMS WILL BEGIN TO DIMINISH. CIGS AND VSBYS WILL ONLY MARGINALLY IMPROVE DUE TO EASTERLY FLOW. BY SUNDAY MORNING...EXPECT CONDITIONS TO IMPROVE TO VFR BUT AFTER 14Z. OUTLOOK FOR 18Z SUNDAY THROUGH WEDNESDAY... .SUNDAY THROUGH WEDNESDAY...MAINLY VFR...THOUGH OCCASIONAL SUB-VFR POSSIBLE IN AFTERNOON SHOWERS/THUNDERSTORMS. && .MARINE... WINDS AND SEAS ON TRACK AND NO UPDATES AT THIS TIME. SUB-SCA CONDITIONS EXPECTED THROUGH MID WEEK. WITH A FRONTAL BOUNDARY REMAINING IN PLACE TODAY INTO TOMORROW...SCT SHOWERS AND THUNDERSTORMS ARE POSSIBLE WHICH MAY PRODUCE SOME GUSTY WINDS AND HEAVY RAINFALL. SEAS SHOULD REMAIN BELOW 3 FT ON THE OCEAN...AND LESS THAN 1 FT ELSEWHERE. INCREASING SOUTHERLY WINDS AHEAD OF THE COLD FRONT NEXT WEEK COULD PRODUCE A FEW GUSTS UP TO 25 KTS...AND SEAS ON THE OCEAN UP TO 5 FT. SHOWERS AND THUNDERSTORMS ARE ALSO POSSIBLE THROUGH THE WEEK AS LOW PRESSURE LINGERS IN THE REGION. && .HYDROLOGY... HEAVY RAINFALL ACROSS LONG ISLAND THIS MORNING WAS PRODUCING 1 TO TWO INCHES SO FAR WITH HEAVY RAIN CONTINUING. SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED TODAY INTO TONIGHT. LATEST GUIDANCE IS HINTING AT PW VALUES BETWEEN 1.5 AND 2.0 INCHES...WHICH COULD LEAD TO THESE STORMS PRODUCING UP TO HALF AN INCH TO AN INCH AN HOUR. THE GREATER THREAT FOR ANY FLOODING LOOKS TO REMAIN NORTH OF THE REGION WHERE THE THREAT OF CONVECTION DEVELOPMENT IS GREATER AND THE FLOW IS WEAKER...THUS ALLOWING FOR SLOWER MOVING STORMS. HOWEVER...AS IS GENERALLY THE CASE...ANY SHOWER OR THUNDERSTORM THAT DOES FORM TODAY COULD LEAD TO MINOR FLOODING IN URBAN AND POOR DRAINAGE AREAS. SUNDAY THROUGH FRIDAY...ALTHOUGH ORGANIZED CONVECTION IS NOT FCST...THERE WILL BE ROUNDS OF SCT TO BKN CONVECTION THAT MIGHT CAUSE MAINLY MINOR URBAN FLOODING. ISOLATED FLASH FLOODING IS NOT OUT OF THE QUESTION THROUGH THIS TIME. && .OKX WATCHES/WARNINGS/ADVISORIES... CT...NONE. NY...NONE. NJ...NONE.
