Several waves of low pressure tracked north along a slow moving cold front that extended from the Gulf Coast to Maine. The combination of this slow moving boundary and a sub-tropical moisture feed aided in the production of heavy rainfall that resulted in moderate to major flooding across portions of Southeast New York.

The episode as NWS OKX wrote it up.
Several waves of low pressure tracked north along a slow moving cold front that extended from the Gulf Coast to Maine. The combination of this slow moving boundary and a sub-tropical moisture feed aided in the production of heavy rainfall that resulted in moderate to major flooding across portions of Southeast New York.

GENERALLY FOLLOWED THE HPC GUIDANCE WITH A BLEND OF THE GFS.
&&
.AVIATION /20Z SUNDAY THROUGH FRIDAY/...
A SLOW MOVING COLD FRONT WILL APPROACH FROM THE WEST...AS A WAVE

THU...SUB-VFR LIKELY IN RAIN.
FRI...SUB-VFR LIKELY TO START...WITH POSSIBLE IMPROVEMENT LATE IN
THE DAY.
&&
.MARINE...
STRONG AND GUSTY SOUTH TO SOUTHEAST FLOW AHEAD OF AN AREA OF LOW
PRESSURE EXPECTED ACROSS THE WATERS TONIGHT. IN FACT...A FEW GUSTS
CLOSE TO GALE FORCE CAN BE ANTICIPATED LATE THIS EVENING AND
OVERNIGHT. THIS IS ESPECIALLY TRUE FOR THE EASTERN WATERS. DO NOT
EXPECT GUSTS TO BE FREQUENT ENOUGH...OR TO LAST FOR LONGER THAN A
FEW HOURS...TO WARRANT A GALE WARNING. THIS WILL NEED TO BE
MONITORED.
THEN WINDS SHIFT AROUND TO THE NORTHWEST AFTER MIDNIGHT FROM WEST TO
EAST AS THE AREA OF LOW PRESSURE MOVES ON BY. THIS LOW AND
ASSOCIATED FRONTAL SYSTEM TRAVERSES WELL TO THE EAST/NORTHEAST BY
MONDAY. GUSTY NW FLOW IS ANTICIPATED THROUGH MONDAY. SCA LIKELY
THROUGH THE DAY.
WINDS TURN TO THE NORTH MONDAY NIGHT AS HIGH PRESSURE MOVES TO THE
NORTH. WINDS LIGHTEN MONDAY NIGHT...AND REMAIN BELOW SCA THRESHOLDS
THROUGH TUESDAY AND WEDNESDAY. WINDS SHIFT TO THE EAST/SOUTHEAST
AHEAD OF ANOTHER STORM SYSTEM ON WEDNESDAY.
AS FOR SEAS...WILL FOLLOW WAVE WATCH III OUTPUT...AND BUOY CLIMO
CLOSELY THROUGH THE PERIOD. SEAS GET RATHER ROUGH TONIGHT...THEN
SLOWLY SUBSIDE MONDAY.
AGAIN...HEADLINES WILL BE NEEDED THROUGH MONDAY...AND INTO MONDAY
NIGHT OVER THE OCEAN.
WITH A PROLONGED PERIOD OF SOUTHEASTERLY WINDS ACROSS THE
WATERS...SEAS ON THE OCEAN WILL CONTINUE TO BUILD THROUGH THURSDAY
NIGHT...AS LOW PRESSURE DEVELOPS ALONG THE EAST COAST AND LINGERS IN
THE VICINITY OF THE FORECAST WATERS INTO SATURDAY. SEAS ON THE OCEAN
WILL BE SMALL CRAFT THROUGH THE PERIOD. WINDS AND GUSTS ARE EXPECTED
TO REMAIN BELOW SMALL CRAFT LEVELS.
&&
.HYDROLOGY...
MOST MODEL SOLUTIONS ARE QUITE WET TODAY...WITH 1 TO 2
INCHES...AND POSSIBLY 3 INCHES IN SPOTS OF QPF EXPECTED...MAINLY
ACROSS INTERIOR LOCATIONS. ACROSS LI AND NYC...1 TO 2 INCHES
POSSIBLE.
THIS ALL DEPENDS OF ACTUAL TOTAL QPF OBSERVED.
IT LOOKS LIKE FLOODING IS QUITE POSSIBLE ACROSS NERN NJ...AND THE
LOWER HUDSON VALLEY. CONFIDENCE IS A LITTLE LOWER ACROSS SRN
CT...BUT IF 2 TO 3 INCHES OF QPF FALLS...A FEW RIVERS AND STREAMS
WILL APPROACH BANKFULL.
AT THIS TIME...THE WALLKILL RIVER AT GARDINER MAY RISE ABOVE
FLOOD STAGE SOMETIME LATER TONIGHT.
I BELIEVE THE SADDLE RIVER AT LODI WILL FALL SHORT OF FLOOD
STAGE...BUT THE RAMAPO RIVER AT MAHWAH WILL COME VERY CLOSE TO
BANKFULL TONIGHT.
THE YANTIC LOOKS TO REMAIN JUST BELOW FLOOD STAGE LATE TONIGHT/EARLY
MONDAY.
AS FOR THE OTHER FAST RESPONDING RIVERS AND STREAMS IN NJ...EXPECT
FLOODING ACROSS MANY OF THESE RIVERS. ONLY AROUND 1 INCH OF QPF IS
NEEDED TO RESULT IN FLOODING ACROSS THIS AREA...WHICH IS EXPECTED.
QPF COULD EXCEED THAT BY QUITE A BIT.
THE HOHOKUS...RAHWAY RIVERS WILL NEED TO BE MONITORED.
MINOR URBAN AND POOR DRAINAGE FLOODING CAN BE EXPECTED ACROSS THE
ENTIRE CWA...INCLUDING THE CITY AND LI.
THE AREA WILL NOT HAVE MUCH TIME TO RECOVER AS THE NEXT SPRING-TYPE
STORM MOVES IN DURING THE THU-FRI TIME PERIOD.

Numerous roads were closed due to flooding throughout the town of Clarkstown in New City.
Runoff from heavy rain caused basement flooding in the town of Yorktown Heights.
The East Village Bridge was closed in Tuxedo Park due to the high flow of the Ramapo River. High water levels caused flooding on the bridge which was closed to traffic and inhibited access into and out of certain parts of town.
