The episode as NWS ALY wrote it up.
Above normal to record precipitation of 5 to 9 inches occurred in April across a large area of New York State. There was above normal snowpack across the higher elevations of the Adirondacks with snow depths at least a foot above normal. A warm front lifted northward across the area on Tuesday, April 26th, ushering in a warm and humid airmass. Temperatures rose into the 70s and 80s across the area on Tuesday and again on Wednesday, April 27th (15 to 25 degrees above normal). In addition, overnight lows were mild.
An area of heavy showers and embedded thunderstorms accompanied the warm front as it moved through on Tuesday, April 26th, impacting areas mainly north and west of the Capital District. The boundary became stationary near the Saint Lawrence River Valley and northern New England. A disturbance in the upper levels of the atmosphere and an area of low pressure moving towards the Great Lakes Region focused another round of showers and thunderstorms that impacted the western and central Mohawk Valley, Adirondack region, and the Upper Hudson River Valley including the Lake George Region late Wednesday afternoon into the early evening, April 27th. Yet another wave of low pressure moved into the eastern Great Lakes Region Thursday morning, April 28th. This low intensified as it approached and had strong upper level support favorable for strong to severe thunderstorms. Thunderstorms producing severe weather and very heavy rainfall moved over already saturated ground to the north and west of the Capital District during the morning hours.
The combination of several rounds of heavy rainfall from convection, rapid snowmelt due to the warm temperatures and above normal soil moisture led to increased runoff and rapid river rises. Widespread flooding of rivers, streams and creeks occurred resulting in road closures and flooding of properties. On Thursday, April 28th, an earthen dam failed sending water, dirt and debris from Lewiston Pond on Route 9 at Brower Road into the Longberry Lake which is Saratoga Springs' drinking water supply (no health threat report). Many record crests occurred on rivers, creeks and streams throughout the upper Hudson and upper Mohawk basins.
The following river points reached record levels:|Hudson River at North Creek in Warren County, Fort Edwards in Washington/Saratoga counties and Schuylerville in Saratoga/Washington counties.|Stillwater Reservior at Beaver River in Herkmier County.|Great Sacandaga River at Conklingville and Stewarts Bridge near Hadley in Saratoga County.|West Canada Creek near Wilmurt and Kast Bridge in Herkimer County.|Indian River near Indian Lake in Hamilton County.|Hinkley Reservior at Hinkley in Herkimer County.
As a result of the flooding, states of emergency were declared in Indian Lake and Long Lake Hamilton County, Town of Johnsburg Warren/Hamilton Counties, Town of Chester Warren County, and in the Village of Middleville Herkimer County.
The following school districts were closed on April 29th due to the flooding: Indian Lake and Long Lake in Hamilton County and Johnsburg in Warren County.
The New York State Canal Corporation delayed the opening of the New York State Canal System due to high water and excessive flows.
Disaster damage estimates from the flooding and some severe weather in April 2011 total $2,622,025 for the following counties in east central New York.|Hamilton: $481,000|Herkimer: $571,800|Saratoga: unknown|Warren: $676,225|Washington: $53,000
On June 10th, The U.S. Department of Homeland Security's Federal Emergency Management Agency (FEMA) announced that federal disaster assistance had been made available to the state of New York to supplement state and local recovery efforts in the area struck by storms, flooding, tornadoes, and straight-line winds during the period of April 26 to May 8, 2011. This includes the counties of Hamilton, Herkimer, and Warren in east central New York.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ALBANY NY
524 PM EDT WED APR 27 2011
.SYNOPSIS...
A WARM AND HUMID EVENING IS ON TAP...ALONG WITH THE POSSIBILITY OF A
PASSING SHOWER OR THUNDERSTORM. A COLD FRONT WILL APPROACH FROM THE
WEST LATER TONIGHT AND CROSS THE REGION THURSDAY AFTERNOON AND
EVENING...ACCOMPANIED SHOWERS AND THUNDERSTORMS. WITH THE PASSAGE OF
THIS COLD FRONT...A MORE SEASONABLE AIRMASS WILL BE USHERED INTO THE
REGION AS WE HEAD INTO THE WEEKEND...WITH FAIR CONDITIONS RETURNING
BY SATURDAY.
&&
.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
AS OF 5 PM EDT...ISOLATED TO SCATTERED SHOWERS AND EMBEDDED TSTMS
HAVE DEVELOPED ACROSS THE EXTREME SE CATSKILLS INTO NORTHERN
NJ...AND ARE HEADING RAPIDLY N. WE EXPECT THESE SHOWERS AND PERHAPS
SOME THUNDER TO CONTINUE MOVING N...AND AFFECTING AREAS ALONG AND
WEST OF THE HUDSON RIVER THROUGH THIS EVENING...INCLUDING THE
WESTERN MOHAWK VALLEY AND ADIRONDACKS. FURTHER E...THE CHC FOR
SHOWERS WILL BE LESS ACROSS WESTERN NEW ENGLAND THROUGH EARLY THIS
EVENING...WITH THE BEST CHC ACROSS PORTIONS OF SOUTHERN VT.
THEN...THE TAIL END OF A POTENT SHORTWAVE CURRENTLY MOVING N THROUGH
THE EASTERN GREAT LAKES WILL APPROACH FROM THE WEST LATER THIS
EVENING. ALONG AND AHEAD OF THIS FEATURE...EXPECT A BAND OF SHOWERS
AND THUNDERSTORMS TO GRADUALLY MOVE E/NE ACROSS THE
REGION...AFFECTING THE WESTERN DACKS/MOHAWK VALLEY AND POSSIBLY
EASTERN CATSKILLS BETWEEN 9 PM AND MIDNIGHT...AND MANY AREAS FROM
THE CAPITAL DISTRICT N AND W BY...AND AFTER MIDNIGHT. SHORT TERM
NUMERICAL GUIDANCE...ESPECIALLY THE HRRR...INDICATES THE POTENTIAL
FOR THE TAIL END OF THIS SHORTWAVE TO STALL ACROSS WESTERN PORTIONS
OF THE REGION AFTER MIDNIGHT...WHILE THE NEXT WAVE RIDES NORTH.
SHOULD THIS OCCUR...THE POTENTIAL FOR MULTIPLE WAVES OF HEAVY RAIN
AND TSTMS WOULD EXIST ACROSS THE ALREADY WATERLOGGED WESTERN
ADIRONDACKS. WE HAVE ISSUED A FLASH FLOOD WATCH ACROSS MUCH OF THE
NW PORTIONS OF THE REGION DUE TO THIS POSSIBILITY. ABUNDANT
MOISTURE...WITH PWAT/S EXCEEDING +4 SD AND STRONG MOISTURE
CONVERGENCE COULD FOCUS VERY HEAVY RAINFALL WHERE THIS
AFOREMENTIONED BAND STALLS.
AT THIS TIME...HAVE HELD OFF ON FFA ISSUANCE FOR THE MID HUDSON
VALLEY REGION...AND WESTERN NEW ENGLAND...WHERE RAINFALL AMTS HAVE
BEEN MUCH LESS RECENTLY...AND THE POTENTIAL FOR REPEATED WAVES OF
HVY RAINFALL APPEARS LESS.
GIVEN THE STRENGTHENING MID LEVEL WIND FIELDS...WILL HAVE TO ALSO
WATCH FOR POSSIBLE STRONG WINDS WITHIN ANY DEEPER CONVECTIVE
ELEMENTS OVERNIGHT...WITH THE BEST POTENTIAL ACROSS NW AREAS.
OVERNIGHT MINS SHOULD REMAIN QUITE WARM...AND HAVE TRENDED CLOSER TO
THE MET MOS...WITH MINS GENERALLY REMAINING IN THE MID TO EVEN UPPER
60S IN SOME HUDSON RIVER VALLEY AREAS...WITH MOST AREAS REMAINING
ABOVE 60.
&&
.SHORT TERM /6 AM THURSDAY MORNING THROUGH SATURDAY/...
THURSDAY...POTENTIALLY VERY ACTIVE MORNING...WITH POSSIBLE CLUSTERS
OF CONVECTION AFFECTING WESTERN AREAS FIRST...WITH SHOWERS/TSTMS
POSSIBLY BECOMING MORE ELONGATED INTO A LINE DURING THE LATE MORNING
AND EARLY AFTERNOON HOURS. GIVEN THE STRONG LOW AND MID LEVEL WIND
FIELDS...ANY DEEPER CONVECTIVE ELEMENTS COULD EASILY TRANSLATE GUSTY
WINDS TO THE SURFACE...IF NOT DAMAGING. SO...AT THIS TIME...IT
APPEARS THAT A HIGH SHEAR/LOW CAPE ENVIRONMENT WILL OCCUR...WITH
BOWING CONVECTIVE SEGMENTS BEING THE MAIN MODE OF ANY SEVERE.
HOWEVER...SHOULD MORE BREAKS IN THE CLOUDS DEVELOP PRIOR TO THE COLD
FRONT...MORE DISCRETE THUNDERSTORM CELLS COULD DEVELOP...WHICH COULD
THEN EVOLVE INTO SUPERCELLS. THE BEST CHANCE FOR SEVERE WOULD APPEAR
TO BE DURING THE MORNING HOURS ACROSS WESTERN PORTIONS OF THE
REGION...THEN FROM LATE MORNING THROUGH EARLY AFTERNOON ACROSS THE
HUDSON RIVER VALLEY REGION...AND EARLY TO MID AFTERNOON ACROSS
WESTERN NEW ENGLAND. EVEN OUTSIDE OF ANY CONVECTION...WILL NEED TO
CLOSELY WATCH UPSTREAM OBS FOR POTENTIALLY STRONG GRADIENT WINDS
GIVEN THE POTENTIAL RAPID DEEPENING OF THE SFC LOW...WITH THE STRONG
HIGH REMAINING WELL TO OUR E. THIS COULD LEAD TO WIND ADVISORY LEVEL
WINDS...IF NOT STRONGER ACROSS PORTIONS OF THE REGION PRIOR TO...AND
POSSIBLY IMMEDIATELY BEHIND THE COLD FRONTAL PASSAGE. ASSUMING WE
GET INTO A BRIEF PERIOD OF GUSTY S TO SW WINDS...MAX TEMPS SHOULD
REACH 75-80 ACROSS THE HUDSON RIVER VALLEY REGION WITH 70-75 ACROSS
MUCH OF WESTERN NEW ENGLAND...WHILE THE WESTERN DACKS GENERALLY
REACH THE 60S.
THU NT/FRI...SOME SHOWERS MAY LINGER EARLY ACROSS EASTERN AREAS.
OTHERWISE...EXPECT A LULL IN THE PRECIP...BEFORE ISOLATED TO
SCATTERED RAIN SHOWERS REDEVELOP FROM NW TO SE TOWARD FRIDAY MORNING
AHEAD OF THE UPPER LEVEL TROUGH. AS THIS TROUGH SWEEPS E FRI
MORNING...SCATTERED SHOWERS SHOULD AFFECT MUCH OF THE CENTRAL AND
NORTHERN PORTIONS OF THE REGION FRI MORNING...WITH THE POSSIBILITY
OF SOME RUMBLES OF THUNDER AS WELL AS A MID LEVEL COLD POOL MOVES
ACROSS. OTHERWISE...GENERALLY FOLLOWED CLOSE TO MET MOS DURING THIS
PERIOD FOR TEMPS.
FRI NT/SAT...SOME LINGERING SHOWERS OF RAIN/SNOW WILL BE POSSIBLE
ACROSS THE SOUTHERN ADIRONDACKS FRI NT. THEN...EXPECT MOSTLY SUNNY
SKIES FOR SAT...WITH TEMPS GENERALLY REACHING THE MID OR UPPER 60S
IN VALLEYS...AND 50S ACROSS HIGHER ELEVATIONS.
&&
.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
HPC GUIDANCE. THE PERIOD BEGINS WITH A RIDGE OF HIGH PRESSURE FROM
GREENLAND THROUGH LABRADOR AND NEW ENGLAND TO THE CAROLINAS COAST
GIVING WAY TO A WARM FRONT WHICH WILL BRING A DECENT CHANCE OF RAIN
TO OUR AREA FOR THE START OF THE WEEK. THE FRONT WILL BE ASSOCIATED
WITH WEAK LOW PRESSURE WHICH WILL TRACK SLOWLY THROUGH SOUTHEAST
ONTARIO AND SOUTHERN QUEBEC MONDAY THROUGH TUESDAY.
A LACK OF MID-LEVEL MOMENTUM WILL HELP SLOW THE FRONT...KEEP
CLOUDINESS PLENTIFUL AND CAP INSTABILITY FOR THE EARLY-WEEK
PERIOD...WITH A CHANCE OF SHOWERS MONDAY NIGHT THROUGH TUESDAY
NIGHT. WITH A WEAK COASTAL LOW NEAR NEW JERSEY WEDNESDAY NOT
EXPECTED TO DEVELOP...THE FRONT SHOULD CONTINUE TO MOVE ON...AND THE
MID-WEEK PERIOD WILL BECOME BASICALLY DRY AS HIGH PRESSURE MOVES
SLOWLY IN FROM THE WEST.
DAYTIME HIGH TEMPERATURES WILL START OFF SEVERAL DEGREES ABOVE
NORMAL...BUT THEN PROGRESS TO SEVERAL DEGREES BELOW NORMAL BY
WEDNESDAY. DUE TO THE WARM FRONT AND CLOUDINESS...OVERNIGHT LOWS
WILL BE SEVERAL DEGREES ABOVE NORMAL SUNDAY NIGHT THROUGH WEDNESDAY
NIGHT.
&&
.AVIATION /21Z WEDNESDAY THROUGH MONDAY/...
UNSETTLED WEATHER WILL CONTINUE AFFECT ALL TERMINALS WITH VFR FLIGHT
CONDITIONS DETERIORATING TO MVFR THIS EVENING AS SHOWERS AND TSTMS
MOVE OVER THE REGION.
ISOLATED SHOWERS WILL DEVELOP THIS AFTERNOON...SO HAVE INCLUDED VCSH
AT ALL TERMINALS. ISOLATED TSTMS MAY DEVELOP LATE IN THE AFTERNOON
INTO EVENING...HAVE THEREFORE INCLUDED CB AT KPOU/20Z AND
KALB/KGFL/23Z. BETTER CHC OF PRECIP AND CB OVERNIGHT INTO THURSDAY
MORNING AS A COLD FRONT APPROACHES. AFTER MIDNIGHT...CONDITIONS WILL
DETERIORATE TO IFR AND BE SLOW TO IMPROVE TO MVFR THURSDAY MORNING.
WINDS WILL CONTINUE FROM THE SOUTH THROUGH THURSDAY MORNING. WIND
SPEEDS EXPECTED 9-14 KTS THIS AFTERNOON WITH GUSTS 15-25 KTS. GUSTS
EXPECTED TO SUBSIDE OVERNIGHT...BUT SUSTAINED WINDS WILL CONTINUE AT
5-10 KTS. WITHIN SHOWERS AND TSTMS WIND GUSTS OF 30+KTS POSSIBLE.
LATE THURSDAY MORNING...SOUTHERLY WINDS WILL STRENGTHEN WITH GUSTS
RETURNING. LLWS COULD BE AN ISSUE NEAR COLD FRONTAL PASSAGE LATE
THURSDAY MORNING.
