The episode as NWS BUF wrote it up.
Deepening low pressure crossed the Great Lakes region and brought strong winds to the region. The southwest winds were enhanced as they funneled up Lake Erie. A gust of 58 mph was recorded at Dunkirk. Throughout Chautauqua county trees and power lines were downed. Specifically, damage was reported in Portland, French Creek, Sheridan and Dunkirk.

NWS Buffalo, NY wrote its last area forecast discussion before the first event at Nov 30, 6:58 AM EST, 3 hours 32 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BUFFALO NY
658 AM EST TUE NOV 30 2010
.SYNOPSIS...
LOW PRESSURE CENTERED OVER WISCONSIN WILL MOVE SLOWLY TO THE
NORTHEAST AND REACH JAMES BAY BY WEDNESDAY MORNING. VERY MOIST AIR
SURGING AHEAD OF THIS SYSTEM WILL BRING A SOAKING RAIN TO THE REGION
TODAY THROUGH WEDNESDAY. THE RAIN MAY BE EXCESSIVE ACROSS CENTRAL
NEW YORK WHERE FLOODING WILL BE POSSIBLE. THE RAIN WILL END AS A
PERIOD OF WET SNOW FROM WEST TO EAST ON WEDNESDAY ESPECIALLY ACROSS
HIGHER TERRAIN. COLDER AIR WILL FILTER INTO THE REGION FOR THE
SECOND HALF OF THE WEEK WITH A FEW SNOW SHOWERS AND LOCAL LAKE
EFFECT SNOW EAST OF THE LAKES.
&&
.NEAR TERM /THROUGH TONIGHT/...
PERIODS OF MODERATE TO HEAVY RAIN WILL IMPACT MOST OF THE CWA LATER
THIS MORNING THROUGH AT LEAST WEDNESDAY MORNING. THE STEADY RAIN
WILL ALSO BE ACCOMPANIED BY STRONG WIND GUSTS ACROSS PART OF THE
SOUTHERN TIER TODAY...AND ACROSS THE BLACK RIVER VALLEY LATER THIS
AFTERNOON THROUGH TONIGHT.
THE SOUTHERLY FLOW BETWEEN HIGH PRESSURE MOVING OFF THE NEW ENGLAND
COAST AND LOW PRESSURE LIFTING NORTH TOWARD JAMES BAY WILL TRANSPORT
INCREASINGLY MOIST AIR INTO OUR AREA TODAY AND TONIGHT. A COLD FRONT
THAT TRAILS SOUTH OF THIS LOW WILL INTERACT WITH THE FRONT AND SET
THE STAGE FOR A SIGNIFICANT RAIN EVENT.
THE EASTERN EDGE OF THE RAIN SHIELD IS ADVANCING INTO WESTERN NY
EARLY THIS MORNING AND WILL MOVE STEADILY TO THE EAST AS A 70-80
KNOT LOW LEVEL JET SURGES AHEAD OF THE APPROACHING COLD FRONT. THE
AVERAGE OF MODEL GUIDANCE QPF INDICATES A LITTLE OVER THREE QUARTERS
OF AN INCH OF RAIN ACROSS WESTERN NEW YORK TODAY...WITH GENERALLY
LESS THAN ONE HALF INCH EXPECTED ACROSS THE NORTH COUNTRY.
TONIGHT...THE FRONT WILL SLOW UP AS A WEAK LOW MOVES NORTH ALONG THE
BOUNDARY. THIS WILL ALLOW STEADY RAIN TO CONTINUE...ESPECIALLY FROM
THE GENESEE VALLEY TO THE NORTH COUNTRY...WHERE ANOTHER 1.0 TO 1.5
INCHES OF RAIN IS POSSIBLE. AVERAGE BASIN RAINFALL TOTALS FOR TODAY
AND TONIGHT WILL RANGE FROM ABOUT 1.5 TO 2.0 INCHES...TO BE FOLLOWED
BY ADDITIONAL RAIN ON WEDNESDAY.
STRONG WINDS WILL ALSO IMPACT DIFFERENT PARTS OF THE CWA TODAY AND
TONIGHT. THE STRONG SOUTHERLY LOW LEVEL JET WILL BRING GUSTY WINDS
TO PORTIONS OF THE AREA...ESPECIALLY TO AREAS SUSCEPTIBLE TO
DOWNSLOPE WINDS. 850MB WINDS PEAK NEAR 80 KNOTS ACROSS THE SOUTHWEST
CORNER OF NEW YORK FROM MID MORNING THROUGH MIDDAY. THE LATEST NAM
POINT SOUNDINGS STILL SHOW A STEEP INVERSION NEAR THE TOP OF THE
CHAUTAUQUA RIDGE. THE INTENSE LOW LEVEL JET COMBINED WITH THE
FAVORABLE POSITION OF THE INVERSION WILL PRODUCE AN IDEAL SETUP FOR
A DOWNSLOPE WIND STORM ALONG THE LAKE ERIE SHORE TO THE LEE OF THE
CHAUTAUQUA RIDGE. THIS SETUP APPEARS NEARLY IDENTICAL TO THE
DOWNSLOPE WIND EVENT OF DEC 9TH 2009 WHICH PRODUCED A 67 MPH GUST AT
DUNKIRK. SIMILAR TO THIS PAST EVENT...THE THERMODYNAMIC PROFILES
SUGGEST THE STRONGEST WINDS WILL BE IN THE DOWNSLOPE ZONE ALONG LAKE
ERIE...AND NOT ACROSS HIGHER TERRAIN. ACROSS THE HILL TOPS...EXPECT
SLIGHTLY WEAKER WIND GUSTS IN THE 45 TO 50 MPH RANGE ON THE HIGHEST
RIDGES AND ALSO TO THE LEE OF THOSE RIDGES. GIVEN THE SETUP...A HIGH
WIND WARNING REMAINS IN EFFECT FOR CHAUTAUQUA AND SOUTHERN ERIE
COUNTIES MAINLY FOR THE LAKE ERIE SHORE. A WIND ADVISORY REMAINS IN
AFFECT FOR CATTARAUGUS AND WYOMING COUNTIES. LATER THIS AFTERNOON
AND TONIGHT...THE FOCUS FOR THE STRONGER WIND GUSTS WILL SHIFT TO
THE BLACK RIVER VALLEY WHERE THE DOWNSLOPING SOUTHEAST WINDS WILL
CHANNEL UP THE VALLEY.
IN TERMS OF TEMPERATURES...THE LARGE SCALE SOUTHERLY FLOW WILL ALLOW
READINGS TO WARM INTO THE UPPER 40S TO MIDDLE 50S TODAY.
UNSEASONABLY MILD CONDITIONS WILL LAST THROUGH TONIGHT AS THE COLD
FRONT MOVES SLOWLY TO THE EAST.
&&
.SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/...
MODERATE TO HEAVY RAINS WILL ALMOST CERTAINLY BE ONGOING WEDNESDAY
MORNING...ACROSS CENTRAL AND EASTERN NEW YORK AHEAD OF SURFACE COLD
FRONT. ADDITIONAL RAINFALL AMOUNTS COULD EASILY EXCEED AN INCH BASED
ON PRECIPITABLE WATER VALUES STILL SOME 3 TO 4 STANDARD DEVIATIONS
ABOVE NORMAL...STRONG THETA-E CONVERGENCE AND FORCING. RAINS WILL
HOLD ON FOR MOST OF THE DAY...BEFORE TAPERING OFF LATE IN THE DAY
BEHIND THE FRONT.
COLD FRONT SHOULD BE THROUGH WESTERN NEW YORK BY MORNING WITH A
DIMINISHING TREND LIKELY TO BE IN PROGRESS IN THE WAKE OF THE FRONT.
MUCH COLDER AIR FOLLOWING THE FRONT WILL RESULT IN A TRANSITION TO A
MIX OF RAIN AND SNOW ACROSS THE HIGHER ELEVATIONS OF THE SOUTHERN
TIER BY MIDDAY WEDNESDAY AND THIS WILL BECOME LAKE ENHANCED DURING
THE AFTERNOON.
FORECAST FOCUS BY LATE WEDNESDAY THROUGH THURSDAY NIGHT WILL BE THE
POTENTIAL FOR SIGNIFICANT LAKE EFFECT SNOWS. 850 MB TEMPERATURES
DROPPING TO NEAR -10C BY LATE WEDNESDAY AFTERNOON AND WEDNESDAY
NIGHT COMBINED WITH DECENT MOISTURE THROUGH 700 MB WHICH WILL
SATURATE THE DENDRITIC GROWTH ZONE...AND A WELL ALIGNED WEST
SOUTHWEST FLOW WILL FOCUS SIGNIFICANT LAKE PLUMES JUST TO THE SOUTH
OF THE BUFFALO AND WATERTOWN AREAS. SOME FLUCTUATION IN THE LOW
LEVEL FLOW COULD BRIEFLY BRING THE PLUMES NORTHWARD...BUT IN A
PRIMARILY 250 TO 260 FLOW REGIME THE BUFFALO SOUTHTOWNS DOWN INTO
SKI COUNTY AND THE TUG HILL SHOULD BE THE PRIMARY FOCAL POINTS FOR
THE HEAVIEST SNOWS.
LAKE SNOWS SHOULD CONTINUE DURING THURSDAY...BUT WE MAY LIKELY SEE A
DECREASE IN INTENSITY AS THERE IS A SUGGESTION OF ANTICYCLONIC
CURVATURE DEVELOPING. 850 MB TEMPERATURES OF AROUND -9C SHOULD
STILL BE SUFFICIENT FOR LAKE EFFECT...BUT MOISTURE DEPTH LOOKS TO
DECREASE SOMEWHAT...POTENTIALLY ALLOWING THE DENDRITIC GROWTH
ZONE TO BECOME UNSATURATED.
TROUGH LOOKS TO CROSS THE AREA THURSDAY NIGHT...WITH SOME
REINFORCEMENT OF THE LOW LEVEL COLD AIR AND MOISTURE AND WE SHOULD
SEE AN INTENSIFICATION OF THE LAKE SNOWS ON A WEST NORTHWEST FLOW.
WE MAY NEED TO EVENTUALLY HOIST LAKE EFFECT HEADLINES FOR THIS TIME
PERIOD...BUT WITH CURRENT MULTIPLE HEADLINES IN PLACE AND PRIMARY
FORECAST CONCERN AT THIS POINT BEING HEAVY RAINS/FLOODING WE WILL
HOLD OFF WINTER HEADLINES AT THIS TIME AND MENTION POTENTIAL IN
THE HWO.
&&
.LONG TERM /FRIDAY THROUGH MONDAY/...
NW FLOW BEGINS TO WEAKEN ON FRIDAY AS LONG WAVE TROUGH PULLS EAST
ACROSS QUEBEC AND SOME RIDGING BUILDS IN FROM THE OHIO VALLEY. WILL
STILL CARRY HIGH CHC POPS SE OF THE LAKES BUT NOT EXPECTING MUCH
ACCUMS. 850 MB TEMPS AGAIN REMAIN MARGINAL...IN -8 TO -10C
RANGE...SO NOT ESPECIALLY COLD...PROB MID 30S OR SO FOR MAXES.
WEEKEND THEN APPEARS RATHER TRANQUIL AND COLD...BUT WE HAVE A
PATTERN CHANGE AS THE STRONGLY NEGATIVE NAO WILL FORCE THE NEXT LOW
SOUTH...TAKING IT ON A TRACK FROM MINN TO THE OHIO VALLEY AND
EVENTUALLY OFF THE MID ATLANTIC COAST. THIS WOULD KEEP THE SNOW TO
OUR SOUTH...MOSTLY...AT LEAST PER 12Z ECMWF...BUT GFS TAKES IT
CLOSER. FOR NOW...WILL CARRY CHC POPS FOR LIGHT SNOW SRN TIER SAT NT
AND SUN AS THEY MAY GET BRUSHED. ELSEWHERE...WEAK NORTH TO NORTHEAST
FLOW NOT CONDUCIVE TO LK EFFECT SO MINIMAL POPS BOTH DAYS. FLOW
TURNS NW AGAIN MONDAY SO WILL RE-INSERT CHC POPS SE OF THE LAKES.
CONFIDENCE IN WEEKEND FORECAST IS LOW. TEMPS WILL REMAIN SLIGHTLY
BELOW NORMAL THROUGH THE LONG RANGE PERIOD.
&&
.AVIATION /12Z TUESDAY THROUGH SATURDAY/...
LOW PRESSURE CENTERED OVER LAKE SUPERIOR WILL LIFT NORTH TOWARD
JAMES BAY TONIGHT. A COLD FRONT TRAILING SOUTH OF THE LOW WILL
APPROACH WESTERN NEW YORK AROUND 06Z...THEN STALL OVER CENTRAL BY
12Z WEDNESDAY AS A SECOND LOW MOVES NORTH ALONG THE BOUNDARY.
VERY MOIST AIR SURGING AHEAD OF THE APPROACHING COLD FRONT WILL
CAUSE RAIN TO SPREAD EAST ACROSS THE AREA THIS MORNING. RAIN WILL
BECOME MODERATE TO HEAVY AT TIMES DURING THE AFTERNOON THROUGH
TONIGHT.
MAINLY VFR CONDITIONS WILL LOWER TO MVFR AS THE RAIN BECOMES MORE
STEADY LATER THIS MORNING AND DURING THE AFTERNOON. WHILE MODEL
GUIDANCE IS SHOWING IFR CIGS DEVELOPING DURING THE AFTERNOON...THE
TENDENCY FOR DOWNSLOPING SOUTHERLY WINDS IS TO KEEP CIGS ABOVE IFR.
EXPECT THIS TREND TO CONTINUE UNTIL THE WINDS SWITCH TO THE
SOUTHWEST BEHIND THE FRONT...CAUSING CIGS TO LOWER TO IFR LATE
TONIGHT AT ALL TAF SITES WEST OF KART.
LLWS WILL PREVAIL FIRST HALF OF TODAY AS A 70-80 KNOT LOW LEVEL JET
PROPAGATES INTO WESTERN NY. LATER THIS MORNING...THE WINDS WILL
START TO MIX DOWN TO THE SURFACE WITH GUSTS IN THE 20-35 KNOT
RANGE...EVEN HIGHER ALONG THE LAKE ERIE SHORE WHERE DOWNSLOPE WINDS
MAY BRING LOCAL GUSTS OF 40-50 KNOTS.
OUTLOOK...
WEDNESDAY...IFR/MVFR WITH RAIN ENDING AS A PERIOD OF WET SNOW FROM
WEST TO EAST.
WEDNESDAY NIGHT...MVFR WITH SCATTERED SNOW SHOWERS. LOCAL LIFR EAST
OF LAKES ERIE AND ONTARIO IN LAKE EFFECT SNOW.
THURSDAY...GENERALLY MVFR WITH SCATTERED SNOW SHOWERS AND LOCAL LIFR
IN LAKE EFFECT SNOW EAST OF THE LAKES.
FRIDAY...GENERALLY VFR EXCEPT MVFR/IFR IN LOCAL LAKE SNOWS SOUTHEAST
OF THE LAKES.
SATURDAY...MAINLY VFR.
&&
.MARINE...
THE PRESSURE GRADIENT BETWEEN HIGH PRESSURE MOVING OFF THE NEW
ENGLAND COAST AND LOW PRESSURE LIFTING NORTH ACROSS THE UPPER
MIDWEST WILL GENERATE INCREASING SOUTH TO SOUTHEAST WINDS TODAY. THE
WINDS WILL BE THE STRONGEST ALONG THE LAKE ERIE SHORE WHERE LOCAL
DOWNSLOPING OFF THE HIGHER TERRAIN WILL BRING GALE FORCE WINDS.
ELSEWHERE EXPECT WINDS TO INCREASE TO SMALL CRAFT ADVISORY CRITERIA
EXCEPT FOR THE WESTERN END OF LAKE ONTARIO WHICH IS NOT FAVORED FOR
STRONGER WINDS IN SOUTHEAST FLOW. WINDS WILL DIMINISH TONIGHT
AS A SLOW MOVING COLD FRONT MOVES OVERHEAD AND THE PRESSURE GRADIENT
RELAXES.
