The episode as NWS ALY wrote it up.
An occluded, warm, and cold frontal complex moved across the Great Lakes on November 9. They moved into central New York late in the day on November 9, and through eastern New York and western New England overnight. At daybreak on November 10, the system was off the Atlantic coast. About an inch and a half of rainfall occurred on the night of November 9 in the southern Adirondacks and western Mohawk Valley. This resulted in enough runoff to send Canajoharie Creek over its flood stage early on the morning of November 10.

NWS Albany, NY wrote its last area forecast discussion before the first event at Nov 10, 3:47 AM EST, 3 hours 13 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ALBANY NY 347 AM EST THU NOV 10 2005 .SYNOPSIS...LOW PRESSURE WILL CONTINUE TO MOVE NORTHEAST INTO NORTHEASTERN QUEBEC TODAY. AN UPPER LEVEL DISTURBANCE IN THE BRISK NORTHWESTERLY FLOW WILL MOVE ACROSS EASTERN NEW YORK AND WESTERN NEW ENGLAND IN THE LATE MORNING AND AFTERNOON. IT WILL BE COLD AND WINDY TODAY. LAKE EFFECT RAIN AND SNOW SHOWERS WILL OCCUR MAINLY NORTH AND WEST OF ALBANY THURSDAY AFTERNOON. LAKE ENHANCED SNOW SHOWERS WILL CONTINUE FRIDAY MORNING FOR THE SOUTHERN ADIRONDACKS...CENTRAL MOHAWK VALLEY AND LOWER CATSKILLS. HIGH PRESSURE WILL BUILD IN FROM THE TENNESSEE VALLEY FRIDAY WITH DRY WEATHER THROUGH MOST OF THE WEEKEND. LARGE SCALE OVERVIEW...500 MB MERIDIONAL FLOW DOMINATES THE LOWER 48 THIS MORNING WITH A TROUGH OVER THE ERN THIRD OF NORTH AMERICA...A RIDGE OVER WRN CANADA AND THE NORTHERN ROCKIES...AND A CUTOFF LOW IMPACTING CA AND THE GREAT BASIN (QUASI-REX BLOCK SIGNATURE THERE). THE WATER VAPOR IMAGERY THIS MORNING SHOWS THE COLD CORE CUTOFF LOW SOUTH OF HUDSON BAY ASSOCIATED WITH THE LONG WAVE TROUGH OVER THE MIDWEST...GREAT LAKES REGION AND NORTHEAST. PLENTY OF UPPER LEVEL JET ENERGY IS SWINGING THROUGH THE BASE OF THE LONG WAVE TROUGH FORCING A COLD FRONT ACROSS THE NORTHEAST EARLY THIS MORNING. THE REGION WILL STAY IN CYCLONIC FLOW ALOFT AND AT THE SURFACE FOR THE NEXT 24-36 HOURS...BEFORE A HIGH AMPLITUDE RIDGE EXTENDING FROM THE LOWER MS RIVER VALLEY TO HUDSON BAY MOVES EASTWARD OVER THE EAST COAST FOR THE WEEKEND. && .SHORT TERM (TODAY THROUGH SATURDAY)... ALY CLIMATOLOGICALLY HAS 3 THUNDERSTORM DAYS EVERY 10 YEARS. ALY HAS NOW HAD 2 IN LESS THAN A WEEK LAST NOVEMBER...ALY HAD ONE ON THANKSGIVING (NOV 25), SO WE HAVE HAD 3 IN 2 YEARS IT HAS BEEN THAT KIND OF YEAR IN THE ALY FCST AREA WITH WILD AND CHAOTIC WEATHER STRETCHES. ELEVATED CONVECTION AND CG LTG STRIKES WERE SPORADIC ACROSS THE ENTIRE ALY FCST AREA AHEAD AND BEHIND THE WARM FRONT. MOST OF THE ENTIRE AREA SLIPPED INTO A MINI WARM SECTOR (RAIN CLUTTERED...SO NOT MUCH SIGNIFICANT WARMING...ESP THE NRN HLF OF THE CWA)...AS THE TRIPLE POINT TO SYSTEM REACHED APPROX KMSS AT 03Z. THE COLD FRONT TO THE SYSTEM ZIPPED ACROSS ERN NY WRN NEW ENGLAND AND ALL THE PCPN MOVED EAST BTWN 06Z AND 08Z. TODAY...A 500 MB SHORTWAVE TROUGH/SECONDARY COLD FRONT WILL MOVE ACROSS THE FCST AREA IN THE LATE MORNING INTO THE EARLY PM. THIS DISTURBANCE WILL TAP SOME MOISTURE FROM THE ERN GREAT LAKES. STRONG H850 COLD AIR ADVECTION WILL BE OCCURRING WITH TEMPS AT THAT LEVEL FALLING TO -6C TO -10C BY 18Z FROM NW TO SE OVER THE FCST AREA. IT WILL BE BLUSTERY WITH H850 WINDS W/NW AT 35-45 KNOTS. SFC WINDS WILL GENERALLY BE 15-30 MPH WITH GUSTS 35 TO 45 MPH...ESPECIALLY OVER TERRAIN GREATER THAN 1500 FT. WE FEEL HIGH TEMPS TODAY WILL PEAK AROUND NOONTIME AND THEN START TO FALL OFF IN THE PM. SOME COMPRESSIONAL/ADIABATIC HEATING OFF THE CATSKILLS AND ADIRONDACKS MAY INHIBIT AN EARLY DROP OFF IN THE VALLEYS FOR AN HOUR OR TWO. WE HAVE TRIED TO KEEP THE CHANCE POPS FROM ALY NORTH AND WEST WITH LIKELY VALUES OVER THE CNTRL MOHAWK VALLEY...SRN ADIRONDACKS AND THE ERN CATSKILLS. UPSLOPING FACING TERRAIN EAST OF ALY ALSO MAY SEE SOME -SHRA/-SHSN. THE BOUNDARY LAYER BEGINS TO COOL DOWN CONSIDERABLY AFTER 18Z...SO TOWARDS SUNSET A TRANSITION FROM A RAIN/SNOW MIX IN THE VALLEYS WILL GO TO ALL SNOW. ELEVATIONS GREATER THAN 1500 FT SHOULD START TO SEE SOME WET SNOW IN THE LATE AM/EARLY PM WITH SOME VERY LIGHT ACCUMULATIONS. LATE TODAY AND OVERNIGHT... THE LAKE EFFECT POTENTIAL PICKS UP LATE IN THE DAY WITH A 290 DEGREE TRAJECTORY AND BROAD CYCLONIC FLOW. THE LAKE ONTARIO TEMP IS AROUND 10C. H850 TEMPS WILL BE AROUND -10C OR SO LATE IN THE DAY/EARLY IN THE EVENING. DELTA T OF 20C IS GOOD FOR LAKE POTENTIAL. THE INVERSION OFF THE KSYR SOUNDING FROM THE NAM AND GFS STAYS RIGHT AROUND 8-9KFT EARLY ON. WHAT IS A NEGATIVE FOR WIDESPREAD ORGANIZED SINGLE OR MULTI-BANDS IS THAT THE INVERSION LOWERS TO ABOUT 5KFT QUICKLY AROUND 00Z FROM BOTH MODELS. ALSO...BOTH MODELS ARE ADVERTISING SYNOPTIC DECENT/SUBSIDENCE KICKING BTWN 00Z-06Z. WE WILL KEEP SNOW SHOWERS WEST OF ALY OVERNIGHT. UP TO A FEW INCHES IS POSSIBLE IN A FEW LOCALES. FROM THE HUDSON VALLEY EAST...IT WILL BE A VERY COLD NIGHT WITH THE CORE OF THE COLDEST AIR AT H850(TEMPS -10C TO -13C) SETTLING OVER THE REGION. H500 VALUES WILL BE IN THE -25C TO -30C RANGE. JUST ABOUT THE ENTIRE CWA WILL BE IN THE 20S...WITH TEENS OVER THE DACKS. WE WENT CLOSER THE COLDER ETAMOS VALUES HERE. FRIDAY...ANTICYCLONIC FLOW KICKS IN TO END THE LAKE EFFECT POTENTIAL. WE CUT THE POPS AND PCPN FROM THE PREVIOUS FORECAST WITH SFC HIGH PRESSURE BUILDING IN FROM THE TN VALLEY. PARTLY SUNNY/MOSTLY SUNNY CONDITIONS WILL PREVAIL...HOWEVER TEMPS WILL STILL RUN ABOUT 3-5 DEGREES BELOW NORMAL WITH MID TO UPPER 40S IN THE VALLEY AND 30S TO LOWER 40S OVER THE HILLTOWNS AND MTNS...AS THE UPPER LEVEL TROUGH LIFTS EAST. FRI NIGHT...AN IDEAL RADIATIONAL COOLING NIGHT WITH A BROAD SFC HIGH BUILDING NORTH FROM THE MID ATLANTIC REGION. CLEAR SKIES...LIGHT TO CALM WINDS WILL ALLOW TEMPS TO TUMBLE. SOME H850 WARM AIR ADVECTION WILL BE OCCURRING. THE NAM ADVERTISED MORE CLOUD COVER THAN THE GFS. IT IS LIKE A FLIP FLOP FROM THE PREVIOUS NIGHT AND WE WENT CLOSER TO THE GFSMOS VALUES. SATURDAY...A HIGH AMPLITUDE 500 MB RIDGE BUILDS OVER THE EAST COAST. IT SHOULD BE A LOVELY SATURDAY WITH HIGH TEMPS RISING BACK TO NORMAL TO ABOVE NORMAL LEVELS. H850 TEMPS RISE BACK TO AROUND 3-5C WITH THE RETURN FLOW OF THE SFC HIGH THE MID ATLANTIC COAST. A BLEND OF THE ETA/GFS MOS VALUES WAS USED HERE. && .LONG TERM (SATURDAY NIGHT THROUGH WEDNESDAY)... THE MILDER WEATHER CONTINUES SAT NIGHT INTO SUN. A COLD FRONT WILL DROP SOUTHEAST FROM THE ST LAWRENCE VALLEY...ERN GREAT LAKES AND THE MIDWEST IN THE PM. THE ONLY CHANGES MADE TO SUNDAY WERE TO BUMP UP TEMPS A CATEGORY DUE TO THE H850 TEMPS RISING TO +8-12C PER COORD WITH BTV WFO AND TO BACK THE SLIGHT CHANCE/LOW CHANCE OF -SHRAS UNTIL THE PM. MON-WED...STORM SYSTEMS CONTINUE TO FOLLOW AN OHIO VALLEY TRACK PATTERN SIMILAR TO THE PAST WEEK OR SO WITH A PREDOMINANT -PNA/+NAO IN THE MEAN. THIS EQUATES TO SOME UNSETTLED WEATHER FOR THE STRETCH WITH A COUPLE OF COLD FRONTAL PASSAGES MON AND WED WITH CYCLONIC FLOW IN BETWEEN. NO CHANGES TO THE SUN NIGHT-WED PORTION OF THE FORECAST. && .AVIATION...LOCAL IFR CONDITIONS IN BR/HZ EARLY THIS MORNING OTHERWISE VRF.

RH VALUES WILL GENERALLY BE 55-75 PERCENT...EXCEPT IN ANY LAKE ENHANCED SHOWERY ACTIVITY...WHERE RH VALUES WILL BE 80-100 PERCENT. THE WINDS WILL SUBSIDE THURSDAY NIGHT AND THE LAKE EFFECT ACTIVITY WILL BEGIN TO DIMINISH OVERNIGHT. && .HYDROLOGY...NO HYDRO PROBLEMS ANTICIPATED THE NEXT SEVERAL DAYS. THE HEAVIEST RAINFALL FROM THE SYSTEM YESTERDAY WAS NORTH OF THE CAPITAL REGION. GENERALLY ONE TO TWO INCHES FELL THERE. FROM THE CAPITAL REGION SOUTH A QUARTER TO THREE QUARTERS OF AN INCH WAS COMMON. THE RADAR ESTIMATED TWO TO THREE INCHES OVER SRN HERKIMER...NW FULTON AND SW HAMILTON. SOME WITHIN BANK RISES HAPPENED...BUT NO FLOODING OCCURRED OR WAS REPORTED. THE PCPN THE NEXT 24 HOURS WILL BE LIGHT AND THE LAKE EFFECT VARIETY.
