The episode as NWS BGM wrote it up.
A low pressure system moved from the Southern Plains to the Ohio Valley before tracking across Southern Pennsylvania to Southern New England. Snow overspread much of the area on the evening of the 15th, before mixing with and changing over to sleet and freezing rain. The highest snowfall totals occurred across the Northern Finger Lakes, Western Mohawk Valley and Tug Hill Plateau, where persistent wrap around snow occurred as the storm redeveloped into a major winter storm on the East Coast. In these areas, snowfall amounts ranged between 10 and 18 inches.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BINGHAMTON NY
648 PM EST SAT DEC 15 2007
.SYNOPSIS...
LOW PRESSURE WILL MOVE OUT OF THE TENNESSEE VALLEY TONIGHT...THEN
REDEVELOP INTO A STRONG WINTER STORM ON THE EAST COAST SUNDAY. THE
STORM MOVES TO NEW ENGLAND BY MONDAY MORNING. A VARIETY OF WINTER
PRECIPITATION WILL OVERSPREAD CENTRAL NEW YORK AND NORTHEAST
PENNSYLVANIA TONIGHT AND SUNDAY...THEN TAPER OFF TO SNOW SHOWERS
MONDAY. SIGNIFICANT SNOW AND SLEET ACCUMULATIONS ARE LIKELY OVER
NORTH CENTRAL NEW YORK...WITH MAINLY SLEET AND FREEZING RAIN
ACROSS NORTHERN PENNSYLVANIA. HIGH PRESSURE BUILDS INTO THE AREA
TUESDAY FOR A QUIETER MIDDLE PART OF THE WEEK.
&&
.NEAR TERM /THROUGH SUNDAY/...
LARGE TROF AND ASSOCIATED SFC LOW PRESSURE WAS STARTING TO GET
IT/S ACT TOGETHER OVER THE LOWER MISSISSIPPI VALLEY TODAY. FEEL
THAT THE 12Z NAM/GFS HAVE INITIALIZED WELL...ALTHOUGH WITH TIME
THERE ARE SOME DIFFERENCES IN HANDLING THE ENERGY TRANSFER TO
COASTAL LOW WITH GFS STILL INSISTING THINGS A LITTLE FURTHER
EAST...FASTER AND COOLER. FROM THE LATEST SATL AND RADAR TENDENCIES
OF THIS STORM...IT IS BECOMING MUCH CLEARER TODAY THAT THE
PRIMARY LOW WILL DOMINATE THE DAY. THE TRACK OF THE UPPER LEVEL
CUTOFF LOW PRESSURE MOVING BASICALLY ACROSS THE HEART OF THE
FORECAST AREA TOMORROW AFTERNOON... DOES NOT BODE WELL FOR A MAJOR
SNOWSTORM. INSTEAD...WE WILL DEAL WITH HIGHLY VARIABLE WINTER WX
CONDITIONS. IN FACT...WE/LL PROBABLY SEE TWO SERVINGS OF SNOW OVER
THE CWA...WITH THE MESS IN THE MIDDLE.
AS THE MAIN SYSTEM LIFTS TO OUR WEST...PRECIPITATION WILL BREAK
OUT ON NOSE OF STRONG LLJ EARLY THIS EVENING. COLD AIRMASS OVER
THE AREA WILL ALLOW THIS TO START OFF AS A FLUFFY SNOWFALL...BEFORE
WARMING ALOFT RIPS THROUGH THE REGION AND SLEET/FREEZING RAIN
DRAWS NORTH INTO THE SOUTHERN TIER BY DAYBREAK. WE/RE THINKING A
QUICK SHOT OF 2-5 INCHES OF SNOW BEFORE ANY CHANGEOVER FOR MOST
AREAS. TRICKIEST AREA WILL BE NEPA WHERE NAM BRINGS A SIG AMOUNT
OF QPF INTO THE POCONOS OVERNIGHT. THE MODEL IS GRABBING ONTO THE
MOISTURE ASSOCIATED WITH THE CONVECTION OVER GA/SC. GFS SHUNTS IT
EAST. BUFKIT SOUNDINGS LEAN TOWARD FZRA. IT IS VERY HARD TO GET
HALF INCH ACCRETIONS OF ICE...BUT THIS IS AS CLOSE AS YOU GET.
FOR NOW WILL HOLD THE LINE ON AN ADVISORY AS CAD MAY BE DEEP ENOUGH
FOR THIS PRECIP TO BE SLEET IF IT MAKES IT.
ON SUNDAY...ALL AREAS BASICALLY EAST OF I-81 WILL BE A SLEET/FZRA
MIX WITH MORE SNOW/SLEET TO THE WEST. DRY SLOT ASSOCIATED WITH UL
JET CUTS ACROSS NORTHEAST PA AND ERN NY DURING THE MIDDAY HOURS...AND
THIS MAY CURTAIL A LOT OF THE PRECIP ANYWAY...ESPECIALLY OVER NEPA
WHERE IT MAY JUST WIND UP AS FZDZ FOR A WHILE.
THE TRANSFER COMPLETES DURING THE AFTERNOON...THE THERMAL COLUMN
COOLS BACK ENOUGH FOR ALL AREAS TO COME AROUND TO SNOW AGAIN BY
EVENING. QUESTION IS...HOW MUCH PUNCH DO WE HAVE LEFT ON THE BACK
SIDE OF THE UPPER LOW...AND WILL WE BE IN THE RIGHT POSITION?
LEANING WITH THE GFS SOLUTION HERE...AGAIN WITH MORE OF THE CUTOFF
LOW TRACK OVER THE FCST AREA VERSUS WEST. SO...KEEPING FAIRLY
HIGH SNOW TOTALS EXTENDING FROM THE FINGER LAKES TO THE MOHAWK
VALLEY AND TUG HILL. THESE AREAS WILL ALSO HAVE LAKE ENHANCEMENT FOR
SNOWFALL GOING INTO SUNDAY NIGHT.
&&
.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/...
SNOW IN THE EVENING WINDS DOWN...EXCEPT IN LAKE EFFECT COUNTRY
WHERE MORE ACCUMULATIONS LIKELY INTO MONDAY AS THE SETUP LOOKS TO
BE VERY UNSTABLE WITH GOOD WNW TRAJECTORIES. WILL ADDRESS THIS MORE
FULLY TOMORROW. NORTHWEST WINDS WILL INCREASE QUITE A BIT BEHIND
THIS SYSTEM ON SUNDAY NIGHT AND MONDAY WITH GUSTS OVER 30 MPH
POTENTIALLY POSING A PROBLEM FOR ICED UP...OR HEAVILY SNOWED
AREAS. QUITER WEATHER AS WE GET INTO TUESDAY...WITH HIGH PRESSURE
BUILDING IN...BUT STILL COLD. LES PLUMES SHOULD WEAKEN AWAY BY
MONDAY NIGHT.
&&
.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
HIGH PRESSURE AT START MOVING EAST INTO NEW ENGLAND. WEAK FAST
MOVING UPPER LEVEL WAVE GOES ACROSS SE CANADA WEDNESDAY. SOME SNOW
SHOWERS IN NY BUT LIGHT ACCUMULATIONS. WEAK HIGH PRESSURE THURSDAY
THEN ANOTHER POTENTIAL STORM FOR FRIDAY TO SATURDAY. PRECIP COMES IN
THURSDAY NIGHT AND REMAINS INTO SATURDAY NIGHT. STILL MUCH
UNCERTAINTY ON SCENARIO FOR THIS STORM...ALTHOUGH MODELS CLOSER THAN
THEY WERE FRIDAY. MORE MODELS HAVE A OHIO VALLEY STORM TRANSFERRING
TO THE COAST. WARM ENOUGH AIR THAT COULD AGAIN BE A MIX.
