The episode as NWS BGM wrote it up.
Low pressure formed off the North Carolina coast and tracked slowly northeast to off the Delmarva Peninsula by Wednesday morning the 24th. The storm then tracked out to sea. Light snow, mixed with rain, spread into northeast Pennsylvania, mainly east of Interstate 81, during the daylight hours of Tuesday the 23rd. The snow became heavier and steadier Tuesday night and tapered off Wednesday morning the 24th. The heaviest snow fell in Pike county, PA where between 5 and 17 inches fell. The heaviest snow was found over the higher terrain.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BINGHAMTON NY
357 PM EST TUE FEB 23 2010
.SYNOPSIS...
LOW PRESSURE WILL TRACK NORTH ALONG THE EAST COAST TONIGHT...
BRINGING SNOW TO NORTHEAST PENNSYLVANIA AND CENTRAL NEW YORK. THE
SNOW WILL MIX WITH RAIN EARLY TONIGHT OVER LOWER ELEVATIONS.
SEVERAL INCHES OF SNOW WILL ACCUMULATE... ESPECIALLY EAST OF
INTERSTATE 81. AN EVEN MORE POWERFUL STORM WILL AFFECT THE REGION
FOR THURSDAY NIGHT INTO FRIDAY WITH A CHANCE FOR MORE WIDESPREAD
SNOW.
&&
.NEAR TERM /UNTIL 11 PM THIS EVENING/...
WATER VAPOR IMAGERY SHOWS A SIGNIFICANT WAVE MOVING EAST FROM THE
OHIO VALLEY TOWARD THE CENTRAL APPALACHIAN MOUNTAINS. SURFACE LOW
DEVELOPING EAST OF THE MID-ATLANTIC COAST IS FORECAST TO MOVE
NORTH TOWARD THE SOUTHERN NEW ENGLAND COAST TONIGHT. A BAND OF
MODERATE PRECIPITATION IS TRAINING NORTH ACROSS EASTERN PA TOWARD
THE CATSKILLS. PRECIPITATION TYPE LATE THIS AFTERNOON IS A MIX OF
RAIN AND SNOW WITH TEMPERATURES IN THE LOWER TO MID 30S. EXPECT
PRECIPITATION TO CONTINUE TO STREAM NORTHWARD DURING THE NEXT
SEVERAL HOURS AS THE OHIO VALLEY SHORT WAVE TRACKS EAST... THEN
NORTHEAST AND BEGINS TO TAKE ON A NEGATIVE TILT. RAIN WILL
CONTINUE TO MIX WITH THE SNOW AT LOWER ELEVATIONS INTO THIS
EVENING... BUT SLIGHT COOLING DUE TO THE SETTING OF THE SUN AND
MELTING SHOULD CHANGE MOST PLACES OVER TO SNOW EARLY THIS EVENING.
MODEL FORECAST SOUHDINGS ARE NOT SHOWING ANY WARM LAYER ALOFT...
SO PRECIPITATION TYPE WILL BE DICTATED BY SURFACE TEMPERATURES AND
THE DEPTH OF THE SURFACE-BASED WARM LAYER. THE BACK EDGE OF THE
PRECIPITATION WILL LIKELY BACK SLIGHTLY WESTWARD THIS EVENING AS
THE WAVE BECOMES NEGATIVELY TILTED AS IT MOVES NORTHWARD... PROBABLY
REACHING AS FAR WEST AS CORNING TO AUBURN BY MID-EVENING.
MEANWHILE BANDS OF HEAVY SNOW WILL TRACK NORTH FROM THE EASTERN
POCONOS TO THE CATSKILLS.
&&
.SHORT TERM /11 PM THIS EVENING THROUGH FRIDAY/...
HEAVIEST PRECIPITATION ASSOCIATED WITH THIS SYSTEM WILL EFFECT THE
AREA LATER TONIGHT AS STRONGEST UPPER LEVEL PV ADVECTION COMBINES
WITH SIGNFICANT MID-LEVEL FRONTOGENETICAL FORCING OVER THE EASTERN
COUNTIES. A NOSE OF REDUCED LAPSE RATES AND WEAKLY NEGATIVE
SATURATION EPV IS ALSO FORECAST BY THE NAM FROM NJ NORTH TO THE
SOUTHERN CATSKILLS LATER TONIGHT... EXTENDING NORTHWARD INTO THE
FRONTOGENETICAL DIRECT CIRCULATION. THE RESULT WILL BE BANDS OF
HEAVY SNOW FOR THE WESTERN CATSKILLS WITH SEVERAL INCHES OF
ACCUMULATION. HAVE GONE WITH A WARNING FOR THE COUNTIES LIKELY TO
BE EFFECTED BY THESE HEAVIER BANDS... WITH AN ONE COUNTY WIDE
ADVISORY JUST TO THE WEST FOR 2 TO 6 INCHES OF SNOW. BEST FORCING
LIFTS NORTHEAST AWAY FROM NE PA WEDNESDAY MORNING... AND NORTHEAST
OF THE CATSKILLS WEDNESDAY AFTERNOON... WITH SNOW COMING
TEMPORARILY TO AN END.
THE NEXT STORM BEGINS TO IMPINGE ON THE REGION WED NIGHT...LIKELY
LASTING INTO FRI. ALTHOUGH SOME SUBTLE POSITION DIFFERENCES ARE
EVIDENT AMONGST OUR SUITE OF MODELS...THEY ALL HAVE THE SAME BASIC
IDEA. THE MID-LEVEL TROUGH RE-LOADS ACROSS THE EASTERN U.S. LATE
WED...WITH THE 500-700 MB CENTERS DEEPENING RAPIDLY ACROSS LONG
ISLAND/CT BY THU. ADDITIONALLY...ITS NORTHWARD PROGRESSION IS
EFFECTIVELY BLOCKED BY THIS TIME...AS A LARGE RIDGE BUILDS IN
ACROSS THE CANADIAN MARITIMES. THIS ACTS TO HOOK THE SURFACE WAVE
FROM OFF THE MID- ATLANTIC COAST...BACK IN TOWARDS WESTERN NEW
ENGLAND...AND POSSIBLY EVEN THE HUDSON VALLEY.
QVEC/FGEN/EPV/ISENTROPIC SIGNATURES ALL POINT TO A PERIOD OF HEAVY
SNOWFALL IN OUR FORECAST AREA...PROBABLY STARTING TOWARDS DAYBREAK
THU...AND CONTINUING INTO THU EVE. ALTHOUGH THE OVERALL INTENSITY
MAY START TO WANE LATER THU NIGHT AND FRI...LIGHTER WRAP-AROUND
SNOWS ARE STILL LIKELY...WITH ONLY A VERY GRADUAL SYSTEM
DEPARTURE...AS ALLUDED TO ABOVE.
ANOTHER ISSUE LATER THU INTO FRI COULD BE THE WINDS...AS THE
PRESSURE GRADIENT TIGHTENS SIGNIFICANTLY THIS PERIOD...PROBABLY
LEADING TO PLENTY OF BLOWING/DRIFTING. BOTTOM LINE...WINTER STORM
WATCHES WILL BE POSTED FOR ALL OF CENTRAL NY/NORTHEAST PA...FROM
06Z THU...TO 00Z SAT.
UNDERCUT MOS TEMPERATURES BY SEVERAL DEGREES THU AND FRI...ONCE
STEADIER/HEAVIER SNOW SETS IN.
&&
.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
FRIDAY NIGHT THROUGH SUNDAY NIGHT, VERTICALLY STACKED LOW OVER NEW
ENGLAND REMAINS NEARLY STATIONARY THROUGH PERIOD AS UPPER LEVEL
RIDGE REMAINS OVER THE CANADIAN MARITIMES. FRIDAY NIGHT WILL GO
WITH LIKELY POPS FOR NYS IN WRAP AROUND MOISTURE WITH HIGH CHC POPS
FAR SE FA. SATURDAY THROUGH SUNDAY NIGHT, WILL CONTINUE WITH CHC
POPS FOR SNOW SHOWERS AS WRAP AROUND CONTINUES IN NORTHWEST FLOW.
WITH T85 AROUND -6/-8C, ANY LAKE EFFECT CONTRIBUTION WOULD BE SMALL.
MONDAY THROUGH TUESDAY, SYSTEM FINALLY MOVES OFF THE SOUTHERN NEW
ENGLAND COAST AND OUT TO SEA. PERIOD SHOULD BE FAIRLY DRY WITH TEMPS
SLIGHTLY ABOVE NORMAL.
&&
.AVIATION /21Z TUESDAY THROUGH SUNDAY/...
RESTRICTIONS WILL BE PREVALENT THROUGH 18Z WED...AS A PERIOD OF
STEADIER SNOWFALL LEADS TO WIDESPREAD IFR...PARTICULARLY FROM THE
OVERNIGHT HOURS INTO EARLY WED.
THE LOWEST CONDITIONS WILL LIKELY BE EXPERIENCED AT KBGM/KRME...AND
POSSIBLY KAVP...WHERE SOME LIFR IS POSSIBLE.
GENERALLY LIGHT SURFACE WINDS TONIGHT...WILL BECOME WEST TO
NORTHWEST ON WED...AT 5-10 KT.
OUTLOOK...
WED NGT THRU FRI...WIDESPREAD MVFR/IFR IN SNOW.
FRI NGT THRU SUN...OCCASIONAL MVFR/IFR IN SNOW SHOWERS.
