What happened

The episode as NWS PBZ wrote it up.

A complex storm system moved northeast across the region the morning of November 26th into the morning of the 27th. A period of snow accumulated 1 to 4 inches across much of eastern Ohio, western Pennsylvania, northern West Virginia, and Garrett county Maryland before mixing with and changing to rain. The precipitation remained all snow in a band from Forest county Pennsylvania to Columbiana county Ohio where a general 6 to 10 inches of snow fell. In Garrett county Maryland low level cold air was trapped allowing for freezing rain to accumulate from a quarter to one half inch across the eastern half of the county.

What forecasters said that day

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Pittsburgh, PA wrote its last area forecast discussion before the first event at Nov 26, 7:47 AM EST, 2 hours 13 minutes earlier.

Area forecast discussion, Nov 26, 7:47 AM EST, 2 hours 13 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PITTSBURGH PA
747 AM EST TUE NOV 26 2013

.SYNOPSIS...
EAST COAST BOUND LOW PRESSURE WILL SPREAD A WINTRY MIX OF
PRECIPITATION OVER THE REGION TODAY. THAT PRECIPITATION WILL
CHANGE TO ALL SNOW TONIGHT.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
CONFLUENT FLOW AS WELL AS A TIGHT BAND OF FRONTOGENESIS THAT WAS
WELL SAMPLED ON THE NAM BETWEEN 500 AND 300 MB...WHICH IS ROUGHLY
COINCIDENT WITH THE DENDRITIC GROWTH ZONE HAS RESULTED IN A BAND
OF FAIRLY STEADY SNOWFALL THAT HAS PUSHED SLOWLY FROM SOUTH TO
NORTH ALREADY THIS MORNING FROM ZANESVILLE TO WHEELING TO
PITTSBURGH TO LATROBE. AMOUNTS TO THIS POINT OUT OF THIS BAND HAVE
BEEN ROUGHLY 1.5 TO 3.5 INCHES...HOWEVER RECENT RADAR TRENDS AS
WELL AS MODEL TRENDS SUGGEST THIS BAND IS LIKELY TO STRENGTHEN AS
A WARMER PUSH OF AIR ALOFT IS SET TO ADVANCE NORTHWARD THROUGH THE
MORNING HOURS AS IT SLOWLY MEANDERS NORTHWARD. QPF AND SNOW
AMOUNTS WERE BUMPED UPWARD SUBSTANTIALLY IN THIS BAND THROUGH THE
MORNING HOURS...WITH IMPRESSIVE 20:1 RATIOS NOTED AT THE NWS
OFFICE THIS MORNING. WHILE THESE RATIOS ARE UNLIKELY TO LAST AFTER
SUN UP...IT STILL SEEMS REASONABLE TO ANTICIPATE THAT AT LEAST
10:1 WOULD PERSIST BEYOND SUNRISE.

THE REST OF THE FORECAST STILL LOOKS GOOD FOR TRANSITIONS TO
RAIN/SLEET/FREEZING RAIN IN PORTIONS OF THE AREA. THE DETAILS OF
THE RATIONALE OF THAT PORTION OF THE FORECAST ARE CONTAINED BELOW.
FRIES

PREVIOUS...
A SHORTWAVE MOVING ACROSS OHIO INTO NORTHWESTERN PENNSYLVANIA HAS
ALLOWED FOR A PRECURSOR ROUND OF SNOW IN ADVANCE OF THE MAJOR SYSTEM
ARRIVING THIS MORNING. AN INCH OF SNOW HAS FALLEN AT OUR
OFFICE...AND AREA WEBCAMS SHOW SOME LIGHT ACCUMULATIONS GENERALLY ON
GRASSY SURFACES...ALTHOUGH AREA ROADWAYS STILL APPEAR TO BE MOSTLY
WET. THIS LIGHT SNOW SHOULD CONTINUE THROUGH SUNRISE.

NORTHERN STREAM AND SOUTHERN STREAM SYSTEMS ARE BOTH STARTING THEIR
TREK TO THE EAST...WITH THEIR INTERACTION ABOUT TO AFFECT THE ENTIRE
EAST COAST. SO FAR THE PRECIPITATION SHIELD FROM THE SOUTHERN SYSTEM
IS CONTAINED TO SOUTHERN KENTUCKY AND VIRGINIA...WITH PRECIPITATION
MOVING TO THE NORTHEAST. TRICKIEST PORTION OF THE FORECAST REMAINS
WHAT WILL HAPPEN WITH LOW LEVEL TEMPERATURE PROFILES. ENOUGH WARM
AIR IS EXPECTED TO MOVE IN ALOFT THAT A MIX OF SNOW AND FREEZING
RAIN IS POSSIBLE GENERALLY SOUTH AND EAST OF A LINE FROM ZANESVILLE
TO PITTSBURGH TO DUBOIS DURING THE DAYTIME. IN ADDITION...SURFACE
TEMPERATURES WILL BE CRITICAL...AS PRECIP MAY ACTUALLY FALL AS RAIN
FOR A SEVERAL HOUR PERIOD. LATEST RUNS OF THE RAP STILL SHOW ABOVE
FREEZING TEMPERATURES REACHING ALL THE WAY INTO INDIANA COUNTY NEAR
THE SURFACE. THE RAP CAME IN AS THE WARMEST MODEL FOR SURFACE
TEMPERATURES...BUT IT ALSO USUALLY HANDLES THESE SITUATIONS WELL.
THE HIGHER ELEVATIONS IN THE RIDGES WILL LIKELY HAVE A WINTRY MIX
THROUGH MUCH OF THIS TIME PERIOD WITH AN EXTENDED PERIOD OF FREEZING
RAIN POSSIBLE. NORTH AND WEST OF THE ZZV/PIT/DUJ LINE...SOME SLEET
MAY MIX IN BY THE AFTERNOON...BUT SNOW IS EXPECTED TO BE THE
DOMINANT PRECIPITATION TYPE.

BY EVENING THE TWO SYSTEMS ARE EXPECTED TO BE IN ENOUGH PROXIMITY TO
EACH OTHER TO DEVELOP A COUPLED JET...AND CONSEQUENTLY SHOULD BE THE
TIME PERIOD WHEN THE HIGHEST PRECIPITATION RATES OCCUR. IN THE
RIDGES...FREEZING RAIN WILL CONTINUE THROUGH THE EVENING.
TEMPERATURES WILL LIKELY STILL BE WARM ENOUGH SOUTH AND EAST OF
PITTSBURGH OUTSIDE OF THE HIGHEST ELEVATIONS TO PERSIST WITH RAIN
FOR A FEW HOURS. HOWEVER...WITH ALL SNOW FALLING TO THE WEST OF
PITTSBURGH...SNOW RATES COULD BE QUITE IMPRESSIVE DURING THE EVENING
HOURS FROM ZANESVILLE TO NEW CASTLE AND FRANKLIN. AFTER MIDNIGHT
NEARLY ALL LOCATIONS WILL CHANGEOVER TO SNOW...WITH RATES BEGINNING
TO DIMINISH SLIGHTLY. IF THE WARM LAYER ALOFT PERSISTS...WHICH
LATEST MODELS RUNS HAVE BEEN INDICATING IS POSSIBLE...FREEZING
RAIN MAY HOLD ON FOR A FEW MORE HOURS IN THE RIDGES.

ALTHOUGH ALL LOCATIONS WILL CONTINUE TO RECEIVE SNOW WEDNESDAY
MORNING...THE WIDESPREAD PRECIPITATION SHIELD WILL BE MOVING OFF TO
THE EAST. ALTHOUGH WINDS WILL INITIALLY BE OUT OF THE
NORTH-NORTHWEST...LESS FAVORABLE FOR UPSLOPE/LAKE EFFECT...WINDS
WILL BACK TO THE NORTHWEST BY THE AFTERNOON AND ALLOW THE LAKE
EFFECT MACHINE TO START UP.

ALL IN ALL...ONLY MINOR CHANGES WERE MADE TO THE FORECAST THROUGH
THIS TIME PERIOD. THE AXIS OF HEAVIEST SNOWFALL WAS PUSHED SLIGHTLY
FARTHER TO THE WEST TO ALIGN WITH DEFORMATION ZONE AND THE CHANCES
FOR FREEZING RAIN WERE HELD ONTO LONGER TONIGHT IN THE RIDGES...BUT
OTHERWISE THE INHERITED FORECAST WAS IN GOOD SHAPE. NO CHANGES WERE
NEEDED TO ANY OF THE ADVISORIES OR WARNINGS.

&&

.SHORT TERM /WEDNESDAY NIGHT/...
UPSLOPE AND LAKE EFFECT SNOW WILL CONTINUE WEDNESDAY NIGHT. MODELS
ARE SUGGESTING THAT A DOUBLE LAKE CONNECTION BETWEEN HURON-ERIE IS
POSSIBLE...WHICH COULD RESULT IN SOME LOCALLY HIGHER TOTALS IF A
SINGLE DOMINANT BAND DEVELOP SIMILAR TO WHAT HAPPENED THIS
PREVIOUS SATURDAY. THE RETURN OF WEST-NORTHWESTERLY FLOW WILL
BRING LOWS DOWN INTO THE UPPER TEENS.

&&

.LONG TERM /THURSDAY THROUGH MONDAY/...
DRYING TREND CAN BE ANTICIPATED INTO THE WEEKEND AS THE UPR FLOW
FLATTENS...ALTHOUGH SUB AVG TEMPS WL CONT UNTIL WARM ADVCTN
INTENSIFIES WITH THE ADVN OF LOW PRES EARLY NXT WEEK. PASSAGE OF
THAT TROF IS GFS AND ECMWF FORECAST TO SPREAD RAIN...OR SNOW OVR
THE UPPER OH VALLEY REGION ON MONDAY AND TUESDAY. CHC POPS WERE
THUS INCLUDED FOR THAT TIME FRAME...BUT RESOLUTION OF PCPN TYPE WL
HAVE TO WAIT UNTIL THE SITUATION FURTHER MATURES.

&&

.AVIATION /13Z TUESDAY THROUGH SATURDAY/...
DETERIORATION TO GENL IFR WL CONT TDA AS LGT SN...THEN A MIXTURE
OF WINTRY PCPN SPREADS OVR THE REGION WITH LOW PRES EMERGING FM
THE GULF COAST AREA. IFR CONDITIONS WL THEN PREVAIL THROUGH TNGT
WITH COLD ADVCNT CHANGING PCPN TO ALL SNOW.

.OUTLOOK.../WEDNESDAY THROUGH SATURDAY/...
WDSPRD RSTRNS WL CONT THRU WED NGT AS COLD ADVCTN INTENSIFIES IN
THE WAKE OF EXITING LOW PRES. VFR IS EXPD TO RTN LTR THU WITH BLDG
HIGH PRES AND PERSIST FOR THE RMNDR OF THE WEEK.
