I am getting frustrated that there is no clear forecast yet. Nws Binghamton told me that they are waiting for another model to come in, and then it would be as clear as mud.

Theyre waiting on the Euro then. If it holds it is fairly clear the GFS is the outlier, and the NAM is pulling a Richard Seymore Hoffman.

Latest model discussion from WPC:

"...EASTERN U.S. CYCLONE AND WINTER STORM...

PREFERENCE: 00Z ECMWF WITH SFC LOW TRACK ADJUSTED 40 MILES
SOUTH/EAST

DESPITE BOTH NORTHERN AND SOUTHERN STREAM SHORTWAVES HAVING
ENTERED THE NORTH AMERICAN UPPER AIR NETWORK...SOME SIGNIFICANT
MODEL DIFFERENCES REMAIN. WHAT WE DO KNOW WITH CONFIDENCE IS THAT
THIS STORM WILL PRODUCE VERY DISRUPTIVE ACCUMULATIONS OF ICE AND
SNOW OVER A BROAD SWATH AFFECTING THE SOUTHERN U.S. AND THE EAST
COAST STATES. CONCEPTUALLY THE MODELS INDICATE SIMILAR IDEAS TO
ONE ANOTHER...WITH SURFACE LOW DEVELOPMENT STARTING ALONG THE
CENTRAL GULF COAST AROUND 12/12Z AND THE CYCLONE THEN DEEPENING AS
IT TRACKS ACROSS THE FAR SOUTHEAST STATES TOWARD THE OUTER BANKS
IN NORTH CAROLINA AND THEN UP THE EAST COAST.

THE GFS HAD BEEN ONE OF THE WEAKER SOLUTIONS ESPECIALLY WHEN
MEASURED BY THE SURFACE LOW DEPTH AND THE LATE ONSET OF A CLOSED
CIRCULATION AT 500 MB. THE GFS HAS TRENDED STRONGER AT THE
SURFACE...BUT IS STILL SLOW TO CLOSE OFF A LOW AT 500 MB...AND IS
CORRESPONDINGLY FASTER IN ITS FORWARD SPEED. THE ECMWF HAS STRONG
SUPPORT FROM THE 00Z ECMWF ENSEMBLE MEAN AND THE 00Z UKMET RUN
OCCASIONALLY PHASED WITH THE ECMWF...ESPECIALLY ALONG THE MID
ATLANTIC COAST. STILL...IT IS DIFFICULT TO MOVE OUR PREFERENCE
ENTIRELY TOWARD THE ECMWF...DESPITE ITS RELATIVE CONSISTENCY...AS
THERE IS NO PHYSICAL REASON TO EXPECT THAT THE SURFACE CYCLONE
WILL DEFINITELY SPIN UP AS EARLY AND AS SYMMETRICALLY AS IT DOES
IN THE ECMWF SOLUTION. MANY OTHER SOLUTIONS SUCH AS THE
NAM/SREF/GFS/UKMET HAVE INDICATED A MORE ELONGATED LOW EARLY IN
THE PROCESS...STRETCHED OUT ALONG THE PRE-EXISTING FRONTAL ZONE IN
THE SOUTHERN STATES.

ONE WAY TO RESOLVE THESE DIFFERENCES IS TO TAKE THE CHARACTER AND
INTENSITY OF THE ECMWF SOLUTION AND SHIFT IT JUST SLIGHTLY SOUTH
AND EAST TOWARD MORE OF A CONSENSUS TRACK.

THE NAM HAS FALLEN NEAR CONSENSUS ON OCCASION...BUT THE 12Z RUN
DID NOT. IT IS THE FLATTEST MODEL WITH THE SOUTHERN STREAM
SHORTWAVE THAT SPURS THIS DEVELOPMENT OVER THE SOUTHEAST...WHICH
YIELDS A FAST AND WEAK SYSTEM OVERALL. IT IS NOT RECOMMENDED TO
PUT MUCH IF ANY WEIGHT ON THE NAM AFTER DAY 1."

 

True dat!
