If there isn't another jump NW at 12z, I'm writing this off for up here.  That's just the way the snowball's rolled this year for the hinterlands.

 

I would give it until sunday, To many times this winter we have had changes even inside 48 hrs so you really can't totally discount it, Today is a key day on the models to see which direction this moves

Western ridge looked better....trough looked deeper. It's just a little too late. That SPV came south again...it'd be nice if we could get some interaction with that and drop it in to some degree.

Not dead yet.  Pleasantly surprised to see post hr. 66.  0.1 - 0.25" in 6 hour intervals isn't going to cut it in late March though (esp. if it's daytime).

 

Verbatim - Nantucket gets 18-24" while Ray gets a coating on grassy surfaces. :lol:

upton:

 

.LONG TERM /TUESDAY THROUGH FRIDAY/...
MODELS CONTINUE TO SHOW A COASTAL STORM WHICH COULD HAVE
SIGNIFICANT IMPACTS FOR OUR FORECAST AREA TUESDAY INTO WEDNESDAY.
THE ECMWF AND ITS ENSEMBLE MEAN HAVE BEEN CONSISTENT IN BRINGING
THE CENTER OF THE STORM NOT TOO FAR TO THE SE OF THE 40W/70N
BENCHMARK WED MORNING...AND THE GFS OVER THE PAST DAY HAS TRENDED
NORTH TOWARDS THIS SOLUTION. CMC SHOWS A SIMILAR TRACK.

THIS IS A DIFFERENT SCENARIO FROM A COUPLE OF PREVIOUS STORMS THAT
ENDED UP BEING SUPPRESSED TO THE SOUTH BY CONFLUENCE AND STRONG HIGH
PRESSURE BUILDING IN FROM THE NORTH. INSTEAD...IF THIS IS A COMPLETE
MISS...IT WILL PROBABLY HINGE MORE ON THE TIMING AND DEGREE OF
PHASING OF SHORTWAVE ENERGY EMERGING FROM THE PAC NW REGION...SOME
ENERGY DIVING DOWN FROM NW CANADA...AND POSSIBLY SOME ENERGY
BREAKING OFF FROM THE POLAR VORTEX CENTERED EAST OF HUDSON BAY. SUNY
STONY BROOK ENSEMBLE SENSITIVITY ANALYSIS FOR BOTH ECMWF AND GEFS
HAD EARLIER SUGGESTED THAT THE PAC NW ENERGY ARRIVING ONSHORE SUNDAY
NIGHT WOULD HAVE THE GREATEST INFLUENCE ON THE EVENTUAL NORTH-SOUTH
UNCERTAINTY OF THE STORM TRACK. AT LEAST WITH THE GEFS ON THE 12Z
RUN...IT IS NOW FOCUSING MORE ON THE SHORTWAVE ENERGY DIVING DOWN
FROM NW CANADA. IT HAS ALSO SHOWN FOR THE PAST COUPLE OF DAYS A
LARGE DEGREE OF ENSEMBLE SPREAD IN MSLP TO THE N OF EACH OF THE MEAN
TRACKS...IMPLYING THAT THE TRACK WOULD BE AT LEAST A LITTLE FARTHER
NORTH.

WOULD LIKE TO SEE A STRONGER SIGNAL OF SHORTWAVE PHASING AND/OR AN
EARLIER CLOSING OF THE 500MB LOW BEFORE BEING MORE CONVINCED THAT
THIS STORM WILL ACTUALLY END UP CLOSE ENOUGH FOR THE LIKELIHOOD OF
SIGNIFICANT IMPACTS. THE STORM WOULD OTHERWISE BE MORE
PROGRESSIVE...NOTING ALSO A LACK OF DOWNSTREAM BLOCKING. GIVEN
RECENT TRENDS AND ENSEMBLE SENSITIVITY ANALYSIS...WOULD NOT BE
SURPRISED TO SEE A SLIGHT NW TRACK NUDGE OF THE DETERMINISTIC RUNS
FOR THE NEXT CYCLE OR TWO. MODEL CONSENSUS FOR THE STORM TRACK HAS
NOT CHANGED ALL THAT MUCH FROM THE 00Z SUITE...AND WE ARE NOW ONLY
12 HOURS CLOSER TO AN EVENT THAT MAY START 4 DAYS FROM NOW. WILL
THEREFORE KEEP POPS CAPPED AT 50 PERCENT FOR THE EVENT.

SHOULD MSLP FORECASTS PAN OUT...THIS WILL BE POWERFUL LOW WITH
STRONG WINDS AT LEAST FOR THE COASTAL SECTIONS. FORTUNATELY...WE
WOULD BE IN BETWEEN A FULL AND NEW MOON...SO ASTRONOMICAL HIGH TIDE
CYCLES WILL NOT BE AS HIGH AS THEY COULD BE. WITH THE CURRENT
FORECAST TRACK JUST SE OF THE 40W/70N BENCHMARK...THIS WOULD
PROBABLY BE AN ALL-SNOW EVENT WITH A CONTINUATION OF BELOW-NORMAL
TEMPERATURES.

HIGH PRESSURE BUILDS IN BEHIND THE STORM WEDS NIGHT THROUGH
THURSDAY. TEMPS START TO REBOUND CLOSER TO NORMAL WITH RISING
HEIGHTS. LOW PRESSURE MOVING INVOF THE EASTERN GREAT LAKES AND ST.
LAWRENCE RIVER VALLEY THEN BRINGS A CHANCE OF RAIN SHOWERS FRIDAY.
A SW FLOW AHEAD OF THIS SYSTEM WILL HELP PUSH TEMPS ABOVE NORMAL.
