Yeah probably...but its reallythe one after today that is the biggest problem. It tracks over the northern lakes and into NNE prior to the 2/3 wave.

 

Yeah, Thats no good as well, There are just to many in the flow, In a good year, Some of these would have been decent clippers

They are getting/have gotten more than an inch I think.  They had a nice clipper snow.

 

I didn't read HPC reasoning....but I will when I get off a conf call.  It is not that I dont' trust us on here, but HPC is good and I read them all the time.  We'll see...hoppin on a call.

And anyway....Dover snow more of less proves the point. Remember when srefs and nam had that for us a few days ago?

Yeah...a lot of times these patterns will give nice advisory or even low end warning clipper/redevelopers....as Ryan mentioned earlier, we've had some lousy luck. The pattern itself is progressive, but it doesn't mean that these progressive patterns always favor garbage systems. They just don't favor KUs. We've had some horribly spaced shortwaves, which are not a symptom of the long wave pattern, they are chaos amongst it. They are not predictable beyond a few days out.

Oh, well I don't see it snowing less than 15" in BOS, and probably not 20". If we make it to March with under 15" then I'll start to get interested. Its Feb 1st.

 

...and we have 8.8" lol

 

I know (and hope) the current pattern will probably change and a single bomb or even a couple nickle-dimers in late February or March can change a season, but we've been hearing the "climo" appeals for snow for a long, long time...

I'm not saying every threat is hosed, it's just a very fast flow with zero time for amplification unless the location is just right. I don't have confidence in any threat for now until either the s/w is further north, or we get the flow to buckle.

 

With the way the flow is, we'd want any amplification/phasing to occur over freakin' AR.  LOL.

Here is the HPC reasoning at 4:15am

 

 

A MORE INTERESTING DAY IS IN STORE ON DAY 3...WHEN THE TWOSEPARATE SYSTEMS APPEAR TO MERGE OR AT LEAST ATTEMPT TO MERGE INTOA DEVELOPING NEGATIVELY TILTED TROUGH ALONG THE EAST COAST. THEUKMET AND NAM PCPN WERE WETTER ALONG THE NORTHEAST/NEW ENGLANDCOAST COMPARED TO THE CONSENSUS OF OTHER MODELS. THE UKMET INPARTICULAR WAS THE DEEPER AND FARTHEST W WITH THE LOW COMPARED TOTHE OTHER MODELS...THOUGH NOT BY MUCH AT 00Z AS THE SPREADDIMINISHES A BIT OVER PRIOR RUNS. THE 00Z ECMWF TRENDED CLOSER TOTHE GFS...AS BOTH OF THESE MODELS AVERAGE BTWN A TENTH UP TO AQUARTER INCH OF LIQUID PCPN ALONG THE NE COAST...WITH THE HIGHESTAMOUNTS OFFSHORE. HPC FOLLOWED SUIT WITH A LOW-MOD PROBABILITY OFGREATER THAN 4 INCHES...WITH THE HIGHEST (MODERATE) PROBS CONFINEDCLOSER TO THE COAST FROM RI TO ERN CT/MA. PROBABILITIES OF GREATERTHAN 8 INCHES...ALBEIT LOW (10%)...WERE NOTED OVER THIS SAMEAREA...GIVEN THE POSSIBILITY OF MORE RAPID COASTAL CYCLOGENESISAND (THUS) A SFC LOW TRACK CLOSER TO THE COAST. AS IT IS...MANY OFTHE 00Z MODELS INDICATED AN AVERAGE DEEPENING OF 12-15MB IN 12 HRS(FROM 12Z SUN TO 00Z MON) AS THE SFC LOW TAKES SHAPE OFF THE MIDATLC COAST AND TRACKS NE.

There's many years that had that or less on this date. Its bad, but lets not pretend this is uncharted territory.

 

I'll give you a list:

 

1899-1900

1900-1901

1925-1926

1927-1928

1931-1932

1936-1937

1941-1942

1943-1944

1957-1958

1968-1969

1972-1973

1974-1975

1979-1980

1985-1986

1991-1992

1994-1995

2006-2007

2011-2012

 

 

This was just using 8.8" as the cutoff...probably another half dozen years had between 8.8 and 10" at this point. Again, I'm not disagreeing its been a pretty terrible winter thus far for BOS...its just that it happens every now and then. Not unprecedented by any stretch. If it keeps up and they put up a foot for the whole season, then that is some histroic back to back futility, but we have a long ways to go.

None of your glorious models gave Delaware or S Jersey 6 inches of snow this morning. Put the f'ing models away and forecast on pattern and instincts

good idea.

 

the pattern is very progressive and supports offshore development that clips E areas with light snows. most should be expecting very light snow showers or flurries.

yeah, anyone calling for more than a 1-2" has lost it at this point, things could change of course but not likely, hope we are all wrong.

Depends on your definition fo snowy...BOS median snowfall is a bit over 40" per season...mean is about 44". That's pretty snowy for a big city. But if your definition of just a typical snowy place is Stow, VT or Rangely, ME, then its like Florida when it comes to snowfall in comparison to that.

Uh... I never said 8.8" is unchartered territory... 

 

I'm not sure what the debate is.

You've listed winters that, like this one, were mostly terrible.

 

Of those with 8.8" as the cutoff, almost all end up < 25", and 8 of 18 ended up < 20":

1900-1901

1936-1937

1972-1973

1979-1980

1985-1986

1994-1995

2006-2007

2011-2012

 

And with the exception of 1899-1901, none of those 8.8"-by-Feb-1st winters were back to back.

 

My only point was that back to back ratters are rare, and a back to back winter < 20" total (which you can't deny is possible this year) would be unprecedented.

 

Sure anything is possible. We may even get a Feb 1969, but I'm not holding my breath lol

i would welcome a mix at this point - would actually mean this thing is coming remotely close to the area. 

This whole system screams, MEH, to me.  Too many cooks in the kitchen to get anything remotely well defined.

I'd back off BOXs forecast by 1/2 based on what I see.  Best chance for accumulating snows will be in SE MA and CC.  General 1-3 with a T-1" for western areas of the CWA.
