With blocking that severe the ceiling for this December is very high, as in 20+ inches of snow for the month in most of SNE. That is a lot, but it only takes one storm to reach those amounts with this severe North Atlantic blocking pattern. Instead of getting 12 hour storms with a positive NAO in this pattern due to the blocked flow the low isn’t going anywhere, so we would get 24 hour storms instead, possibly longer. With the warm ssts offshore I’m thinking a March 2018 redux, where the NW areas get clobbered with the first storm or 2. Then mid to late month when the cold air is more established (there are signs of a polar vortex displacement event on the models, despite no SSW), the clash between the northern airmass and the mild early season Atlantic Ocean SSTs leads to any area of low pressure forced to redevelop offshore due to the blocking to undergo rapid cyclogenesis as it comes up the coast, deepening into the 960s. On top of this, we have the increased water vapor in the atmosphere due to the volcanic activity last year, this increase in water vapor will lead to truly obscene QPF totals.

I've gotta raise the bullshit flag on that statement.  I suspect that November snow has always been rare, so much so that no trend can be discerned.

Hard to say…rarer if you start 40 or 50 years ago as your baseline. There were a bunch of snowy Novembers in the 1980s…ironic considering the winters were mostly shit for snow. :lol:
 

But really prior to the 1970s isn’t impressive. 
 

2” or more Novembers in BOS by decade:

2010s: 1

2000s: 2

1990s: 2

1980s: 5

1970s: 3

1960s: 1

1950s: 1

1940s: 2

1930s: 3

1920s: 1

1910s: 1

1900s: 0

Will . That Ensembles look. Just put up a patience Grasshoppers alert. The term used in Jan 11 when Scooter was crying about sledding on mud.

December 2010 was uber painful here with a big snowstorm in Boston on the 18th IIRC and a Mt Rushmore bust locally on Boxing Day.  But the same patience grasshopper advice would have applied because Jan and Feb were wonderful.

Edit- seemed like the big snow was the 20th in SEMA not Bos

Retro storm that crushed the Cape. They had over a foot in some spots there. It was an otherwise frustrating winter on the Cape but they got smoked in that one. 
 

It did snow like 2-3” though around BOS. We even had a couple inches back in ORH which gave us a White Christmas.

I was just in an unlucky spot for the Boxing day storm, overall it wasn't a bad storm. I'd take my chances with another one like it.

It Crushed northern NJ and NYC.  A lot of wind here with A Blizzard warning and 10-12 inches of arctic sand.  A disappointment compared to what was forecast though.  But then after New Years in Jan 11 it went gang busters.

Kind of dumb comparing a place that’s inland  to a coastal place where a few things need to come together lol. It’s a fringe month. Lots of things can happen in a short time span.

Hopefully things pan out. We’ll see…need more than just a “good look”. I’m still waiting for the solid snows from the good look patterns from 2 winters ago. 

Hey even in meh winters we had some stretches. Feb 2021 was decent. Early Jan through late Feb 2022 was good too.

I’m pretty sure that was the last white Christmas we had here locally. So it’s been 12 years. I’d say we are due here, even with not so great white Christmas averages

That is true. Sometimes it’s more about getting pieces to align as opposed to the pattern itself. I think this winter is going to be even more complex than the last few. The global pattern is quite chaotic. I think it’s going to be difficult to put much stock into D7-10+ progs…even if there is model agreement.
