12z GEM is likely the high end of solutions for Monday/Tuesday in terms of how wrapped up this can get...

I am favoring something sub 990 at our latitude given guidance consensus showing this being moisture rich off the SE coast in mid November. Expecting moisture fluxes to play a more important role in deepening this than our garden variety Nor Easter...

You have to wonder if most areas will roll into 2020 without a solid snowstorm. 

That happens many seasons in SNE...what’s your point?
 

Many times it takes until After the first of the year to get anything significant in SNE.  Just the way it goes some years. That’s why March is a winter month and features more snow than both November and December.

Some of these fringe guidance types are trying now to shave 850 mb temps more, too ... now that the models have more unilaterally focused on the lead wave as we were discussing yesterday.  At that time I was speculating that if the 2nd wave were to become the focus, that one appeared to have better chances for marginal/flip to parachutes... But it's interesting that the lead focus is starting to "maybe" inch downward in the profile -

Not saying that means blue bomb in the interior, per se, but... that GGEM solution you reference does not unzip a pocket of -1 to 0 C at 850 mb pretty much collocated with the lower Greens/Whites and western Mass elevations as the low maxes by Cape Cod.   Plus, these make-up-artist QPF products having the IP contamination on the NW edge... I'm not will consign this thing to just wet west of 495 and N of Kevin ... How much remains to be seen.  I could see that continue to modulate fractions and end up more snow in there...Or, it gets windy and rainy and then as the wind gets light in latter innings ... there's this light slush flakes in the street lamps inconsequentially ... Welcome to the game of marginality -

What makes you think SNE isnt going to see any snow for the rest of the year?

He was being sarcastic...meaning that isn’t that bold of a prediction given there’s 6 weeks left to 2019, and each day/week that goes by, it gets more conducive for SNE to see snow.

I don’t think we get shut out from now,  until The new year either.  Something should pop...even just a couple inches is Not that hard as we go into the end of November, and into December.

Not high on people's priority list, I'm sure, but man ... it's 51 here, and after a couple of days where mornings were near 15 and afternoons were in the low to mid 30s, this feels like one of those "fake" balm gems you get in March where people think it's 70!

Nice out.  Doesn't happen without appreciation from me ... even though there's homage given to the coastal early next week and how it even looks interestingly like an unusual ice potential. 

Someone was mentioning the ice storm of the 1920's in November a while back ...that was an unusual coastal storm set up too - hm.  Wonder if there could be any similarity.  I tell you, if that high pressure over eastern Ontario happens to slow a little bit, you get that much more BL resistance and cold loading in the llvs... heh

Boy ..I'll tell ya. It's too bad the NAM were not a more dependable guidance source beyond ... 10 minutes, because this is a truly nasty extrapolation for N-W of HFD-PVD-BOS:

Look at the lower left series of numbers... for Philadelphia.  Down there, in the mid-Atlantic, and the lowest T1 temperature is 34 F with winds 20 kts out of the NE.  That's translating up the coastal plain into SNE where it's probably 30 to 32 and ice.  

The other thing ... unrelated to that, is the surf?  This thing is so so at mid levels, but the models are really maximizing the mechanics of the negative tilting and helping to core this sucker down pretty deep relative to those 500 mb typology.  I mean into the 980s mb isn't too shabby, and with a big high retreating, we end up with an impressive gradient that is approaching from the S. That means it's long shore fetch and probably there are big swells associated.   What's the tide chart like.  I know there's a spring tide scheduled the week of T-giggedy... But that looks like splash over potential either way.  

Hey man, for storm enthusiasts, it's all we got, but it's got some potential to be a multi-facet moderate impact Nor'easter.  We could end up with noodles mixed with zrain falling into 31.8 F interior surface layer.  That'd be neat.

I see some sled tracks on the Rangely Lakes Snowmobile Club webcams. That's got to be pretty early. Looks like 6" or so OTG.

Oh ya...the locals get out when the ground gets covered.   Way up in N. Aroostook County they got about a foot the other day, and quite a few locals busted out the sleds.  Let’s keep it coming....

I don't think the Euro got that memo about the week of Thanksgiving -

well...maybe it's not terrible at mid latitudes.  But the flow seems kinda flat. 

It looks ok IMHO...not as good as last night's run or the ensembles, but you can see the -NAO building and it looks like EPO ridge is in the process of reloading. Not gangbusters or anything...agreed on that...but probably enough to keep us bothering to watch guidance for interesting threats...esp for interior this time of year.

I'll add that the EPS just coming out looks better than the OP run out at the D10 range....

Does doesn't it ... 

I'll also add ( for how little it's worth ...) every GEFs member has some form or another of an eastern amplitude/coastal storm on the 12z cycle, D's 8-9-10.  I find that interesting... The operational version just happens to be one of the farthest east and more blase solutions -

Yeah... fwiw - the Euro's quasi zonal vibe doesn't really jive too well with the cross-guidance tele/ensemble mean. 

Not that the GEF's derivatives ever mean anything to the operational Euro... but, considering the EPS      DOES   jive with the GEFs tele's, that makes me linger over the idea that the Euro's just being a douche-bag

Imo the OP Euro has been more of a douche-bag lately than ever....
