Really? They're very well protected... it's almost impossible to get decent waves/swells in there.

New London better Mystic worse but yeah what I was was saying was they would be more impacted by swell flow than BDR HVN. I wonder too after seeing Sandy Point practically eroded away about Bluff Point CT in future storms. Sandy Point was their natural breakwater from direct Ocean impacts. It is going to be an interesting this winter with basically a whole new ocean floor and coast.

00Z Euro is actually interesting for us here in the Berkshires. While it's not an all snow event verbatim, the deformation feature may actually help to dynamically cool the atmosphere to the point where wet snow may fall and accumulate. The Euro is picking up on this better than the GFS. This is how we get early season snows without a very cold airmass like the one we had on 10/29/11.

Notice the cooling showing up at 850 mb NW of the low due to the deformation zone and its associated dynamic cooling from stronger ascent and precipitation generation:

Good Saturday morning... hey if you have some work to do on the weekend, at least its snowing, right?

Snowing pretty good right now. First accumulating snow to the base.

Same thing here in Lake Effect Country :)

Nice coating on the ground at 33, looks like snow showers will continue for another day or two with solid NW flow of the lake

Looks to me like the Euro phases too early. You really want the storm to be bombing just off the shore with strengthening frontogenesis and strong synoptic scale lift as the storm gets going. The early phase and cutting off results in somewhat more meh synoptic scale lift and as a result the 700-850mb level doesn't dynamically cool fast enough.

Was there an under-the-radar upgrade of the NOGAPS model ?!

holy crap! The 00z AND 06z show remarkable continuity and both suggest a whopper winter storm/Nor'easter for SNE

is the modeled path likely in your opinion john, seems the look of a "NJ model low" or even a "DE" model low tucked in.....were or are still in favor over the further east nogaps path. i want to know if climatolgically the nogaps track is supported

because to me it seems like storms seem to take a few popular paths (sure none are exactly the same) but it seems there are several path's of "least resistance" that LP /noreasters take " and i could be off in the premise ....but wanted to know if you understand what i'm saying and agree

Om goodness at that Cocknadian!

This may just be the autumn and winter of the Phase. You know ... that may also be another characteristic about the new paradigm Will and I were once discussing, how back (really) toward the middle /end of August we have tendencies for 90W L/W axis refits, and that is ... perhaps wave frequencies are more constructive as opposed to deconstructively interfering. Interesting...

Either way, the blend of the "dependable GGEM/NOGAPS 00z runs bomb on down to 973mb with choking snow for interior SNE - rain by Ray. Hey...Raymond, "Rain Man"

we should just start blithely and annoyingly referring to Ray as Rain Man.

Anyway, at this time of year, any snow anywhere is pretty lucky. In this case, it's yet another hook-and-latter scenario, and there for the cyclone backs into the cold while bombing, as opposed to maturing on a SW-NE trajectory.

Okay, the Euro would start as snow but notice some differencec here, notably ... timing.

The timing of the Euro phases faster, so that the capture maximization of intensity happens quicker down along the MA as opposed to a latter capture and bombogen rate up along or just off CC. That profoundly differentiates the handling of the thermal fields, and ultimately ... ptype, during the event. With no run really showing much statice +PP N of the area, there isn't really a way (particularly over a bare ground and still relatively warm ocean) to hold marginal cold in place.

Either camp is right within its own framework, but over the long haul, common sense, based in no small part on performance/verification results, should bias one justifiably toward the Euro. Haven't seen the GFS or their respective ensemble means but going to do that now.

Also - just a quickie. The Day 10 GGEM/Euro both show another appropriately times cold trough incursion into the TV while there is yet another interval of TC potential approaching the Bahamas. I just found that interesting...

For now ... I'd go with a 00z Euro/06z GFS blend to fit in best with climo for a D4-5, then as it gets into nearer terms mold it either way. This offers some early event snow for the interior els, with cat's paws on windshields elsewhere, then everyone is raining clear to the Berk's by the time the system finds its greatest intensity.

More than anything else, it should be more looked at as encouraging that we are now just after H. Eve and have 2 important events on the EC. Without the presence of Sandy that interval was fraught with coastal potential - Sandy obfuscates that some.
