Post snow-pack apocalypse chance for wintry weather heading into Christmas morning

[jamesnichols1989]

Yeah we just need the trough to amplify further east than currently modeled to allow the colder air to filter in faster.  Tough to get it here before the precip ends.

I will be interested to see the flow the NAM produces at the surface for 84 hours through 96 hours when it gets in range.

I dont see anything there...lets move on post xmas.

one thing to watch - and the euro actually bit on it a little bit this run - is there's a ton of energy that has to pivot through behind the front and a lot of guidance has a weak inverted trough sweeping across the northeast. euro this run actually has some light precip with it.

What day?

 

Christmas Day, that would reinforce the northerly winds over the Bay and allow for good Ocean Effect Snows.  CMC actually brings the -20C 850mb temp line just off Cape.

What day?

 

Tuesday night, but that looks meh. At least nothing to get excited about in most spots, maybe a Cape coating.

[jamesnichols1989]

That is a very potent trough coming overhead over New England.  CMC says -20C 850mb temps over SNE.

Jb and Phil make a good team

Keep fighting the good fight.

@BigJoeBastardi heavy snows for Cape Cod, MA, northerly winds bring ocean enhancement

[Clinch Leatherwood]

Xmas looks like a legit threat to me.

@TollandKev: @ericfisher There isn't one person that wants this weather around the holidays. It's awful, pisses people off and has destroyed our snowpack

In what context?  The frontal wave or the inverted trough, or ocean effect snows?

[jamesnichols1989]

Its almost like the 18z NAM went bonkers over some intense PVA in a shortwave and brought the whole trough towards a negative tilt and closed an h5 low off over NNE.  I think if it trends southward with that vortex we might be in for a little more than a surprise, especially if that shortwave behaves and we get north, northeasterly flow going.  NAM has an inverted Christmas trough just like the EURO did.

My just isn't big enough for that

Thoughts on an inverted trough for some Christmas fun?

lol funny thing is, except for us freaks, most people were happy about the snow melting.

Most of the time the inverted troughs fade in favor for a real low.

We don't like those people

Hopefully the Cape and coastal areas can grab a coating

[jamesnichols1989]

00z EURO is in favor of the troughing signal over SNE, inverted trough signal, and SREFs are increasing in favor of OES for Cape Cod, MA east of HYA.

[Damage In Tolland]

Anyone with precip access..Did the Euro still have the inverted trough with light snow Xmas Eve?

A few hundredths on LI. Maybe flurries to the S Coast?

[CoastalWx]

Move on

[jamesnichols1989]

HPC thinks there is a 20-30% chance at snow of >1" for Cape Cod, MA sometime between 12z Tuesday and 12z Wednesday, also SREFs are beginning to like this period for snow, OES.
