12/30 Coastal - Snowing Our Way Into NYE

What is your take on this ?

I think a 2-4 deal for near CT/RI maybe towards BOS..maybe 3-5 SE MA. It's highly dependent on how quickly this develops. If that comma head gets close...look out. Also, the vortmax will probably deliver some snow even for wrn and ctrl MA. I don't see a big reason to be bullish now, but I am well aware how close to a big deal this will be for some..esp SE MA.

Yeah that's pretty much my thinking as well. If it goes to town earlier lookout, but for now I think too little/too late.

I also don't think the air mass ahead of this is particularly conducive for my area

I joked with Will that if this got close enough, it could be a mini Dec '04 for you where you go from mix to white out paste...lol.

But I agree, I don't really see a reason to be bullish at the moment, just mention the "what ifs."

Yeah haha I was thinking about that earlier actually (12/26-27/04)

If the antecedent air mass was better I think I'd be more interested in this delivering a warning type event..,right now I think a decent chunk of qpf is wasted on liquid/mix/non-accumulating snow

I would take that and run! Not to go off topic but the flooding along the coast here today was a little more than what I was expecting, impressive storm in that regard IMO.

One key to watch, is the Plains ULL.

Agree with your comments in response to me above re the comma head. I just don't think at this point it pulls together in time to get me, maybe out towards chatham or Phil. I'm wide open to changes and the ULL is decently impressive so we'll see. Tonights run should consolidate the solutions I hope. I just don't see any support for the larger regionwide totals as of now.

Apparently not. lol. It's amazing what happens to a meteorologist who does not agree with the consensus of this blog. I just read through 4 pages of people talking about Matt because he thinks it is going to snow to the Canadian border.

I don't see how you can disagree with him on the point. If you look at the qpf output from the models, this is true. Even the CA/US border receives some amount of qpf from this event.

In defense of Matt, he says he expects a decent snow storm. He has not thrown out any totals yet, so it sounds as if we are assuming he means 10"+. Which I am sure he does not. But these days, a decent snow storm in the coastal plain is 3".

And asking what is rationale is, what do you want him to do? Get into the atmospheric dynamics on air? lol

This is true - he hasn't actually tossed amounts. He could be thinking 2-4 lol

He didnt give amounts but said a plowable snow for most of southern NE.

I'm waiting for that shortwave over the southwestern States and that trough over the Pacific to get into better data assimilation area before I give this one up. Western Texas for the southwestern US shortwave is my target area and for the trough over the Pacific I would want it to just get close enough to the coast. I'd say tomorrows 12z runs will have a better consensus than tonights 0z.

I forgot to say that my point was that shortwaves that ultimately become major players along the east coast coming out of the southwestern states have usually had more model error associated with them than normal. Take this past storm for instance. We saw the shortwave trend further south in Texas as it came out of the desert southwest. That's how a lot of the snow forecasts for Oklahoma busted so badly. It has happened before and that is why I would like to wait til this gets into Texas before saying we have no chance at getting big snows.

0z NAM has initialized the trough and shortwave over the desert southwest much stronger than 12z and 18z. This autocorrection was expected, but I still feel it is having some sort of error after initialization due to the grid being over a nonhomogeneous terrain. Still think our best idea of the strength of this feature will be tomorrows 12z runs but seeing this correction already is a very good sign.

Looks stronger through 18/24. Could be pulling a fast one but flow is more amplified for sure early on.
