I agree, will be nice to see the Euro have a run similar to last nights and we are in business...

Won't change whether the storm is coming or not and there's nothing that it can show for you that will be much better than a gigantic low pressure passing near the BM.

The cone narrows. I could see the low still getting a little further NW particularly for ME/NH, but unless the 5h adjusts it can only get so far NW. I really hope it slams the ski areas, could care less about the Cape this time.

yeah verbatim...there's actually rain up into extreme se ma/cape etc for a time on this run.

The bombing low moving due north should at least help keep a decent northerly ageostrophic component...but yeah, it may not matter verbatim this run to keep it all snow for the Cape.

While it appears the ridge axis is a bit further east...slightly it's also oriented more SW to NE ish than S to N...seems like this extra little tilt allows for the trough to dig back west a little bit into part of the gulf-coast States this could help to hold back the southern stream energy a bit more allowing it to potentially take on a negative tilt earlier which looks to happen.

For those who are interested, here's the forecast qpf for the last three runs of the GFS:

GFS122420100zanim.gif

Right now, I'm cautiously optimistic that the westward trend that commenced on the 18z GFS may be a real trend. It was confirmed, at least to some extent, by the 0z NAM's slight improvement over its 18z run and now the 0z GFS. It will be interesting to see the ensembles and the other models (GGEM, UKMET, and ECMWF) that will run over the next few hours.

It's an issue with the 5H trof swinging down from Quebec that mucks it up and doesn't allow it to really wrap more N and W with the deformation. Of course we have 72 hours to change that configuration. :) Instead it gets booted.... But up to that point it certainly was quite a comeback for this thing.

It has been a problem from the get go, And don't know if we move it quick enough to allow this vort to come NW, I need it to hook into the GOM then we are in biz..........

UKMET has the storm pretty far east but at 72 hours about to wrap it up. Might make a pass but too far out. And frankly I have no concern about the crazy uncle.

Let's be honest...there's only one more op model tonight that matters and it comes out at 1 AM. We'll look at the UKMET and the GGEM out of formality, but I doubt anyone gives a damn about them.

yeah i'm not overly concerned...plus...it'll do what it wants to do. in the end, my issue is getting it right.

the soundings definitely are warm down my way for about 6 hours or so on that run despite screaming NNE flow. the one plus is the low is so remarkably deep the warm look to the soundings is offset a bit by the fact that the column is shallow because the low is so ridiculously deep.

it's all a matter of miles really. won't know any of that kind of stuff until we are much closer in (assuming this doesn't make a giant leap one way or the other).

one signal that remains in tact is some ferocious wind along the coast

Right now IMO it can tick a couple or so nautical miles nw but as of now being closer to a consensus we shouldn't see huge flip flops in the low position at the BM. But remember, you have to start to talk abut precip type issues if it does go a couple or so nautical miles NW from it current predicted position.:snowman:

Well we got much more digging/amplification of the trough this run and ticked it a bit west. I'm not sure we can go much more west than this.

yeah but is there something that can be done about that quick cut ene as it is bombing near the benchmark? The overall track maybe can't go more west but could it come a little further north...then we get 12 instead of 6-8
