Hmmmm.. not still smilin “ ?

Ear to ear today brother.  You see glasses half empty and that's cool. I look at my full beer and say man this is going to be good. Enjoy the snow while you can and don't worry about the rest of the year. Better to have lost than never had I believe you said.

EC storms don’t have any impacts to midwesterners so they likely don’t even look. Screamers and EC storms both affect us so we care about both. Huge difference 

It’s all relative bro.  As Will said and others said, the cutter can shift 2-300 miles and it’s still a cutter for us(but it has huge impacts for the folks in the lakes and midwest when it shifts that much).  And that’s all ya need to know. A snowstorm for us on the east coast doesn’t have that wiggle room. Move it 200 miles west and it’s a cutter here again. Move it 200 miles east and it’s a snowstorm for us. Very small window for error here.

To be fair, I haven't been looking long term much this week with the impending storm. The PNA not responding as hoped/expected is more of a risk than a strong PV, agreed....I guess if that were to happen, then hope you are far enough north to avail of the blocking.

People forget how many great years featured a neg PNA. Odd they clue on that and ignore the negative EPO AO NAO solid signals on teleconnections.

This is an issue I have and I fully admit. I’ll enjoy the snow all day Sunday, but it’s tarnished and not as enjoyable knowing it’s all a dream by Tuesday night .

Its the obsession over the tendency for blocks to be displaced southward....while its important to remain mindful of it, you need to be careful about dismissing the notion of blocking and assuming that will continue to be the case moving forward.

I lived too many years just like this but am much happier now that I don't.  Embrace enjoying each moment, whatever they may bring, and make the most of it.

They always get porked. It's been pulling teeth there to get a decent storm last few years.

It has to be tough being a snow weenie over landlocked terrain and having to rely on the luck of the track. We at least have a permanent natural baroclinic zone to work with.

Beer?  At 9:00AM?  Been a while since I've done that

Re the 10th: the last 4 or so cycles kept carving the trough bottom SE in the operational GFS.   I haven't been looking at ens due to personal energy budget issues and being sick of it all for a little while...

As of the 12z rendition this morning ... that's already moving a wind max and associated PV field under L.I.    The surface position with a fanned out gunk warm sector failure look is purely a function of failing surface high pressure and colder BL resistance mechanics - there's no resistance, no Miller B

The hemisphere just didn't time well with that trough. If there was more CAD and high up there, drilling any trough bottom and wind max under one's latitude would likely result in a different reality than what you are seeing in that model's cinema.  

I still think we are heading in the right direction for the 13-16th. If one has to be told not to hold onto any one model solution from this range than they really should change engagements to save the quality of their lives... 

The pro is that we have a shit ton of cold air across southern Canada by then, with spill over episodes.  Troughs moving by NW will likely tend to tilt their veritical vortex structures and send that "SWFLow" type system result.  But it's not abundantly clear troughs will all do that in that time span. 

Con, they seem to be trying to do so overnight because the -NAO blocking was repositioned ( think Charlie Brown) just enough to allow a storm track to curl NW earlier on.  That could go the other way.  If the NAO does take the ball away then we suffer the cold roll-out into rain alternation deal, though. I'm not thinking that happens at this time.

prob shouldn’t be using OP runs, but there’s a big disparity here 

I feel like the CMC makes more sense synoptically, but who knows at this point

Just look at the NAO region. If we don’t retrograde that block like the GGEM shows, then we’re gonna be be a cutter-happy pattern where maybe we squeeze out a SWFE if we get a well-timed high, but largely a much more hostile pattern. 
 

The NAO is the key to having a good mid-month pattern. Models have been flip-flopping on that block….I’m not going to be optimistic until there is good agreement it retrogrades. If you can retrograde it well west like that, then it’s a really good pattern. Otherwise we’re probably gonna be much warmer and on the wrong side of a lot of systems.

at the same time, i think the lack of retrogression on the GFS is due to the fact that it buries everything out west and you don’t have that final wave break

The GEM looks like a demon sticking its tongue out at Pope and QQanon.  These are really different outcome for 50million+ people.  The nature of the NAO seems to be the entire ballgame.

Do model suite tendencies give us any clue?  I thought it was the Euro that liked to bury energy in the SW, but maybe that was before the "upgrade."

Also a pretty huge difference between EPS and GEFS. GEFS don’t ever really show a good pattern and reloads the big western Canada PV type pattern at the end of its run. The EPS seems to have a lot more El Niño influence and doesn’t have that. It also retrogrades the NAO block better. But there’s differences in the N PAC too…it has a low out in the GOA underneath the EPO/WPO block (seen below)

So it is a bit of the GEFS vs. the GEM and EPS?  Sort of I guess.  EPS in between?  That would be cold and dry if it stays that way.

Most of Maine is in trouble again . Hopefully they prepare this time and get out of state crews in 

CMP I know didn't bring anybody in until after it was already underway/after the fact. Depending on rain flooding was by far the more consequential thing from the pre-xmas storm. Up by camp in Rangeley there is a lot of damage.

Are we talking into Feb with the garbage look or are we looking to turn around regardless there?

Sure there was wind, But the largest impacts was Snow melt and rain with washouts and flooding.

The answer is really just simple math….

True, also many of our snowstorms are Miller b or late-developers which models will struggle with putting pieces together, while generally cutters are fully formed and mature way south and west of us so it's less moving parts coming together

Just adding to Will's post above ...

 ...the GEFs seem to be trying to lean more GEPy on this 12z mean, as already by D9 we see a more western limb -NAO expression .. .even merging with the eastern extension of the EPO domain.  Heh, you know, I've always wondered if there should be a mid Canada ( >60 N) teleconnector domain defined
