Models are beginning to edge towards producing precipitation over Cape Cod and Eastern MA for the coastal storm this upcoming week, and OES and a potential inverted trough.  Any chance the HIRES NAM and NAM and SREFs are right, even EURO shows some moisture clipping Cape Cod come the 16th.

Hires nam, nam, srefs, all utterly useless at this range.

Heh, no one asked but ...kind of bored with coastals after 2013 anyway.  Two blizzard warn events totaling nearly 20" of powder here, with wind gusts to 50mph in sub-freezing cold.  Been there done that.... 

 

I think it more interesting when something happens less than expected... We haven't had that, either, just saying. 

 

But I'm with Ray and Jerry... when it gets to be a grind this way, even I find a day like today, with perpetual road mist at 33F to be off-putting.  I was heads down at work anyway, but I'm already psyched for TCU and the smell of humidity.  Distance thunder rumbles in a Severe Watch.  I really can change gears on a dime with this stuff, and take my interest in Meteorological events into a different season in a heartbeat.  If we SE ridged out and did something anti-El Nino, well... I'd be fine with that.

Anyway ...having said all that.

 

I suppose 144 to 174 hours has some interest.  There are bundles of v-maxes pearled out below a SPV out there in the Pac, running east around the 40th parallel... In time, the models seems to fuse these into more like 2 or 3 distinct jet cores that slam into the Canadian Rockies around 72 to 84 hours from now. 

 

All models have been wavering on amplitude with this wind debris once it is ejected E out of the Canadian Rockies.  I'm having trouble with the PNA, and just what the index really is.  The CPC gang has a rather dullard, N/S looking curve... while CDC has two distinct spikes ranging close to +2.5SD. Be that as it may, so long as the index is statically positive, at just about any time, a trough scooting E of 110W might end up being more diggy when it comes to actually scoot E of that longitude - particularly if heights pop up on it's azz and supports wave kinematics.  Also, noticing the heights over Florida finally relaxing prior to hour 96. 582dm S of Miami, with balanced mid level velocities only 25 kts, usually means the flow's compressibility has returned. In other words, ...S/Ws encounter less shearing as they pass into the TV.  

 

It's a correction to get there, but there are aspects about the flow that "could" support some more of a deeper signal into the OV/TV region out there in the latter middle range.   

 

But ...given this season's remarkable propensity to deconstruct any possibility of cold intersecting with storminess here in the E, it might be also worth it to ignore this thing ...lest wasting time, too.

Its still going to end up a below normal snow winter, the only exception would be we get a KU event which is entirely possible but right now my guesses for the bigger cities on winter snow are BOS - 28, NYC - 18, ORH - 55, PVD - 22...thats pretty disgustingly bad, I'm assuming no KU, if that happens then those could be at least 12 inches higher.

amazing given the expectations going into this winter

It's a good thing we can't forecast 7 days from now let alone 20-30 days from now or I would actually be remotely concerned about people guessing about first week of Feb.[/quote

My goodness, you are so right. This guy that Kevin quoted, says his "guess" is cold and dry for a period 3-4 weeks from now. While that ofcourse could be the case, I certainly wouldn't be hanging my hat on that "guess" either.

While this dead bad pattern could continue for the rest of the winter, I'm choosing not to believe guesses like that at this point in time. There is a lot of winter time to come, and all the long range guesses from all the promising signs this autumn, haven't worked out so well so far either. At this point, anything is possible with regard to the rest of this season..nobody really knows what's going to transpire.

I hope Ginxy is right...he may be?

As far as SNE is concerned Winter may gradually work it's way from E to W this year with at least one kumbaya event for all. In the meantime the only surprises may be how cold it actually gets.

I like to look at this graphic for pure entertainment but sort of gives a quick summary of the model run because its usually fun to see what type of fantasy land storms are out there... but when the second half of January includes an entire 384 hour run of the GFS and pretty much keeps any cummulative snowfall of 6"+ north of the border, its going to be a boring time frame, lol.

 

Congrat's to James on Cape Cod MASS.  But overall for a 2-week prog, this is pretty dry across the entire US for snowfall in the last 2 weeks of January.

Just loop the run.

Yeah I know what you mean Im just joking...if you printed out total QPF for New England stations it was very dry deterministically, but you guys looked prime on one of those.

If that happened verbatim though that's a kick in the ballz, if like 4 lows pass just far enough off shore for light snow on the beaches and cirrus over ORH.

I don't think it will. Ridge is near Ak and even Bering sea.

Kind of a weenie Euro run in clown range...it gives us a clipper/redeveloper out of 1/21 and then looks primed for 1/23-1/24 with a classic Scooter Canadian Praries high pressing in as an overrunning OV Valley runner moves out of the southern states.  These are the types of storms we will have to try and get snow from at least initially in this pattern.

I would rather it not show something good in clown range tbh.

The Laurentians FTW. 

 

I feel that January is a rather cold and dry month anyway.  At least in NNE, the best skiing is always February/March when the most up-slope happens.

4 days in a row for 1/21 I think
