Typhoon Tip

It's fascinating .. that sliver of warmth like that. There are several conflicting schools, re the weekend's shenanigans: That much high pressure genesis and roll-out through Ontario typically doesn't stop moving S and stall along that axis as that product illustrates. Almost invariably that would end up correcting S as the period in question goes from late mid, to mid and on inwards to the short term. The 2nd school ... this is a uniquely anomalous pattern - I feel - but one that is pretty well described, so should not be an opinion shared by one individual. The flow is fast, because there is a monters ridge in the S. It may not be spatially engulfing the entire U.S. like they do in the summer, but that is purely a function of ambient, boreal heights of winter pressing south. The speed is a direct result of that compression. But why that is important is because .. this ridge ain't goin' no wheres ( most likely..). It's in part R-wave constructed, but, the construction is footed on a bloated HC tendency in the first place - which is a planetary heat source sink balancing and is thus much more permanent. Anyway, the two are in constructive interference... and that's all verbose terminology that hearkens to a ridge that's stuck. Thirdly... that anomalous ridging - I personally am noting ... - appears to be accentuating confluence in southern Canada. That's having an interesting counter, or offset lower troposphere factor in the temperature/thickness distribution in the NP-Lakes .. N OV and NE regions. We are seeing big highs routinely emerge across southern Canada and these are wedging cold as they would typically do.. .But, that sets up these regions with a kind of background potential of odd-ball sounding events, with big warmth flopped over llv cold. That sliver of obscene warmth slicing up like that ... kinda sorta does fit that exaggerated llv gradient potential, though in this case... the gradient is more horizontal than vertical. Still that warm air is riding over that cold wedge either way - we just happen to have it modeled right now as though the warm intrustion to surface succeed Boston's latitude. I gotta say, that much high pressure up there ... if Boston pulls that off, that is some seriously unusual shit right right there.

It's hard ... folks tend to "Stockholm Syndrome" effect when reality delivers them unrelentingly. But "weather" we are talking a political hostage scenario in the early 1970s, or matters of the vagarious wind, a similar phenomenon takes place. People begin to relate to that paradigm and concede. They start to think ..or more precisely, it gets harder and harder to imagine a different scenario and acceptance emerges. In this case, it can't get better Even I am guilty of this failing at times... I "try" ( failing miserably usually ) to be purely objective about matters, but when whatever goes on too humanely long I start finding reasons to justify it as an immovable new paradigm. Like, oh...I see why we are eternally f~ Kidding to some degree... I'm just not sure that speed stuff I've been harping really qualifies? Seeing as there are reams of papers by vetted sourcing that go to empirical lengths describing what folks either don't understand in this social media, or hate... digression Seriously though, in 2015 we were not really looking at a very favorable teleconnector spread in the first week of January, for the closing of that month. I seem to recall the EPO tanked around the 20th...and it didn't really start getting modeled to do so by the American cluster until ~ the 10th to 15th... But holy Moses, once that sucker arrive did it lock! I mean, it was like very day I checked, and the end bar graphs were being driven down like railroad spikes on a Georgia chain gang. By the time the given day that emerged -.5 SD on D13 succeeded D7, those intervals were had been pegged down to -4 SDs or deeper. I'm not saying this year is redux or analog by any stretch... The concept of uncertainty is paramount, and three weeks is loooong ass time in this business to assume shit man.

Know what would be really cool ... gotta go sci-fi for a minute, but, imagine if it stayed like that? Like two months of freezing rains with cool rain along the boundary ...and sunny where it was 60. It'd be like a glacial wall right next to it - heh

Heh, take away from this NAM solution is its behavior, not what it is showing on this run ... I realize "NAM still shows a crushing here " gets one to that excitement they're looking for ... but, these runs could end up being phantoms as others are also pointing out - might help protect one from disappointment if they focus on that. Historically the NAM does this in short term sort of 24 to 36 hour lead windows with these NW hiccups thing. We've seen countless times... Then it settles back - the bump E even by a subtle margin is exposing that instability. Yeah, it's just not a good model really ... particularly for gauging impacts because it does these synoptic two-steps too frequently. I think at this range if it isn't getting support from the other meso tools and/or the higher resolution/reputable G-scale numerical model types, one should put it's odds at success as very low confidence.

I wonder ... maybe the appeal of ice storm persistence out there in the extended is really just an artifice of the GFS stretching/progressive bias. It's got two cold waves out there, both sporting < 510 dm thickness air spread out over vast regions of the NP-Lake-NE regions, and keeps rolling them out, ...just in time for rain... So, 10 F to 55 F with no compunctions about wildly swinging variances in temp and thermodynamics that should otherwise be capable of creating storms that drill holes in the planet. It did this is 2015 ... That may be part of the GFS own bias type, to have to much resulting gradient because it has trouble curving the field and mixing at synoptic scales. Interesting... Either way, the -3 SD PNA while there is zippo cold signals coming from pretty much any other teleconnector out to the end of week two, doesn't lend to its massive cold dumps so it's a hot mess...

Yeah just my opinion is that the Euro and GGEM are playing into their own bias tendencies at the weekend's range, and having heights slightly too dug deeply in the broad circumvallate of the west is causing them to be too far N with that low over the western OV once it's been ejected and then has to climb the over compensated eastern height wall... Slight correction S may be warranted, but how much? The GFS seems like it could use a bit of rasping S given the velocities overall, too - so, ... not sure what to make of that, considering it rarely need to be reminded not to go polarward early to put it "mildly" And the first idea with the Euro and GGEM is speculative of course. But PF's product posting is pretty sick... It's amazing enough to see ORH probably 29 while it is 58 in HFD, but the step back appeal of having -3 to +5 F draped across southern Ontario with the 60 F isotherm up to NYC and CT is getting down right Plainian - wow... Fits the the narrative of HC expanding into the lower Ferrel latitudes ...

like being ghosted by a someone you love - just can't let it go... hard. miracles can happen tho, no discounting.

I wonder if that challenged "futility" record as it's dubbed in here. I mean .. going back hundreds of years ya gotta think there's a year or two others that blanked but who knows --

Halloween was the biggest event of 2011-2012 ... Not for Boston, but for the ballast of the area. Actually, I don't think Boston even really ever had an event that year ...like at all - maybe

That would be a fascinating experiential change there if those details of the 00z Euro solution play out that way. 00z Sunday ( Saturday at 8 pm - ) features a quasi-stationary boundary aligning roughly White Plains NY - Nashua NH, with 850 mb temps in the ~ +10 C range...probably an ongoing gunk warm sector with light showery spritzers running up along and to nearby in that warm sector, so not clean and warm dandy in that depiction, but definitely a balmy vibe relative to January climo - maybe 60. But at that time, big polar high looms, gaining weight and momentum, pressing toward/into Ontario. That boundary gets forced south to NYC by 12z Sunday morning ... and that should whip the region down some 25 to 30 F ... at which point there is a melange p-type overrunning in the area. Vastly vastly different sensible appeal going from early evening Saturday forward.

You think you're being funny but ... you're likely spot on I mean, the idea is that sloped sounding events would be favored because of that ... Increasing the gradient and the sped up flow, that tends to disrupt the ability for the classic Norwegian Model Low's various structural components. Not sure what your level of education and understanding is, but .. there are classic conveyor jets that need to formulate...etc..etc.. Systems tend to be smeared as they don't have the mechanics to overcome the background gradient, and so overrunning tends to happen more often.

Looks like a sleet bomb again .. for now. Obviously, this one, too, will be modulating across future guidance, sending social-media through the usual negotiations ... haha Anyway, here we are again with a couple of cycles worth of runs, loading up the extended with ice storm threats. It's interestingly persistent as a base-line 'look' this winter so far. A tenor that's been going on for weeks really, where intuitively mix/ice specific types of winter events would seem favored. Yet, we've only really received one meaningfully impacting event for that supposed potential. At least down this way. It could just variance getting in the way and masking a dominant signal. Be that as it may, in this case, we have the Euro/GFS/and GGEM ... perhaps some cross-guidance support then to lend credence. Notwithstanding details at this range, their's consensus there: fresh, new very cold low level wedging arriving/presaging a main thrust of WAA lift, that produces a QPF bomb over top an intensifying frontal slope that is crushed S by the weight of said high pressure as it folds around the east limb of the total baroclinic space. That sounds like an ice storm frankly - we'll see. But I do wonder if the other shoe will fall at some point and we end up with a 2.5 day steady state accreter at some point.

I get the impression that’s about as compact as this thing is going to get in terms of being in the same space and time with those two short waves… i.e. phasing. They may more proficiently yet but they’re gonna have to do it out towards the Maritimes as it takes time to phase. And the translation velocity the whole set up is just moving too quick While the wave interaction is contained within

False. Never said u were a denier factually what took place is you said, “it doesn’t fit the narrative “ clearly in deference to a conversation you were not a part of You often do this ... make cowardly underhanded discrediting/slander tactics. What I said was…”yes that fits the narrative” (Steve). cockeyed on this deny stuff; I have no idea where that’s coming

my horseshit… lol I’m bringing it to people’s attention that there are mounting number of scientifically vetted and peer reviewed papers about the subject matter end you seem to think I’m making this up? OK you can take away what you want or need to perceive but this is not me - you’re blaming the messenger. I never said anything about snow? Making sure people are aware of that I was talking about specifically the HC causing compression in the winter months which is speeding up the flow and that’s not really controvertible. Leave it at that As far as the storm ... the models are going to show what they show at an instant or a snapshot it’s not necessarily gonna be readily evident that they’re being stressed by speed. But clue as to the presence of speed surplus is incredible number of wind flags exceeding 100 kts in the H5 level and all these jet velocity above ...empirical set. But the other thing is that synoptically the wave lengths are being stretched long

The rest or baseline state is faster now than it has been in the past due to climate change.

This mid and extended range doesn't scream historic warmth to me for anyone living N of roughly the Del Marva latitudes... not that anyone asked - There's too much confluence modeled to swing through southern Canada and the correction vector should be toward increasing sfc PP along the 50th parallel up there underneath...which means the obvious down to 40 N. If for some reason we can tip toe through the next 4 to 10 days without getting a +PP in southern Ontario... we'd still need a well-mixed dry adiabatic atmosphere on long fetched continental flow, and so far, the warm sectors that - I feel - are over done because of the first point, are dirty anyway.

Again, ... you guys, we were talking about the speeding up of the flow stuff. You guys are exposing your fears and insecurities deviating that into snow so far..just a little here. ha. I couldn't give a shit less about snow. I'm worried about the evidences of CC in HC expansion and objectively attempting to speculate what it means for the future. Like I said, increasing heat increased PWAT in Earth's geo-physical interplay, so provided there is sufficient cold, ... duh -

anyway ... at some point the the increased PWAT probably would mean more rain vs snow, here... but that's who knows how long off. The conversation I was having with Dryslot wasn't snow specific - we were talking around the fast flow stuff. The stuff about snow is recent and another aspect. Theoretically ...expanding the HC into winter months should speed up the flow and it's being noted... That's an open shut case. And, is a climate change implication that Steve hates ... wah wah waah

I never said you were - I said Steve parenthetically

I think it has ...it's helping to snow more hahaha... Probably talking past one another. I just got back trying to catch up -

The wave length are unusually long - that is because of the fast flow... I don't have personal wants where this things take place... but the 960 low, typically is farther west in a "normal " r-wave distribution. I'm not going to argue what is correct. You guys just don't like the climate implication - that is what is not liked here

SNE doesn't mean shit.... You have to take hemisphere's apart in quadrature. Firstly.. come on Secondly, the climate models and theoretical physics state we increase PWAT potential in a warming atmosphere such that when sufficiently cold enough, more snow "in the last 15 years" absolutely fits that both science and the narrative ( Steve ) ...

I honestly have my doubts... I think we're in sort of uncharted CC waters here... The CC stuff and the expanded Hadley Cell is a pan-systemic, Earth-based problem... it's not a matter of reshuffling the rosby numbers and orienations and so forth. Even if the latter rouletts its way into a better configuration, does it merely situated over the top of and compress the heights? It's not like 1990 anymore. We have to contend with ... This is quick/snap search on the web to serve as primer, but there is a Climate report that links to hundreds of scientifically vetted/apprv paper material that goes into it deeper. but, https://www.climatesignals.org/climate-signals/hadley-cell-expansion means winter be f'ed if one than integrates conceptually into actual Meteorological consequences. This expansion didn't start this year...it's been growing in coherency ...particularly since the mega NINO of the late 1990s...It's almost like that even was a Terran-wide climate threshold point and by subtle geometries, we never really ever settled back/recovered to the previous dynamics. We are in fact, going up still ever since, and this year ? This is the worse I have consequentially observed the speeding up aspect, yet. Why would anyone wonder why the big Nino from 3-5 years ago didn't register as obviously in the global circuitry - it's because it's getting f'n burried in already an atmospheric surplus of latent heat in the tropics, so it's not triggering an atmospheric response. yet, those folks out there keep planning on winters doing a-b-c, because of x-y-z ENSO. ...it's interestingly debatable... There are no absolutes - some bigger by proportion anomaly can off-set. But, that by definition is rarefied so - Anyway, suppositional, but if we deal with this shit the rest of the way, I wouldn't be surprised. even if we get lucky ( anyway ) and get clocked once or twice and smugly use that to rationalize things as still being fine ... still doesn't change the reality of what's happening.

yeah .. right .. agreed. No matter how we dress it up and uber hyper drill into the texture of the thing... like I snarked to Brian an hour ago, the flow is simply too fast for phasing. I mean what you describe is really alleviated if the ridge in the west pops higher in latitude... But it can't, because the whole fuggin' hemisphere is moving a ludicrous speeds in the first place - one thing limits the next thing --> ultimately limits that
