Typhoon Tip

I saw it ... it seems the PNA evolution is playing havoc with N/stream wave spacing and timing and the op. versions are cyclically relaying/emphasizing between regions of amplitude ... this is an “on” run

I posted about this earlier… The northern stream has not been handled very inconsistently ...earlier in the day the runs almost completely abandon any northern stream involvement at all and here some of these 0Z runs bring it back big time cut in and still day 6+ ..,so you know this could be an on off deal for the next couple days

Probably worth watching that 4.5D foreground curling neutral under LI for shits and giggles ... it’s been consistent in recent cycles and swipes evolving albeit quick hitter CCB head of chilly rains SE heading into blue bomb climo .., wouldn’t take a whole helluva lot to parachute

Actually ends up bombigen’ed pretty good near Portland Maine but “Bun”lieve it or not that could’ve taken place sooner… It tried to escape a bit of the vestigial southern stream and attendant early convective out to sea ...slows the inevitable from happening - it probably in reality would take place sooner that’s a deep humdinger there but ooph

It’s having trouble with the phasing kinematics but ironing some of those out and probably coalesces into a pretty significant deal

Looks like the GFS arriving steeper in the northern stream

Oh geez ... snow? snow - ... I mean it could be f'n sunny .. . once the continuity blew up yeah my point is no one knows. you don't not you personally you know what mean tho - The PNA rise/mode change argues for something in the 70-80W by 50-35N box with wiggle room obviously... and in a marginal atmosphere ...there isn't any wiggle room... Anyway, I don't think it's apt to sunny ( that's kidding..) but there is huge uncertainty duh

Wasn't today like an "embarrassing win" ?

Anyone averring declarations over next weekend's system should be advised - The entire N-stream and pattern morphology subtended beneath just got shredded of the previous continuity, over the last two cycles ... it started to unravel 00z and really it's blown apart worse in most guidance all day. You don't know what is coming at us next weekend ... All the while, the GEFs still honking a concerted PNA arc heading toward D10 - for all we know this is model black out nonsense... .... I don't buy the Euro sell beyond 90 hours anywhere east of the Rockies ... The cohesive singular vortex idea that was suppose to dump in..then wait on the N/stream for the 'ally 'oop' phase, has gotten obliterated compared to previous cycles .. Hate to say but smacks as Miami rule rearing it's ugly head ... heights in the south ...kill yeah when they are planetary anchored, even subtly anomalously high, and not merely rolling out ahead... What happens? the velocities physically increases as that thing dumps in ~ 72 hours and as such ... tears it open and meat shears it to entrails.. ... The Euro tries to maintain cohesion beyond D5 but that's probably 4-d conservatism ... and the GFS wonders off with a faux Dec 2005 redux but only at 500 mb .. ugh... It's amess... Agreed with the previous Met poster that the 850 mb thermal layout is odd everywhere - ....

Haha. Man I think you need anger management… it was an op ed you responded to - an op f’n Ed Sorry for any condiscending tone - But you were reading in way too deep then ...especially when I’m trying to defend myself after the fact

What are you talking about - better than what. I never said 192 hour prog is reliable. It’s a weather board ... you know ? Like discussion about duh ... weather and stuff?? It was just an op Ed geesh. ...making a comment on how odd that look is

You should probably just stick to “GW”and leave the “A” out of it

No one said that global warming was why anyone storm is warm - where was that ever read ? There is an odd meteorology in the GFS solution… Which seems to have escaped everybody’s attention that’s trying to refute in knee jerk argue without thinking! Who gives a shit what your argument is about needing cold air and snow ...obviously WRT the 192 hr it’s the gdamn oddity of 510 heights over rain column - nothing else Look I wrote an op-ed-intoned piece for anybody that was lucid and objective in the read, and apparently some just don’t like the content ...

This isn't Meteorologically sound as reasoning - bold a, b, ...you should not "feel" anyting when one admits to an op -ed post... c, ... you are wrong if don't think HC is having a direct impact of disrupting/modulating previous climate signals - to wit the ENSO cycles is a part. Sorry - I know what I am talking about.

Correct ... I'm sure the CMC folk probably derive their indices, as do the JMA and Euro offices ... etc etc... The CPC's ( fyi - ) uses the middle tropospheric geopotential height anomalies across a grid.... Where they employ Emperical Orthogonals ( it's worth it to look it up and study it for a couple of hours- it's a nerd's paradise ) to derive polynomial expression.... where by they can be solved quadratically/sqr completion to determine the roots... Positive means as such and vice versa... It just so happens that by convention/latitude .. .negative in the case of EPO and NAO means the heights are higher than normal ... so PNA being more mid latitude ends up being negative as higher heights in the S... More over, the AO is a circumvallate extending S from the N-pole in all directions/radii equidistance ...I "think" down to 70S but don't quote me - can look that up.. Where's the EPO and NOA domain spaces extend above and below that ~ latitude by west-east longitudes.... such that they overlap the AO in partial eclipse, and can at times differentiate from the AO... That is why/where art is involved ... in/if the AO is falling to neutral, but the EPO and NAO are negative ... that means it is likely the AO overall is positive but happens to have some positive heights/blocking sharing the domain space with the former... and on and so on... They don't always move together either...sometimes changes over in Eurasia will tug the AO in an opposing direction to the Pac/Atl forcing and there's weird shit that transiently happens...

Yeah, okay gotcha ... I'll only add that "SNE in early December" takes a back-seat to what is actually on the chart and/or verifying - climate doesn't drive the latter, so if we're in the business of closing off heights so deep and physically bordering on impossibly raining at that depth ...we're talking about apples and oranges

It's okay to disagree ... but about what? I'm not even sure we are discussing the same facets - ... are you talking specific events or climate - if one wants to hone specifics, you can disagree all you want but having a 510 DM height center quasi-closed off and passing over head while it is raining is exceptionally rare and strains believability... As far as the climate change being 'under the radar' of general awareness - that's not even refutable ... Climate doesn't change one day - yeah...I don't know what is disagreed upon but okay

He was responding to my climate jest ... You seem to be adding commentary about a specific event ? which one ... As far as specifics: I'm intrigued by the D8 depiction in the GFS ...and even the GGEM is doing it to some degree ( pun intended ...). it's closing off heights so deep it strains believability that the column wouldn't be colder ..

I think there is some value in the notion that climate is insidious ... changing under one's nose and they may not be aware of it... " it's just so slow that we end up here and people don't recall a "switch" or definitive event that demarcates when a seamless boundary passed by - but it's "climate event horizon" stuff - you don't know you cross over the point of no return... " I was just making an op-ed out of it... "..In 1946 I don't believe we necessarily had to have a -EPO to get things going... " As far as your bold...not sure I agree that a month of anything logically follows... Ever heard of a phenomenon known as a "blue norther" ?? it does not take as long as we may think to clean out continental regional scope and scale of warmth. Blue norther is Plains phenomenon where cold dense air mass funnels down the lee side of the Rockies ...it gets sort of caught under the sounding and geographically/topographically the air mass continues to roll S under the environmental flow until it's momentum/pressure continuity is normalized.... Usually not stopping until pretty deep in latitude, too. It's almost like our "tuck" phenomenon, but over a much, much larger continental scale, really - ... It can turn balmy 74 F late autumn day in Dallas to 19 F pingers with fr drizzle in a single hour in very strong knife events. I wasn't intending to 'raise eyebrows' in that sense - more like droll with a soupcon of seriousness.

510 DM heights around a deepening core over L.I.... .... rain 510 DM heights over top 534 dm thickness - ...whaaaa ...

Normally I roll-eyes when the social tenor in here 'memes' on a popularity for grousing with that song and dance that 'pretends we're not trolling' But, hmm in this case, in deference to the lack of cold in Canada, despite the favorable PNA look ... I have to say I am impressed folks are objectively/lucid to the idea in this case. I remember opining either in this social media outlet, or emailing to some Met once ...probably both, that about 7 or 9 years I notice a difference setting in. It seemed we crossed a threshold. Our flop direction when facing modeled marginal looks started not going to -1C ... and in fact, going the other way. Maybe it's just another under-the-radar metric in how our region expresses a warming world. Our flop tendency --> +1 ... I don't mean that from any empirically derived hard thing ... Just an observation/anecdotal in general. It seems we are more and more NJ-like. I know ... I know ... desperately cobble counter arguments but ... okay. Maybe? But just keep in mind...climate change is happening And if/when that change is in the 'up' direction ... ? See ...one of the beauties - and saviors of sanity - about the cosmos is that reality still exists whether people want to believe it or not - lol... Anyway, the climate bands are migrating N. And seeing whopper +PNA's over 10 day stints approaching a proper winter climo month ... fail to load cold ... mm. I don't know...In 1946 I don't believe we necessarily had to have a -EPO to get things going... nah. It's endemic to modernity and where we're heading ... it's just so slow that we end up here and people don't recall a "switch" or definitive event that demarcates when a seamless boundary passed by - but it's "climate event horizon" stuff - you don't know you cross over the point of no return... So, being a little poetically/symbolic there but still - But, I remember saying ... it's like in the olden days we could count on a +2 C, 850 mb thermal layout in the CCB of coastal, on any given D8, winding up isothermal blue menaces... That just doesn't seem so reliant in anymore. It's like the "synergistic" tendency? Those ephemeral results that only exist while the storm is happening, emerged warmer now than 50 years ago... at all scales...dailies/events/ ..to large synoptic evolutions. Patterns find the warm flop direction with increasingly less excuses in getting there.. anyway, without a direct servicing cold ... the base-line does immediately go back to 1 degree too warm for anything ...

Right ... hence the operative "every cycle inches closer" phrase ... hello - that run sucks by the way - one shouldn't wanna hold that for 32 cycles any more than a steaming pile of feces ... but if you say so Nah, the runs have been - subjectively ... - materializing a cooler profile - as in 'trend' ? - and a deeper system, which frankly is more likely during that limb of the PNA rise than the foreground system ever was...

every model cycle(s) inch the region closer ....

mm.. 12z oper. GFS isn't an "inland" solution... no sense in overstating the matter lol. I mean there may be some subjective hand throwing but, inland is more definitively west... Like, PA with only paltry commitment toward a 'dent' on a warm front. Now that's inland.. . This? this is a coastal low... It's just not ideal... We don't have -8 C 850 mb entry temp slabbed down E along the coastal plain while a 974 mb low passes a stones throw east of ISP no. Folks need to be "fluid" in their chart interpretations - I suspect there's too much snap shot grousing that happens. To each is own... sure. But that solution is fine for this range in a rising PNA.

Word ... I just saw the 12z GFS re the foreground deal and it's really middling as a cyclone depth at best... barely less that mid 990's MB ... It's spacial ... large though - so in that sense/math it'll carry on with a decent extra-tropical ISE ... It probably still - as is - has enough mid level tropospheric wave mechanics to really have been a bigger deal .. but this blown open busted ravioli thing is very spring -like... it smacks like a combination of correction working on it.. One, the relay off the Pac may prove weaker than the model zealotry ( heh ), but it's also neutralizing early April D11 bomb that ends up weaker because seasonal migration exposing the weakening thermal gradients ( baroclinic layout) due to the sun... Only here? we have pallid cold and GW cooking the fronts to death... lol Nah... kidding on the GWl - eh hm...a little - but if we did have colder air, we probably would have changed this in a lot of feed-back reasons toward an different total evolution. Cold BL resistance forces coastal ...and that feeds-back by height falls then drawing the deeper layer E...and that also conserves the faster flow better... Probably spend more time than I care to on this thing ... it's thee transition system the heralds the PNA change - I've maintained that ... We'll see what happens later on -
