Typhoon Tip

Some ensembles still trying to Bob the EC -

There are two variables that play in there: A, heat source and sink thermodynamics. B, source of heating Bottom line, uptake of solar heating cannot fall below the rate of the black-body radiative hemorrhaging. A, if the surrounding medium's heat sink is deepening, like lowering DPs ... seeya later warmth. A warmer DP sounding medium naturally means a shallower sink, the water doesn't hemorrhage as much. There probably is some critical angle the sun falls beneath where it doesn't matter, and the pool will cool either way. But a warmer DP early autumn may slow that some.

You guys need instant gratification ... jeez. Problem with modeling and extended favorable regimes ...if whether/even having specifics to monitor therein, is that you have to then wait a week - it may take ...days over days before there is 'excitement' It's like people lose sight of that, and two days and a couple of banal solution cycles later .... either forget that it's still out there, or because they aren't getting fun right now ..they flop like a five year old and have these "micro" melts..

what does "lg" mean in that context - start there

We've all got our run-ins with absurdo-turbo-snow rates. Three in my life. Two are tied, and one is a short 2nd behind. In both 1997 Dec 23, and 2005 Dec 10, I witnessed 7 inches in one hour. Both those occurrence were also book-ended by a couple of hours of 3 or even 4"/ hr rates, but ... once you've suffocated in a 7" hour it almost seems like 3 is light snow. Whole 'nother world when approaching the coveted 5 per hour rates. The other time was early February 1986 ( '87 ?...for some reason I can never remember the date on this one ). 5.5" in one hour fell in dead air, also book-ended by 2 or 3"/hrs, before a coastal finally kicked-in a CCB that put the final nail in the forecast coffin that it would warm up. This one had lightning and thunder ... I was skiing Nashoba Valley over here in Littleton when that first 2" snow-hour abruptly swept over the mountain and suddenly ... 1 mile become 50 feet visibility. 20 minutes later they closed the slopes because a double-flit pulse of blue light preceding seismic chest thumping booms - uh...yeah, get people off the lift towers, now! There were several thunder claps over that 5+" hour. That was a fascinating storm. One of those storm-memories that never fades. Totaled close to a foot off a forecast for 1 to 2" then light rain and mix. I hold this one as close to heart as the other two above - even though it's in 2nd place total-wise it shares the ceremony. This thing came on utterly out of nowhere ... To go from almost an ignorable weather forecast windshield wiper expectation, to a traffic-grid failing, deep winter storm realization is pretty f'n awesome. My father said that Rt 2 there at Arlington Heights ..the big climb up the hill out of Cambridge ...was a parking lot of cars fish-tailing but not actually making much headway up the hill. Somehow his pick-up made. Earlier that afternoon, ..around 1:30 ... the temperature was like 21 F when the snow started with those insidious tiny uniform aggregates of plates and micro dendrites. Like the menacing needle eyed hurricane. Small sometimes means BIG! I remember standing there in front the window as Algebra 2 was gathering when the teacher sided up next to me. I said, "It just looks cold." She says, "I don't think this is turning to rain" .... heh, good call. I just don't know if these kind of bust can even happen anymore ...although 2005 was not terribly forecast to be fair. But obviously, it too over produced in drama ...what with 110 mph trop. folding p-wave winds straifing the Cape while Metro West was blinded by snow falling at 50 dbz thundesrtorm rate... It was still totally AWEsome! Anyway, as much as we like to make fun, it does seem the bigger gapped busts are getting rarer, because the models may be just good enough. After these.. I've seen 4" an hour probably more than a dozen times in my life. I've seen in it Lake Effect in western Michigan but ..that's technically meso. I think there is a steep probability curve at that mass, perhaps. Like it gets into that realm where excessive outputs are, perhaps counter-intuitively, relying upon such fragile constructs or something that they too often fail to set up and you have to "settle" for 4 -

To be fair ... I am not sure that it is mine, per se. But I get what you meant... I am not sure which came first, my bloviating, or whether reviewed/officiated science on the matter was just happening all along unwittingly to myself - probably the latter. With millions of minds looking, pensively peering over environmental facets these days ...very few novel ideas are really out there. It's more of race to be published first, while half their reader's are all going, "Yeah, we know/knew this 10 years ago... " But the point is, it's saturating content everywhere. Most respectable enthusiasts, to normal climate and Met folk alike are aware. Although personally, I don't know, nor have read any formal "transition season"-attribution studies. Like the fact that snow in October was perhaps a 1::15 year ( Will ? ) return rate prior to 2000.... since then? IF just taking these 21 years, it's like 1:2 That's either a shift in climate...or one heluva repeating fractal in the vagarious noise of climate. K, so - having said all that, re the 2nd bold sentence. The short answer, no - there is no requirement in that sense? +2 is based on a climatology that spans previous decades, prior to the present and/or future climate, which are by all evidentiary empirical accounts and mathematics after those facts, sloped up ... means that we are inherently at risk using past climate to assume anything like a 'balancing' - for one, we don't know where the base-line is in a moving foundation. We have been getting the autumn snow oddities. We have also been getting weird, deep May CAA events too. These prolapse and lapsing cold season phenomenon - I suspect - can be attributed to HC expanding. This expansion then "triggers" velocity soaking in the mid latitudes earlier than normal - and with faster base-line wind velocities in the middle Troposphere, that is going to ( by geo-physics ) materialize coherent R-wave distribution ... This precedes patterns that are capable of delivering cold early, and late, relative to a slow hemisphere. This than has been doing weird aspects to the mid winter months two - DJF. But that's another topic.

Lol, true but...there are other reasons humanity can and do stupidly place official thermometer houses/ob sites where they do - it doesn't have to be airports per se. Frankly, I'm not sure why - anywhere for that matter - these temperatures have to be out around those civility escapes. Obviously more usefulness in climate science.

Yeah to each his/her own... Bottom line is, I have a lot of patience for 40 to 50 drab weather in Autumn than I do not for that kind of weather in April. And in a way ...although I start getting excited for snow as Octobers move on, I also have patience for warmth/Indian summery fare as well, just because we have winter still coming, either way. That's basically it. If we wanna break it down further, ...obviously it's situation-relative. Like, if its 44, gloomy cloudy slate skies on Sunday at 2:14 pm on Nov 13, and the models have an interesting scenario with hints of cold profiles waiting for Half Time scrolling, that 44 almost seems charming - lol... But if it's May 3rd, and green up is clearly 2 weeks late and we're on the verge of chopping down solar max days with it, that may as well be rectal plaque.

That Worcester one there ..that must have been before the 1K move up the ladder. I don't see that altitude doing those dates when we cannot hardly ever get July to do that there. Just guessin'

Curiously ... where did you find these ? heh...

I dunno - I like those nostalgia afternoons though, from Oct 20 to Nov 15 or so... You know, where it's 44 F with sloped tepid sun in between virga blobbed CUs passing near-by, that send spritzers of cold rain drops along with those teeny packing pellets. Not enough to wet the air or Earth, but in the air. And it's accompanying the deodorizing polar air aroma that we come to recognize as that 'smell of snow.' Completing the picture, while doing the particularly loathsome chore called raking, the wood smoke curls around the stacks to add some cinnamon to the air. Baked chicken and mashed taters with gravy .... Or, en route to crew with dudes for b-wings and Patriots games ... In either one of these two settings, knowing you have 3 or 4 months of winter weather phenomenon to switch gears finding inspiration. I don't like that packing pellet days in early May, no LOL. Maybe those autumns are gone forever. After that shit show yesterday, the Pats part of it may not contribute again - haha. But also, I think we are in trouble for those 'transition weeks' anyway. It is hard to steady state the seasonal migration when we have this CC stuff more and more so proving to be a disruption on circulation structures and pattern this and that, when trying to move the hemisphere colder. It seems it's like 70 F or ...advisory snow.

Yup, that NE Mass action came over/down Rt 2 straight down the Mohawk Trail just prior to dawn, and we got popped with I'm guessin' .5" in 15 seconds. LOL, but though rain seldom wakes me up the roar of it this time, did, and sounded disturbingly rumbly heh. Really fast, but drowning rates. Only two flashes. One was typical crawler, but one must have been a positive stroke judging by the acoustics of the report along with it's ability to resonate the structure of the home.

No shit, man - I just saw that 192 hour look. this, is anchored so deeply in every statistical inference method there is it'd need a planetary root canal not to succeed. But it's not just the y-coordinate of the non-hydrostatic height field, as it's rollin' through the OV/ southern Ontario. I mean that's probably only 1 or maybe 2 SD in actual vertical anomaly. It's the 'longitude' of that wave structure/ x-coordinate. It's very massive in that west-east aspect. That thing is like a tsunamis wave out at sea, where the energy is all in the lateral, such that when it hits land it piles up ... and become vertical? Sort of a metaphor for the real surface temperature potential. A more "intangible" aspect: with so much ballast in the 'length' aspect of the larger synoptic wave, that means it is got too much momentum and will likely need to degenerate over longer time. In other words, that's not looking like just a 2 day misty warm sector there. I mean sometimes these dramatic warm signals ... particularly post August 15's, will tend to over balloon ...and then the westerlies come along and dictate them as short duration warm sector intrusions ... etc. But that really looks it has a pretty solid and confident chance to be more than that.

Maybe I'm not searching right but this is actually not so easy to find. Trying to find the 'latest in a calendar year a heat wave took place' ... etc, but it's not apparently a very popular observation -

Except you'll be in the 80s ... but sure. Well okay .. .if your hangin' out with Red Tail hawk aeries up there above 2K elevations ... sure. But this is everyone S-E of the ST L. Seaway bathing in a deep, homogeneously (through the vertical integral) warm anomaly. I bet its positive anomaly from 200 mb all the way down lol.. I also think DPs will be too high to shed temperature that much at night - even this late. Might be interesting to test the seasonal dew ringing, vs the (CC + pattern anomaly)/2. I almost visualize morning's so dew that the soil beneath the feet get real watering and small puddles form in the gutters.

Right now ... Nicholas looks like a classic Category 5 "mimic" on IR. The radar out of CRP ...that's you know, NHC has their methods and agenda and it is what it is, but frankly ... the scary specter of insidious black and pink vomit on IR looks more so like a convective artifact. Only weak indication of real organization on objective radar scans as it seems. I remember back year ago, there was one of those insane -100C top canopies sustaining itself over the Caribbean, and NHC had it all way to to 65 mph TS ... the works. RECON finally gets in there ... TD with a weakly closed/vaguely discerned west wind where the southern aspect of the cyclone should be at best. I think they kept the TS status but reduced it to 45 mph based on RECON ... something like all of 2 uncontaminated pixels to on the NE side trying to be that much... Meanwhile the sat IR kept blazin' away like we were witnessing a Chicxulub impact. I remember the next day, that menacing look faded and sure enough, a weak lvl curl popped out and I don't think that thing ever went onto anything really. That's all something else though. TX may be in for a really bad flood ordeal, either way.

I noticed as we got closer to today thru tomorrow, the models had to back off on the mean frontal position through our region. In fact, synoptically .. the high pressure through eastern Ontario evolved less massive, while 850mb has arrived less depressed S. Was +9, three days ago... with attending total air mass quality looking more 'across the bow' back whence. Now we set at +15 to +12, looking SW to NE thru the area, the air is tinted in DP...the wind is too light to signal much advection, and the clamor of summer insects are still sawin' away at it out there. Ha ha. Nothing Earth shattering in noting that tedium but ... it's 'correction vectoring' ftw. Recognizing the 'synoptic footprint' as still unchanged during any transient events that are nested within some larger framework, is useful. Models, particularly beyond short ranges, will often if not typically attempt to sell scenarios that over-compensate. Then, the preexisting 'tendencies' manifest and correct x-y-z modeled phenomenon back toward the predominating mean. This is a warm pattern... one that is before the warm one folks are even talking about toward the week's end. It's hard to know/boundary that, versus today at this point. Maybe it's a warm pattern that 'gets even warmer', but the synoptic correction we just saw leading today in the Euro spanning the last week is pretty classic footprint correcting behavior. The sun is weaker and weakening... but we are still on the warm side of the Equinox by a pube. Here's the thing, a month ago that would be a slam dunk heat wave out there D6 to 9. At knee jerk take, I don't know if we can do more than the mid 80s right now. However, ..thinking back, we did an 84 F afternoon in mid February (2016 I think it was...) ... actually I think several Febs have had some eerie warmth. But, that happened some 5 weeks prior to the Equinox, or on the 'cold' side. So, the dimming sun-angle can be overplayed too. I think if we get a bona fide dose of 18.5C at 850 with 'thermal momentum' (leading warm pattern of sufficient density/time), ... What is the latest heat wave on record for N of say NYC ? I'm sure it cheated to so with three day 89.45 at some stretch or the other in the last 250 years ... but either way the return rate's gotta be pretty low on that. Subjective ( imho ...) the back of summer is broken, but this is a CC September incarnate and that larger guiding factor is skewing/smearing the effect toward less distinction.

... The Harpseals are a furiously flippering their smart phones for the latest model guidance... haha

The GEF-based PNA is in free-fall, while the NAO climbs and holds static in a positive .25 to 1 SD mode ... essentially for the next 2 straight weeks. The convergence of those and doing so at length, are not exactly constructing 'chilly' thoughts. Then, the operational guidance, et al, over night look historic now with heights everywhere, south of 50. Some distant whispers of seasonal change might be more evidenced in the EPS mean. Persistently wants a strengthening polar branch ... mushing it snuggily over top said heights running along southern Canada in the ext..

Nick is born ... seemed to go directly to TS status...

It's funny ... we spend decades of man-brain power, and probably billions in tech evolution, in order to sample and eventually predict the environment. Spend 10 minutes over a cup of coffee doubting what it tells us as over-cooked conceited hams - lol. I've done it too... Sometimes I admit that I just don't like the look of x-y-z handling in a-b-c model run. 'That's not gonna do that.' 'What's this f'n model doing out of nowhere with this' Pick the tossing internal monologue... Thing is, sometimes .. yeah, we are right to doubt. Certainly, pushing standard deviations should strain believability and force some thought. Heh. But I have noticed just like 2007, .. "Ida" ... just because the specter of model cinema can't be so, is no M.O.

This very similar repulse and response mode seemed to take place prior to the Dec 2008 event. Off-topic ... but the NAM began flagging -2.5 C at the 950 mb ( like right over tree top level) along the spine of the lower Monads ( which by geographic extension includes the Worcester Hills, btw ), WHILE the grid was also QPF'ing 3.5" of rain. It seemed that devastating ice storm was outright f'ing there all along. I'm not saying no one took it seriously - the general threat for aspect. No. There were warnings ... But I'm pretty sure the accretion/warning was .5 to .75" of ice rhyming, basically low-balling the shit glue out of what took place. And it was jaw dropping ... pretty much exactly what the NAM said: less than freezing + heavy rain.

I really wish it were not just fantasy that there were an econ incentive that argues never allowing Tweets be allowed/posted. But, unfortunately... that opposite must be the reality. Can't these narcissists and their followers PLEASE keep their morning shit thoughts to themselves -

It’s interesting this thing I’ve noticed about the 18z cycles (haven’t checked the 06z) of that model. it’s like it goes out if it’s way to shave standard deviations off everything … everywhere. And very consistent behavior. It strikes me as a systemic error when it’s that dependable, but also then washing the whole-scale handling weaker is less than entirely believable … maybe assimilation

You eat more water and like it.
