Typhoon Tip

sneaky brutal N of the Pike ... we have 86 to 89 at all home stations networked into Wunder that are within 5 clicks of mi casa and they all have DPs 75 to 79F ! it's not a trivial HI, no -

One of those nights in the urban centers I wonder

Good heavens! Are y'all actually still trying to win -

They may be on the verge of significantly adjusting that threat assessment to a 'nah, never mind' status - Looks like the opus in summer fake-outs by the models just made everyone a fool - EPS punching the Pac jet across the N-Tier like that will ablate the ridge pancake meaningless with strafing MCS that probably even end up turning right before the get here. We get a nothing ... for ever - It's called the wah wah waahhhhhh pattern for summer enthusiast. Otherwise known as 'New England'

yeah...no dependability with that heat signal - hard to say if that's just typical day 7+ follies, though obviously there is some of that in that sort of time range... but this has been the seasonal tempo this year, to consummately put up those big warm signals and then watch the models cleverly dismantle them... watch us end up with a shot across the bow autumnal trough - in july no less..hahaha. kidding but it seems continentally there is too much heat forcing out around 110 west to expect ridging east ...something like that... not surprised the Euro backed away from the bd though...it's done that, too, whenever the residual trough tries to move/fill NE and smear out it sees a 12 hour wind of mass in GOM and can't resist the geophysical feed-back in creating those. thing is, ...that's how they happen...so it's hard to 2nd guess - the 00z probably ridge bulges back some .. who knows how much. but we've been sloshing at large scales 00z's being warmer, for several days now.

I imagine there is some problems with the guidance et al because of the system's poorly organized and pallid structure - If/when that gets better vertically oriented and presentable in terms of physical momentum in the grids ...other than a llv swirl that occasionally farts out an anvil ...there might be more consistency. The other aspect is, the variances et al are not that huge anyway - but the sensitivity is necessarily high because a band'll dump 3" and nada two towns away...

interesting parsing effort for that statement ... buut, the cultural relativity from ethos to ethos in this country is a funny comparison exercise. I lived from my unfortunate exposure to this world through 14 years of age in the Battle Creek -Kalamazoo, mid-way Burger King rest-stop between Chicago and Detroit's marvelous blight trades. Back whence, southern lower Michigan pathos was achieved by exited failed mid 20th Century industrial islets amid a sea of otherwise cow-shit and corn-stalks as far as the eye could see. It's changed ... ing, in the last 20 years... with farm-lands recovered and converted into single-story mall complexes and a lot of triglyceride restaurants that skirt college arty wannabes ...but at least they're trying. Back in the day... you bolted your car with a double fractal encryption encoded locking systems that God couldn't get into if it meant saving the Cosmos if you dared run into the corner store for a bottle of "pop" - as they called sodas there. Houses? Forget it... you posted Ninjas with light sabers. My family moved to Rockport Massachusetts early in the summer of '84. No one locked anything. I thought that was the weirdest thing I'd ever heard of... At a friend's house, we leave, "Aren't you gonna lock the door?" furled confusion in the face. He looks at me like I just arrived from planet Zarcon and so it's understandable that I don't know the ways of the human species, "Noooo ...why would anyone do that?"

...typically you will find them in a 69.8/49 F environmentally controlled setting

88 to 90 / 70 to 75 here in interior SNE is enough - heat adv criteria ...probably could/shoulda been expanded but whatever .. .in "or around" definition should suffice. but wow, ... ASOS DPs are 70 to 75 ... who paid 'em off to admit that -

days are long ... I suppose it's imaginatively possible we could transition into a quasi, albeit weak TC sounding through dawn...out the ass end by noon... through a transient mid level stranded CIN plume dull afternoon...that moves off and 'unlids' for a late ... yeah ... good luck populating grids at NWS heh...

nah... what's likely to happen is a latent heat conversion, transient beta-synoptic scaled plume of mid level heat gets abandoned when the vertical structure wanes and ceases and leaves it behind, and that'll effectively CIN the asshole shut like a bull's ass at fly time... 77 DP and 5,000 CAPE choked closed for business.... Save for that one cell over Mt Greylock that rains 5.7" in 2 hours and doesn't move and takes out a campsite of Boy scouts -

I don't know .. that hi resolution visible looping is pretty fantastically convincing to me... this is an exposed center devoid of anything ...with a displaced wall of squally showers well to the E of best fix... RECON will definitely bias toward that convection as part of their "near land PR modis operendi" but in reality, this Meterologist needs to see a glaciated cu tower at all near that exposed center - and...preferably have the plume not moving across the low-level cyclonic axis of rotation. So yeah...add shear to the limiting factors... Also, I put the 12z on 36 hours over at TT and clicked prev 5 times and across all those cycles, other than very minor insignificant variances...the solutions are identical - GFS operational... So, it may be wrong, but I don't see the model having continuity issues in a vacuum ...

yeah... we had two course in tropical up at UML as per curr.

mm, I'm not sure the type of torsional mechanics that twist columns in land falling/land interacting TCs is the same as that which is supplied by the typical shearing structures that you're using there, though. With TCs, what happens is the flow moves from a relative low impeded region, over land where there is an abrupt increase in frictional induced boundary-layer drag; the air must by conservation bend inwards toward lower pressure more so in the 0-3km layer, which instantiates positive shear ... more sub-geostrophic inward, causing a hooked updrafts in the lower 3-km, while the overriding air in the unimpeded 700 mb level is defaulted to increasing bulk shear; a different aspect than suspending a parcel through a vertical column where there's potential vorticity due to bulk shear aspects, synoptically. That's not likely to be modeled well because by convention/state of tech ...models don't resolve that lower layer very well

I'm also wondering if this local time span ...the last three days worth, of model cycles is 'thermally sloshing' ... I've just noticed that the 00z runs look a little hotter and less subtly muted than the 12z cycles, and the difference is that either grid initialization is at the other end of the diurnal cycle

Valleys ? nah... that's a brain scan/neuro-tapestry of Gaia ...and is she pissed!

Could also be a scenario where the modeling et al just rushed it ... which I hate. I've actually seen summers(winters) that persistently put up delicious menu patterns in the extended, and then it finally happens in the first week of September ...or, the last week of March...as some jipped version as though it was a bate-switch the whole season at hand...ahahaha. The thing finally gives you a taste of what it was lying about, but still smacks your face by doing it when heat or cold is seasonally muted for being so lagged -

Yup... I was musing with PF the other night how invariably ...this spring into early summer ( so far ..) has been an exercise in futility getting 'biggish heat' looks inside D6. In fact, it has not happened yet successfully - speaking to SNE... Yet the modeling in that time frame would have driven humanity to a special consortium summit for the heads of climate impact regarding the death of civility as we know it... Brian and I were speculating that there's something in the back ground physics that's opening open up/exposed by the loss of nearer term offsets that do seem to get smoothed out -either by model convention/design, or perhaps time... Basically, either removes the nearer term offsets and some underpinning signal expands the ridging... like canvased tendency underneath all else That said, we did see the Euro do this on a D7/8 chart last week with a BD and it disappeared within a cycle or two ...so there is some precedence, within that general failed framework, to still oversell BDs by the Euro... It's really like layered errors: too hot of a synopsis in general, is offset by a fictitious BD... when neither happens in lieu of the pedestrian reality. I can see why the Euro is BD manufacturing though ...the trough in the nearer term ( D4 and 5 ..) residually limps and fills its way into the Maritimes, but has just enough mechanical power to NVA some mass build-up over the region...then, geophysical biases kick in and the model can't resist. Here's the the thing... the model(s) et al are subtly introducing flies in the pure hot ointment comparing yesterday's purity, anyway. And that's usually how the shirking starts... We could abolish the BD and still end up pedestrian and forgettable for the usual erosion/corrections anyway...

Today is open sky dead wind stifle ... it's 83/74 at 9am here ... with leafs on trees still like solidified in amber. You can hear the sun's unadulterated insolations ...sounds a bit like microwaving sunday's roast.

Seeing as you were begging for additional insights ... -- the 'swhirl' will comes up the coast more intense than expected. invariably, the models will not handle the physics and get sort of mottled or confused with the land being nearby and improperly fusing drier air source they'll fumble around and phase smear it between two cyclone types... which then assesses the system larger and less coherently intenser core-ward. Meanwhile, the swirl crosses a developmental threshold that the models and humans never see coming...whatever that is - and it's relative to the super synoptic metrical layout when/where/strength that happens. Once that happens, it leaps to 70 mph and they hurricane warnings to Long Island when no one around land is even seeing winds gusting over 45 mph... -- or, weaker, ...because it's proximity to land and colder water N of the Del Marva will mean the models and interpreters improperly fuse these cooler sources and thus, fumble around and smear it between two cyclone types while biasing too strong due to the don't-ask-don't-tell over-sell PR tactic that TPC employs but doesn't admit to M.O. whenever Seagulls fly within 500 miles of any coast... -- the NAM typically has maintained a NW bias with western Atlantic cyclones. I dunno know if that's true with tropical/barotropic physically powered phenomenon, or, if it is still true.. but, that was the case through the 2010s

Hey Bob... ...let me know when y'all think it is worth it and I'll pull that post from earlier and create a thread for that heat - I mean ...perhaps too early today. 12z operational GFS went alarming... It's alarming because this run does not very readily transport thermal ridging polarward as a base-line bias, yet it's D9 overcomes. is literally dangerous from Chicago to Boston, with 22 to 25C 850 mb in rare trajectory for multiple diurnal cycles... and unless there is some impossible to determine MCS modulators that's going to be a delicious soup of pandemic, dangerously high heat indices and brain amoeba tick bites... In fact, we could start that thread and put a bold disclaimer that it is experimental and should not be deemed a forecast at this time but something watch in future guidance...

Operational GFS slightly more robust with D8 heights ... I'm surprised this particular model manages to get to D9 without carving a NW flow and grinding heights backward on this run... This model is seemingly parameterized to circular sander ridges into buttes... but, this is the 4th consecutive run where if anything, that is less evident. Hmm... By day 10 we see that beginning but... that far out the model's likely losing the foreground signal in low of the base-line perennial circulation that doesn't want 594 height isohypses hanging around from BUF to BOS to put it nicely.... That's a definite and bono fide heat wave there, D7 entry into D10 ... by hydrostatic scaffolding alone...

I'm actually more concerned/excited for the Mohawk Trail/Rt Poop corridor down in N. Mass/S. VT and NH because typically around here, we right turn and start pac-manning cells toward the richer CAPE early..... But this is also got that mountain lift thing up that way too...so synoptic metrics combining might offset that effect too -

yeah it was about 4 minutes this time ... phew... lol.. kidding. Morning coffee

For now...agreed... I'd even go 19 C as a base-line corrective assumption and think 94s.... Just seasonal trends, as we mused rightfully so yesterday - I'm a big fan of trend like that because they are really an echo of the background environmental mechanism - eventually, the teleconnections et al will dictate because energy and mass is conserving in every direction...blah blah blah. The GEFs agree with the EPS in the 500 mb hydrostatic layout within an acceptable margin of error, and both are nearing or at historic plausibility ... hmmm. Here's the thing: It's the first time that has happened this year.... so, that could be a philosophical argument to offset said trends -we'll have to see. But both/blend offer a margin of error that would fit big hypsometric/scalar 850 mb numbers inside of those hydrostatic heights - ... Course, a cumulus butterfly notwithstanding... The GEFs modulates by D10 into a look where probably it has a couple members tipping NW flow... going toward said consistent/seasonal agreement. That may introduce BD contensions and longevity ...probably start sending quasi-dry-line non-cold fronts that skrew us out of big numbers without actually being physical recognizable fronts... haha... you know how that works. Meanwhile, the Euro is ratcheting up an even hotter D11 or 12 extrapolation with 25+C 850s west of ORD ready and completely able to dragon fart right on in here ... Yeah, that 1911 comparison...interesting. It's too bad we haven't got a better re-analysis source work for that?? I mean the NCEP library is sketchy earlier than the 1950s...
