Typhoon Tip

Ah... there's multiple reasons why this thing's behaving the way it is in the guidance - not one silver bullet. Having a S/W cresting the western ridge, doing so at a fast rate of speed is giving this thing on the east coast an non-linear negative interference ... ( transitive destructive - ). Some of this is going on, but not the whole story. What Brian was discussing certainly contributes, too. Then there's the convection. It occurs to me that there is an anomalously intense B-C axis in that vicinity down there. There really has to be, when there's been days of -3 SD air mass near-by a hotter than normal SW Atlantic OHE for the past 10 years. Ha. I mean Jesus... the convective potential is so extreme - if that metric were kept track of, it's probably historically volatile. Really, the expression "too much of a good thing" keeps hittin' at me. You can't exceed a threshold of potential in convection. Have you ever heard of the "K Index"? It's number that describes the general convective response once trigger has taken place. For example... in the Plains, a low K index with a very high CAPE and CIN collapse produces low counts of CB but huge super cells. If the K Index is high... the whole region erupts all at once and kills the organized super cells... etc. Something similar - this is where it's supposition but the more I look at this I suspect it to be so ... - is taking place where there is a high potential for convective response, with no inhibition... The whole region is igniting pretty far ahead of the trough... and there is so much potential due to the extremes of air mass over hot water ( relatively speaking) that the convective processing is blowing a hole in the troposphere and creating a new closed 500 surface out ahead of the real tough. That's why we are seeing this shit.. If you follow this 84 hour NAM chart back in time, you can see how the convection is evolving it's own S/W presence and then taking over... It's like a Miller B at 500 mb level.

Man... I don't know where y'all find the patience to carry on with this one.. If this was a gf I'd-a done told the bitch to get the fuck out two days ago.

yet another way to metaphor it, we got *!@#ed in the ass

I never had a problem with this winter ..even before this last bigger snow producer. I just figured it for over-achieving on cold alone- I realize the demarcation is based upon snow fall, but that's endemic to these individuals and collective psychology amid this very niche' social media. We had early blocking ... we had snow threats. Some minor ones panned out. But a bigger event eventually transpiring was a parlay when we had/have a cold biased winter pattern persisting the way we did. Notice also ...we didn't get a bigger deal event until after the N. Pacific corruptive variant of the -WPO plaguing Dec was finally fully vanquished. That was a toxic relationship with that giant narcissistic block, LOL. Anyway, we got back to episodic -EPO bursts and allowed the Pacific to undercut for a coffee break and we get a STJ drive snow bomb out of it. Anyway, even if we didn't get this 15 to 20 incher, we probably would have ended up near normal by the end off 2-3" buck shot adding up over the long haul. So there... normal snow in a cold winter. The problem is... that psychology ^ ... people tend to judge the winters based on weather that they get that psychology masturbated or not. So that's really a different discussion entirely..

I wonder if this can be ironed out if that relays weaker up there ... LOL, frankly I've grown weary and tired of even looking at this motherfucker

I actually agree with this sentiment ...wrt to just this 12z run, sure - The system's close 531 dm actually encases the whole region with some E component at that 500 mb initiated. The QPF paint on the actual surface chart looks dubiously broken apart. This is a very large system. It's possible in fact probable that the there'll be an extended quasi CCB arc out farther than the typical size one may be used to seeing. I mean I'm not trying to gaslight anyone into thinking but this arc could be more formed than what we are seeing here - if having the visual example helps ...

Mathematically ... the speed of the flow is absolutely a part and crucial part at that, in the Navier-Stokes momentum of fluid system equations, to which these models are physically responsible for. Propagating a wave through that medium is effected - There may also be other factors involved; I'll just add that I've seen 500 mb progression of Feb 5 1978, and the block decaying was observed as collapsing S - it was in fact what triggers the N/stream to fall S/ subsume scenario. But maybe I don't know what you mean?

I don't know what everyone's written overnight but this is gonna have to be a positive bust at this point. Otherwise it's a saga about a signal verifying, a storm resulting, and we (winter enthusiasts) get porked. Done deal. It just is what it is... It's still odd that the whole bundle/wave space is taking such a parabolic motion and won't obey ( apparently) convention, but .. these things don't always fit into the text book in this business. Anomalies, relative to (as in within) ongoing anomalies, due also happen. There's a logic to it ..it may need reanalysis and whatever to suss that out but ... I would still strongly suggest that the background speed soaked flow is playing around with and stressing standard models into behaving in odd ways.

I doubt that low pressure bouncy ball mess off the southeast coast is legit with the NAM

Looks like switching from positive PNAP to more of an overrunning risk spectrum

Funny at the gym I was considering the Boxing Day Storm and how 48 hrs prior that system had been all but entirely smashed SE off the charts… I think it might have been the NAM that made significant surge from the dead … Of course doubts were going on in here like a whiteout Then one by one … 300 mi yanks out of the grave … every cycle going forward off all guidance. The whole thing waited until there was literally zero hope. Ha ha ha ha Anyway, wasn’t the boxing day pretty high in the list of analogs the other day? It would be kind of fitting if this one came back, although doing it from day four is probably not quite the same scenario

So am I to understand from this that the entire euro system shifted west…like en masse?

This had a hook and latter vibe to it early on too… Sort of got lost, but we may have to go back through that phase of stuff before this ultimately becomes a real deal. Looking ladder storms do happen though.

Funny yeah, that’s where the low really should be… I think some of these recent upgrades in the models at all our hypersensitive to convection maybe. Just a thought. Coupling that with a speed flow contaminated atmosphere that’s never gonna integrate well with a low that’s trying to close off and structure itself vertically.

Scott's just tuggin' on minion chode hairs with that. We're in the solar minimum for another 2 weeks. The sharding back of snow banks will begin in earnest after the 8th ..10th. Having said that, there was day light at 5:30 pm today ...I noticed this as I was leaving the gym. That was pitch dark just last week at that same time. We're on the slope - can't be denied. I also thought the sun coming through the S windows felt warmer on the face. It's just a fact of celestial mechanics and life.
