Typhoon Tip

Euro was teasing in the 00z release, too ... but at finite scales. Heh, where only the kind of digging of the desperately damned would reveal. But the Monday system's rain snow line is like 23.4 miles SE of previous runs... It's basically Canon CT to MHT NH... anywhere above that line net gains from that. Unfortunately... anywhere SE is cat pawing madness, net losing what they don't have, where it must feel like god's been raising the dead just to tax them some more. Then the 26th ...has the better front-side air mass like we've been noting, and holds just enough to net gain Rt 2.. Like it snows with gradually diminishing visibility, then right about the moment it crosses the 2 or even 3"/hr rate, pings and pillows take over then it's light rain... BUT, the moral victory is that this system is moving quite fast, so just about the time all that transition happens ( slower to take place from S-N of course... ur right, CNE does well on the 26th), the max uvm passes off and it's misting. That's what that looks like in the 00z evolution to me. Pike might even start as snow and pingers... in fact I think the pretty coloring book versions of the QPF shows that - but transitions to fast to net+ .. One other thing.... these events have been ( as I suspected ...) deamplifying as they've relayed from the outer mid range into mid ...etc. Monday's wave is in fact barely below 1000 mb leaving Cape May NJ shores, where it was once a d-drippin' 978 or whatever that was last earlier in the week. But this is probably why the rain snow line ( in the Euro for ex) is situating the way it did...it's sort of a swap - a flatter system doesn't overwhelm a tenuous polar air mass so readily... They tend to ride along what thermal wall there is, albeit weak. But more so for the 26th, I'm noticing the 500 mb/ wholesale mid troposphere wave signature of the this latter event is in the process of morphing in the runs. It's possible the 26th begins to diverge from a cohesive cyclone model ...devolving into something else... The primary low in the Euro, is over BUF at 1am Thursday at a stunning depth of 998 mb for a reason.. Looks like the whole event is purely a WAA thrust -driven, and losing the cyclone presentation. We may may moral victory that event, just by virtue of it turning into something else entirely. We wouldn't have to suffer the indignity of being raised from the dead yet again on that one. By the way...not sure anyone is paying attention but Canada is loading up with some serious arctic syrup beyond about D7..8 in the GGEM/Euro. 574 closed hydrostat down to mid Ontario is no f'n joke! Pattern must've changed, huh -

00z NAM trying desperately to get to an isothermal scenario. Has 0C sfc to 800 mb over Logan at 60 hrs yet keeps that all rain. In the words of count Rugen, “That must be the worst thing I’ve ever heard - how marvelous “

4.5” here 10.5” in the season

It probably would start as snow everywhere or at least a mix with that antecedent air mass… But how long that lasts would be briefest at the coast and longer in the interior. I don’t think that’s going to Miller B saved the day …there’s just too much mechanics turning N too early inland. That said a residual secondary low that’s having trouble getting going might prolong some ice for awhile from the deep interior southern New England and points north - just an option …unless the deep layer trough en masse evolves further east then we’ll talk about more secondary commitment

I was talking about Monday... but, yeah... they're kinda twin events -

I'm not sure the track is as important with Monday ... there is a defined lack of cold air.. The track is already doable. In fact, the GEFs ensemble mean was tightly cluster along an ideal track, actually. RAIN sometimes there's just a lack of cold air. Next - That's what this looks like. I keep reading NWS and posts on social media, discussing the track like it is the main sensitivity to where the snow axis is... WRONG there some...sure. But if it's 37/34 at Orange Massachusetts and nothing hanging around in CNE to help out... it won't matter where the 'flatter solutions' track.

Posted earlier ...they're having comms problems - they released a statement this morning.

what does that mean ... RUT is interior "New England" oh never mind - this was yesterday... haha

Fwiw, the 12z GEFs members are tightly clustered with a track SE of the operational, and with a colder profile for Monday. Looks like the 0C 850 mb isotherm collapses SE between 6 and 12z ..ending up PVD-BOS, as the system makes closest pass

As of the lull this morning .. 2" on the dot here. That makes my seasonal total very close to 9" We'll see how we stack during the day. Right now, steady light snow has recommenced. 32 F

Euro suggested the same thing the NAM is over it's last two cycles, as well. Both are trying sting the CCB, collapsing it back through the region later Monday.. It's likely going to be over QPF'ed if that happens.. but, I just thought it was interesting that they are attempting to do that. Euro version was the more impressive, too.

You know ... re the pattern change. I've been watching this aspect that last couple few days in the ensembles ( cross-guidance). It's possible some of the smoldering consternation is also self-afflicted. Why/what I mean by that is, we've been perhaps rushing this no sooner than it was sniffed out as even plausible some 2 weeks ago. That is/was not helping matters. We are/were less likely to manifest any system prior to the 27th as being winter enthusiast inspiring... That 26th system appears to really be an '850 mb inflection' event. Beyond which ...the span of the 40th to 60th latitudes, from B.C. to NS, descends en masse to below normal/negative anomalies. Prior to that, the pattern may be augmenting ( or not...) in the 500 mb isohypsotic layout over the local hemisphere, and in a lot of ways that can be pointed out as being the case - suggesting the d(pattern) is actually taking place... But, I think as far as both sensible/experienced weather, and... being able to manifest systems that are more in the 'like'/d-drip potency ( LOL ...) ...seriously tho, we were not really favorable prior to the 27th, particularly over the eastern continent. Around that date for this flood and mass field significant and deeper change has been very consistent... Prior to this ~27th critical inflection timing ...we've largely been manifesting events in layouts more consistent with this... This latter thermal layout is more apt to present challenges for realizing wintry appeals. We can't walk through a landfill and be surprised that it stinks. The cards are stacked against us... Pick a metaphor. One aspect I am also noticing is that out there around the 30th... there is a bulge of 850 mb temperatures ( more aggressive in the EPS ...which makes sense for it having a meridian bias in that range), where/whence the neutral line gets to about ORD-BOS before collapsing SE. There may be significant event in there. By that time, the cold is established, then that bulge transiently passes through...that's an opportunity. I did take a peek at the individual members of the GEFs and there are several members (below any consensus, still ) that are interesting. But, otherwise, ... that looks like this winter bottoms out in the first handful of days of February - we'll see if the period suffers model "magnification correction" as it nears.

I dunno... that 06z GFS was too close to an isothermal hammer over ORH to dismiss Monday's system. The heavier snow axis is likely ~ Capital district of easter NY up through the lower Greens/Whites, but I'd put a wild-card band between that axis and ~ ORH and wait it out through the weekend runs. That's like a single tick from being 6" of dense paste. Threading the needle 101

I find it personally interesting that the NAM is like that considering it typically has a Northwest bias at that time range… Really anything over 48 hours yet it’s the most southeast solution

00z NAM looked like 3” over metro east

We flipped back to rain 2 hrs ago. Once in while there’s a ping or two against the sills … looks like the bigger drops are cat pawing too. I noticed on P-type rad it’s snowing on either side Methuen right now which I find to be rather remarkable.

Ha. At present moment … ptype rad indicates it is snowing on either side of Methuen … it’s really quite remarkable

When was the last time the NAM scored a coup - gosh...I think back to 2005 really. Not sure I recall since -

Just flipped to gritty slush snow here about 20 min ago. Very quickly the roads turned gray and turning corners tries to tale a bit... It'll get slick in a hurry folks. 33. Some kind of S-/R- mixture at the exact moment though.

Wtf i’m looking at the synoptic charts and I’m not sure I see how it’s going to snow anywhere close to that much south east of about an Albany to Fryeburg Maine line The events depicted here look like they’re moving too fast with shredded out ptypes and amounts

Just need that girl, the real reason I even came to this party of dead-beats ... to grab my attention before I'm out of reach and pull me back in. Like that end seen in Something About Marry ..ha

I was almost speaking to the straw man ... in the off chance that there are those not clear on the concept LOL I'm half out the door - admittedly ... if prematurely.

'now cast' appearance on the entry into this thing ... the snow appears a little more aggressive on various p-type outfittted rad presentations compared to modeling. just sayn' not sure if an obs and amt thread is worth it for this - but ... Looking around ... WPC's current sfc synopsis shows at 16:30 there's a weak cold front slicing through the region. It's hard to detect this in sfc ob/wind profiles, and the DPs are also not very representative, but it is what it is. This situation being very sensy ...it 'might' matter? Right now up and down rt Poop we are generally 37/28 ... Rad with ptype suggests very quickly going from nothing to some sort of light to moderate fall rates, whether IP contaminated snow column or snow. But that's evidence along a line roughly SYR-HFD

I prefer to just maintain an objective vigil … But I suppose as an approach to this engagement either method is probably going to end up in the same mentality - semantics. Having said that… gosh, not a good series of runs last night regarding any of these possibilities we’ve been tracking over the next 10 days – essentially in one run the consensus depiction wiped out multiple cycles of trend towards better solutions for winter enthusiast. Such is life in the dreaded needle threader circumstance… which naturally means that there’s some probability they’ll come back obviously It may snow in those systems. But obviously all can see it’s way out towards the capital District of eastern New York up into northern New England… That’s just the winter we’re having thus far, even if it hasn’t performed particularly well N-W, either. It seems the model runs last night just clicked back into the trend of the season… Mm part of keeping an open mind is being open to the possibility that nothing will happen – just sayn’. You know if I have to be blunt even the pattern change itself more so looks like it’s got short legs on it… So others have intimated this over the last couple of days. I’m not sure I disagree. The long awaited new paradigm may limp into the first week of February after which I don’t know. Hm if we really do slip into a negative PNA sans blocking there’s nothing about the last 10 years of climate that suggest we won’t soar into the 70s for another historic run of it next month. We’ll see if an extension corrects in, going forward
