Typhoon Tip

It's doing something similar to the GGEM's 12z solution ...which is to split open the event into two distinct phases... The first is an intense isentropic lift event, with perhaps 6-9 hours for a band of impressive QPF to move through, ...transitioning from snow to rain as it goes. Then it's ENE gales into the coast and elevations inland, with mist everywhere, while the low deepens east of Jersey with the capture, cut-off drifting E from there. At that point, there's modest dynamic support of cooling and CCB cat-paw band might end with accumulating snow. Snow-rain-snow away from the coast in total, but there's two distinct pulses of QPF. I'm not sure the models are handing the slow movement of the atmosphere ( can't believe I'm saying that since 2010!!) ...but much in the same way they screw things up when the flow is fast. In this case...there doesn't appear to be any reason to eject the isentropic engine like it's doing there around 180 hour and running up the Maine coast like that. Lows don't typical just puke their guts and turn inside out like that.

You’re setting sights on next year like this year is already over lol. I just posted though it does feel more springlike out there like we’re stuck in some kind of limbo maybe an extended autumn but if it goes on much longer whence the sun angle starts coming back, it really will start transitioning into an early spring. … we simply cannot sustain winter without cold air duh. But… I’m just old enough and have experience just enough in this Kocamemi game to not throw in the towel on Jan 6 – no way. I’m speaking speculatively if we divorce from a winter hemisphere like this … we can’t add sun and expect aspects to break in favor of winter enthusiasts.

I choose not to bring it up in the court of the lord of the flies.

Climate change … La Niña … or both or just bad luck aside … there’s an inescapable sensation like your looking at model runs, and actual daily weathers, as though it’s circa March 13th out there

It’s trended bigger more powerful feature overall but it still looks like it’s trying to close off too early and it’s dubious whether there’s any northern Stream involvement in this thing… But I wouldn’t focus on those details there’s definitely a trend there across all 12z guidance

At the moment it’s snowing somewhere between moderate and heavy with uniform moderate aggregates size. But 1/3 mile visibility accumulation more uniform on all surfaces.

Well we’ve managed to put together a couple solid hrs of light moderate snow after flip-flopping for a couple hours this morning. The snow is accumulating unevenly even on the ground/non-paved areas. It’s very spring like it’s like a snow in early April where it accumulates in clumps with bear areas in between. Although just in the last half hour it seems like it’s trying to get more uniform

Well regardless of ptype… The GEF signal trended toward the typology for powerful coastal storms. For 180 -219 hrs? This 12z cluster’s about as coherent for climo Nor’easters as can be … unfortunately that can be rain or snow but like I said… ptype aside. The op Canadian is actually a leading entropic lift event… and then when the storm winds up it actually doesn’t even have a CCB on land

What the MJO is doing right now has nothing to do with whatever’s happening 12th-16th. That’s A B, there are other factors far more powerful in dictating the mid latitude hemisphere for temperature distribution. The MJO’ is not one of those. C, the MJO “might” contribute… Or assist in modulating the pattern out in time – and there is absolutely a lag correlation. But it does not drive the pattern. Frankly it’s a little bit odd that this MJO wave is modeled to do what it’s doing in the first place, given to the antecedent an ongoing climate footprint But, climate like rules are certainly meant to be broken from time to time… And I can’t think of a better time than during climate change for that to occur - as a bit of snark humor lol MJO either constructively interferes or destructively interferes… And depending on which determines how much a given wave’s modulation can actually occur. The hemispheres might be receptive (constructive) with the MJO in phase 8 – 1 -2, just based on the uncouple La Niña state of the Pacific - which is not only looking more Nino like, it’s doing so rather violently… Which is a whole nother complex conjecture. But if so it would be later than next week

No overnight… that little critter for the 9th did come back in the models. This is no declaration as to it success… but there is a presentation there. … a minor ordeal that favors southern zone as it were.

Looks like that will have to happen in order for this to get anywhere close to a 2 to 3 inch accumulation… Just looking at the behavior of this so far, as other people have noted, very intensity related. When that band went through we did flip over and wasn’t falling heavy or anything but it definitely was convincing aggregates. As soon as the radar showed that band attenuate we’re right back to the light sleet and light rain routine. We’ll have to see if the meso models were on this or full of shit

Looked like it flipped more convincingly about 20 minutes ago but it’s since just done the same routine …having trouble committing

Despite the radar imagery we’ve gone back to cat paws and light rain here maybe the occasional bigger white streaks by

It is now… When we first transition it was kind of having trouble but now it looks like a Sno globe type snow …big aggregates. there’s no more sleet anymore -it’s either small aggregate fragments or bigger cotton balls. mesmerizing actually. The comparison to 1997 December 23 is not actually quite accurate though by the way - I’ve heard you reference that a couple of times the last day or so. December 23, 1997 was very cold that was the bigger contributing aspect to the model bust/storm result Then the QPF which was eye-popping enough. It started snowing it was 20° and it finished snowing at 27. and those were small uniform snow falling at choke rates. I mean there was no contention no mixing and it was way vastly more intense.

Having trouble staying snow. It’s going back-and-forth between uniform snow and then a sleet/ large aggregate mix

Transitioned to snow 1/2 hr ago 32.5

NAM seems to hold

This is some putrid quality tucking. The flags started pointing S here early this morning at 6:15 at 39 deg. 13 hrs later it’s 34.5. Flags still pointing. Chimney smoke’s rollin S. I can’t help but wonder if 20 years ago we’d be 29 by now

Ugly solution tho...

Bit more N-stream involvement this run...

965 mb 20 mi SE of ACK

It’s a bit rare for the same hemispheric space to wind up two monsters in such spacial-temporal contention like that, though. Takes a lot of mechanical power and that’s usually found around index disruption events. We still don’t have this latter aspect involved in the 12-16th period of interest, either. Ensemble behavior should be more heavily reliant .. Will be interesting to see what emerges out of future guidance - for analysis … not d-drip codependency issues. Lol. J/k

I thought the euro did look a little more heftier than its previous cycle on this - no? 12 Z yesterday was a bit more scant than 0Z etc. but I didn’t look at the 06Z overnight

Wouldn’t surprise me if a clap of thunder is heard. Little critters

It’s not a bad place to be… At this range you have something on the maps and that’s it – you don’t need anything else. You can’t ask for anything else. Or you can ask but you’re never going to get it As far as what the GFS is actually portraying … it seems it’s trying to do it all in the last couple of cycles based on the intermediate stream. Which closes off too soon trundles around and then lifts up the eastern seaboard while the mid level machinery is actually weakening. That’s why for the dullard uninspired solution. The previous “fun” runs had northern stream phasing, that has taken an absence in more recent cycles. However seeing the ensemble mean still having several members with pretty deep pressure anomalies between the Del Mar and Cape Cod and the spread being Northwest I think there’s probably still some members that have that phase. Just guessing.
