The upcoming -NAO (Christmas week into the New Year) is projected to be east-based, in addition the PAC looks like straight garbage and you have a huge omega ridge dead center of the CONUS, an Aleutian ridge with a +EPO and a very strong -PNA. So if you are looking to stay cool and avoid a “torch” in the east, that will work out fine then. If you are looking for east coast snowstorms/nor’easters it looks absolutely awful

Yep. Still got the usual crowd in Enso forum going complete eventual mild takeover for the east into January. Don S. even. He may change his thoughts with the latest data on the NAO coming in stronger and backing west. They were sold on it being east based. Larry's having to set them straight with latest charts. I won't gloat though as, it's not set in Stone yet.

Feels straight balmy outside.

I was referring to this Friday and perhaps one or two days between 12/26 - 12/29

The model consensus is currently forecasting the strongest -NAO on Christmas as well as surrounding days since way back in 2010! In stark contrast, these 6 had a strong +NAO: 2011, 13, 15, 16, 23, and 24.

pretty significant block showing up later in the month, but the Pacific is kinda trash need to see if the block can become more west based and exert its will on the pattern, perhaps a forcing more of a ridge bridge up top. either that, or the Bering Sea ridge nudging east into AK regardless, nice to see an Atlantic block develop... just need to see some other factors become more favorable for legit shots at snow south of the M/D line

hitting 54 today has dissolved whatever snowpack remained from Saturday. Was nice while it lasted, but will take a couple weeks of warmth before (hopefully) a return to the cold

yeah and they seem to target coastal VA/NC. Should be getting a new D3 update though within the next 5-15 minutes.

synoptic wind driven events seldom materialize or verify as advertised. That's why I lean needing the convective assist - hence the Marginal. I just checked btw and they've already gone there in their d-3 sev storms outlook - tho the verbiage is rather bland.

If the fun weather can't come to you, you go to it. I don't think I've ever seen a civil emergency message for wind before. Sure its happened but must be rare

NAM/GFS do have an insane LLJ at 925 materialize across eastern CT/RI/E MA through Friday morning...so something to definitely keep an eye on if that can be tapped into. This does happen to coincide with the leading edge of the main rain area too, however, there is a stout inversion too

I tend to like those messy systems in southern New England

Good post. To put a fine point on the synoptic/orographic nature of this year, I am at 14.6" snowfall total here in Charlotte at 285'. With 4" OTG and a SWE of 0.6"

mm I'm thinking more along the lines of synoptic forcing/wind problems that are then entangled with convection along what's inevitably going to be a ribbon echo squall sinuously side winding across the area. I guess wind watch headlines may cover this come to think of it. Plus... any "subtle" discrete nature to leading convective elements that are embedded in the misty wind smearing rad wash region - dirty warm sector... Those'll be whisking along within a llv jet. Those could snap troubled limbs. NAM is a tad more aggressive with this llv wind max than the Euro ( 12z ) ...haven't looked that GFS. But the NAM indicated 65+kts at 925 mb between HFD-BED! That's a whopper if it's for real. But even the Euro has this wind maxim moving NYC to SE zones/clipping at 55 to 60. A compromise puts a potential momentum/gust problem across the bulk of the area. There's still still 2 days to tune this potential. But the soundings start to look more barotropic as this is all occurring and that means we scale back the protective inversion stuff...

Cold down here in the holler at head of the crick with high of 49 and low of 21. Not a big departure but another consecutive negative 2” remaining snow over at Frederuck house doing its job, 42 max so far there

I wouldn't be shocked if that ridging in the south is too smoothed out too. I would wager probably more of a ridge axis into the upper Mississippi Valley which could then argue for some lower heights in the Northeast The overall structure of that trough across western Canada's coast will be a big player too

nah i can't, which is why I think things are going to be one or the other. either more of a trough over the NE or warmer like the old GEPS runs. that's a weird in between

these are also means that we're looking at... it wouldn't be shocking that there's some washing out ongoing for example. members that don't develop a strong -NAO are likely complete torches with very high E US heights. however, ones that do, and especially the ones that shift the block more west, might actually just have a cold airmass in the east. wish there was a way to look at EPS members like that

Honestly, are there any analogs that have that look? I can’t recall that. It reminds me of those stagnant farts that just stays in the room and doesn’t disperse. Just persistent ass.

I'm saying we can luck into that type of setup any random winter. It's like we have a bucket of climo stuff. That includes the biggest snows ever to hit the area. It also has the warmest day ever reported. It all in the bucket. Any given winter we randomly get tossed stuff from the bucket. I don't know. This cookie is kicking my ass today lol

story of the last few years. one would have to hope that: 1) the Bering Sea ridge ticks east more into AK so you can get a bit of a ridge bridge going, or 2) the -NAO becomes stronger and more west based, shifting that ridge west along with it (also allowing for more of a ridge bridge) we have also seen models consistently overdo E US heights, so it wouldn't be shocking to see a trough trend deeper as we head closer. we'll see

You would still think you could get one of these to get squashed south on occasions but with no HP or lower heights out ahead, Nope.

I usually ignore the nonsense hype machine that is Tony Pann, but his latest post has me intrigued about the AI GFS and Euro. What were they showing?

You got alotta room to cut. Cut it to Pittsburgh, cut it to Lake Michigan, cut it to Chicago. It’s all cutters all the same
