Summary: Well, Dr. No, King Euro, looks like he might be back, as most of the global models tonight at 0Z caved to the Euro depiction over the last several runs of a much more progressive, flatter storm much further to our SE. So, the chances of a major snowstorm have gone down substantially, but not to zero, and the chances of even a minor to moderate storm have gone down significantly. The AI models, which have done quite well in the 4-6 day range this winter, still show a moderate to significant storm (with only one model the AIGFS still showing a major snowstorm)., while all of the physics-based models show either no snow or only a few inches. The cries you heard last night were from all the snow lovers around the world, lol.

Details: In a stunning, but not completely unexpected development, most of the global models (both AI-based and physics-based) tonight at 0Z caved to the Euro depiction over the last several runs of a much more progressive, flatter east coast trough, resulting from many things upstream, such as a worse ridge out west and poor "wave spacing" between the Fri/Sat system and our Sunday system pieces, such that they don't phase until later, leading to a more progressive storm much further to our SE. So, the chances of a major snowstorm and even a minor to moderate one have gone down substantially, but not to zero, as the AI models, which have done quite well in the 4-6 day range this winter, still show a moderate to significant storm (with only one model the AIGFS still showing a major snowstorm)., while all of the physics-based models show either no snow or a few inches.

The risk of the Euro and many of the ensemble members from ensemble runs yesterday being right in showing minimal snow and things shifting towards a minimal storm are why I wasn't going to start a thread until at least after the 6Z runs this morning (coming out soon) and I wouldn't have started a thread based on what we just saw at 0Z - see my quoted post from yesterday morning below. With regard to the ensembles, at least half of the ensemble members from the Euro, GFS, CMC and AI model ensemble runs yesterday, where the main model is run 20-50 times with initial condition perturbations to probe sensitivity) were showing little to no snow, despite every operational model (the "main" models) other than the Euro showing major snowstorms at 12Z.

Below is a bulleted summary of the differences between the 12Z runs yesterday afternoon and tonight's 0Z runs. As you can see the first 5 (the physics-based models) went from major to huge storms to very little, while the AI models went down, but not as much - they often don't make big moves in short periods like the physics-based models. It's not "over" for a major storm, but the chances probably went from 40-50% to <10% and the chances for even a moderate storm probably went down to 30-40% with a minor to no event now looking like a 50% or more chance. There's still some time left for this to trend back to snowier, but that trend would need to start by Thursday morning at the latest (when the pieces of energy come ashore out west). So, we track, as they say on the weather boards. The NWS discussion is below as is a link to the AmericanWx thread.
  • The ICON went from a 12-18" monster for everyone to nada for almost everyone (1-2" for AC to Cape May). That's nuts.
  • The GFS went from 6-12+" for everyone at 12Z to 2-5" for most at 0Z
  • CMC went from an 18-24" monster for everyone at 12Z to <1" for everyone at 0Z. Also nuts.
  • The UK went from 8-14" for everyone at 12Z to an inch along 95 and a few inches for the coast at 0Z. More nuts.
  • The Euro had little to no snow for everyone at both 12Z and 0Z. Dr. No.
  • The AIGFS went from 12-18" for everyone at 12Z to 6-12" for everyone (the high end at the coast) at 0Z.
  • The Euro-AIFS went from 6-12" for everyone at 12Z to 2-3" for 95/3-5" coast at 0Z.
  • The Weathernext 2 went from 8-14" for everyone at 12Z to 2-3" for 95/3-5" coast at 0Z.

KEY MESSAGE 3...Monitoring the potential for a winter storm this
weekend, then much colder early next week.

An active pattern looks to continue with much of the model
guidance showing low pressure sliding west to east and exiting
off the northern Mid- Atlantic coast later Sunday. This storm
looks to deepen as it does so, and has the highest potential to
be impactful across our region including the potential for an
accumulating widespread snowfall. Many of the deterministic
models show a storm, and at least some of the ensembles do as
well however they offer some variety regarding the
track/strength of the surface low. The question, as always, is
the track of the surface low. There is still a chance the system
shifts more southeastward which actually has been the general
trend of 00z deterministic guidance. A majority of ensemble and
AI guidance also trended a bit south and east. The amount of
cold air in place ahead of this storm and especially during it
will be important when it comes down to precipitation types and
amounts as well if a storm were to track close enough, as strong
dynamics may also come into play. While it remains way too
early though for specifics, and there likely will be further
trends and changes among model guidance, there remains some
signal for some sort of storm for the second half of the
weekend
Well..... there goes your boner.

In the Meteorology Is Hard category, things trended back a bit more snowy at 6Z, especially the Euro, which jumped NW about 200 miles. Can't make this up. So no storm cancel yet, but also still nothing major in the 6Z models.

Specifically, at 6Z we have the GFS showing 1-2" for 95 and 2-4" towards the coast, the Euro-AIFS showing 3-5" for 95 and 5-7" towards the coast, and the Euro-Op showing 1-2" for 95 and 2-4" towards the coast (nearly identical to the GFS). The AIGFS, which was the last model showing 6-12" at 0Z, took a big step back, only showing 2-4" for 95 and 3-5" towards the coast, but Weathernext2 jumped up to 6-10" for 95 and NW and 8-12" towards the coast. The Euro ensemble mean also made a nice bump up in snowfall. The rest of the models don't run out long enough at 6Z.

I can walk/hike outside in the high teens if it's sunny and a calm day. Wind is a killer at these temperatures!
one of the best things about the boardwalk. If its sunny and not windy or even if the wind is coming off the bay it can feel very warm up there even if its in the teens. I've only missed a day or two of walking outside this whole winter.

Yeah but you're one bad Mamma Jamma so not the best example.

Being surrounded by water makes it a damp cold that goes right thru ya when windy.

Dan Zarrow 101.5 is just saying "chance of snow Sunday" and will hold off buying until Thursday.
Makes sense. That'll be a little over three days out so things should be in better focus. As of now, the good news is that it appears to be trending toward a lesser event. Even the cold shot they predict next week has the Tuesday high at 32 which is more than enough to get a good melt on treated surfaces.

In the Meteorology Is Hard category, things trended back a bit more snowy at 6Z, especially the Euro, which jumped NW about 200 miles. Can't make this up. So no storm cancel yet, but also still nothing major in the 6Z models.

Specifically, at 6Z we have the GFS showing 1-2" for 95 and 2-4" towards the coast, the Euro-AIFS showing 3-5" for 95 and 5-7" towards the coast, and the Euro-Op showing 1-2" for 95 and 2-4" towards the coast (nearly identical to the GFS). The AIGFS, which was the last model showing 6-12" at 0Z, took a big step back, only showing 2-4" for 95 and 3-5" towards the coast. The Euro ensemble mean also made a nice bump up in snowfall. The rest of the models don't run out long enough at 6Z.
The 6Z Euro run may have been the harbinger of things to come, as the 12Z suite is starting off with a bang, with the GFS and CMC both showing a much less progressive/flat evolution (more meriodonal flow, i.e., south to north up the coast instead of out to sea) and much more snow. I'll update this as 12Z continues and the WPC seems to be on board with significant snow, now, as per the graphic below. Interesting times.
  • The ICON still didn't have much snow at 12Z, but made major improvements in track and aloft
  • The GFS was very much snowier, with 4-6" for 95 (less NW) and 6-10" towards the coast
  • The AIGFS stepped back a bit showing a general 1-3".
  • The CMC was close to a bomb with 6-10" for 95 (less NW) and 10-15" towards the coast
  • The UK moved the low about 200 miles NW giving 3-6" S of 276/195, but very little north of there as it moved too far east
  • And to muddy things up even more, the AIFS stepped back a little bit with 2-4" for 95/4-6" for the coast...
  • ...and the Euro went back to being largely a miss to the SE. So much for being a harbinger, lol.
  • WeatherNext 2 backed off a bit from 6Z, showing 2-4" for 95 and NW and 4-7" towards the coast.
So it seems like everything is still on the table from nada to 12", lol. Glad I don't have to make a forecast for anyone, lol. In situations like this I generally punt a bit to the NBM as a guess (model blend), which shows 2-5" for the area, but that's a bit of a copout. I just don't know where we're headed and I doubt anyone else truly does either.

As numbers pointed out - models this morning showing hits again after last nights models backed off.

euro run in an hour or so will be telling. Is this just model back and forth or the start of sn actual trend?

Excellent thread by Tomer Burg on X, with some deep meteorology on why we even have a significant threat despite the hostile current pattern. He mentions how that pattern breaks down at the end of this week making a possible MECS (major east coast snowstorm) at least possible. He also does a deep analysis of the Euro ensembles and how those are clustered into various camps and also discusses a sensitivity analysis and points out what to watch for in the system evolution over the next few days and what would be important to see for a big storm and the several things that can go wrong leading to a much smaller storm or a miss.

His bottom line is in the last post of the thread, where he doesn't see a huge snowstorm being likely, saying the more likely solutions are a weak/progressive system (like today's Euro) with light precip or a moderate to major snowstorm, not exceeding 12". Obviously, huge differences between those two outcomes and we'll just have to wait and see.

The kind of scenario where a high-end major snowstorm dumps over 1-2 feet of snow along I-95 is not a likely solution at the moment, but can't be fully ruled out until we have a better sense of the above (by Thursday at least).

The more likely solutions at this time are either a weak/progressive system with only scattered light Pop rain/snow (cluster 1), or a moderate-major snowstorm but with snow amounts generally capped to 6-12 inches in parts of the region (cluster 2).

Regardless, it is too soon to narrow down to which scenario is expected.



So we can get an inch or over a foot. Glad you narrowed that down! 👀
Why is anyone putting out amounts right now? Way too early. Seems like Tomer Burg is searching for a longshot scenario that fits his need to talk about a big storm.

agree I don’t see the point of showing amounts after every run.

According to 6ABC Philadelphia the Euro has this as a miss with most South of Philly and the Jersey Shore. Way too much time to be talking any specifics on a storm 4 days away.

euro, ukmet icon are still nothing

gfs ensembles are way less vs the gfs op more of a grazer like the ai euro

the only 2 models giving a moderate storm are the gfs and canadian and even then concentrates most of precip toward coast, in fact the gfs verbatim really struggles to give precip to NW new jersey and nw of 78

You are almost correct. I'd say 0-12" is the reasonable range right now. I see no issue discussing model data - it's a weather thread and people are interested in what the models say and the trends we may or may not see. Nobody is putting out a forecast yet that I know of, given the incredible range and uncertainty.

This has been such a strange winter. Freezing cold many days, much colder than the last several winters and for a much longer period of time. But many days are bright and sunny, not the typical months on end of grey days. I don't get it.

The GFS, CMC and UK all jumped 200+ miles NW (and the UK gives decent snow along/S of 195), which is notable. The AI models all still show a few to several inches of snow for most, but a bit less than at 6Z and the Euro was a big fail, which is important. Overall, this is a significant increase in snow vs. 0Z last night, but not consistent enough to make a forecast on, given several models showing little snow and the ensembles showing a decrease in snow.

By saying 1-12 is a forecast. A terrible forecast but without a doubt people are putting amounts right now.

I was thinking this. Why 5-6 days out is it snowmaggedon and then it disappears. Never the other way around. NJ just doesn’t get much snow.

You simply don't understand what that word means. It's not a forecast at all. Period. It's saying what the potential range of outcomes are and it's not even the full range - the full range is more like 0-20". A forecast would be something like 2-4" for 95, 1-2" well NW of 95 and 4-8" towards the coast. That is possible but I wouldn't be willing to put that out as a forecast and nobody else should either. That's why the NWS won't put out a forecast for the whole storm until Friday afternoon as they only forecast 72 hours out and the storm probably wouldn't be done until noon on Monday. Some folks might put out a forecast before then, but that's a recipe for being wrong.

Why would you say that? 12/14, 12/26 and 1/25 were nowhere close to going out to sea and became decent hits and even 2/15, which looked like it would be out to sea, came back over the final 36 hours and delivered 1-3". Yes, the last one on 2/1 missed completely out to sea, but it also never really had much of a chance for being a storm and never should have had a thread for it. Also, 1/17 and 1/18 did not go out to sea (but they were more clippers where out to sea isn't much of a risk). And we don't know yet whether this one is going out to sea, although it's very possible.

No I understand. But not many do. People all day coming in and talking about the foot of snow we are getting. What is even the point of posting any measurement. Just to get people interested? Nonsense. You certainly don't understand that posting measurements 4 days out is silly.
And to have any faith with the NWS in Mount Holly is also silly. They couldn't get where and how much rain we were going this morning. The actual amount was zero.

That's all you needed to say. It's useless right now. The ICON was improved at 18Z and the GFS is close to a bomb (6-9" for 95 and 9-15" towards the coast). But until we see the Euro on board there will be doubts about significant snow.

Most of NJ would collectively sh-- itself if it woke up to a surprise 2-in snowfall, let alone a real storm. Be happy it works that way and not the reverse 😄

Would be hilarious reading the ensuing breakdown here, tho.
