Basically that mega solution tucked into the coast that the Euro had a few days looked more like the image below, with the big closed low cut off over the deep South. Right. Those two streams have been disconnected on most guidance. Time's quickly running out for that to change. Link to comment Share on other sites More sharing options...

That's a big adjustment given how close we are to the storm. If the storm ends up as strong as the Euro shows then I think it'll end up on the BM. A track from the Bahamas to the BM is great for SE NE, not so much for the NYC area. I dont know why everyone keeps referencing the BM (40N 70W) for this storm track. We need a different trajectory or inside the BM Link to comment Share on other sites More sharing options...

USCG RS Posted January 2, 2018 Share Posted January 2, 2018 No. I only care about it shows happening at the surface (as a weather fan). Shows a miss at the surface where I'm at. The upper levels tend to dictate what happens at the surface. Remember models are just predictions of what algorithms have come tofether to predict. That being said, I understand that you are just a fan, however the art of forecasting is understanding the physics well enough to understand why the model is incorrect.

What you are seeing is the third piece of energy acting as a kicker and therfore it shunts the storm east in a quick manner. In reality, the question becomes where the crucial third piece of energy comes into play. If it phases with it around the mid Atlantic, then you have an unprecedented storm. If it acts more as a kicker, you have a significant storm for the area with fierce winds at the coast, but she's in and out. The 12km Nam was a perfect phase for all three which allows it to slow down coming up the coast and absolutely explode. Again, as has been the case this whole saga, it all comes down to kick or phase. Yeah, that's what the 12z run just did. There is time for this to change over the next few runs. But the changes from the Bahamas to Hatteras have been very dramatic over the last 2 days. I will give that old control run credit for an early heads up on how low the pressures could go in this storm. Link to comment Share on other sites More sharing options...
SnoSki14 Posted January 2, 2018 Share Posted January 2, 2018 Very impressive system regardless of what happens. You rarely see a sub 960 low near our latitude outside of a hurricane. A few models/ensembles even show a sub 950 mb storm. Link to comment Share on other sites More sharing options...

mikem81 Posted January 2, 2018 Share Posted January 2, 2018 What the heck is that 995 LP way out east of the main. Could it be causing the escape east? Is it a fiction? Link to comment Share on other sites More sharing options...
NJwx85 Posted January 2, 2018 Share Posted January 2, 2018 The problem is so easy to see. That lead shortwave is still the culprate, it's been there since the beginning. It stays a separate entity of the trough until past our latitude. The only reason why it's even tracking as Northerly as it is is because of the strength of the Western Atlantic ridge and the orientation of the mid-level jet thanks to the digging trough. In other words, no real mechanism to draw it back to the coast, so it forms out East and then moves North from there. We almost need the surface low to track over OBX. We don't need a huge shift, but we need at least 50 to as much as 100 miles and that hasn't happened yet. Link to comment Share on other sites More sharing options...
jm1220 Posted January 2, 2018 Share Posted January 2, 2018 Id definitely still pay attention from the city and east, since the precip field can improve on later runs with the better evolution aloft. But I agree about the kicker energy being a problem for really wrapping this up. If that doesn’t change by tonight I don’t think it will be anything more than a 3-5” type event around the city. It is looking a good bit better for eastern Suffolk and eastern New England. Link to comment Share on other sites More sharing options...

I could see a feb 13 style deform setting up out over the forks. Add that too winds gusting to at least 60 and it’s a serious blizzard. West of say Islip we are just getting scraps. It will sill be a nice event, as 3-6” on western LI is nothing to be ashamed of Link to comment Share on other sites More sharing options...

I think the winds on the backside could really over perform given the pressure gradient. The strong gusts (40-50+) plus single digits temperatures will yield widespread wind chill advisories and warnings. Link to comment Share on other sites More sharing options...

NYCGreg Posted January 2, 2018 Share Posted January 2, 2018 I am not saying that the Euro is wrong on this one. But you do realize that even as the snow began to fall with the Blizzard of 2016, the Euro was the one model that refused to cave to a snowy solution for the area. Similarly, with the Blizzard of 2015, the Euro was the last model showing the two to three feet of snow for NYC and massively busted. And, as I read twitter, many mets are throwing it out. I'm not a pro met by any means, and the Euro certainly has some support for a swing and a miss here, but the Euro has been pretty bad lately, particularly with these big storms.

NJwx85 Posted January 2, 2018 Share Posted January 2, 2018 1 minute ago, HeadInTheClouds said: So what you're saying then is we should ignore all the other models that give the NYC area more precip such as GGEM, UKIE, NAM, RPM, etc. We should just hug global models like Euro and GFS which have been correcting west? NYC saw a few inches in January 2015, as they might on Thursday, which fits what I said perfectly. Secondly, the RPM, NAM and GGEM are LOL worthy. If the NAM still has that solution tomorrow night I might believe it. The UKIE is a respectable model, but it's on the Western periphery of the guidance envelop and still mostly a miss West of the city. The RGEM is also a respectable model, but it's been jumping around a lot, and we're still on the outer edges of its useful range. To quote a friend of mine, models should be used as tools for forecasting, they don't make the forecast. The upper air pattern doesn't lie. The closed 500mb vort is 50-100 miles too far East and no significant changes have occured. All the pieces are well sampled at this point, and we're running out of time. If you live on Long Island or in Eastern New England, congrats, this is your storm. If you live in NYC proper or close, a few inches are possible. North and West of the NJ TPK look to see very little. Link to comment Share on other sites More sharing options...
