bluewave Posted November 23, 2014 Share Posted November 23, 2014 It would be a very significant event for even the nearby interior areas to see a large accumulation only two years after the November 2012 snow. That one was a classic BM track which would be needed this time for the coast to share in the wealth. http://www.erh.noaa.gov/okx/StormEvents/storm11072012.html http://weather.unisys.com/archive/eta_init/1211/12110712.gif Link to comment Share on other sites More sharing options...
Isotherm Posted November 23, 2014 Share Posted November 23, 2014 If KNYC or EWR are in ur forecast I will respectfully disagree. I think there's at least 3 inches there and a hope for 6. If you mean the following then I am 100 perc with you. I think the NJ shore to the N/S boarder are done but I think once to the Hudson those 850s are minus 2 and 33 at the BL 3 plus happen there I see the warm punch at hour 108 so there's def a change . I don't need blocking at KNYC with that deep center from OBX TO CC to hang on to some snow . Yes the show is N of 80 and W of 287 but I think the city w of JFK accumulates and then the gradient is steep. I'll disagree for now, as I think it will be difficult to achieve more than T-1" in Central Park with this set-up, but we'll see. Link to comment Share on other sites More sharing options...

BoulderWX Posted November 23, 2014 Share Posted November 23, 2014 Not sure what all the 'crushing" snowfall talk is about.. it's a 3-5 n/w of 95 on the GFS... with an inch or two by the coast.. no doubt MAJOR impacts given the timing but not have to go to SNE and NE before this is a 6+ type event per the GFS http://www.instantweathermaps.com/GFS-php/showmap-conussfc.php?run=2014112312&time=PER&var=ASNOWI&hour=093 Link to comment Share on other sites More sharing options...

WintersGrasp Posted November 23, 2014 Share Posted November 23, 2014 the gfs looks to have the exact same track as 06z though slightly stronger and maybe a hair colderIt is around this time that people start using psychological methods and calling for no snow when in reality they think it's very possible that they do get snow but don't want to set themselves up for disappointment. A few inches or even more seems very possible for NYC and nearby suburbs, NOT just the interior ! (Though I guess I just jinxed myself) Link to comment Share on other sites More sharing options...

REDMK6GLI Posted November 23, 2014 Share Posted November 23, 2014 IMO suffolk/nassua border east, unless this suddenly takes a BM track the Predominant precip will be rain, maybe some snow in the beginning. Coastal hugger will bring more of an E not NE fetch. Link to comment Share on other sites More sharing options...
nyblizz44 Posted November 23, 2014 Share Posted November 23, 2014 I realize people are pyshcing themselves out in order to prevent heart break but the trend is clearly for a snowier scenario based on both GFS / Euro. Certainly dont expect a foot but our chances at 3 inches have increased markedly in the past 24 hours & lets wait & see what Euro has to say in a bit.

We'll be approaching the time in a few days to watch where the convection and Gulf low formation occurs. The further east, the better off we'll be.

Coastal hugger will bring more of an E not NE fetch. It looked like the 12z Global had the surface low move from about Hatteras to at least 100 miles SE of Montauk...so why would the wind shift into the east? Generally that track, be it with a rain storm or snow storm, will still produce a NE wind for the bulk of the event. Link to comment Share on other sites More sharing options...
WintersGrasp Posted November 23, 2014 Share Posted November 23, 2014 What is nice about this storm is that regardless of whether NYC stays all or mostly snow, (which I admit is unlikely) whatever falls will stay around for a couple days at least. The storm is followed by a very cold airmass for thanksgiving. Better than the storms that dump snow, turn to rain, then melt right away. I'd take a powerful storm that gives us 2-4" of snow ending cold, over 6-12" that ends as rain and is down to 3-4" that night Link to comment Share on other sites More sharing options...
SnowGoose69 Posted November 23, 2014 Share Posted November 23, 2014 Just looked at soundings near NYC and this is an all snow event for them, nothing from 850-925 ever really gets close and its 37/27 at the time the snow arrives with a 030-040 wind which ultimately backs...ignore snow maps, this run as it is would be all snow, I did not look at Islip but I'm not sure they'd be much different.

Generally that track, be it with a rain storm or snow storm, will still produce a NE wind for the bulk of the event. Even that December, 2000 storm...which brought huge snows to northern New Jersey...still brought the 10 inch isopleth as far east as central Long Island...despite the actual center of low pressure moving over the Westhampton Beach area en route to eastern New England. Granted there was a good deal more cold air to work with...but the principle is the same. Link to comment Share on other sites More sharing options...
jm1220 Posted November 23, 2014 Share Posted November 23, 2014 If the low takes a favorable track and dynamics are strong enough, it should snow right down to the coast. The early November 2012 storm had some of its heaviest totals not far from the shore, and that was 2-3 weeks earlier than this will be, in a very marginal airmass.
