    The models unanimously weaken that fronto forcing between 700-500mb where the DGZ is, so if this is correct, +SN may not make it into the area this afternoon.

    Yeah, looking likely that will weaken by the time it gets here.  We'll get some light to moderate stuff early, then main precip shield in that late afternoon/evening window.   

     

    SE wind is helping to moisten the column a bit already though, it won't totally fizzle even if best fronto forcing is the west.

  2. SE wind may help moisten things a bit and limit virga.  That said, little more of a riming signature on this EC, too.  That has been a bit of a trend today, finding a warmer nose in the DGZ, would likely take ratios down a bit.  Think I'm gonna stick with what I had earlier, which is mostly a coating-2" city, LI and 2-4" N and W as well as CT.  Further up the HV and into northern CT is where you get your 3-6" stuff.

    Very marginal situation and I think best case scenario here goes something like getting some snow at 33-34 in the city for a few hours.  Gonna be tough to stay colder than that with that SW wind past say 21-22z.  Think if you're a bit further north in CT, Hudson Valley, NW jersey...better chance to get yourself a couple of inches before it flips over.

     

    Implied, but the mid-levels and even most of the lower levels are OK.  The issue is sfc to like 950mb with high gone.

     

    The main issue the Euro is presenting isn't really the temp profile early on.  It's more the precip being slower to arrive and losing out on getting some needed precip with the colder air still in place.  Think early ballpark of like 1-3 north of the city, coating to maybe 2" at the absolute highest in the city (bias for lesser end of range) and less than that south.  

     

    I think I'll nudge areas just north of the city to 2-4", keep coating to 2" for the city, Island and south.  You head further up and gain some elevation in and northern CT you'll find those 3-6"  type of amounts.  Thicknesses will be rising throughout the event and you'll still have low level warmth to deal with after 21-22z or so. 

     

    I still have a tough time in the city seeing anything more than 2" in a WAA type of scenario like we have here.

  4. I think the northern portions of CT and as you get further north in the Hudson valley can do much better.  Decent forcing, less of a sfc issue.  Get some elevation and you're probably looking 4-8".  I do still think even 20-50 miles north of the city you're gonna accumulate a couple of inches for what it's worth.  This is just a pretty tough/marginal situation for anyone in the city, the Island and a chunk of central Jersey.

    Surprised to hear it was that high, see this wasn't an epic bust for the city outside of the immediate ocean areas and Manhattan

    It really wasn't, but a little bit of UHI goes a long way in storms like this.  You get the complaint that it didn't "feel" like 5" of snow because you lose accumulating precip to still warm paved surfaces.  And it's a valid point in terms of population impact. 

     

    It's still a bust in the city though.  No one said the job was easy!

    NOHRSC interpolated 24hr sfall through 12z/4. imageproxy.php?img=&key=20fe2b78d4e66dffimageproxy.php?img=&key=20fe2b78d4e66dffSeasonal total in this part of Wantage now 34.7.  I thought the banding was well modeled by the NAM and in the resultant s+ area (colder profiles and larger dendrites easier to accum). Max today so far was 31.8 ~630A. now 28.9 with increasingly gusty can and partial sunshine.  We may not get past 32 here in northern Sussex County NJ today.  No matter, melting and settling in progress.

    10 miles makes all the difference, but close only counts in horseshoes and hand grenades.  Tricky storm.

  8. Event post-mortem...

    Call: 6-10" NYC Metro, north shore LI, NE Jersey, lower Hudson Valley and CT

    3-6" with mixing Jersey shore, south shore and the forks.

     

    What worked:  

    Lower Hudson Valley, NE Jersey, Connecticut.    Generally aligned with expectations there as dendritic growth was solid, band cranked out 2"/hr snow rates.  Widespread 6-10" totals verify.

    The mixing idea along the Jersey shore, south shore and forks held down totals there.  3-6" will verify for many, but barely.

     

    What busted:  Central Park ASOS is reporting 5", which is an inch lower than my forecast.  I consider this a bust for Manhattan, likely a chunk of Queens and the north shore LI pending OKX final storm report. IP line was far just enough north during the  evening we lost snow to sleet, that makes a difference.  That, plus a temp of 33 led to very little accumulation until the band came through.  As a result, busted too high on low end of range for lower Manhattan, northern Brooklyn and I think Queens (though I may squeak by there, 4-8" would've been a better forecast).    I consider SI and south shore Brooklyn as a coastal area, I'm not overly surprised there was less snow and mixing there.

     

    In short, the northward tongue in the mid-levels was battling against some pretty impressive snowfall rates.  Should've been more cautious in LI and in NYC specifically given this is March.

    3-5” was the proper call. NYC could get close to 5”.

    Yeah it's gonna be close for me.  I went 2-5" NYC and north shore LI, 3-6" CT, NE Jersey and lower Hudson Valley.

     

    I was dealing with some skepticism from  traders on my floor with this yday because there was so little hype on it.  Selfishly I want the full verification.
