Seems to me we had a rare case where high res models overestimated the WAA induced QPF overnight....usually its the reverse that happens but probably due to the overall setup being weak we had a less common case where they overdid things.

The forcing should be a bit better Fri if it evolves. Just concerned if it's soley the inverted trough that lots will be screwed by it. Always difficult to know where

I hope so, because there were likely some additional minor accumulations.

Of course we all know that from the observations after 7:00 there had to be at least several tenths of an inch (0.3-0.5 maybe) added to the 1.4 inch storm total at the park but their history is not to add to the total and just ignore it like it never happened.

It will probably be the case again unless someone that cares is measuring at the Park today. The only time they seemed to get somewhat accurate measurements was when they had the Conservatory doing the measurements at the Park several years ago, and that lasted 4-5 years. Not sure why that relationship ended.

It'll be north of where currently shown, you can count on that much...not sure I have seen one not go north over time

Winds now NW and temp down to 31.3 in Syosset.  31.7 was the high.  Roads are wet and fine on drive to Great Neck.

is there a latest Central Park report? I can't find anything since that 1.4" this morning

[HVSnowLover]

I don't want to complain about a snow/frozen event but this storm has been meh. The snow rates were putrid and now it's slush with some icing.

Beautiful wintry day..

Is it even reliable or accurate? I picture a hobo sticking a ruler on top of a trash can

That's currently the latest report.

Some decent ice accretion here near my job by Washington Square Park. 

[ag3]

NYC, LGA and JFK are now at 32 degrees.

 

[NCPOW]

Up to 30.2 with light freezing rain. We’ll be interesting to see if the temps start to drop now.

It's 30 here now. Can tell the difference between 20s and 30s with ZR, when it was in the 20s it was icing a lot and now it's mostly wet/slush.

LGA and NYC back down to 30

[lee59]

I got up to 32.3 a few hours ago, now 31.8.

[Stormlover74]

From Upton

Also, latter half of this afternoon, temperatures are forecast to lower more from NW to SE, with column cooling and surface to
7-8 kft still has much moisture. Looking for snow to redevelop and allow for snow to mix back in from west to east. This will
be pretty brief for Eastern Suffolk but longer farther west.

Still freezing rain here in Clifton. Snow and snow pellets at home in Vernon.

Unfortunately your picture is more accurate than you think.

Hey, that's my procedure!

NWS LSR snow reports through 1230PM attached. Colors indicate the amounts which are basically heavier to the sw of NYC.

Also added the 12z, 24 hour snowfall, from-via NOHRSC..which mirrors NWS reporting. 

[wishcast_hater]

Radar NOT filling in as FUTURE CAST was showing as well as what the METS were saying. 

Yes, I know future radar is completely unreliable. 

[HVSnowLover]

Almost all models still show a bit more snow later from NYC on NW with around an inch more Westchester on north.

Here are the latest Snowfall (storm total) reports for our 6 climate sites.

 

EWR - 2.1

NYC - 1.6

LGA - 1.9

JFK - 2.0

ISP - 2.1

BDR - 2.0

[Picard]

23F and back to snow in sparta.  I'm right on the snow/sleet line as per the radar, and that seems to be accurate based on real time conditions here.

[Stormlover74]

Flipped back to sleet

So what happened meteorologically with this that it’s basically raining with temps in the 20’s for many. I’m assuming that means the upper levels are too warm? How did that happen when the storm started off so cold and with lots of cold air in place?

Curious and don’t know enough to explain. 

Low offshore deepened just enough to push associated 850-925 above freezing temps back to n.w. as it passed, reverse process now underway, soundings showed +1 at 925 and +2 (C) at 850 mbs. Low is not very vigorous so boundary layer inflow was too weak to bring temps up above freezing at surface.  

General comment, link below is excellent for tracking upper air conditions:

lol was just about to comment on that, though maybe they have not yet updated after this morning?
