Soundings show a pretty good easterly wind at the surface... explaining the warm BL. Assuming that's correct, not great for NYC proper.

NYC 6-hourly raw gridded temps that I'm coming up with:

Wed 12Z: 36

Wed 18Z: 38

Thu 0Z: 36

Thu 6Z: 37

Thu 12Z: 36

Thu 18Z: 37

Fri 0Z: 37

Fri 6Z: 37

Anyway, I'd chop 2F off the surface temps but that's still a bit on the warm side, Maybe if it thumps 18Z Wed-0Z Thu like it shows, it'll be colder than that. Could happen.

I wonder if this will be similar to what happen in ct a few days ago....good thump....a inch along the shore....2-4 just inland....

The one idea that the Euro continues to hit on is that the GFS and even the GGEM to an extent are completely out to lunch with the warmup as the secondary low forms. The Euro has it forming hundreds of miles south of the other globals...off the coast of Ocean City MD.

That's what I'm skeptical off. I don't buy the OP Euro solution. A strong low in the Upper Midwest isn't likely to develop secondary low that far south.

Agreed, just something to track as well. What did the GEFS show did it agree with the op?

It did agree with the op. The GEFS has been awful this year so I wouldn't take it seriously. It is good that the euro went more south instead of north. The GGEM and Euro are almost similiar.

Yeah, I feel like this 12z Euro may be a bit of a tease run, but we'll see. Usually w/ the primary going through Michigan, the transfer occurs east of NJ. A primary up through Ohio then a transfer to MD would be more believable. I'd love to see accumulating snow, but I still find it difficult to buy into the GGEM/ECMWF solutions.

The system last week that gave VA 5" of snow was an entirely different synoptic set-up. Very strong confluence across NNE with a well placed 50/50 low near Newfoundland. More importantly the short wave originated in the southern stream and never phased w/ a nern s/w, allowing it to stay further south. This week's storm has no 50/50 low, a strong, but retreating high, and a phased northern stream short wave w/ the primary cutting thru Michigan - all bad signals for us. If we (NYC south) get anything more than a coating to 1", I'll be very surprised.

GGEM,Euro and Ukie all snow accumulating snow for the area. I would like to see the GFS come on board. The confluence up north is stronger on the GGEM and Euro than the GFS. With a -PNA, it's possible that the euro ends up right. We will see what the models show tonight and tomorrow.

Snow for NYC? Highly doubt it. More like a mix to rain later... NYC seems to be right on or above the freezing mark on the models. I believe the GFS is correct with this storm thus far.
