Some other thoughts on this event. It's not a typical clipper as it moves SE the entire time. It also can't rapidly develop offshore, at least initially b/c it is too "crowded." The strong cold front and disturbance aloft the gave the SN to northern New England yesterday? That system rapidly developed last night S of Nova Scotia and is now intense (see 12z sfc map attached). So when it is crowded like this, another trough/disturbance so close behind it often has no "room" to develop much, and will get forced more SE rather than E. As I mentioned yesterday, this is a *darn* good snowfall for such a weak low pressure. The sfc low does not get below 1006 mb as it passes. Usually, a snowfall of this magnitude has low pressure below 1000 and more often closer to 990. And aloft at 500, it is nothing special either. Just a little "dent" in strong WNW flow. The strong Arctic high pressure to our NNE supplying a wedge of low-level cold air damning to the SW over the region makes all the difference here. Who would have thought having the mean trough position too far *east* for an East Coast weenie blockbuster could do this? CoastalWx recently told me, "this pattern BLOWS!" Ok, does it now? And it is not a case of the ambient pressure field in place prior keeping the low from not getting that "deep." The sfc high to the NE is "only" 1033 mb and center well NE near Labrador, and, as I said above, nothing much at all at 500, and even at 850, it barely cuts off one contour, so not a low-least beast like a Gulf wave often is. The 18z HRRR is forecasting up to 18" in central NY (Cooperstown area). There is no lake effect snow involved here and elevation in that area is not a factor (no little bulls-eyes on the higher areas, it's a broad 12-18" area), so 12-18" is a lot for such a weak storm like this. That much synoptic snow from a clipper? And another factor I think? It's been very mild W of New England across a large part of the country, and very wet storms have been impacting the West, so more moisture in the mean is available overall and associated w/ the clipper. So you can "blame" the more snow here from mild winter temps partially! Imagine that.

Sleet picking up in intensity

Heavy snow. Closing in on an inch. 17/15

Found @SnowenOutThere in the NYC forum. He's switched sides. Traitor!

SE Nassau not quite moderate yet. Everything whitened. Sticking everywhere of course. Starting out today with a long walk on a bright 20 degree morning, staying below freezing all day as the high clouds started moving in, with flakes falling right on schedule. What a nice day after Christmas. Older I get, the more I try to enjoy these moments.

Only on first . Has that look on radar

That mixed bag up by Stroudsburg looks like it will mix out over to snow with better rates. Allentown probably out of luck but we’ll see how much good the better rates can do.

You live in a heat dome 28 here

Roxborough/Manayunk are ideal for ice Pretty much all ZR here, tonight just got interesting

It could be your favorite weather next week. Very cold and dry.

Much of CT could outperform Boxing Day 2010….there was a big sucker hole in that one that also extended up into chunks of MA where totals were like 5-8”.

Definitely picking up quickly with bigger flakes. This will pile up fast.

I had to turn off mPING reports. 8,000,00 report about how sidewalks are being covered with snow. I'm looking for totals and trying to decipher rates. Don't need to know your sidewalk is covered

For me, I wasn't expecting much snow, even before the models trended the wrong direction. I know that we almost always flip as the warm air is under modeled. You seemed to be sitting pretty up that way, though.

Same

It’s 29 at my house in the city.

First NAM bust incoming... According to the 12/26 18z NAM (using four algorithms on Bufkit), 1.2"-1.5" of snow was expected at Binghamton before the transition to several hours of sleet. Binghamton has seen snowfall approaching 3.0" as of 5:05 pm with moderate continuing snow to fall.

There's a chance my area outperforms Boxing Day 1

Damn, that’s that mid level warmth over performing as we talked about. Mid level warmth and low level cold consistently over perform.

Mod. snow in Port Washington. 25⁰

Wow 6-12 for west Chester and over to Long Island. DT lowered NYC to 3-6” and he’s usually bullish.

Huntington Bay NY SN

Everything is covered here,moderate snow currently. It took minutes from nothing to a heavy dusting.
