Yea, EPS is not as close to the coast with the wave as the op, still a long way to go for this one

Long range members look good, gonna be a tough pattern to track down which energy will be our main player... I’d expect anything significant if it happens would be a 48-72 surprise, highly doubt models lock into anything upcoming

If we end up with the same models underdoing the WAR issue which we've seen every winter since 13-14 then this has a good shot of happening

The last few winters were crazy with that, yes. Literally every model would underdue the WAR until the last 36 hours before a storm would go from being a flurry to an advisory or warning event. The one caveat is those winters all had ++NAO, which was allowing the WAR to press. As of now, the NAO looks neutral to slightly negative this time around

1 glance at this and one would think... major EC storm but the LP is set on western edge of the trof, and we actually rain/subsidence till it’s too late, far interior sees snow.. odd set up

The low on this map should actually be well inland, probably over Adirondacks given where the best divergence is. For a big snowstorm for us, that closed 500 low should be 200 miles east of that.

Yeah a little SE then we could be in business. Most important Euro run this far incoming.

Euro is a miss very similar to the gfs- we need the trough to scoot west about 100 miles and the low to ride the trough while it intensifies. Right now every model is a miss for Friday into Saturday storm

Plenty of time for this to change just our chances are looking slim.

 

Euro has a decent clipper for Sunday morning that drops our first accumulating snow 1-3 inches areawide it looks like

 

Also next Wednesday day 10 fantasy land brings a nice overrunning system that drops up to 10 inches area wide low of 983 sitting just south of long island

With the 12z EPS coming west, the OP Euro may return to showing some snow for the 9th on the next run. We'll see...

If we look back at all of our bigger snow events in the metro area since January, 2000, they have mostly come on the backside of cold patterns, as they are breaking down, not on the frontside as they get established or in the midst of a cold pattern....

With the ongoing AO-/PNA+ dual blocking forecast to be in place for Friday-Saturday, I think it's a pretty good possibility that parts of the Metro area will see their first accumulating snow of winter 2017-18. An inch or more is also on the table, as such dual blocking has seen frequency of 1" or greater snowfalls that is 160% of all other cases when such dual blocking was not present in December (December 1950-2016). Overall, things remain on course for a colder and snowier than normal December in the region.

12z gfs not a flake through the weekend. Like I said, trending in wrong direction.

“Crankyweatherguy” on twitter has a whole new detailed tweet chain explaining why this weekend is going to be a total non event for the metro area. Just snow showers that at best may amount to a dusting or coating. Here is just one of his tweets on this, check out his other tweets as well:
