Nice discussion. 1/6-1/7 definitely looks like an I-84 - north snow/wintry event. Unfortunately, we lost the -NAO blocking, also lost the -AO. Any shortwave that amps is going to want to be an inland runner/cutter. With the +NAO, there nothing to stop a SE ridge flex and force secondary redevelopment off the coast. The blocking left at a real bad time

We can snow with an okay PNA. We don't need blocking to get snow.

wall to wall winter from november to april? never again. we've warmed too much

In my lifetime, we never had wall to wall.

Even 96 wasnt

But yes, those days of getting close are gone.

What is amazing to see are places in the Adirondacks like Lake Placid that used to be wall to wall no longer are. 

We went up there every christmas. Always snowy and cold. They havent has a good xmas week in years!!

 

This change didnt happen gradually… it happen rapidly. All within 20 years

ewr: nov -4.1 dec -6.3 jan -3.2 feb -1.5 march -3.8 

five months in a row with negative departures with 4/5 -3 or lower. that's a pipe dream in the current climate

CPK hit 56 on jan 9th, and 51 on the 18th.  56 was a daily record which I think still stands.  

So yeah, no.

It was as close to wall to wall as you can get around here in the modern era.

The warm December aside, I honestly cannot remember the last time we have gone into the first week of January with less than an inch of snow. We got nothing in November and I only have 0.5 of snow total for December. In recent history, I think only 97-98 and 01-02 did this. Even 11-12 and 19-20 had much more snow by this time…..

The winter of 1972-1973 holds the top spot for the least snowiest, with only 2.8 inches recorded in Central Park.

Agree... it's about timing.  NOT a certain oscillation configuration. Preferred oscillations are valued as more lead time but even those fail, frequently.   Thought this was worded I84 and particularly the Poconos and elsewhere just too far away in this overall pattern as described by others previously to this post. I do note quite bit of NO it won't happen, so that pattern recognized thinking-experience is considered.  Think I want to wait it all out.  Even 12z/1 GFS refuses to leave I95 dry, opting for a period of snow 4A-10A Monday.

I remember plenty of rain that year. Wall to wall has never existed at our latitude in recorded history. Wall to wall warm is becoming increasingly possible, but there will continue to be intrusions of cold air following wound up storms regardless of CC.

Newark nearly caught 95-96 in just 33 days during 10-11. So while wall to wall November to April cold and snow is unlikely in a warmer climate, a shorter period of intense snowfall could eventually rival 95-96. Philly beat 95-96 in a much shorter period in 09-10. Same for Boston beating 95-96 in 2015.

Of course it's going to rain but we had below normal temps every month and over 15 snow events iirc.  It's as close as we can get around here.

GFS goes from a cutter at 0z to an inland runner at 6z to a DT special at 12z for the end of week potential event.  These types of outputs reinforce the argument about how far out these OP runs should go.

It's insane to run the GFS out to 384 hours. I don't trust any operational beyond 72.

So,  without the 12z/1 EC op in hand... I agree with the very recent post about GFS repeatedly too much snow into drying air nw fringe. IF the GFS is correct, it will have scalded the GGEM/EC, with only the ensembles prevailing for the minority of amounts (less than 1" in our area) and virtually always a dusting in the ensembles due to climo in our area in winter.

So the WPC morning ensembles are out (14-16z ish) and they have slightly lowered the threat of 1" in NYC Monday, and decidedly lowered the chance of 3" just n of I84 Thu night-Fri.  I did not add these graphics but if you do not trust, please go to the WPC Winter Weather page and check. 

Always uncertainty but for now, I take my chances on Friday morning being more productive in our area than Monday morning for one reason: Barring a 12z/1 EC northward shift, all the other primary modeling has a null event NYC Monday.  Friday is still 6 days out and we know there are going to be changes in the modeling since confident lead-time in this pattern around here seems to be less than 84 hours. 

Examples below from the 06z/1 GEFS.

Note the confluence zone is to our south for Monday morning.

But Friday morning: note the confluence zone is in se Canada.  The Friday event could still run inside and be mainly rain... but at least my  confidence in an event is much higher than what is indicated to me by the 06z/1 500MB pattern for early Monday.

Am not 100% null on Monday but still not excited til l i see the GGEM and EC come north. For now, continue Trace flurries at worst NYC Monday morning through the 16z/1 modeling guidance.

Forgot to add but most importantly-thank you for your AFD complements. Those days are long gone.  Ensembles-improved modeling have changed the game. Not being an MJO specialist leaves me kind of behind on the flow interactions. I just pattern recognize.  

I still think LR is very-very difficult to be constantly reliably accurate, especially timing the embedded 2-3 week periods of extreme weather.  

Since my understanding is that the NAM goes away sometime in 2023--- am unsure what replaces but I'd like to see the SPC HREF extended to 84 hours.  However, am not sure if that will be useful.  I always like the NAEFS 8-14 days and it might not hurt to start looking at NAEFS 15-21 Day. Again, there may not be any predictability?

And here is the 12z/1 EC at 54 hours. Slightly further north... but still south of us. No thread for me as yet for Sunday night-Monday morning. Thanks to the ECMWF and Weather.US for this graphic.
