The modeled pattern is about as favorable as you can get.
I see zero suppression risks and multiple snow events, some big once the pattern settles in.
Could easily be a 3-4 week snowy period imo.
Now I'm curious was there any similar pattern that is currently depicted that didn't produce at least one significant snow event in the northeast.
Let's say in the last 30 years
That Dec 5/6 system could trend more favorably with blocking already having an effect on it.
Notable compression taking hold. Maybe it'll turn into a swfe.
A rotten block in Dec/Jan is better than latter Feb/March. At least climo is still better.
That being said the Pacific does actually improve over time so reloads are very possible
I'm not worried about that when PNA is still negative to neutral and Nina forcing tends to keep heights low out west.
This is a lot closer to 10-11 than 09-10 which was also a big Nino year.
Coming pattern looks closer to one that favored all 3 cities picking up 6"+
Also seeing AO forecast dip below 3 for December. Usually a good sign for winter
Noticeable Pacific improvements on days 5-7 on the EPS
Results in models bringing in colder changes a couple days earlier and then it stays favorable the rest of the run.
That's key and signals this evolution is real.
Ignore some of the ops though. They might waver a bit until we get closer to this period.
Ensembles show us the way
Op runs beyond 3 days are worthless.
The idea remains the same and I think models will get colder as we approach the blocking period.
2nd half of December will be snowy and feature one or two big snowstorms
