The rapid warming of the NW Atlantic independent of the AMO may be an even bigger story for all the extreme coastal storms we continue to see.

I cant wait for when we stop complaining about JFK snowfall measurements when JFK is underwater

Haha. I remember the discussion last year about November snows killing winter. Worked for us in 2002 and 1995 and 2012. Worked against us in 1989 2011 and last year.

2002 though NYC saw nothing and 1995 it was like 11/29 or 11/30.  I think there’s definitely at least in a small sample size that if NYC sees measurable snow before 11/25 or so it has tended to not work out too well for the ensuing winter but much like the when August averages warmer in July the winter always torches for the area it’s only a sample of about 5-10 years

I will look on the positive side. That November snow prevented parts of the area from finishing the season in the single digits.

Huge gradient last year it seems. In SW Coastal CT we had 22, 8 below the 30 to 35 average range.

We came up with the idea (well Chris did) that it takes time for the pattern to reload, especially after such an anomalous early season snowfall.  If the first snowfall is later, then it's not so anomalous.

Another way of looking at it is ISP got hosed in early March.  We got 12" over the first few days of the month which brought us from single digits to 21.7".

We had 4.5" in the November 15 snowfall.

The mild up time would be when the EPO goes positive and PNA goes negative. If the below is correct.

Yeah it's not cool at all. However firmly believe this will not be as bad as last year following the approx 2 bad week period.

Trended towards the other models. It has been late on every storm this year.

2 inches of heavy rain followed by 1-2 of light snow. Too bad we can’t reverse this.;)

My poor gutters.

Let's keep chipping away at the snow average inch by inch.

It may come down to what the MJO does. The GFS has a milder looking MJO forecast than the Euro. But these forecasts can change quite a bit over the course of a few days.

verbatim that's low amplitude which might mitigate the warmth a bit-last year was stronger if I'm remembering correctly

From a hobbyist perspective, it seems like the theme of the past few years has been a general humbling of our ability to forecast general long-range weather patterns.  Certainly, LR models seem to miss the mark more often in the past two years or so.

 

(1) Is there something to this anecdote?

(2) If yes, is there some scientific basis for this?  (I was thinking maybe the MJO/PAC firehose is mucking things up.)

Speaking of the LR, the latest EURO Weeklies are out and they better be wrong.         Both OP and Control like it BN in the western quarter of the country, and AN elsewhere, +2F for us on the next 46 days.      Christmas week did not look like a gift either.       Snowfall for the 6-Week+ period looked to be 3" to 10" in and around our geographically interested fan area.

From above post:

Felicitous choice of analogy!  Posts like these are why I love these boards.  Excellent convo all-around today.  Thanks!! :thumbsup:

not much there-rain ending as snow, ground will be wet, maybe a dusting on colder surfaces if it pans out at all....

It's a wave along the front. It's not rain ending as snow.

We have seen a lot of these in 2013. We also had one in 2016 with dropped a few inches.
