Winter of 2015-16 Prediction Discussion

Here are my early thoughts... The PDO will remain positive through the winter. The EPO will teeter between neutral and weakly negative. What will really help us out is that the AO / NAO is predominately negative. NYC receives 53 inches. Please don't trash me- its only a prediction/gut early call. :mapsnow:

You just can't deny the ability of a strong Nino to pump pacific air through the cuns. But if the -epo remains wow we could see cold air hitting an amped up stj aka 09/10 just a few miles north. His winter could be an epic fail or epic

I think the definition would be "no measurable snowfall" for the sake of this thought experiment.

 

It's going to be a long, long time before climo warms to where no accumulating snow is a realistic possibility at NYC, so we'd literally need a 'perfect storm' of conditions to make it happen... but should it occur in the reasonably near future, it'll be more interesting than any historical snowstorm/sequence IMO.

 Yea, at that point you are basically shifting NYC's climate 200-300mi south.

Keep that -EPO/+PDO Pattern with the Central Pacific cold pool = blockbuster winter (my opinion). I don't think the Strong El Nino will be enough to just totally change the whole pattern, it will have some impact though.

May you enjoy many years of warmth and peace.

My zip 112 retirement co-op window faces the Verrazano Bridge. The primary home faces (view from the top floor and roof) the Freedom Tower.(considering extremes and cut offs, I may still be considered a snowbird)

I'll spend some time, December through March, tracking the Rain/Snow line.

Gut Feeling says that despite a "super" El Nino and potentially the warmest year on record, this Winter in the NYC area will be the same as the last two winters.  Warm December, cold January-March with between 50" and 70" of snow.  And I feel that the Winters in NYC will be like this for the next few years.

 

No data, no charts, no maps, no research, just a gut feeling.

Same for me. Sucks having to watch these all from the sidelines. The flip side though is no windy, cold and dry days in the teens. :thumbsup:

I agree with that. I don't think I could ever be with out the seasons here. As a surfer peopke always say you belong in California. I don't think so.

As far as this winter, I think the only certian thing is uncertainty.

Nino screams torch but other indices scream cold. My gut says fastened your seatbelt!!!

I think temperatures could be slightly above normal, especially with a warm December, but snowfall is a wildcard. Could be some potent Nor'easters hitting the coast.

All things considered I'd rather not head into fall/winter with an El Nino of this strength.
