Whether the ENSO state is positive, negative or neutral, our wintry weather chances mostly depend on the Atlantic, other factors in the Pacific and the Artic. El Nino winters can suck just as badly as La Nina winters.

El Nino winters can suck like La Nina winters but are we more likely to see winter weather if the NAO/AO are neutral/positive in an El Nino (strength similar to this season's La Nina) compared to a La Nina.

At least it's a safe bet the weather will be interesting across the country. I take solace in that.

Ninos are more likely to have a +PNA at least, and an active southern stream, giving us more storm chances when they can ride north up the coast. Ninas are far more likely to have crappy cutter and dry-clipper patterns like this that favor the Midwest or New England. The Atlantic certainly helps, but Ninos just as a blank slate are more likely to produce big storms here than Ninas.

That is true; but I'd rather hedge my chances in seeing a weak La Nina than a weak El Nino in any given year. Weak El Nino episodes typically are not strong enough to impact the sub-tropical jet in the winter as much as moderate to strong ones do. On the other hand, La Nina summers tend to have relatively more scorching temperatures and more active tropical cyclone seasons.

Yeah, but that was partly my point! Third year Nina or Nino is generally weak. It's hard to sustain a strong anomaly that long.

Wasn't that also combined with the end of the +PDO cycle? 50-51 was the same deal in the last -PDO regime, and only 11.6" fell in Central Park that year. Ninas in a -PDO regime have been shown to act "worse" than Ninas in a +PDO regime because of the effect on the PNA, although those are rarer.

three year or longer la nina's..

JMA data has la nina/negative winters from 1869-70 to 1875-76...1872-73 was the best winter..1908-09 to 1910-11...1908-09 was the best winter...1915-16 to 1917-18...all three winters were great...1920-21 to 1922-23...1922-23 was the best winter...1942-43 to 1945-46...1945-46 was the best winter...1954-55 to 1956-57...1955-56 was the best winter...1973-74 to 1975-76...1973-74 was the best winter...1998-99 to 2000-01...2000-01 was the best winter...
