We were destined/doomed to regress back to our long term average after the bonanza seasons since 2000. It would be more stunning if we didn’t. We’ve had awful stretches here before- most of the 1980s, late 1990s etc. We’re probably entering one of those. If there’s some more “permanent” state where we won’t see snow vs we otherwise would, I’d give it several more winters at least before calling it. This winter was just horrendously bad in all sorts of ways that hopefully won’t repeat anytime soon. The PNA was as hostile as it’s been in several decades as Bluewave pointed out. If we’re entering a long term -PDO state, we will have lousy winters more often than not. The warm waters off the SE certainly pumped the ridge somewhat but I see it as more of a response to the awful PNA.
I do see the climate shifting eventually to a point where it’s just too warm to snow here often but it’s probably a few decades away at our latitude. 2021-22 was decent to good for the eastern half of LI and 2020-21 was a very good winter for many of us. There are more ways to get a snowy pattern here than DC, which unfortunately for them the warming Atlantic doesn’t help since they don’t really benefit from more Miller B type lows. Maybe if this Nino happens it can be a test for them since that favors earlier developing Miller As from the Gulf.
