Reply #2: Effects on the East Coast have been complex

[Dogmudgeon]

The autumn begins and finishes later; this past one, by four weeks.

It stays warm later.

We've had an early cold jetstream for most of the past ten years, leaving us with several ice and snowstorms on or about December 5th.

There is usually a period right after Christmas where a warm Pacific jetstream dominates weather for as long as 6 weeks; it was especially strong this year.

The weather turns wintry late in the season, as it did again this year; snow in the first week of April has been fairly common, compared to long-term trends.

Then, in mid-April, the temperature soars. One year (2002?), we had a light snow on April 2nd, and our first 90°F day on April 15th.

I suspect this strongly patterned behavior comes from some emerging, climate-dominating, Arctic weather system.
