Pretty decent warm-up coming after Nov 3rd for most of the sub-forum which should last till mid-November. Impressive -PNA and +AO means much of the PNW will be below normal and the east above. EPS and GEFS both have a ridge just east of the Aleutians and it seems to stay put through mid-month. Looks like a typical Nina pattern. To put things into perspective, previous La Nina's like 2007, 2008 and 2010 all featured a warm-up in November.

Just a food for thought post. I saw someone else posted elsewhere that It was New York's warmest 5 year stretch of winters on record for the past 5 winters. I checked out Detroit and I was surprised to see that it was a tie here as well for warmest 5 year stretch (though it was all 15-16, 16-17, 19-20, as 17-18 & 18-19 were much colder). 2015-16 thru 2019-20 tied with 1928-29 thru 1932-33 for warmest 5 year stretch of winters, with the 5 year winters mean over 3° above avg (doesn't sound like much but significant for a 5 year stretch). 

1928-29 thru 1932-33 avg snow: 41.1"

2015-16 thru 2019-20 avg snow: 41.8"

period of record avg: 41.1" (current avg 43")

 

So despite this 5 year warm stretch snowfall was around avg. I could find 5 year stretches of MUCH colder temps with below avg snowfall.. Moral of the story? At a northern latitude, don't let reds and oranges on a 2 and 3 month out map worry you as much as individual patterns.

I'm at the point where even mediocre is okay on paper as long as it actually feels like winter for a month or two. Just gimme a couple of okay snows, a few 3-4" ones and maybe an 8-10" incher (that's pushing the boundaries of mediocre, but maybe the rest of the season will compensate) and I'll be happy.

Quite similar atmospheric and oceanic weather patterns between this year and 1988, also a Nina year. 1988-89 was one of the strongest La Nina's in modern times and also came after two Nino's like this year. However, I don't expect this years La Nina to be similar in magnitude. 1988-89 was a mediocre winter and was fairly dry, which is unusual for our region.
