I think 2017 is the only exception, with the historic cold 2nd half of December/first half of January. We stayed overnight (might have been 2 nights) at AC for my sister's 25th birthday, and it was way too cold to go on the Boardwalk. That year, we didn't get the warm-up until mid-January, and we all know about that record warmth in February. Then, of course, the cold/snowy pattern came back for March and April.

Even before that 2nd coldest late December 2017 into early January 2018 period, most areas from Philly to NYC Metro still made it above 55° from the 17th to 25th like every year since 2011. Many of those years the long range models missed that warm up. But once we got past the first week of December, the models played catch up the closer in time we get to the period.

Yeah I think 2018 was the year where in southeast parts of the US all the trees opened and there was major damage from frosts in March and April

Besides the “blob” situation, a pronounced -PMM has developed as well

 Today’s Euro Weeklies update:

1) 4th run in a row with a very weak SPV late Nov/early Dec with today’s having ~25% of members with a very early major SSW, the highest yet of any run!

2) After having warmed up significantly in the E US the last 3 runs for most of November/early Dec from the cold Nov 2-9 and then mainly NN Nov 10-Dec 7 of the Oct 26 run, today’s has cooled back down notably for much of Nov 10-Dec 7 and is downright cold for the new week (Dec 8-14) with a solid -AO for Nov 24-Dec 14. Keep in mind that the Euro often has trouble seeing cold too far out. So, seeing BN all the way out at weeks 5-6 in today’s run is noteworthy and will be followed closely for future trends:

I don’t believe that’s where we would want all the storminess. That’ll keep knocking into west Canada and west coast and the ridge will keep rolling over. Not a good look to funnel in cold arctic air into CONUS, which is necessary for our snow chances.

We need ridging into Alaska to drive cold air south from there. A more rounded ridge pointed into Canada would just bring Pacific mild air in. In December especially near the coast the source region for airmass is very important. And obviously a roaring Pacific jet would tend to knock the ridge down and nudge it east.

 Is it my imagination or does it really take an extra click to get to this thread now?
