the extreme case of which is Venus with its 300 km/h jets or 60x the planet's rotation speed (compared w/10-20% the rotation speed on Earth). Look for that number to go up under GW.

CFP here in Winchester. Pretty clearly shows up on radar.

Tremendous poleward surge of tropical air...is this the Archambault event or is that next week? NAO doesn't tank until then.

At BOS?

And Gardner is shown instead of Fitchburg

I think it was a few years ago, we had a thaw clear to the Arctic Circle...was that the same year as >0c 850 at the North Pole...?

and wouldn't such weirdness show up first in the lower troposphere...I mean, CO2 is a heavy gas, so its effects should in theory be concentrated there. Meanwhile you have more normal synoptics above it with less CO2 concentration, where the gradients still exist. Could also speak to the strength of the PV despite a radically warming Arctic surface... the added heat simply isn't getting to the mid-and upper troposphere (not to mention the stratosphere) so you can actually have it colder there. Just speculating.

This seems like two seasons ago ('16-17) when we had weeks of fast laminar flow south of 40N owing to high heights in the tropics that just wouldn't budge for most of the winter, over a wide swath longitude. I remember many posts from you about how we couldn't get any digging or slowing of the flow. You think we're setting up for a similar thing this go-round?

sad trombone, wa wa waah

Well, a slight thaw, rebound to normal or a little above, but Black Friday isn't exactly Hot Friday.

I wonder if it's different here in SNE. BOS also has better correlation between BN temps in November than BN in October with a good winter. But ideally, it's best to have both BN around here. This year, however, the warm water off the south SNE coast might put pressure on that, bringing the baroclinicity farther north than would otherwise be the case. Certainly enough to get us in the game and hopefully you too.

but the company song is awesome!!!

I don't know with what equipment you could even clear a 13-meter high snowpack. I think they used to use rotary plows in the Sierras (before tunnels and other road coverings that is) or Going-to-the-Sun road in Glacier NP. Are there machines that tall?

or the spa at Sukayu Onsen in Japan

We need one of those calming rooms with lights:

yup

Corresponds well with the period of max occurrence of noreasters.

Says it all about New England's diehard fans. Summit cam from MWN

The last two weeks have really taken a bite out of our SSTs...still warm south though to fuel our coastals. Images from 10/11, 10/18 and 10/25

Good to see Quebec puts down a healthy snowpack in this deal. Probably not the same correlation with Siberian snowpack/SAI but will help those early-season Quebec highs to lock in cold air (like that really happens in Dec. :)) Now where you WANT the snow right about now is south of Hudson Bay, like it's doing. I read somewhere, don't remember where, that a rapidly expanding cover south of Hudson Bay in late October is very important, and what you want to see for a good winter in NE.

Yes, it seems the atmosphere (or the current state of it) must "learn" how to storm and then "practice" it.

Yup the first one went to like 949 mb or something crazy like that off HAT...actually performed as modeled https://en.wikipedia.org/wiki/January_2018_North_American_blizzard
