Pattern January 2021 - Joyless January

See, this is fine with me. I know it's a 384 operational, but I'm simply looking for signs that arctic air will be nearby and that it doesn’t just shoot in and out. As you can see, there's plenty of cold around our part of the world. And it is like that for much of the run.

The devil is always in the details, but as long as we have real, bona fide cold nearby, then we are in the game, and I feel good about that. I do not feel good about marginal situations and modified or stale polar air where we have to rely solely on dynamic cooling. That's much more of a low percentage way to get a big widespread SE winter, than to have arctic air incorporated into a storm.

With a cold air source available, now we will wait for shortwaves in an active pattern to make use of it. Hopefully, we'll see that play out soon.

Here is the 7 day 500 mb and 850 temps from the ensemble 00z runs.

-PNAs aren't going to have the same meaning when you have a gigantic block over the Baffin Bay, we aren't going to be warm and dry in a pattern like that. Just because you see a huge western trough over consecutive 5-day means on an ensemble also doesn't mean that pattern is gonna persist the entire time. It's more like transient western troughs that hand off towards the Lakes and slide underneath the block. We definitely run the risk of getting Miller Bs & ice storms w/ this look esp if the TPV drops towards the CONUS and we get a properly timed wave over the southern Rockies

Yep, that'll do it. All we need to do is drop the stupid -NAO, and go back to a +PNA and -EPO. Barneys then show up all over the southeast. LOL. What you're saying is we need to go back to 2014.

If we drop the -NAO, the -PNA will rage and we'll torch.

No.
I was going to say. Sure let’s do that and punt the rest of winter. Hello last winter? Really the biggest thing I see different so far is the -NAO and it’s saving our ass

and that was directed at the post that you replied too. Lol

No.
Do you have any thoughts as to why we keep seeing these blockbuster long range patterns beyond D10 slowly evaporate as they come closer? Other than my theory about model resolution and the persistent Greenland blocking somehow being overamplified and causing all these modeling errors, that's all I have.
 
No they do not. Which of these are you willing to bet is more right.?.I’d rather air on the side of the EPS and be pleasantly surprised if they are wrong.

Yeah for sure. Although, it seems like one of those winters where the chillier scenarios may be favored? Probably NAO related. I guess we'll see soon enough.

Once that subtropical trof kicks SE of Hawaii we should be good.

That's one of those things that JB always harped on...having a trough east of HI is a good thing for the east coast.

Yeah a +PNA in the right spot is good. Our -EPOs of late haven't done us a lot of good, but that doesn't mean they can't, if coupled with a well-placed western ridge. We've seen a lot of western troughs in winters of late. I like having a -NAO, and I'm glad we finally have a winter where it's showing up on the reg...or at least appears to be. But as I've said, we need a mechanism to inject some non-modified arctic air into the SE. Otherwise, outside of a very lucky intersection of events, congrats Texas and northern mid-south and midwest and mountains and northeast and Canada and Russia and Europe and Mexico and everywhere except most of us in the SE.
