Not much to be optimistic about. Jan could see some action first half as cold tries to bleed further south despite unfavorable PNA.
I do think mid-late Jan through mid Feb will be a torch as we lose blocking temporarily. However I expect blocking to resurface later on with the -PNA no longer acting as a deterrent late Feb & March.
I'm expecting 30" most of which will come in late Feb & March.
Which is why I was never excited about this pattern. Two months from now this would be an excellent pattern though.
And I do think this pattern will show up again in late Feb/March where most of our cold & snow will be.
They will have a lot more snow than us. Looks a good winter setting up for them, maybe even historic.
We could def thread the needle in this pattern. We've had much worse patterns. Nothing crazy of course but some snow.
Highly unusual and convoluted pattern that will wreck havoc on the models. Models still attempting the phase shortwaves for 22nd which will have implications for future events.
Strong -PNA coupled with strong Atlantic blocking. Everything is destructively interfering with one another.
Now if this were mid-late Feb or March we would be sitting pretty given wavelength changes but as it stands it's one big mess.
On its face no December snowfall in a Nina is bad but we've seen a lot of things that we've never had before lately.
Maybe this could be the first time we see 30"+ after 0" in December in a Nina.
Theres plenty of cold air around but it's focused out west. Canada is very cold as well.
Places that don't normally get snow out west will get plenty of it. Seattle & Vancouver and most of BC will see an unusual amount of cold & snow.
Hopefully that's what happens. However those crazy negative anomalies off the west coast make me think otherwise.
I am getting 2007-2008 vibes though. Central/northern New England will score huge in this pattern. SNE is on the fence.
Anyone further south is cooked if things don't improve out west.
A negative NAO/AO combined with a strongly negative PNA/PDO in late December/January will lead to a gradient pattern that favors New England.
It's very 2007-2008 esque with heaviest amounts in central/northern New England
I would wait a few days. The wild Pacific jet is causing day and night changes over a span of a few runs.
It could easily flip in 2 days. Anything after 3 days is highly speculative on the op runs.
Nice Xmas blowtorch on the Euro.
Blocking doesn't mean squat with a record negative PNA/PDO.
If you thought the anomalies for the US were warm before just wait till next week. Should easily be the warmest December on record.
