Oh, I missed the obvious on that one. I thought it was more esoteric like SWFE or FROPA.

GEFS has notably more AK ridging, than EPS. Would love to see a more +PNA.

What is "cola"?

Are we so back yet?

Thanks CAPE. Not germane to this thread but when Googling I came across a Wikipedia article on the Ridiculously Resilient Ridge which was our friend in 2013-2014 and 2014-2015. Of general interest so I link to it here. https://en.wikipedia.org/wiki/Ridiculously_Resilient_Ridge

Yes, but what I did not understand is that the blockage is not a simple consequence of the existence of the the geopotential height anomalies, but rather some additional factor which causes the patter to remain stationary.

I'm philosophically opposed to parsing operational at D10+ but I am curious; I would describe this as a +PNA but also a +EPO: there's still a huge area of low heights in AK. Would that be accurate?

So what you're saying is it's not the pattern of the geopotential height anomalies that cause the block, but the fact that the anomalies are stationary? That tells me that I know even less than I thought I did.

I second this question. I have heard many comments to the effect that a ridge over Greenland does not equate to a block, it's the dipole between the ridge and the 50/50 low. There is a big dipole there. Well it is a bit south and west of 50 N 50 W, but it's not really that far.

I'm all for it, but I think to get meaningful cold in the SE that AK trough needs to exit stage left

I just heard Harbaugh started a blog devoted entirely to long range snow maps. Might be right up your alley.

I think he meant to say, "there is no OVERstating..."

At this range, looking too cold is usually a good thing.

No explanation, but I have to mention that someone posted JB saying he thought a trough would retrograde from the east. Maybe he was on to something.

It's their first 4+ snowfall in several years, so I am happy for them. I root for everyone to get snow as long as it doesn't directly steal from MBY which is not usually an issue.
