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.

To be frank it makes me nervous. We want the pac jet to extend enough to keep the Aleutian ridge at bay but too much and North American cold goes bye bye. It's a delicate balance.

I like some of the trends for later in Jan on the "weeklies", but the low heights currently progged for AK on the EPS leave me unenthused for the first 10 days or so.

I'm just going to save Chuck the trouble of posting: 507 dm in Alaska means not cold enough.

No kidding; I was never sold on Tua even coming out of college. I don't question his heart but he just doesn't have the body to take NFL pounding, and it seems as if he just doesn't have the skill to do the reads if his first target is taken away. But he had that good year at just the right time and they threw ridiculous money at him. I was kind on interested in getting a fan's eye view of Lamar though. For an outsiders view it seems as if he is stagnating. Maybe it's just the injuries or the line play or a combination. I wonder if he might benefit from a change of scenery.
