The euro ensembles look pretty nice in the 11-15 day. They continue the theme of very cold air seeping into the CONUS from western and central Canada. The se ridge doesn't look terribly robust on this run.

As usual, models may be a hair too fast, so if you keep that in mind..I think things seem to be slowly edging closer.

The main signal that the 12z ECM OP gives me, however, is that the pattern change continues to be pushed back. That's one sign that it's not happening this winter, reminiscent a bit of the excitement in 07-08 when the models/ensembles began to see a big Rex block over the Pacific bringing brutal cold and snow threats to the Mid-Atlantic, but it always stayed out in the long range. At first people were saying the pattern would change by the end of December, then the beginning of January, now it's solid warmth out to January 10th...The tenacity of the vortex over the Bering Strait/AK is indeed amazing this year.

Also, I disagree with Mark about those maps showing a -NAO, looks solidly positive to me with a 490dm vortex over Baffin Island and high heights centered from the Azores north in the Sub-tropical Atlantic. Definitely think any hope is going to be with the Pacific side for a while, and even that is looking pretty crappy right now.

The OP run can't see far enough out though for the pattern shift...so you wouldn't be able to tell anything from it. Even if it could see out far enough, looking at the OP run in the D8-10 time frame is the same as look at the OP GFS or any other model that far out...it has very little skill. That is why we tend to look at the ensembles.

GFS run to run consistency at least models a ridge into AK for three straight runs. (far as I looked back) I have not been barking about a change all season, I think it may finally be coming. Consensus seems to keep us in this pattern until the 10th. I think clear pattern change around the 20th. Right in time for you to track a massive winter storm the day after I leave.

When did I say anything about the Euro past day 7 today? All I said is there is no snow on the Euro like some are hallucinating there is. We are snowless period

That may be, but the way you worded it...it makes it sound gospel. It's fine, I just cringe when people start to look out and try to make statements on what they show, when the skill is so bad. You are right in that it looks crappy, but I would feel the same if it showed a blizzard.

I think the one thing op runs can try to signal..is some sort of a change..either warmer or colder. What I mean is that if you see the op runs (this applies to the GFS op) start to shift violently around in either direction in the 11-15 day, sometimes it signifies a change down the road. But otherwise, they are useless imo during that time.

For the last few days, the GFS has shown an AK block consistently in the long-range, and the 12z had a massive ridge developing over the Bering Strait at the end of the run. However, the 12z GEFS didn't really agree with the modeled changes on the OP and have low heights remaining over AK with most of the United States seeing above average temperatures:

That's the only thing that kind of has me conservative. I'd like to see them hop on board as well. It may be the GFS progressive bias, but sometimes we see the models cave towards each other...perhaps weighted to one suite more than the other. Either way, I like seeing the more accurate set of models show the change, but we have to realize that they may be rushing the change.

It's sort of a split between each model and its own ensembles. 12z ECM OP keeps the +EPO/+NAO intact while the 12z ECM ENS have a much more favorable regime over the Pacific. 12z GFS brings a massive AK block in the long-range, as have many of the operational runs of the GFS, but its own ensembles don't agree and have a torched CONUS with the monster vortex remaining over AK. I don't think we really have any consensus for a pattern change up through mid January.

The 0z GEFS were a bit more interesting with the vortex weakening and getting pushed into NW Canada, which at least allows some cold air to drain into the Northern Tier and the CONUS. However, the 6z and 12z GEFS went backwards and had the vortex restrengthening and much further west over the Bering Strait which allows for southerly flow across all of Canada.

Here was the 0z GEFS 11-15 day temp anomaly map, much better than the last ensemble suite:

Out at 180 hours on the wx underground maps I thought maybe it was attempting some anafrontal action, or maybe a gradient event set-up. I know almost every time this year that has failed. Once it gave Northern New England a decent event.

We had a lot of snow out on this property in Jan and/or Feb 2004. I first set foot here in middle February when it was for sale..walked it with snow shoes to check it out. I recall a solid 2 feet and areas to 3 feet +. I guess there were some good events in the interior.

Cold like modeled is fine. In and out...I should be so lucky...

But continuous dry cold ala January 2004 is tough. The only thing saving that was the historic nature of the cold...coldest January in 111 years at BOS.

Jan 2004 has the coldest 3 day stretch on record at ORH...the average temp for those 3 days was a bit colder than -2F.

That month there was so much suppression it was awful. We got a few light events to keep a modest snow pack, but overall cold and dry is no fun.

Odd I had 21 inches that month including a 6 and a 9

Looks like there was a few inches on the ground back then but the total snowfall for the month was only about 12 inches, at least it looked and felt wintry, not exciting but Id take that in a heartbeat right now.

I thought January 2004 was great. It had brutal cold (coldest in Ct since jan 94) and we had a couple small snow events, including the SECS on January 28 that dropped a good 6+ inches of snow.

Yea I remember 04 as a fantastic winter month. By the way what does your name mean. The Sox need a real closer!
