At this stage it’s too early to say for sure this will be entirely PNA induced An epo ridge dominant pattern is colder but way less snowy than a nao blocking based pattern. I'm not in favor of that trend. Link to comment Share on other sites More sharing options...

Maybe its one of those meteorological impossibilities. I suppose the EPS weeklies need to be reprogrammed. Link to comment Share on other sites More sharing options...

Were that not the case, yeah bits and pieces come through with little/no fanfare. Link to comment Share on other sites More sharing options...

I suppose the EPS weeklies need to be reprogrammed. It pretty much is impossible. DT has has videos before explaining that. The downstream pattern makes it extremely hard. You might be able to get an east based weak -NAO but that’s about it.

This run simply consolidated the PV over the pole and lost both the epo and nao ridging. Probably just a bad run given all the trends the last few days.

Of course, his answer was that DT showed that it was, well, pretty much impossible. And we all know he is the master of meteorological impossibilities. Looks like we may need to get some of the model physics updated. Link to comment Share on other sites More sharing options...

See 93-94 and 14-15 where more or less the NAO was positive the entire winter both times Many of our best snow periods came during a -epo and -nao regime. That is what seasonal guidance has advertised for Jan and feb. Thats why many are excited. A -epo + nao pattern is "ok" but not something to be that excited about. Sometimes they work but often they are better for places north of philly and ice or mix to rain events here. It's difficult to get a -nao if the epo ridge is too extreme as that would tend to favor troughing downstream in response. But if the epo ridge isn't too extreme you can get a ridge bridging across into the nao domain too. That's actually our ideal look for snow in the mid Atlantic. It requires an extremely weak PV and negative AO but that's what the idea was. Furthermore the EPS doesn't show an epo ridge. It simply lost the ridging on both sides so I have no idea what your post had to do with my comment on the EPS. Link to comment Share on other sites More sharing options...

An extreme EPO ridge and western -NAO block probably wouldn't be able to coexist, but a slightly negative EPO and NAO would. His statement was a bit misleading though and one would interpret his words as him saying ridging cannot occur in both areas. Link to comment Share on other sites More sharing options...

Thus the more followers, the more dramatic the drama becomes - a self feeding frenzy. Still think if someone actually put together the right team with the focus on weather in the right way, they could put TWC out of business. Heck, there's probably about a dozen or so of the mainstream posters here who could do that very thing. Link to comment Share on other sites More sharing options...

psuhoffman Posted December 21, 2018 Share Posted December 21, 2018 The euro was kind of jumping right to the end result. The cfs weeklies get there but a week slower. They look a lot like the euro at the end early January. I think we still get there either way but maybe the analogs that suggest it's January 15-20th on are going to be right.
