Yeah I don't get that...I suppose we oughta just ignore it unless other guidance starts to show it. And besides, how often do we get ice when it hasn't been cold leading up to it?

(Real question, actually...not entirely sure) The CMC/GEM was insistent on a warm start, and all the other models caved to it 24 hours before the event. Hopefully something like that happens with the GFS? Link to comment Share on other sites More sharing options...

(Real question, actually...not entirely sure)It’s going all in on a cad setup with a decent hp in place over New England. Who knows. Agreed, that there will be practically zero fzra concerns with the recent temps. 1 Link to comment Share on other sites More sharing options...
CAPE Posted February 1 Share Posted February 1 There is a pretty complex split flow pattern that probably explains some of the differences between the models for mid/late week. GFS is notably less amplified than the Euro. Link to comment Share on other sites More sharing options...

Not necessarily, and split flow patterns tend to be more difficult for models to resolve in general. Most other guidance is more in line with the Euro. 1 Link to comment Share on other sites More sharing options...

Which is more than 15 Why are you going with the warmer less accurate guidance over the colder more accurate guidance? I've just seen the look models before.. it's a difficult one to change. If you really want to get down to it, we have a Weak Nina right now.. even during the late Nov - mid Jan cold period there was +OLR and +SOI, and other things Weak Nina-like, especially during the end. In late December the subsurface ENSO went from Neutral to pretty moderately Negative. I've researched this, and run numbers, and a negative anomaly in the central-ENSO-subsurface region at 150-200m correlates to -PNA conditions. Because it didn't happening immediately when the cold pool flared up and was a bit lagged, I feel it may stick around longer now. I've seen this time of year -PNA... after Jan 27th, the coldest day of the year, it's like a switch flips, and we go -PNA for whatever reason. Because it's aligned with the warming/cooling cycles of the Hemisphere, it seems to be somewhat of a permanent pattern. I think you agree that the snow prospects are slim for the next 15 days. If the pattern goes more -EPO like the EPS has, that favors maybe some ice, but models are pretty consistent on having an East Coast/mid atlantic ridge at least through day 15. Beyond there, you seem to be bullish on it getting cold again, but I've seen these LR ridges try to change a -PNA in the long range, by overtaking the NAO or whatever, and they don't work out as well in verification as you would think.. the RNA pattern is a stubborn one and can be difficult to change. I do think we could see some breaks, but probably not the late Nov - mid January cold that we just experienced. It's hard to pattern change. That doesn't mean that it can't happen, it's just a little lower confidence right now on the Day 16+. 1 Link to comment Share on other sites More sharing options...

I do think we could see some breaks, but probably not the late Nov - mid January cold that we just experienced. I don't think many are expecting the magnitude of cold we just experienced- or at least I hope not. It isn't likely to happen. Good news is we don't need that. February likes to snow on us, and the pattern being depicted around mid month and going forward could certainly produce a MA winter storm. Whether it actually does or not is another story. 1 Link to comment Share on other sites More sharing options...

Whether it actually does or not is another story. A lot of the long range factors were unfavorable for cold/snowy though.. it's important to keep that in mind when looking ahead to the long range, the QBO is still record positive, which with a Weak Nina favors cold 10mb conditions, or at least not a Major Stratosphere warming. People can freak out about the 10mb PV being split, but it's very close to a near neutral anomaly, so the best that is, imo, is a "not super +AO". -PDO, west-based Nina, etc... If the MJO can stay strong going into Phase 8 late February, maybe that is something to watch, but I've seen this Scandinavian ridging trying to break that NAO in the long range before, and it seems to be something just runs with more -PNA. We'll see I guess. Link to comment Share on other sites More sharing options...
