The warm water will help enhance things but I think this year the El Nino will be a variable you weight 65% at least so compared to last year it will not dominate the pattern. In my opinion, I think that westward shift in SSTA's is so key here. And we just need to keep that warm water exactly as it is off pacific coast. If it gets to skinny I wouldn't feel too comfortable.

With signs of a westward shift in NINO with its potential weaker outcome (check out PDF corrected CFSv2 projections of Nino 3.4) I am getting more excited than say I was a month ago. In terms of the NAO I agree with you, the pacific will likely play a bigger role. Regardless, I would feel more comfortable if we get that Atlantic cool pool a little further south. I am looking at a blend of analogs right now but I think when I make this winter forecast in Mid October I am going to be able to take a pretty strong stance on winter. Will I be right? I guess we can talk about that in March haha.

The early 2016 projection shows mostly warm water in those areas. Gonna be a lot more warm air rising up from the Equator than in a typical neg NAO (el Nino effects, even with a western bias). At some point that all has to hit cold air and make snow (and perhaps spectacular snow), but at what latitude? Also, not all that much hot water in the Gulf of Alaska, with a cool zone just to the south. So, do we still get an RR Ridge over the west coast, and the northern jet dipping into Pennsylvania once again? Or back to more zonal flows? Again, too soon, just a few rough observations from the gallery. In a few weeks you will have some snow reports from Siberia, more Nino development, and hopefully the picture will start to focus a bit. I'll stay tuned!<br />Jim GAnonymousnoreply@blogger.com
