The NAM likes to nuke-up coastal lows...but just because it is not west, doesn't mean the Euro can be tossed. I agree the Euro solution is an outlier...but keep in mind the NAM can be strung out too. In the Feb 2013 blizzard, it had no snow for SNE like 72 hours out...it was a whiff out to sea on an ugly strung out wave. It finally corrected west as we closed in on 2 days out.

 

I mostly just exclude the NAM beyond 60 hours at all.

Yeah I wouldn't say toss it based on the NAM alone, but it's definitely a flag against the EURO solution. Like many other things in forecasting, I see it as a probabilistic measure, that is, if the NAM is flat and east, that's probably a 70-30 split in favor of a further east solution, while if it's amped up and the NW outlier, probably a 50 50 or 60 40 split between the two camps on the other guidance.

 

Plenty of time left with this one for it to go one way or the other. No one should be celebrating or crying just yet :)

Well here it is. Loop it. That's almost the opposite of a -NAO. You still have troughing near the Davis Straits. It's more like a ridge later in the period that is more east based, but next week is not a -NAO. But, look out west. Beautiful, stout, and static ridge.

Wouldn't that just continue the cold,dry transition to warm, wet pattern we've been in. Unless you're talking about massive over the top ridging like last year then it would seem very difficult to get a good snow event. If you like arctic air then it's a good pattern for you but it's not necessarily snowy without the appropriate blocking regime.

Well what some of the indications suggest, is over the top ridging as you said. Last year had cutters too, so we are at the risk for those as well...but this pattern going forward after this weekend offers more storm chances I think. Then, we go from there. Tough to say how it shakes out specifically.

It's going to be cold...all guidance agrees on that.

 

So there's really no use in wish-casting for warmth. The question is in the nuances of all the storm tracks. GEFS and Euro ensembles also still have some disagreement in the Atlantic...the Euro looks a little bit more promising there for at least some east-based blocking which would be good for storms.

I'm not wish-casting, I'm just stating a personal preference for warm and dry over cold and dry. The former has little to no chance of happening, I agree.

 

Seems like there are more hits than misses on the GEFS for the second storm, although maybe not all the hits are snow.

Yeah you can always find some members to fit your fetish..lol. But overall, I didn't get a cold and dry feeling. Likewise, I don't see Jan 2011.

 

Not just "some members." Almost all of them look wet for multiple events, and many of them look cold for multiple events.
