I don’t have the energy to do a nice illustration of this, but go on the website like tropical tidbits, pick the North America sector, and look at the 500 MB height anomalies on the GEFS. You’ll see a trough over the Bering Sea, a ridge sort of positively tilted from California up to the Western Canadian prairies, and a trough over the Midwest that looks like it should do something here.
Now go to hr 174. Notice that Bering sea trough sends a s/w into the nrn plains of the US while the east coast trough almost tries to sharpen to make things interesting.
However, that nrn plains s/w acts as a kicker and does not allow it to sharpen to bring a low up the coast.
But here is the fun part, that s/w digs enough the of course the ridge retros into AK just enough to sharpen that and bring a more messier system into the northeast. That’s been our luck. Go forward through day 8 and you’ll see.
Now the reason why I’m saying it’s a non-0 chance is because it wouldn’t take much to bring that storm up the coast and at least graze us with a high-end advisory snow… But it just goes back to what I’ve been saying there’s just too much crap interfering in this flow.
