I've been feeling that 22nd system for a couple of days now...was just waiting to see some model truth of it coming west with the southern stream system. It just has that feel of something that "wants" to phase sooner. You can see the surface isobars kinking back toward the northern stream almost south of NYC. It almost seems like the models have an event horizon with these things...get 2 shortwaves that are strong enough, close enough, and then they develop a sooner attraction.
We'll see.
