JB this morning:
As for snow. Week two with the negative PNA for a time vs the negative NAO means warm air will be able to fight and create oppurtunities, the risk is that storms pull far enough north before sensing the negative NAO so some places warm up ,. That is most likely from the mid miss Valley to about where I am, the northeast likes to get snow out of this as storms tend to shift south further east
As far as the week 1 sucker runs. Look every once in while you get a digging trough in the northern branch that hits the jackpot. The most famous example is the blizzard of 78, a phase 7 running into 8 storm that came diving out of central canada. But most of the time unless you can have some warm advection, producing snowstorm out of height falls is a tough thing to do. Not saying it cant happen, but a wave with a strong baroclinic zone like for instance we saw in 1994 with a few events is a better bet, and week 2 looks like we have that window
