Given antecedent airmass and tenor of the season over the last 6 weeks, this has felt like a C/NNE threat to me. This is not to say western and higher terrain of SNE can’t score some love but nothing noteworthy to me.
We'd be talking prolific totals for just about everyone if we had some semblance of an Arctic air mass. As it current;y stands, we are lying all the dynamics of the storm to draw in the cold air aloft down to the surface.
I'll defer to the masses but given how strong a storm signal this upcoming one is, I'd be fine with a separate thread at this point, even though we are 4-5 days out.
We're going to need to watch what occurs over the west coast. It appeared as though there was piece of energy that dropped south that sharpened the downstream ridging allowing that secondary s/w do dive further south.
