It varies depending on the track of the low coming up over the atlantic that is supposed to combine with the one coming from California. Could be more rain, could be snow. I've seen 6-18" numbers. So, in all honesty, all I know is that I have prepared, but it might be for nothing.
But they say that rather than a 6-12 hr event, this could be up to 36 hrs. And a lot of wind. So with wet snow (could get rain too after all), power might go out.
So, shovels ready, generator tested, jerry cans filled bird feeder filled

, all dry wood that I still have left is in the garage (maple and cherry), or next to the stove (oak, cedar, ash, sassafras). Bbq has gas. So I'm all good.
Except for the fact that I need to get me some bourbon for next to the stove when I can't work because the power is out
That was probably more than you asked for... Bottomline: 0-18"...
