Ya great point about the high, that really should help not just for locking in cold but to enhance the snow rates. You can get some great snow rates in setups like this before the mix moves in (mix down here at least).
Yes I agree no guarantee on a significant storm as most storms have trended less amped and have been sheared by the time they get here. Just like the Sunday storm was supposed to be a classic SWFE now look at it.
HREF early on looks good for everyone , snow down to south coast changing to rain as it ends and a nice weenie band around route 2. Definitely favored more north.
