This is where I'd really like to see a much more expansive snow pack up to the north. Had we not endured such a mild period for so long, we may have had that. But alas. The air is quite cold up in Canada, but it will be important to see how strong the high ends up being. The usual trends that we see are to weaken highs through time and for the entire height field to be less suppressed as we close in. It's one of the main reasons I very much favor overwhelming suppression out at longer leads.
My guess is is that the the foothills and particularly the mountains have the best potential to see more than an advisory event. I would favor the Piedmont areas for some wintry weather before changing to rain. The good news is, if this one does amp up, it will have a good chance of laying down some important snow cover up north, which will have a good chance of sticking around, as it looks like we're moving into a better pattern, finally, for east coast cold.
