Everyone up north got hit with 15-18" of snow last weekend night (March 2-4). That built up some awesome base for them. It was warmer this week I think, but there should still be plenty of snow I'd expect the hills to be ~90% of terrain open, parks should all be open, what will most likely be lacking is any gladed/off-piste terrain which suffers the most because they can't groom it.
FYI they are doing Krazy Daze at Boyne Mountain this weekend, place is probably sold out and will be a wild party, although I hear the slopes are usually pretty empty since everyone is busy drinking beers instead of skiing/riding.
IMO as long as it isn't raining, it would be a great way to cap off your season up there. Wish I could join you
