Haven't been there recently, but I can extrapolate based on Sugarloaf: Thin and very firm natural base covered with manmade, very thin coverage on natural snow trails. I think they're about 65%-75% open today, but that will change by the weekend depending on what this current storm does on it's way out on Friday.
Current thinking is that it'll drop some snow on it's way out, potentially enough to improve the existing skiing but not enough to open new terrain (4" or so of snow).
