I was at Jay two weekends ago, and at Sunday River last weekend. Didn't ski this weekend. Jay was really bad, less than 50% terrain open and melting fast. They don't make a lot of snow, because usually they get plenty of natural, and it shows this year. I did here the area's in upper Canada mentioned above are skiing great and they got snow instead of the rain in NE for most of the winter.
I am not sure about Stowe, I do think they make a lot of snow. Sunday River in ME has made a lot of snow this winter, and they had their guns on for two days last weekend. They have the best conditions I have seen this winter. They are about 75%open and very good coverage on most trails. If they didn't make snow, the trail is closed. I also skied Attitash last weekend and not as good as SR, but decent.
If I were you, I would go to SR in the next 1-2 weeks before it melts. SR plans to stay open till May 1, and they might make it.
