Brian is exactly right, but I might add a couple of points:
1. Rain is always a possibility during that time of the year. You can protect yourself from this to a ceratin extent by choosing a hill in the northern regions and/or a hill with some elevation. 2. If you are a beginner, I would avoid Jay Peak. You can check the trail map for yourself at
www.jaypeakresort.com , but blue runs like Northway, Angel`s Wiggle, Goat Run etc. are very busy.
Jay is my favourite place, but only in the trees trees. If I had to stick to the groomers, I would never ski there.
