Replying to Banff Conditions

So I'm from the East Coast and am currently on a ski vacation with my family. We're spending tomorrow and Wednesday in Fernie, which is currently pretty warm, but we still have to decide where we want to go on Thursday/Friday/Saturday. Banff is defiantly a good spot, and has lots of good terrain, but we were wondering what the conditions there are like. For us to drive all the way up there, they would have to be pretty decent. So if any Banff locals could hook us up with whats going on up there, it would be greatly appreciated.
