Vail is huge. Lot's of powder stashes. In fact a lot of the locals are riding the front side of Vail these days, vs going back to the bowls and blue sky basin on a pow day. All the crowds flock to the back areas, and you can ride powder in the trees all day long frontside.
Though on a huge powder day, the bowls or Blue Sky can be very awesome.
Generally if this stuff is open, Tucker Mountain at Copper is also open and the snowcat is running. So it all boils down to snow coverage. Right now it's looking like next week could be huge. We are getting a storm tonight that could put down 10 or more inches in the summit county area. Next week could be measured by feet if the things come together. So you might not have very many problems finding powder runs. As a good rule of thumb, think trees for powder.
