I would not go to WG next week. Even if conditions were good, it would be too crowded. I was there Wednesday 12/21 and it was already a zoo.
If you happen to run Mac OS X, you can try a free demo of my weather software which has some skier-specific features:Wx weather software
I am able to use the longitude and latitude of WG to get a very detailed forecast and also use an elevation adjustment to compute snow quality. Next week does not look good, and it probably won't be cold enough to make snow at night even up on the mountain. I'm a bit worried. The season has been great thus far, but this warmup could set us back.
