Stevens should be decent. They have gotten some good shots of snow. There was a warm up though. I wouldn't call it a waste of time. Beautiful area. If it is just pissing rain, drive over to Leavenworth, drink some beer. There is a good chance it wouldn't be raining over there anyway.
We did get a crap ton of rain up there early this week, but they will be open. Only a couple lifts will be turning (probably Hogsback, Skyline, Brooks, and Daisy) so there won't be much open. Probably a small park open as well. But it does look like it is supposed to be sunny.
