Powder Skiing
The best powder skiing and low-key atmosphere within striking distance of Seattle is probably Red Mountain and Big Red Cats, which is right on the border, about 2.5 hours north of Spokane.
Big Red Cats is the only cat skiing operation that offers separate intermediate, advanced, and expert tours - so if you don't have a lot of powder experience, you can take the intermediate trip, go at your own pace, and get powder skiing tips from the guides (and a helpful hand if you fall in the deep snow and lose a ski or something).
Best of all, there's a LADIES HALF PRICE special if you book by 30 September, bring a partner at the regular rate, and come between 2-15 Jan. Your "partner" can even ski in the expert cat while you stay in the intermediate cat, (or vice versa), if you're one of those "just because I'll sleep with you doesn't mean I'll ski with you" couples.
So, I'd ski at Red Mountain, and get used to the open glades in the "mini-bowls" runs in the Paradise area for a couple of days, and then try a day of intermediate cat skiing.
Red is inland just far enough that it gets light snow, but not so far inland that it gets extremes in temperature. The best things though are that you can drive there in 6 hours and that they get 35-40 feet of fresh every season.
