Replying to Current Mt. Hood conditions?

Hello all, I am venturing up to Mt. Hood this coming Friday and I cannot tell you how stoked I am to be making a fantasy reality! I know the skiing won't be the best of the best but it will tons of fun. I was wondering though, what is the weather like around there? I am planning on camping near the river and I am planning for the worst, hoping for the best. Is it going to be rainy? humid? what's the temperature going to be like? will it be total spring conditions and I'll just wanna wear like a flannel or will it be more chilly than that? Sorry to ask so many questions but I would like to know what I should pack for ya know haha. Thanks for any responses and free karamas to all!
