Whistler weather

Anyone an expert on this? I'm going out March 7 - 14 (anyone gonna be out there around then?). I can't wait. My first trip out west. The combination of caffeine and thinking about it is enough to make my heart explode.

Is the weather predictable there or is it like New England, where forecasts are a wild guess? I looked at accuweather which has the 40 day forecast. I realize this is about as accurate as sticking your finger in the air. On the 9th and 10th (a long way away) they're calling for hi temps of 9C (48 F) and 9 and 7.5 cm of rain. If my calculations serve me correctly that would translate to a buttload of snow. Can it be that warm in the valley and snowing in the alpine?

They can't predict the weather the next day so 10 days is a bit of a stretch. The valley to the alpine is 5000' so there can be a difference of 5-10C between the two.

I'll be in Whistler from the 11-19 of march, maybe we could hook up for some turns, PM me about it.
