I should mention that it warmed up at louise later in the afternoon, and the snow got a bit heavy. It needs to keep snowing overnight for it to be good tomorrow. Snow was still coming down when we left.
Also, a ski patrol guy on the chair told me that it was raining today in golden/revelstoke/fernie. Apparently louise/sunshine were the only places cold enough for snow. I'm not sure if that's true, but it might be worth checking before heading out tomorrow.
