In Alberta we are skiing a month earlier and a month longer than we did in the eighties. Largely due to snow making. I think they could go longer but it's hard to get the crowds once the golf courses open. Sun angle is what melts the snow at any rate. Has more of a bearing than rain or a couple of degree difference in temps from year to year.
