Yeah, here in the lower mainland (Vancouver BC area) it's been very unusual. On balance it's been a better than average season -- we got so much snow in December, and such good weather that it makes up for a questionable January. Actually this January hasn't been that
much worse than normal. This temperature inversion hasn't been as drastic for us as expected, i.e. it's not a heat wave on the mountain, just above freezing.
What's interesting to me is that I never paid much attention to this stuff before I started snowboarding (I hated winter too). I think this is the first big winter temp inversion that I've really noticed.
Still, I wish it would go away.
