The idea was to have a page where you could get a overview of what is going on across the country. It's not proving to be easy.
And as I said the other challenge is that there is very little regional info available for Canada.
I'm not a weather geek. Since I plan where I'm going for a mid-season trip out west well in advance, it's easy for me to focus on one place in terms of weather. Don't usually bother until a couple weeks before I leave home.
If I'm just curious about a region, I check out OnTheSnow. For instance, here's the list for West Coast. There is also a list for the Mountain Collection destinations.
