There's a whole thread with links to Rocky Mountain webcams. The closest one is at the Peter Lougheed Visitor Centre.
I think a big problem is that the Rockies just have a ton of micro-climates in each valley. With forecasts only for Banff, 'Bow Valley', and Nakiska Ridgetop, you're left to make up your own guesses on the Spray/Smith-Dorrien Valley or the Lakes region.
Basically, there just isn't a forecast, and you'll have to expect everything and anything. I'd tend to plan for snow in the Smith-Dorrien, cloudy with sunny breaks in the Kananaskis Lakes, cloud with a couple flurries in the lower Kananaskis Vally (S of Kidd), and a dry mix of sun and cloud in the upper Kananaskis Valley. Meanwhile the Bow Valley will be mostly cloudy and windy. That's how it seems to be every time I go out regardless of the forecasts. I just use the forecast to tell whether I can expect dumps of snow vs light snow, and whether to expect -20 and below, or -5 to -15 or zeroish.
Or learn to make your own area-specific forecasts based on reading the data yourself.
