Weather apps that report snow accumulation Are there any weather apps for iOS that report the amount of snow accumulation, not just precipitation? Something like "3-5 inches of snow is expected".

I've tried the stock weather app and several others. All I seem to get is whether or not it will snow and the amount of precipitation which is merely a fraction of actual snow accumulation. Ideally I'd also like to know if ground/road conditions are expected to be icy.
Dark Sky shows expected accumulation... In my experience it is pretty inaccurate, but it tries. It has almost always forecasted more accumulation than actually accumulates. It is pretty accurate with its other predictions though.

The prediction engine that runs Dark Sky is available at http://forecast.io if you want to try it out for free. I can't remember for sure if it shows expected accumulation, but I think it does.
