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" 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.
