March is typically a very snowy month for that region. For Colorado that is generally our snowiest month. With Brianhead being in the storm track for the same snow, I would imagine that it's it's snowiest or near to it's snowiest month. All that said, you can still get skunked any month. That's the problem with weather.
If it's not snowing, it will probably be sunny and warm, which can be just as good as a powder day imo.
