Powder Potential Forecaster

Boosting up Weather Underground's coverage of where best to shred, this just-launched forecast map allows you to zoom in on any mountain in the state (and anywhere else in the country) and view "which resorts are likely to provide the best powder" for up to five days in advance, as well as check in on detailed mountain info like how many runs and lifts they have going -- as with people, good indicators for which ones are in the best shape.
