Ratings and reviews

Edit: 8.5 years later and Opensnow is better than ever. The team keeps adding awesome features. Worth the money to subscribe. Joel and Company have done a wonderful job with both the site and this app. The forecasts are excellent (I usually view BA's in Tahoe), and the app is packed with features like bookmarks for your favorite hills with up-to-date conditions and webcams in the app itself. Well worth downloading, and their subscription service is super reasonable too if you want to upgrade.

The Gold Standard Go-To for Ski Mountain Weather! I check the temp, the wind, the precipitation and most important for my bright & low-light sensitive eyes -- the cloud coverage -- by the hour. And of course, the snow forecasts. Handy too for entering the cities along Colorado i70 to check what road conditions are likely. Excellent emails & posts as well about what has happened and what's coming. Get OpenSnow now...it will become your most used weather app.

Best all-around ski app out there, maybe my favorite for weather in general. Trails on an interactive map with tons of useful colored layers. Forecasts and conditions broken down any which way you want. Very surprising feature is the ability to click on the map and get a projected forecast for any specific spot in a second. Human commentary is a nice cherry on top - reminds me of Space City Weather.
