Awesome Weather App for Skiers

This is my go to App snow conditions. Everyone I know who is crazy about snow sports uses this App. Last Xmas we skied with long-time friends and they geek out on snow conditions and forecasts with this App as well. Last January, we had to be rerouted on the Den-Jackson flight b/c of lack of visibility at the airport. Practically everyone around me on that flight had this App on their phones looking to see when we would have an opening to land at JH airport—that was the weekend of 48” of snow on Wed-Friday. If you love snow sports and have a need to know what the conditions will be like this is the App for you. From Late September to Early April, I become a total weather geek/expert thanks to these guys. My only complaint is that I wished the leading snow storm indicators could be more accurate. But like any leading indicator it’s just not possible to know for sure until it happens. These guys (I don’t believe there are any gals—although that would be a good addition) take the guessing out of snow conditions and forecasts.

Inconsistent, not worth price

I’ve used this app religiously the last 4-5 years and this app has managed to go downhill from the start. First and foremost the most consistent and detailed forecaster on this site is Evan Thayer. They frequently have one forecaster for large areas (Bob Ambrose AB/MT) and in turn lose out massively on consistency of forecasts, in addition to quality. Open Snow introduced a semi paywall 2 years ago which has led to its demise. First, they capped the quantity of forecasts you could read at 7 per week. This was announced pre-season and I was disappointed; yet understanding as they had brought on Evan and his forecasts are awesome! Several weeks later (I believe) they were lowering the quantity of forecasts you could read to 5 (which I think was further reduced to just 4) on the basis that their customers were reducing consumption of forecasts to stay under their premium pay wall. Now, I wake up today to find that Open Snow has decided to eliminate access to all forecasts other than a 3 sentence “summary” which they’ve instructed their forecasters to leave void of any useful information. This company has certainly fallen in line with the rest of the snow sports industry to gauge their supporters for as much $$$ as they can. Right on OS!

Best Snow and Ski Forecast App Available

OpenSnow is a dynamic app for researching weather and localized snow conditions in ski and snow sport areas. The map feature with radar overlay is my go to for visualizing real time precipitation, especially snowfall in the mountains, given some dedicated radar apps do not even portray snow precip. Setting my favorite snow stake and mountain webcams to get real time and review of conditions is also a fantastic feature. Navigation into the plethora of info the app has to offer is easy, and you can even save trail maps for offline use when data service fails. I enjoy and always seek the best media and apps for weather, radar, maps, webcams, and skiing. Considering these interests and time spent searching for quality options to immerse myself in them, I feel it can’t get much better than the OpenSnow app!
