The local media reports are worthless. Of course, we are in a ski area, so snow = news = tourism $$$. But yesterday the radio forecast was 3" - 6" but what they neglected to mention is that it would be for elevations above 10,000 feet. Reality for our plowing area is trace to 2" which is exactly what our weather service told us. We signed up with Skyview Weather this year (a local service out of the Denver area, highly recommended) and they have been right on so far.
In the past, we have relied on the old "get up at 2 AM and look out the window" method as well as the Summit County Rescue Group's telephone call-in avalanche and weather report. Their forecasts are pretty accurate, but they only give one day at a time, no extended information.
Newspaper, radio, TV, forget about it. Weather.com or Accuweather are better, but still not great for our area.
