Rain/snow line in Colorado today is 9,500+ today, falling to 8,000 tomorrow and 7,000 Saturday per OpenSnow. Fortunately precipitation forecast is negligible until tomorrow night. Aspen, Vail and Steamboat have purple mixed precipitation icons on their OpenSnow forecasts for today, but with low probabilities. Summit County is farther east, higher, colder and does not show the purple icons. Jackson has the purple icons today with snow level of 7,000 feet. Last week and yesterday it rained in the Tetons to 9,000+.
I was in Aspen in March 2004 at the end of a 3 week warm and dry spell. Our last night a storm came in and rained to 10,000 feet.
While Utah's main issue is drought, there has been some rain (up to 9,500 yesterday!) and almost no snowmaking opportunities below 8,000 feet. Thus the World Cup relocation announcement.
