No rain in weeks? No trouble for snowmaking at A-Basin, Copper Mountain

There was the tiniest sliver of white this morning on the slopes at Arapahoe Basin and Copper Mountain.

Snowmakers turned on the guns overnight when temperatures dipped below the sweet spot of 26 degrees Fahrenheit, known as the “wet bulb temperature.” There was just enough moisture in the air to make it worthwhile.

A-Basin says it is all about layering: Keeping the ground cool and wet for the real stuff, whenever that comes.

In recent days Keystone also tested its snowmaking system. On Oct. 1 Loveland promised to watch the forecast for colder, wetter weather.

Forecast is not promising. Summit County might see a few raindrops between today and tomorrow, and then dry again until Sunday. Daytime temperatures remain in the high 60s. We’ve seen less than a half-inch of precipitation in the past six weeks at the Krystalized Weather Station in Dillon.

There is no opening date yet for any Colorado ski slopes.

A-Basin would have to open tomorrow, Oct. 9, to match the earliest opening ever.
