Colorado’s High Country could see up to 12 inches of snow through Thursday morning as a storm moves through the western mountains, according to a winter weather advisory published by the National Weather Service.

Snow is expected above 9,500 feet across most of the Western Slope beginning the morning of Wednesday, Oct. 14. The advisory lasts through Thursday morning.

Total snow accumulations in towns including Aspen, Snowmass Village and Vail could reach between 4 and 8 inches during those 24 hours, with higher amounts possible above timberline, according to the advisory. Wind gusts are expected to reach 35 miles per hour.

Areas in and around Summit County above 9,000 feet — including Breckenridge, Rocky Mountain National Park and the Eisenhower-Johnson Memorial Tunnels — could see total accumulation between 6 and 12 inches by Thursday morning.

Individuals traveling along mountain passes should expect slushy and icy road conditions, with the worst impacts expected during morning and evening commutes on Wednesday, the advisory states.

Temperatures are forecast to be significantly cooler than last week, with highs in the low- to mid-50s for most of the region.

Although Wednesday could be a good snowmaking day for ski resorts, as some Colorado resorts see their first snow of the season, higher peaks along the northern and central mountains saw their first snow as early as mid-September.

Several Colorado ski resorts — including Arapahoe Basin, Winter Park Resort and Keystone Resort — have announced openings in October, with actual dates dependent on weather and snowmaking conditions.
