Blowing snow closed highways in north and south Colorado Monday, and is dumping up to a foot of snow in some parts of the mountains.
Interstate 25 was closed from about 5:30 p.m. to 8:30 p.m. Monday from Wellington to the Wyoming border; southbound U.S. 285 was closed midafternoon at the New Mexico state line and into New Mexico, and remained closed at 9:30 p.m., according to the Colorado Department of Transportation.
The Front Range cities, though, weren't getting much precipitation at all. Some parts of the Denver area reported light snow Monday afternoon, and light snow hit Colorado Springs and Pueblo later in the evening. No significant accumulations were expected.
It's a mixed bag in the mountains.
Chains are required for commercial vehicles on Colorado Highway 9 over Hoosier Pass, for example, while the Breckenridge ski area was reporting no new snow.
Chain laws are in effect on many mountain roads and highways, including Interstate 70 at from Golden to Glenwood Springs.
Ski areas that seemed to be getting heavy new snow include Wolf Creek, where the resort reported 12 inches in 24 hours. Crested Butte reported 10 inches, and Monarch Mountain reported 4.5 inches.
But some blustery winds are expected to follow the snow, with predictions of wind chill factors on Tuesday reaching to minus 30 in some areas. A high wind watch is in effect for a chunk of north-central Colorado, including Boulder, Jefferson and Douglas counties, for Tuesday night into Wednesday.
Leadville was getting heavy snow and freezing fog Monday evening, according to the National Weather Service. The forecast called for a wind chill of minus 25 on Tuesday.
Forecasters called for a minus 10 wind chill Tuesday in Woodland Park.
Colorado Springs is likely to get a bit of that wind, with a forecast for "breezy" weather Monday night and wind gusts on Tuesday up to 30 mph.
Temperatures are expected to drop, with an overnight low Monday of about 11 degrees. Tuesday's high is expected to be about 35 degrees under sunny skies.
