Dave Aguilera Rain in the Denver metro area changed over to heavy snow early Tuesday evening. The temperature at 6 p.m. in Denver was 34 degrees, so the snow so far hasn't been sticking on roads but that will change overnight as temperatures dip. Slick roads developed quickly during the afternoon drive in and near the foothills. A jack-knifed semi-truck slowed down commuters that were traveling along Interstate 70 near the Evergreen Parkway through early in the evening on Tuesday.
