I live in the Boulder, CO area, and as far as i know the i-76 corridor got the worst of the storm but is now open. Main highways around here are clear, but there is ice in some spots. Nebraska DOT is not showing I-80 to be closed but it does have it marked "extreme caution" west of north platte so i would expect ice. I'd take a set of snow chains if i had to go out in that area. You might not need them, but certainly would be useful. Conditions should be improving throughout the weekend, no significant weather should be coming through, and it is supposed to be sunny!
