Driving from So Cal to Colorado in 5 days. Been checking weather through NOAA and others I got from this forum, but I guess I need the peace of mind from you guys. What is the weather "supposed" to be on Dec 31 when driving through Utah and Colorado on the I70? The plan is to drive those sections during the day when the temp is highest and the visibility is up. Any help would be so great. Thanks. -Scott-
