MT-CO Road Trip Planning Help

Hey all, I’m taking a trip from Montana to Vail, Colorado this weekend. Obviously Wyoming is in between the two states and I’ve heard some troubling things about Wyoming in the winter. Would it be best to stick to I25 or would I be fine taking WY487-130 through from Casper into medicine bow into Walcott into Colorado? Are there any resources I should be using to plan this trip? I appreciate any and all advice.
