So, how was I-80 that day?
While it's clear you had a harrowing trip, I can assure you I-80 was no day at the beach on Saturday the 8th of January, as on that day I departed Park City, UT at 0300 hrs to beat the front. Even before the front it was very dicey.
When the systems come through every few days like they sometimes do, none of the XC routes work perfectly.
Do I understand from your post you were traveling at night for much of your trip? That might be part of your problem.
Better luck next time.
