Page to Vegas via Kanab/St George is an easy route.
1 good climb between Page and Kanab. The rest just rolling hills.
1 long slow windy decent into Hurricane.
Twisties going through the Virgin River Gorge (55mph on the interstate).
1 more climb out of Mesquite.
There are no mountain passes. The most likely spot for any snow would be 30mi from Page on toward Kanab. That is the highest elevation, but is still high level desert. It does snow in that area every winter, but quickly melts (usually).
Personally, I wouldn't be expecting any snow on the above mentioned route.
