Thanks again for the feedback.

That can have a big impact... it's called winter. Not that you can't drive in snow, but the locals have problems

. Also, I17 & I40 meet in Flagstaff and have been closed occasionally in recent years due to snowfall/ice. It was -18F in Flagstaff on New Years day this year!
(It never ceases to amaze me when the TV reports from the closures in December and show little Johnny and Sue in shorts with no coat shivering in their car because mommy & daddy didn't know that had to drive through the mountains in AZ on their way to see granny in LA.)
I'd budget an extra hour for the drive in February... just to be safe.
