Bardufoss at -22 with snow was Good/Good/Good
To be fair to the crews in the UK it's actually easier to get good friction when it's really cold (Say -10c and below), than when it's just below zero.
........given that you know what you are doing and have the minimum of kit.
Given 3 runway sweepers and one blower you should get at least medium BA within one hour when it stops snowing regardless of temp. (25000x45m RWY)
