Hey 2P,
so I just looked through the logs, and we were SNOCLO / Snow Closed on 8th Jan, a bit crappy on 10th Jan, then snow closed again on 13/14th Jan, fogged out on the 24th Jan, it was rubbish again on 5th Feb, 8th Feb and 29th Feb and 6th March - and we've been ok since, the only thing I would say is that I know the snow clearing will be a much higher priority for scheduled commercial ops - so the amount of days closed could be reduced to 6-8 easily as the airport will be making sure that ops will not be affected as it will hurt them as well if they are slow to clear the ramp and runway.
