MONCTON FIR,
I respect your post. However since you have had a lot of experience in adverse weather I would say you have been surrounded by people who have good knowledge of adverse weather also; ATC, Airfield OPS etc.
Here in the UK, Airports tend to shut at the first sign of snowfall. Runways are given as WET WET WET when really they are only damp or even dry sometimes.
I flew into a airfield this week that was giving medium/poor on the taxiways. Only until we landed and saw the taxiway, it was infact dry and the information was old depsite being on the latest ATIS.
We are NOT used to serious adverse weather in the UK. I believe the Capt has every right to go and inspect a taxiway or runway if he or she so wishes.
