Do you live in a vast expanse that needs clearing before the airport can operate...stands...taxiways...runways, how can they clear the snow when its falling so heavy??
Preperation my Ar$e...its simply fell too heavy too quickly, look at the Metars !!!!

What cant speak cant lie...bring a million staff in and you couldnt keep the place open, in order to clear the runway you need to get on it, not easily done with landing traffic...hence...SNOCLO
