If I understand correctly, then 19.00 today - 13.00 tomorrow = snow showers, visibility 400
then becoming snow + 1500 visibility.
Out of curiosity, how is snow creating more visibility than snow showers?
And at what point of visibility is it not permitted to fly (or is it airline / pilot judgement?)
