Cork's RVR tends to change rapidly as it's low cloud rather than fog that causes the problem. It never stays below CAT 2 for very long which is why I think Ryanair acted too hastily in switching their morning departures to Shannon. All 5 flights would have comfortably made it in if they stuck to their original schedule.
Always better to go by actuals rather than forecasts when operating to Cork.
