Low Ceiling
We sometimes hear the "low ceiling" term used in air traffic.
In aviation, a low ceiling means "low hanging fairly continuous clouds." This condition typically can cause delays in departures and arrivals of planes. Other weather conditions that cause delays include low visibility, thunderstorms, icing, and high winds.
Nobody wants delays, more so cancellations of flights. But, as what I always tell our passengers - you would rather be on the ground and be delayed or canceled rather than take the risk of being in the air with not-so-good weather.
I don't like low ceilings, but I captured this accurate description of a low ceiling with a touch of a sunset.
