what does 100% humidity mean?

What’s the ratio of air to water at that percent? Is there a cap on the amount of moisture in the air? Is it the same for different elevations?

The air becomes solid water!

But seriously, it is just the max amount of water that the air can “absorb”. It is a relative number, and the physical amount will vary based on air temperature. So 10% humidity in cold air is not the same amount as 10% in hot air.

Basically if 100% humidity happens, than it is likely to rain. Keeping in mind that humidity also varies based on altitude as well, so if it is X amount humid at the surface, it means up high where it is colder, the % humidity is likely to be more, causing high potential for rain.
