Which of the following best describes what virga indicates in weather observation?

Virga describes a phenomenon in which precipitation falls from a cloud but evaporates before it reaches the ground. This typically occurs in conditions where the air below the cloud is dry, allowing the moisture to vaporize before it has a chance to make contact with the Earth's surface. Observing virga can offer important insights into local atmospheric conditions, such as humidity levels and the potential for rainfall in an area.

Understanding virga is important for pilots and meteorologists, as it can indicate changing weather patterns. While all other options describe various aspects of weather, they do not encapsulate the essence of virga as the evaporation of moisture in the atmosphere before it reaches the ground.
