Seen When Relative Humidity is Under 50%

Virga is produced when precipitation falls from high clouds into extremely dry air (low humidity) and high air temperatures below. (Virga is commonly seen across the desert region of the Western United States, an area prone to both low humidity and high temperatures.) As the liquid raindrops or ice crystals hit the warm, dry air they absorb the high levels of heat energy which energizes the movement of their water molecules, transforming them straight into water vapor (sublimation).
