PH
Sometimes precipitation begins falling normally but evaporates or sublimates while passing through dry air below the cloud. Meteorologists call this virga. From a distance, it can look like streaks hanging underneath a cloud that gradually disappear. The ground underneath may remain completely dry even though rain or snow formed above it.
Virga can also contribute to strong downdrafts as evaporation cools the surrounding air. Sometimes, a rain ****** ends before it ever reaches Earth.
