What's a virga? It happened at the Oregon coast

LINCOLN CITY, Ore. (KOIN) -- Wispy finger-like clouds slowly pushed onshore Saturday evening near Lincoln City. This weather event is known as 'virga'. A thin layer of dry air sometimes finds its way into near the surface. Rain falls from low hanging clouds, but as the precipitation falls into that layer of dry air it evaporates.

Virga and precipitation shaft explained

Rain or any form of precipitation can be seen from a distance. This sight is usually known as a 'precipitation shaft'.
