Ever heard of Virga?


Have you ever wondered why sometimes we see rain on the radar, but it is not raining? This could be caused by a weather phenomenon called virga. Virga occurs when precipitation falls from a cloud but evaporates before reaching the ground. It typically appears as wispy streaks or bands of precipitation that hang from the cloud but do not reach the Earth’s surface.
