What is dry lightning?

"Dry lightning" originates from thunderstorms, but the rain in these thunderstorms is not touching the ground.

Erica's Answer:

When rain falls from a cloud but evaporates before reaching the ground, it is called "virga".

Dry thunderstorms happen frequently in the desert southwest. The rain from the thunderstorm falls down into a pocket of very dry air, and all the rain evaporates. However, the lightning can still hit the ground.
