We had a sunderstorm that lasted for about half an hour and the mountains in the distance started to look like Mordor.

A thunderstorm where the sun stays out the whole time.
Tim: DUDE! It was sunny the whole time it was storming today. There was lightning and everything!

Chase: We live in Virginia, man; we always have sunderstorms.
