So it's been going back and forth between grey and blue skies for the better part of the day. Just a little while ago, when things started to look particularly ominous, I set up my time-lapse machine to see if I could catch the transition from plain old grey to thunderstorm grey.
While I didn't manage to capture any lightning, you can see the clouds racing around as well as evidence of the downpour.
And while this video is definitely not perfect, I'm pretty confident that it is one of my better time-lapse clips of clouds. Hopefully my past efforts won't deter you from watching this one.
