We don't get much in the way of thunderstorms in Ireland, and when one does arrive it's usually pretty mild. On this evening, however, I experienced a storm that seemed stronger than anything I'd encountered while living for 10 years in the American mid-west.
Once things calmed down enough to permit photography, I grabbed the camera and this is the result. I love the dark tones and the way the lightning has lit the underside of the clouds.
