Rainbow embers

The day began with a storm, which melted into heat, which remained heat until a new fleet of silver clouds pushed in, and then there was storm again, the skirts of trees immodestly blowing.  We were celebrating my son's birthday at a restaurant when the rain stopped, and when I looked outside, a rainbow was arching over the telephone wires.  A half hour later, the sky was this, lit from below, I suspect, by rainbow embers.
