Promise

Spotted this rainbow when I was out a little earlier this afternoon. What you can't see in this photo are the ominous dark clouds on the right, coming through on a cold front that's supposed to bring blizzard conditions over the next few days. This was about 4.15pm, and now, an hour and a half later, it's pitch black outside with sleety flurries, and the wind is making it feel quite a few degrees lower than the actual temperature.

This rainbow is certainly not promising the end of the rain!
