Yesterday evening I noticed a squall forming over the butte to the south of us. Here's how it developed. I photographed it from different directions as it slowly moved our way.
The setting sun.
The squall moved so slowly that it didn't hit us until dark - and by then the temperature had dropped and the rain turned to snow.
Still, it was a pretty way to end the evening.
Oh, and just for kicks - this was the sun during the midst of a snow squall earlier in the day. Don took this one.
