I was trying to see how much you could surmise merely from the pictures!

Both were taken in Yellowstone, September 2010, on the same day. The two pictures of the same cloud formation were taken shortly after a 20 minute long snow shower, which came towards the end of a rather hot and sunny day.

The temperature dropped from mid 20s to about 5 degrees shortly before it started snowing.
