I was on a tiny bog lake miles from anywhere. First there were no clouds. Then the clouds looked beautiful, as in the photo. Then they looked ominous. One flash of lightning was enough to send us off the lake for half an hour, waiting out a small storm. Then the sun came out again.
There were little storms like that all afternoon, the kind where you can see sunshine and blue sky while standing in the midst of a downpour of rain and hail. Things have settled down for the evening, at least I think.
