Over the years, I have gotten better about being able to judge the weather by looking at the sky. Not perfect yet, but better.
If I had seen clouds gathering like this in Minnesota, I would have thought for sure that a storm was gathering.
But here, mostly they are just interesting and pretty to look at. That is not say that they can't quickly develop into rain clouds and dump a deluge on you before you know what hit you.
Others, like these, are much easier to read.
A rainbow means very little. Just that the light is just right. It does not necessarily signal the end of a storm.
And then there are these:
In the old days, I would have been concerned about them. I have since learned that the darkness they contain is merely a shadow, not rain at all.
And then, again, some clouds are just plain pretty to look at.
