It was very humid yesterday and after sunset it got very cloudy and dark and eventually I heard thunder and then there was thunder and flashes of lightening. Wow. And it rained. A little. Not a lot where I am but maybe, I hope, other areas got more. And now it is back to extreme heat. Maybe by Saturday it will cool down a lot. It might actually be a nice weekend!
In the picture above, see the result of a heavy rain YEARS ago. Eight or nine YEARS ago, there was significant rainfall. Nothing like that since then. Welcome to the desert, or what WILL be a desert.
Everything's ephemeral. Remember that.
