If temperature records don’t fall over the next few days, it will be close enough so that you probably won’t be able to tell the difference. A strong ridge of high pressure has planted itself right over the Great Basin and will stay put into the weekend. Mostly sunny skies will accompany high temperatures in the mid to upper 90s through Saturday, after which things will slowly cool back into the low 90s on Sunday, and then to the mid-80s by the middle of next week. At this time there isn’t a real chance of seeing any showers out of the pattern.
So why are rainbows curved? First of all, it’s because raindrops are round. And you aren’t seeing a “projection” or “beam” of light across the sky. Instead, what you see are individual raindrops of different colors… the color being dependent on where you are standing. And the “red” raindrop you are seeing will be a different color to someone standing apart from you. It’s also why you will never find the pot of gold at the end of the rainbow, since the rainbow “moves” as you do.
