I can also confirm rain. I was in New Atlantis today. At the start of doing my errands, it was a typically sunny day. A few hours later, the weather changed to rain (as with Cyberpunk 2077, there seems to be a behind-the-scenes dice roll to determine the weather every time a new instance loads). I was happy to see this because I thought New Atlantis was only going to be a perfectly sunny place. The only thing I didn't care for is how SF produces a rainy day in the same way as NMS: you might see a gray sky and raindrops, but the lighting remains sunny. You can see that here:

That's a strong shadow for such a cloudy day. Stuff like that annoys me.
I stole my first ship from raiders. While doing a planetside survey, I came across this landed ship and shot my way aboard. Now it's mine! Here it is landing at a LIST homestead.
