Yeah, I personally have never found the weather icons to be very useful for many of the same reasons already outlined in this long sub-thread. If that's because I didn't "understand" them properly, well then that's a signal of UX failure imo. I personally think that if users have to think too hard about what an icon (or status indicator) means, then something's not right with it and you need some other visualization for conveying whatever message it is you're trying to be convey. For me, the weather icons have never passed that test because, at this stage, I've heard multiple people on different occasions say that they find them confusing. That, to me, tells me that they don't work and a different visualization is needed.
