I've used every emote in every weather at every hour of the day and got nada. If I had known what that rainbow might mean when I saw it yesterday, I would have booked it back to the goobbue and prayed like Mother Teresa. There are only two possibilities at this point - its the rainbow, or its the heretofore unseen "Rain" weather.

I believe the rainbow appears in Fair weather following Showers during the 8am weather change, since I believe that's when I took the picture, and I have since tried it in Clear at 8am after Showers and no rainbow.
