Last Thursday evening, after a few days that were much too hot, there was a brief storm (at least I think there was, because there were really dark clouds forming, but I was inside playing DDR for a few hours, so I missed it completely). After the storm, the sky turned into a warm yellow color and was filled with mammatus clouds, which was a really really cool sight to see.
But even cooler was watching all the people that got outside of their houses and cars just to take a look at these clouds. It was like Pokemon Go, except instead of capturing a virtual monster, everyone wanted to capture a photo of the sky.
