In addition to just being beautiful one-of-a-kind panoramas in the sky, clouds can tell us so much about how energy and weather patterns flow around the globe. Today, we'll talk about how clouds form, the three main types (cirrus, status, and cumulus), explain how and why we get rain, and end with a discussion on humidity and how high humidity can feel hot and sticky on a warm day but comfortable on a cold day. So join us and countless people throughout history and look up -- at the clouds!
