On certain overcast mornings, there is a brief period of glowing, atmospheric blue. This only happens sometimes, and I don’t know what causes it, but it’s a rare treat. You have to catch it at just the right time, because the perfect level of brightness only lasts for a couple of minutes before it starts to get too bright. The clouds really made the scene this morning, these great ridges in the sky, almost resembling the undulating waves below.
