A cool-down today from a warm week–highs in the low 80s the last couple days, in the low 60s today. A little bit of a breeze from the coast. And then in the afternoon, clouds. A species of altocumulus, I think. (Which species? Well, that looks like it might be complicated to work say.) I went up on the house to get a clear shot to the west over the houses across the street. I observed the clouds and also the very pronounced undulations of our 91-year-old rooftop.
