Weird variety of clouds this afternoon on my way home at at about 3:45. Turreted cumulus (castenullus??) to the west running along in a long line, with quite a bit of height. To the east a kind of wall cloud. Blue skies, cumulus and altocumulus inbetween with some very high level cloud, quite crystal like reflecting red and green light. Sun has now setted and temp is 7.5*C
