I wanted to loosen up... Light rain showers from embedded altocumulus castellanus drifted across Singleton Lake all day. The dark bases of the castellanus provided the leaden gray colours I was looking for while the breaks between showers gave me the rosy and yellow bright parts of the skies. The clouds were aligned parallel to the deformation zone associated with a minor low crossing eastern Ontario. Notice that the clues to diagnose the weather pattern were all clearly written in the clouds... and thank you to those who comment... I read them all!
