    Early this morning the sky was clear but shortly before 9am contrails started persisting in places:

    All the contrails started appearing along one line roughly parallel to my northwest-facing window. Soon the sky was well covered with a grid of contrails while beyond the line, to the west, stayed clear:

    The boundary between clear sky and contrails is gradually getting further away to the west.
