RMK: Might have reported Cu as St on another day, but some
vertical development is clearly evident, and there's been no "bad
weather" for 10hrs. Surprised at excellence of visibility.

RMK: A few gleams of sunshine around 0930z, but precious little
since then. Dense Ac layer with rather mammatiform base.
