Viewed from high atop the National Weather Center, the sunset in the west was pretty, as they often are in these parts. One easily could have gotten fixated on that, and missed this even more brilliant and peculiar formation lighting up the eastern sky! A ragged midlevel convective tower (altocumulus castellanus) still had enough strength to force some lift through stable layers near its base, creasing the striated effect. I especially enjoyed the tonal and textural contrast between the flame-orange tower, a muted gray-orange of unrelated anvil cloud above, and background blues with anticrepuscular rays in the distance.
