Hey Westcoast, I think you may have seen noctilucent clouds. Very cool!
Check out this NASA article published yesterday. Apparently, they
have become visible earlier this year than ever previously detected.
At 34-37 secs into this video, the clouds seem to match the movement you describe.
It was not NLC's.
These are westcoast's words:
It spanned the entire width of the sky from horizon to horizon and was traveling from SE to NW.
NLC's are lit by the Sun, which at the time (before midnight) would have been well below the horizon in the north. For NLC's to be lit by the Sun from
"horizon to horizon" would be physically impossible since Earth would be in the way!
NLC's don't cross the entire sky - they are only seen above the horizon in the direction where the Sun is. Definitely not high up in the sky and close
to the opposite horizon (above which any clouds would certainly be in Earth's shadow) as westcoast is describing.
ETA diagram showing how NLC's are made visible by the Sun, and where in the sky they would appear:
As I said before, what westcoast photographed looks nothing like NLC's, and is more likely than not a normal cloud.

Don't know if you got far enough in the thread, but it was later reported that the Northern lights were visible from my area, and someone took a
picture of what I saw. This is why I now believe that we saw was the northern lights, perhaps interacting with the noctilucent clouds.
I am close to the coast, and as the 'stream' was brightest to the west, fading to the East, it would make sense that the aurora could have been
impacted by it.
