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 spanned the entire width of the sky from horizon to horizon and was traveling from SE to NW.
