Just search on Coastwatch (NOAA sats) and Terrafin. Terrafin has a free image of the Oregon coast below about the 46th parallel. Coastwatch is free also, raw unprocessed sat. data so if it's cloudy no image. Page back to previous shots and you can see what it was bafore the clouds rolled in.
Read this post for some discussion on fog/clouds temps and manipulating the coastwatch shots.
