Best advice is to wake up Early! The clouds almost always seem lower at ~7:30 AM here. Keep in mind the humidity will most likely be higher and video transmission range will suffer especially if you use 2.4 or 5.8 video.
I like to check this website to find out where the cloud base is going to be...it's fairly accurate. Just swap in your local airport code.
Have fun! (These were at 1200-1400ft AGL)
