If there is only low cloud along the coast or over the ranges then from 75km inland it will be fine. eg.. if the cloud height is 2000m, then with the sun angle of 13 degrees, you'd need to be more than 8km further west for the sun to clear the cloud.
if there are cumulus clouds reaching say 5000m (could easily be higher some days, but not so often in the morning) then you need to be 20km west of them. still generally ok if the clouds are only along the coast/ranges.
often though there is cloud much further inland as well. If you look at the high resolution visible satellite images that houghy has posted, you can actually see the shadow of the cloud on the ground.. as long as you're not in that shadow you're fine.
but we won't have high res satellite images to use during the night before the eclipse.. only low res infrared images.
