The great thing about eclipses is it really doesn't matter where you view it from, so long as you're outside. City, country, hilltop, valley, doesn't matter. Light pollution really doesn't make a difference, nor normal amounts of smog, though fog would.

We've got partially cloudy for the start here, but clearing up during totality. And it depends on what they mean by "partially cloudy" - thick clouds with holes between them is workable, if the holes come at the right times; thin clouds covering the whole sky (i.e., a thick haze) is less good usually.
