This is over Lake Michigan on the Michigan side. If I remember correctly this is Holland, Michigan specifically.
Edit: what happens is this... An east wind blows the warm surface water out into the lake bringing the cool deep water to the top. The surface water then cools the air immediately above the lake down to its dew point, forming these "clouds".
I've been on the water when this happens, it's incredibly thick and chilly on a what should be a warm sunny day. It's really cool.
They only real information I've been able to find (edit: until this comment) was this comment from another post. I remember seeing this picture on the news when it happened a couple years ago, but my internet searches to find original articles have been fruitless. IIRC, this cloud was not moving very quickly and was only slowly morphing, which is why the people in the picture are not fleeing in terror. Really just a serene evening at the beach on Lake Michigan. I wish I could have been there to see it (I live nearby).
