A "hole in the sky" over Tinley Park, Illinois Tuesday morning

|

A break in this morning's mid-level cloud deck reveals another cloud deck above. This makes for a very interesting photograph. The lower of the two cloud decks is composed of a layer of altocumulus clouds while altostratus clouds appear above. Darren Meyers took this photo while waiting with his son and daughter for his their school bus and was good enough to share it with us. He calls the phenomenon a "hole in the sky" which strikes me as an apt description. Many thanks, Darren, for sharing this with us.
