A Cloud Mystery

Cloud spotting may appear a strange hobby.

In truth, I’m trying to develop photography as a hobby (I’ve a steep learning curve).  I was shopping Saturday and the sky to the north was blue.  To the south and east, it was a very different look.  I know the names of cloud formations, but I can’t place the formations with the names unless I look them up or ask you what I’m seeing.  What’s the cause of this formation?  What does it betoken?  Please email me answers at bill.colley@townsquaremedia.com.
