Weird Clouds

You wouldn't believe what I saw last Friday while at the local lake.  We were playing in the sand when my mom called me over to look at some strange looking clouds.  I said to her, "That's a wall cloud."  Turns out, it was not a wall cloud.  The kind of cloud I saw is often mistaken for a wall cloud.  The kind of cloud we saw was a shelf cloud.  A shelf cloud is different from a wall cloud because a shelf cloud comes before a storm and a wall cloud comes after a storm.  Here are some pictures taken by the fabulous photographer Michelle.
