Skywatch Friday:   Stratocumulus Undulatus

Stratocumulus undulatus clouds

Over Skagit Bay, stratocumulus undulatus clouds reveal wavy air motions in the atmosphere.  They can be a signal that rainy weather is on the way.  Or rainy weather is letting up.  Or both. 

Those who have followed this series may have noticed that all of the Skywatch photos here are the same scene shot from the same spot.  The two islands in the center of the photo are Skagit in front and Hope behind it.
