Gravity Wave Clouds over Wilmington Delaware yesterday

There were these strange cloud formations over Wilmington, Delaware yesterday around 5pm. There looked like the clouds were large waves with light and dark areas that looked like a frozen undulation across the sky. I recalled that there is a cloud effect called gravity waves and I tried to get a picture or two with my cell phone. Unfortunately the pictures don't give the full effect. You could see many bands of dark and light depending on the direction you looked and the waves stretched from horizon to horizon, it was very eerie. I took two pictures pointed to be next to each other to try to give a sense of the scale.

Looking slightly Right (approx north west)

This youtube video shows an time-lapse example of gravity waves over Toma, Iowa that gives the full effect.

I didn't have the time or equipment to try to capture that much time-lapse motion of our gravity waves clouds yesterday. So many natural phenomena, so little time.
