The sky this morning was blue and sunny except for fog on the East Ridge. Two hours later the storm clouds were rolling in and, soon after, came the hail and then snow. Here’s a photo of the storm clouds with a little sun still hitting the mountains. After that is a sped up video of the storm clouds. Notice how some of the clouds are moving left while others are moving right. The movie is sped up to 500%.
The video was taken hand-held with my little point and shoot camera, so I apologize for the shakiness, which is only accentuated by being sped up 500%.
