This video is sped up 16 times, compressing over 15 minutes of real time into a little less than 1 minute. It shows the parent storm movement from southwest to northeast (quartering toward the right side of the frame) while the shelf cloud scoots from northwest to southeast (toward the left side of the frame), being pushed in that direction by the outflow from the storm. It also shows the upward motion of scud into the base of the cloud. No rotation, and nothing severe, but it was cool to watch as it approached. Meanwhile, I missed the convective action today as I was out of town. Oops!
