Extended period of lightning
« on: July 25, 2017, 02:48:59 PM »
Starting Sunday night about 11 PM and not ending until 5 AM Monday. It always amazes us that, at night a lightning storm will light up the night sky when the storm is still 80 or 90 miles away from us. We are at 2200' elevation but on 3 sides we have a 4000+ mountain within a few miles.

The weather camera also functions as a driveway monitor so it takes photos when it senses a change in light in the bottom 1/3 of the frame. It was really busy Monday morning. In this image

what is the trail from the tip of the lightning to the ground ? Was it really there or is it created by the camera ?

There is a mp4 file here . It is interesting how the shadows cast by the lightning change as it moves from behind the camera, to right over the top, to the front.

It could be a stepped leader (or maybe a dart leader?). Where there subsequent frames where this was illuminated fully by the main strike?

No there was not another frame. The camera takes 2 pictures on each event, and then it waits 60 seconds before it will trigger again. That one was the 2nd of the series. This was the 1st of the 2:
