A lightning storm we had the other day.
Great light show, but no rain.
I think you;ll get some good pics today, Thunderstorms predicted on the east coast
nice 
Another one, I get heaps of pics with the motion detection but most of them are just a white out.
I have a gallery of lightning images captured by my skycam. The large images were captured with an Axis 211 netcam’s built-in motion detection. The small images were captured with a Samsung analog camera and Image Salsa. http://tobaccovilleweather.com/LightningGallery.htm.
You have some spectacular photos in there.
I just supplied a bit of technology. Mother Nature provided the light show. The full sized images can be viewed by clicking on the thumbnails.
