Crepuscular/Anticrepuscular Rays and Supercell Storm Formation        


These photos were taken on July 20, 2014 of a beautiful cloud formation and subsequent crepuscular rays and anticrepuscular rays.  The cloud formation did develop into a Supercell thunderstorm based on the weather warnings from Environment Canada and the characteristics of the thundercloud over time.  I have made comments on each photo to try to explain exactly what was happening. 

The first photos were taken as the sun set and produced beautiful rays that spanned the whole sky.  The fourth image is a full sky image taken with a Canon 5D MKII camera and a Sigma 8mm fisheye lens.  As the night progressed the thundercloud grew to enormous proportions and developed into a Supercell.  The lightning photo was taken 2 hours and 16 minutes after the first photo in this series and the storm cloud was around 50 to 80 km away according to the Doppler radar images on Environment Canada's website.  The lightning blast was crazy, I recorded about 30 other lightning blasts in the same period but this one was blinding.  The power of that megablast must  have been astounding.  I have also included a close-up of that lightning megablast that I enhanced (basically adjusted the levels with PhotoShop) to show the amazingly powerful central lightning stroke that lit up the whole storm.
