Watch the lightning change from a pinkish glow to bluish - this happened twice that night - any explanations? This lightning show represents part of the most incredible and most frequent lightning sparked show I have ever witnessed filmed overhead - straight up. It was as if the clouds were talking to each other - lightning from one thunder head to another! I recall we were simply too tired to go on filming this electrified mesoconvective system and headed back to the hotel after 1:30am!
