I dont think this really is severe weather, but did not see any other topics to post it under. Sunday evening while flying back to Washington from my much needed and way too short vacation in Indiana, while flying over Montana, I noticed something that I had not seen before. (I know it was Montana because I take my laptop and use GPS tracking to see where the plane is so I know how much longer it will be). The pilot started making a few changes in direction, and before long, I could tell he was maneuvering around some thunderstorm clouds. I have seen storm clouds before from the top while in an airplane, but what was different about this storm was what was shooting up from the clouds....not down. What I saw was quick flashes of light that extended extremely high into the sky above the storm clouds that looked like a red jelly fish with blue tentacles hanging below. They lasted slightly longer than a normal lightning bolt. Does lightning shoot up instead of down to the ground? If so, does anyone know what causes it to look like a red and blue jelly fish instead of just a normal bolt of lightning? I am completely stumped and can not find anything online about lightning that flashes up. Any ideas?
