4 W of Tecumseh, OK; 15 Apr 2013
Direction of view is SE. Image interval is irregular at 43 images (6 minutes from first to last). Time lapse exposure varies due to differing brightness of lightning and variable aperture durations. The view encompasses a rapidly left- (NE-)moving, elevated thunderstorm in front of a separate, right-moving supercell that is mostly hidden from view. Because the images were taken for lightning capture, the interval is irregular; still, you can get a good idea of the evolution of the convective turrets.
