The featured animated GIF is derived from multi-channel GOES-16 (GOES East) imagery attempting to show a "true color" depiction of what you would see from space. This loop is from Monday and shows the large cloud shield in the shape of a comma with the comma head showing a discernible rotation over Iowa. This system was 'stacked', which means the surface low pressure is vertically below the upper troposphere low pressure center. This type of cloud formation is common with mature and large storm systems.
