Another good example of a scud cloud today. Scud clouds (also called fractus) form beneath rain showers or thunderstorms when warm, humid air is drawn upward into the storm. They often appear ragged and can rise rapidly. A scud cloud like this can exhibit some spinning or twisting because... of turbulent air or localized wind shear. This rotation is usually shallow, disorganized, and does not indicate a tornado is forming. Remember, motion alone doesn’t make a tornado. Rotation alone doesn’t make a tornado. You need persistent, organized rotation associated with the storm’s updraft before tornado development becomes a concern. Video from Dillyn Chanceyshow more
