These clouds are of medium altitude, about 8000-20,000 ft (2400-6100 m). A middle cloud, usually white or gray, often occurs in layers or patches with wavy, rounded masses or rolls. Altocumuli often are seen preceding a cold front, and their presence on a warm, humid summer morning frequently signals thunderheads later in the day. image:skyAltocumulusClouds.jpg|Altocumulus in a clear mackerel pattern Image:Mackerelskylincolnshire.jpg|Mackerel sky over Lincolnshire, UK.
