'''Altocumulus''' clouds are small, puffy-shaped clouds that usually appear in regularly-spaced groups at [[altitude]]s of 8,000 to 20,000 feet.  They may occur in a layer of atmospheric [[instability]], and generally have a banded or rippled appearance.  When observed in the morning during the spring or summer months, indicate a very high probability of precipitation in the afternoon.
