Check these marvelous shots taken near Michigan City High School of mammatus
clouds which appear to hang from the underside of an anvil-shaped towering cumulus
clouds. Tama Pickford was good enough to send these along and asks in her
accompanying e-mail is these are "upside down" clouds. It certainly looks that way,
doesn't it? Mammatus clouds DO have the appearance of hanging from a cloud deck
above so Tama's description is a good one. This formation occurred as a powerful cold
front roared across the area--a development which sent temperatures tumbling and
produced the first official flakes of snow at both Midway and O'Hare in Chicago Sunday
afternoon and evening. Thanks Tama for the great shots!
