Kevin Sheely relays these pictures to us of mammatus clouds—the bumpy clouds visible here on the underside of a cumulonimbus (thunderhead cloud) anvil—taken this past Wednesday, May 6. And check out Kevin’s rainbow shots with the same storm. All were taken off I-35 in Osceola, Iowa. GREAT SHOTS, Kevin! Thanks for sharing them with us!
