McKloud Tempest, designed by Jessica Slater and Apostrophic Labs in 2001, is a free cartoon display font shaped like swollen cloud banks. The rounded lobes and tucked black shadowing give the lettering a stormy puffed-up rhythm, so the whole design reads more like weather forms than ordinary display type.
That makes it a natural choice for comic titles, kids' posters, party invitations, game graphics, and playful packaging where the cloudy silhouette can carry the theme. Short headlines and logos get the most from it, especially in projects that want a soft, blustery look without switching to literal illustration.
