An incredible time-lapse sequence of the Fort Cobb, OK supercell from April 3, 2003. This footage has been included in a number of tornado/weather documentaries. Although the storm never did produce a funnel or tornado, it did produce grapefruit sized hail!

FYI - the song is “La Femme D’Argent” by the French group Air.
