Up, Up and Away

Seen here from Fay Clark Park in Hiawatha, Iowa, cumulus towers some 50 miles distant were rising into the fading sunlight on Sunday, August 2, 2015. Images look south and southeast. In the top image (8:02 pm CDT), the towers are nearly vertical. In the middle image (8:06 pm) they begin to interact with stronger winds aloft. Some of the structures are bent nearly horizontally in the bottom image (8:14 pm). Severe weather was occurring behind the towers, over 100 miles away near the Iowa/Missouri border.
