April 9, 2011 Mapleton, IA Tornadic Supercell
Last Updated on Wednesday, 13 April 2011 21:41 Written by Roger Hill
April 9th took us to the warm front in western/northwestern Iowa. A supercell developed on the southern flank of a cluster of storms, and became the storm of the day. Very good shear, moisture and instability would allow this beast to spin for hours! We witnessed 12 tornadoes from this monster, with many strong tornadoes occuring after dark. Photography is tricky when you don't get a ton of lightning, thus a few of the images are a bit blurring caused by long exposures at high ISO.
