Twin Storm Cells

Although not severe-warned themselves, the two thunderstorm cells in the top image were part of a line of storms that fired up on Memorial Day, Monday afternoon, May 28, 2012 from just northeast of Ottumwa, Iowa all the way up into southwest Wiscconsin. The storm cells can also be seen in the NWS-Quad Cities radar image (circled) at bottom. The top photo looks SSE from the new Bowman Meadows housing development site in Marion, Iowa around 5:29 PM. The cells were located about 55 miles away from the camera in northern Louisa County and were about 20 miles apart.
