Severe Weather Closing In

This view of the southern flank of an approaching supercell was taken around 6:00 PM, Saturday, April 9, 2011, on Cherry Avenue, about .1 mile south of Highway 175 and about 2.8 miles west of the Onawa, Iowa exit on Interstate 29. The severe weather would begin to produce tornadoes northeast of this position about an hour later. Observing the clouds at lower left is Iowa State meteorology student and storm chaser Bryce Link.
