Churning Clouds After Volatile Day

Churning storm clouds pass overhead in this view looking southeast from the parking lot at Noelridge Christian Church in Cedar Rapids, Iowa at 12:25 AM on June 18, 2010. This line of storms was a southern extension of a system that produced a very large tornado outbreak in southern Minnesota (around the Albert Lea area) hours earlier. The clouds are illuminated by the ambient light below. This capture was a 10-second exposure at f/6.3, 18mm focal length and an ISO rating of 200.
