Gusty Invasion

A shelf cloud, the leading edge of a powerful gust front, surges in from the northwest (left) as seen from Echo Hill Presbyterian Church in Marion, Iowa around 7:40 PM, Wednesday, June 8, 2011. This storm proved to be very severe, with straight line winds reaching 60-80 mph, uprooting some trees and breaking large branches off others. Golf ball size hail was also reported in the area about an hour later.
