Drive To A Wall Cloud

With an SPC slight risk for severe weather designated for southeast Iowa on Saturday, July 12, 2014. I set out with my daughter in tow south from Cedar Rapids a little after 5:30 PM. Our efforts were rewarded: Just south of Cedar Rapids along Interstate 380 a cell began to explode into the atmosphere and soon became severe warned. Echo tops would reach 45-50,000 feet. The cell would form a wall cloud with beautiful structure. The top image was captured at 6:25 PM near the North Liberty Iowa exit. The middle image was shot about a minute later and shows the storm with a tail cloud feeding into it. The bottom image was captured at 6:33 PM from the off ramp of US Highway 218 to Highway 1 south of the I-80 interchange. The wall cloud and tail cloud are evident. I fully expected a tornado to form from this mildly rotating turbulent structure, but it did not happen.
