During the late evening hours of June 12th, a series of thunderstorms slowly moved through central Indiana from the north.  An outflow boundary in eastern Marion county led to additional thunderstorm growth north of Indianapolis that eventually would bring damaging winds and large hail to portions of Indianapolis and western Hancock County. Slow storm motions and backbuilding led to some areas to receive up to 3 inches of rain which caused isolated flash flooding.  Over 20,000 power outages were caused by the thunderstorms with some noted to be from lightning strikes and others from tree and power pole damage.
