August 30, 2013 Severe Weather Event

 

Lightning

   One of the noteworthy aspects of this event was the amount of lightning in the storms.  While not all storms were severe, the frequency of the lightning certainly made them hazardous to outdoor goers on the evening of August 30th.  Below is image of cloud-to-ground lightning strikes within a one hour time frame.  There were nearly 4,000 strikes in that time!
