Severe thunderstorms in the Denver Metropolitan area produced very heavy rain, large hail and damaging winds.  The strong winds toppled a few trees and the heavy rain caused street flooding and minor flash flooding.  Several cars were stranded at the intersection of Santa Fe Drive and Oxford, and near Broadway and U.S. Highway 285.  A 16-yr old teenager was seriously injured when he tried to retrieve a ball along the banks of West Toll Gate Creek.  He was pulled from the swollen creek and died several days later.  Hail up to quarter size was also reported around the area.  The thunderstorms also produced frequent lightning.  One strike sparked a fire at Aspen Academy, a private school in Greenwood Village.  Most of the damage was confined to the roof and attic.
