The Lightening storm Started around 10 pm and Ended at 1:45 AM.
Th final strike Struck the hill side aobut 5 miles from us. there was little thunder heard as the storm was trapped between the foot hills and Mount St Helens, So the Sound was muffled most of the time. It was not until it ended that we got some nice rumbles of thunder and one final thunder clap that sounded like a distant tank firing its canons.
It was a magnificent display.
