Balls of lght in a snowstorm.

There was the beginning of a huge snowstorm outside and I was inside by the fire.  My mom and I were listening to the radio when suddenly the DJ made that annonuncement that people in and around Charlotte, NC (30 miles away) were seeing balls of light flying through the air.  I immediately drove over to my best friend's house and we watched the sky light up with brilliant flashes of light.  I don't know how to describe them except to say they definitely weren't lightning.  Later that night the government let out a release saying that it was transistors blowing up (all at the same time, during a 50 mile radius; mind you I could drive in this weather).  The next day they said that it was heat lightning (in the snow) caused by the strange change in weather (it was hot the week before).
So many people saw it, I figured somebody should report it.
One of two reports from same witness.  PD
