This video is from Beacon, NY's July 4th fireworks. Fifteen minutes prior to the first launch, a thunderstorm rolled in. For 10 minutes we had torrential rain accompanied by a few cloud to ground lightning strikes. The rain abated and the fireworks show began but Monther Nature lit up the sky with her own show. For nearly two hours we watched sprawling cloud-cloud bursts. This video captured a bit of the amazing show.
