The thunderstorms themselves were pretty typical, they came with heavy rain, small hail and vivid close lightning strikes at my location. There was really no wind to speak of at all until the storms got near Near the end of the rain shelf behind the strongest cells, then strong east winds developed and gusted for about an hour. There were power outages, I believe was from lightning, which took power out to downtown Clayton for an hour to many popular business in town.
