Okay, this was really cool. Sitting at my desk just now, I noted that the sky was dark but the ground was dry. Suddenly I heard what sounded like a truckload of gravel being poured on the roof. I looked out and some of the most amazingly big raindrops I had ever seen were pounding down. Just like that the ground went from dry to totally covered in water. Really: about three seconds. It was almost like some celestial bucket had dropped a solid sheet of water on the ground. There were only a couple of seconds where I could see the drops on the pavement before it was all wet. Really impressive.
And now, two minutes later, it’s completely stopped. Not the kind of thing I’d like to be caught in a parking lot during! I don’t think I’ve ever seen a true “cloudburst”, but if this doesn’t qualify, nothing does. Crazy!
