9/15/2010 7:00 AM T M M M M Three fairly intense showers around 12:05, 12:25, and 12:34 AM. Each one lasted less than a minute, with some sprinkles between. The sky appeared clear at 12:15 AM, but radar showed > 40 dBZ with at least two of the showers. Pavement was completely wetted. The official gauge's meniscus was just a sliver below 0.01", but a very small bee was floating in the water, so a trace seems reasonable. My tipping bucket did not tip. What a bizarre event.
