6/22/2010 8:00 AM 0.40 M M M M It rained pretty heavily, and steadily, from about 3:00 to 3:30. There was hail mixed in during most of the rain; spongy at first and then a little harder towards the end of the storm (the big stones were very spongy with the smaller stones much harder/bouncy). The largest stones were about 1.2 cm in diameter, the rest were about 5mm in diameter.
