comments: Do not have a pad. Hail was hitting the ground with in 1 inch of each other. It came down heavy and melted quickly with some intermittent build up on the grass.
Hail started about 1 minute before rain. Then very heavy rain, totaling .75 inches in 18 minutes by end of storm
At 6:59 lots of thunder and heavy rain with the hail. At 7:01 much smaller hail, about 1/16 inch diameter.
The rain stopped at 7:08. There was a beautiful rainbow to the east!!
