7/9/2011	5:15 PM	0.51 inches of rain fell with the hail, rain lasted approx 45 minutes, causing minor street flooding. Hail started as rice size, increased to pea size after 5 minutes. Peas sustained for 10 minutes, enough to just coat the ground, then most hail ceased while heavy rain continued. rice sized fell again after a few minutes, lasting about 5 minutes. photo of hail pad available.	3/8"	1/4" Pea Size	Rice	Hard\|White Ice	20	3min	minor leaf damage	Intermittent	True	After rain	After smaller hail	30-40	256	0.3

7/19/2011	2:45 PM	Not present for this event. Some hail was left over in piles; stone measurements from remnant hail were taken ~3hrs after the event. Timing was estimate from radar, checked from my office in Denver. A second minor hail event occurred at ~5:30pm, as I was driving home, and within 1/4 mile of my house: Hard, white ice, mostly rice, a few peas, lasting only a minute or less. 0.86" of rain occurred from 6:30am to 6:00 pm with these hail events.
