1/1/0001	12:00 AM	It was around 2:00 or 2:20 am. The hail was still there in the morning. The pattern was lightning, thunder, hail, sounding like it was mixed with rain, blown into the windows somewhat horizontally rather than down to the ground. There was a dusting of snow in the morning too.	Rice	Rice	Rice	Soft\|Clear Ice\|White Ice			no damage	Intermittent	False
7/10/2011	2:19 PM	The hail melted quickly. Then we had another hail storm at 5:37 pm with white, soft hail that was rice sized. This only lasted one minute and also melted quickly. So there were 2 hail incidents and 3 different episodes of thunder, lightning and rain.	1/4" Pea Size	1/4" Pea Size	Rice	Soft\|White Ice	2	1min	minor leaf damage	Continuous	True	After rain	Same time as smaller hail	30-40
