7/26/2011 9:00 AM 0.24 T M M M A few large hailstones fell before the rain and small hail began, the largest I found was 7/8 of an inch. The stones were unusual in that rather then round, they were more flat like a disc. Not enough hail cause any damage, but they sure made a lot of noise bouncing off the roofs of mine and my neighbors houses. Continuous lightning, but mostly CC or IC with only an occasional CG strike.

7/25/2011 10:20 PM Large hail started before the rainfall. The number of hailstones was quite limited, with the largest I measured 7/8 of an inch. With the onset of rainfall the number of hailstones increased but dropped to only 1/4 inch in size. Heavy rain but I have not measured the amount at 10:50 p.m. as light rain continued. Quite the light show with continuous lightning, mostly CC and IC and only a few CG strikes. 7/8" Nickel Size 1/4" Pea Size NA Hard 8 2min no damage Continuous True Before rain Before smaller hail
