8/23/2013 6:00 AM 1.36 M M M M Value is from my Davis Gauge; Coco gauge reported 1.13 ". Severe T-storm around 5:30 Pm on the 22nd. Abundant quarter to golf ball size hail. Visibly observed bouncing out of gauge. Given bigger collector bucket on Davis gauge, more probably stayed in. Both gauges probably have undercall relative to actual total precipitation
