8/11/2018 8:00 AM 1.37 M M M M Heavy rain and hail began at 4:46 pm yesterday. August 11, 2018. The heaviest rain (and hail) stopped at 4:54 pm, but the rain was still quite heavy. At 5:30 pm there was still light rain that slowly tapered off. Rain had fully stopped by 5:50 pm. Winds caused the rain to fall at 30 to 45 degrees. The wind and the hail caused our two rain gauges to record significantly different values. The open gauge (for hail) read 1.37" for rain and melted hail; and this is the official value we report. The gauge with the funnel and inner cylinder read 1.10"; but we believe that not all the rain and hail went through the funnel. We also filed a separate hail report.

8/6/2018 1:30 PM Very few hailstones fell altogether. Moreover, they melted almost immediately after hitting the ground. 1/4" Pea Size 1/4" Pea Size 1/4" Pea Size Soft|White Ice 10 1min no damage Intermittent True Same time as rain Same time as smaller hail 10-20
8/10/2018 4:46 PM The wind caused the hail to pile up in corners; therefore it wasn't possible to measure either distance between hailstones or their depth. We estimate that a uniform distribution would have been no more than one hailstone deep and not full coverage. The hail melted soon after hitting the ground. 1/4" Pea Size 1/4" Pea Size Rice White Ice 8 1min minor leaf damage Continuous True Same time as rain Same time as smaller hail 30-40
