7/14/2018 7:00 AM 0.43 M M M M Of the amount reported, 0.41" of precipitation came in 1/2hour as rain and some hail the size of a grain of rice or less. System producing that heavy rain was a thunderstorm out of the north.

7/17/2018 7:20 PM I don't have a hail pad, as I have had a hard time finding the right styrofoam to make it. The hail swithed between rice and pea-sized and sometimes did both at once. There was quite a bit on the ground even after the hail fell. 1/4" Pea Size Rice Rice Mixed|White Ice 30 3min no damage Intermittent True After rain After smaller hail vertical
