comments: No visible hail on ground after TS passed, but obvious as they fell and the sound on the roof and other objects obvious, but the hail was tiny -- mostly rice size with some pea-- when inspecting the hailpad. Saw some dime size as they fell, but melted before I could observe outdoors. Hail which was visible fell as the heavy rain started to fall, 1:54 pm. My neighbors 1/10 mi north of me reported larger stones.

Notes: Rain started at 1:30pm and got heavy, (and some thunder during most of the rainfall); and then hail at 2pm to 2:08pm, with the heavy rain. I could not see thru my front glass door, which faces east, because the rain was hitting it (and eventually as mixed with some hail). When I looked out my back door the rain was at about a 30 degree angle; and 'groups' of rain swirling around in different directions. It stopped briefly; and rain restarted at 2:17pm and last maybe another 1/2 hour. -- my property dirt was bald with the rain washing some of it away, but it was not muddy (it ran downhill). my small stream had about 4" of water running rapidly thru it (about 10-12" wide).

comments: Rain started at 1:30pm and got heavy, and then hail at 2pm to 2:08pm, with the heavy rain. I could not see thru my front glass door, which faces east. When I looked out my back door the rain was at an angle and swirling around in different directions. So I didnt judge the distance between the hail pieces, but what I saw, it was maybe 10" apart(?) and 1/2" in size. It stopped briefly and rain restarted at 2:17pm and last maybe another 1/2 hour.
