10/24/2019 7:00 AM 0.56 5.0 0.56 5.0 0.56 My total precip. measured in the gauge and on my ground measuring surface just did happen to come out exactly the same, 0.56". In gauge: when checked at 7:30 p.m. there was 0.02" of liquid water in the tube, that fell as rain and melting snow, + more snow already accumulating in the funnel (removed funnel & tube then); the rest all collected as snow, 0.02"+0.54" = 0.56" total precip. On the surface at 7 am, 0.54" SWE as snow + a thin layer of ice on the bottom = 0.02" when scraped off and melted, total = 0.54 + 0.02 = 0.56".

10/27/2019 7:00 AM 0.08 0.1 0.03 1.0 0.26 Of the 0.08" total water content in the gauge, 0.07" was ice and crusty snow on the inside of the funnel, 0.01" was loose snow that collected in the bottom of the tube. On my measuring surface, 0.02" water content was in 0.1" depth of loose snow on the top, and 0.01" water content was in a layer of ice beneath. Total snow on the ground was mostly old snow still left from the previous snowfall.

I was going to just report total old snow as "trace", but I decided to try to be more scientific. About 1/3 of the site has between about 1 to 2 inches of snow on it, the rest is bare. Taking 1.5 inches as the average for 1/3 of the yard, overall average is (1.5 x 1/3 + 0 x 2/3) = 0.5 inches, which I'm reporting. A snow core taken where the depth is 1.5 inches contains 0.39 inches of water, so, the overall averaged water content is 0.39/3 = 0.13, which I'm likewise reporting.

7/28/2020 3:00 PM Just a small amount of pea-size hail was mixed with the rain during a hard rainstorm, accompanied by strong wind. Storm began with very strong wind and hard rain, then I noticed a few small hailstones mixed with it. My report of the time of the storm is just a guess, I did not record it and did not even check a clock, it could as well have been 4 p.m. as 3 p.m. 1/4" Pea Size 1/4" Pea Size 1/4" Pea Size 5 3min no damage Intermittent True After rain 30-40
