The fence rail that the gauge is attached to measured about 10.8" of snow but there was obviously much more than that on the ground. I went with the amount I measured in the grass for both new snow and total snow depth

9/8/2020 7:00 AM 0.36 T M T M Rain changing over to snow around observations time (06:45 is my best guess but it was not completely light to really tell). I had removed inner cylinder last night and this morning I poured the water from the outer cylinder into the inner cylinder using the funnel. Might have lost a tiny bit in the transfer due to splash (0.01?). Some slush mixed in but quickly melted. Still having a hard time believing what I'm seeing this morning, given how hot it's been.
9/9/2020 7:00 AM 1.07 5.6 M 6.0 M I lost part of the snow/ice as I was emptying gauge contents into a bowl so my measurement is is likely an underestimate. Also, the gauge had a rim of snow above the top of the orifice. Usually, I push my hand across and some goes in and some goes out. This time, it all went out so more underestimate from that. Couple big branches down in our yard due to heavy snow.
9/10/2020 6:50 AM 0.10 T M 1.0 M Probably had more than trace of new snow but it's all melted off my measuring area this morning. Total snow on ground is an average. Some places around trees are bare - other areas have 2+ inches.
