10/9/2017 7:00 AM 0.78 5.5 0.62 5.5 M Even though I took out the funnel and the inner cylinder, the snow capped over the gauge. I don't know how much moisture I lost because of the cap on the gauge. I took a core sample, but with the warm ground, a lot of the snow melted into the ground and was not collected in the core. There also was some wind, which meant that I didn't collect all the moisture before the snow capped over the gauge.

10/26/2017 7:00 AM 0.16 0.1 M T M Most of the moisture came down as rain, so a core is not practical. The wind is so strong that the gauge did not capture all the moisture.
10/27/2017 7:00 AM 0.13 1.5 M 1.0 M This storm came in with a good wind, so the gauge did not capture all the moisture. The snow was melting so fast yesterday that a core sample would not be useful.

2/19/2018 7:00 AM 0.27 7.0 M 7.0 M This is a much needed snow. Most of the time the snow came in horizontally with a 10-20 mph wind. The gauge probably caught less than half the moisture. I will take a core sample when it stops snowing. The 7 inches is an average from the front pasture.
2/20/2018 7:00 AM 0.09 4.0 M 5.0 0.66 The new snow amount is a measured amount, but could have been influenced by the wind, so take it with a grain of salt. The wind continued to blow 10-20 mph for most of this storm, so the gauge probably missed a lot of the moisture. If the core sample is accurate, and it is the best I can make it, then the gauge missed 0.30 inches of moisture during this storm.

I expect that the gauge missed some of the snow. At 7 PM after it had stopped snowing, I took a core sample. It was melting as soon as it started snowing, so probably a quarter of an inch had melted into the ground before I took the core sample.
