10/9/2017 10:30 AM 0.33 0.0 0.00 0.0 0.00 I checked the gauge at 10:30 but no rain fell between early in the morning and 10:30. So the 0.33" figure captures only the previous precipitation event -- we can call it the rain of 10/8. Interestingly, it is just starting to sprinkle here in Old Town right now. at 10:40.

12/26/2017 2:00 PM M 11.8 1.31 20.5 4.73 The gauge was not on the post, but the snow board was deployed and ready. I think the 11.8" value for new snow depth is a bit low. The wind blew during the heaviest snowfall, and I think the place where I keep the new snow board was a bit scoured. The total snow and ice SWE is OK, I believe, because there was denser stuff below the new snow.

In my driveway four miles away, there was an average new snow depth of 17 inches. The wind was strong throughout the snow event, so I guess that's the way it goes. And, I discovered a leak in one of my big cylinders. As the new snow board core sample sat and melted, it lost some water. 1.54" was left in the cylinder when I measured it, but I entered NA in the blank.

It was not windy at all as the snow fell over night and through the morning, so the SWE of 0.35" is a very good estimate of the SWE of the new snow. The precipitation did turn to rain shortly after this day's measurement was made.

Much of the weight of the SWE samples is coming from a compact grainy ice layer at the very bottom of the pack that is in contact with the soil. When my core sample grabs the soil below, the soil is not frozen, and the dense grainy ice is entwined with the grass.
