10/14/2018 7:00 AM 0.21 4.0 M 4.0 M This snow came in with a strong wind, so the gauge probably didn't catch all the moisture. New snow is what I measured at 7:00, I don't know how much melted. I think it is also low. It is muddy and soft underfoot.

11/17/2018 7:00 AM 0.22 5.0 M 5.0 M This came in with strong wind on occasion, and some drifting. The ground is warm, so the snow is melting on the bottom with the top very light and fluffy. The gauge missed some of the moisture, maybe about a third of what came down.

2/6/2019 7:00 AM 0.04 0.2 M T M Most of the snow came straight down, but the wind picked up before 7:00. There was very little snow overnight, so I think that the gauge probably caught most of this moisture.

3/1/2019 7:00 AM T T M T M It rained briefly just after noon on Feb 28, and there were a few snowflakes just before 7:00 AM. The trace of old snow doesn't have much water content. Most the snow that came down in February has either melted or evaporated.
3/2/2019 7:00 AM 0.02 0.8 M 1.0 M This came in with a strong wind, so the gauge probably missed a hundredth of moisture.

3/7/2019 7:00 AM 0.13 1.0 M 1.0 M This came in with light wind, 10 mph and less, so the gauge probably caught most of the moisture.
3/8/2019 7:00 AM 0.00 0.0 M T M It is impressive how much snow can melt in one day. Most of the ground in clear of snow with only small drifts in the most protected places.
3/9/2019 7:00 AM 0.17 2.8 M 3.0 M We had snow that melted, then some rain, then snow with a wind. The gauge probably didn't catch all the snow, but a fair portion of what came down melted or came down as rain. I don't think a core sample would yield much more than what was in the gauge.
3/10/2019 7:00 AM 0.02 1.0 M 0.5 M The ground is still mostly snow covered, but there was a lot of evaporation/melting when the sun came out yesterday. The top inch of soil is saturated, but the ground is frozen below that inch. The result is lots of small puddles of water where the water cannot get through the frozen ground.

3/14/2019 7:00 AM 0.36 12.0 M 15.0 1.93 The wind was 20-30 mph for a large portion of this storm, so the gauge probably caught less than half the moisture. The new snow is a guess. I shoveled a clear spot that wasn't drifting much, and used that as a gauge for new snow. I have a spot that over the years has proved to the closest to the average snow for the whole area. That is where I took the total snow measurement and the core sample. The wind in this storm was more out of due north than usual, so the spot might not be as good as normal. Also, yesterday, we had a lot of rain before the snow started, so the core sample is probably missing up to a quarter of an inch that was in rain.
3/15/2019 7:00 AM 0.00 0.0 M 8.0 1.36 The core sample is from 200 yards south of the rain gauge in our front pasture. This point was between sage brush drifts and at a point that was about the average depth of snow that wasn't enhanced by a drift. I think it is representative of the water content of the rangeland near the house. I don't know how much of this storm came down as rain, certainly a large amount (up to a quarter inch maybe), and there has been melting into the ground and wind movement on the top of the snow. There is also about a one inch crust on top of the snow.

It is probably representative of the moisture content of the rangelands surrounding the house. The amount of moisture in the core sample is the total of 0.98 and 0.32. I originally reported 1.32, but the real total is 1.30.
3/19/2019 7:00 AM T T M 5.0 M We had a discussion as to whether or not there was any snow last night. I think there were definitely some small snowballs on top of the ice and ground there were not caused by the heavy frost.

3/22/2019 7:00 AM 0.00 0.0 M 1.0 M Total snow is a guess. The snow really shrank yesterday, but over half the ground is still covered by a little snow. Most of the snow has either evaporated or gone into the frozen ground. So far, we have had very little runoff from the rangeland.

The core sample was taken about 200 yards south of the rain gauge location in an open area away from drifts. It is conservative because it rained and the bottom of the snow is melting. This evening I discovered I had entered an incorrect amount for the snow we had, it was 5 inches rather than 4 inches.

5/19/2019 7:00 AM 0.29 0.3 M T M I measured 0.27 before it started snowing, so the snow only provided 0.02 of moisture at the most. There is a little snow on the grassy areas, but most of it melted by this morning. The snow measurement is from a board and on the cars.
5/20/2019 7:00 AM 0.45 T M 0.0 M This is an exact measurement. There isn't any snow on the ground right now, but just above us (a couple of hundred feed) there is snow visible on the ground.
5/21/2019 7:00 AM 0.17 3.0 M 3.0 M With the 10-15 mph wind, the rain gauge probably missed at least a tenth of an inch. The snow measurement is not very accurate. The snow is held up by the grass blades, and it has melted near the ground. On some boards, it was 2 inches, which is probably a better gauge of what actually fell. But it is all an estimate even though I am quoting actual measurements.
5/22/2019 7:00 AM 0.49 6.0 M 6.0 M Some of the snow came in with a 10 + mph wind, but most of it came down with only a little wind. I would guess the gauge missed about 0.05 of an inch. About a third of the moisture came down as rain. The snow measurements were from 4 to 10 inches, but my guess is 6 inches. My wife thinks I am measuring too much of the grass height. Anyway, take the 6 inches with a grain of salt.
5/23/2019 7:00 AM 0.29 M M 1.0 M It snowed most of yesterday morning, but it was also melting the snow on the ground. I have no idea how much new snow we got, thus I have listed the new snow as unknown. The total snow is my guess as to how much the average over the area is.

7/1/2019 7:00 PM This hail was seen on Coal Mountain from 5 miles away. My brother said that about 1/4 section (160 acres) was white from his house, and was probably in Section 24, Township 32N, Range 81W. No one was in the area of the hail, but it was thick enough to be easily seen from 5 miles away. NA NA NA 10min False
