10/10/2019 7:00 AM 0.13 4.5 M 4.5 0.18 I forgot to take the funnel and inner tube out, so this amount is a little low. Also, there was some wind with the snow. We didn't get any measurable moisture until the temperature was in the 20's, so my guess is that the melted core is only a couple of hundredths from the total amount.
10/11/2019 7:00 AM 0.03 M M 3.0 M It snowed and melted all day. I was unable to measure the new snow.

10/20/2019 7:00 AM 0.07 1.5 M 1.5 M We started with light rain before becoming all snow. This snow came in with a little wind, so I expect the gauge didn't catch all the moisture, but I think it caught most of it.
10/21/2019 7:00 AM 0.24 M M 2.5 M This storm came in with a wind, so the gauge probably did not catch all of the moisture. It snowed hard and melted most of the day, and I was unable to determine the amount of new snow. My guess is close to half a foot.
10/22/2019 7:00 AM T T M T M The snow melted straight into the ground with no runoff. I put some stuff into our compost last night at about 9:00 and it was snowing very lightly.

10/27/2019 7:00 AM 0.26 5.5 M 5.5 M This came in with a wind, 5 to 15 mph, so the gauge didn't catch all the moisture. The bottom of the snow on the driveway has about half an inch of slush from the melting snow.
10/28/2019 7:00 AM 0.04 3.0 M 5.0 M The wind blew most of the time, so the gauge probably did not catch all the moisture.
10/29/2019 7:00 AM 0.05 2.0 M 5.0 M This is an exact measurement. The new snow is a guess. It is very light and fluffy, and came in with a 5-15 MPH wind. My guess is the gauge did not catch all the moisture.
10/30/2019 6:30 AM 0.01 T M 3.5 M The trace of snow is a guess. It did snow, probably less than half an inch.
10/31/2019 7:00 AM 0.00 0.0 M 2.5 M Total snow is a guess. The wind rearranged the snow to almost bare ground and small drifts.
11/1/2019 7:00 AM 0.04 1.0 M 2.0 M This snow came in with almost no wind, so the gauge caught most of the moisture. Most of the open areas had 1 inch to 3 inches; my guess is total snow is about 2 inches. There is more in drifts.
11/2/2019 7:00 AM 0.00 0.0 M 1.0 M Total snow is a guess. There are some bare patches, and small drifts. My guess is the average is about 1 inch.

11/27/2019 7:00 AM 0.04 2.0 M 5.0 M The new snow is a guess. We kept shoveling the driveway, and took off about 2 inches of new snow. At least half this snow came straight down, so the gauge probably caught most of the moisture.

12/9/2019 7:00 AM 0.12 2.0 M 2.0 M This storm came in with a light wind, 3-7 mph, so the gauge probably caught most of the moisture. The total snow is 2 inches in most areas, with some drifts left over from the November snows.
12/10/2019 7:00 AM 0.00 0.0 M 1.5 M There is snow covering everything, and drifts behind every bush.

1/28/2020 7:00 AM 0.16 1.0 M 1.0 M A very unusual weather pattern for here. We had a lot of rain for January until noon, then rain mixed with snow, then snow that came straight down.
1/29/2020 7:00 AM 0.06 1.0 M 1.0 M This snow came pretty much straight down with very little wind. The gauge probably caught most of the moisture.
1/30/2020 7:00 AM 0.15 2.0 M 2.0 M This is an exact measurement. This snow came in with very little wind, so the gauge probably caught most of the moisture. The new snow is a guess; it snowed and melted all day.
1/31/2020 7:00 AM 0.04 0.5 M 1.5 M This snow came in with the usual wind, so while the gauge probably ought most of the moisture, it didn't catch all of it. New snow is a guess; the wind has rearranged the snow, so Total Snow is what I measured, but there are also drifts.

2/3/2020 7:00 AM 0.24 9.0 M 9.0 M The drifts are up to 24 inches deep between the house and the rain gauge. The snow came in with a 15-30 mph wind, so the gauge probably only caught about half the moisture.
2/4/2020 7:00 AM 0.20 8.0 M 14.0 M This came in with a 15-30 mph wind. The gauge probably caught less than half the moisture. The new snow and total snow are guesses. Everything is either blown clear or a drift, ranging from a couple of inches to 30+ inches deep.
2/5/2020 7:00 AM 0.00 0.0 M M M The wind has rearranged the drifts. Areas that had 14 plus inches yesterday are mostly bare today, and all the drifts are in new areas. I don't know how to estimate the average depth of the snow. The drifts are really solid and dense, so there is a lot of water content.
2/6/2020 7:00 AM T T M M M The total snow depth is dependent on how high the material that is blocking the wind is. The result is that the snow goes from an inch to 30 plus inches based on wind protection. I cannot guess what the average is.
2/7/2020 7:00 AM 0.13 2.5 M M M This snow came in with no wind, so the gauge probably caught all the moisture. The total snow depth is from 3 inches to 30 plus, and I cannot guess what the average is. I'm sure it is over 6 inches but beyond that I cannot make even an educated guess.
2/8/2020 7:00 AM 0.00 0.0 M M M There is a snow cover on the ground, but it ranges from a couple of inches to 30 plus inches, and I am unable to estimate an average.
2/9/2020 6:15 AM 0.05 1.0 M M M The measurement is as accurate as possible. With the light wind, less than 10 mph, I expect the gauge probably caught most of the moisture. There is a complete cover of snow, but it varies so much that I cannot guess what the actual average is.

2/13/2020 7:00 AM 0.19 4.5 M M M Most of this storm came in with only a little wind, but there was about an hour of 10-15 mph wind. I expect the gauge caught all but a couple of hundredths of an inch. The total snow is impossible for me to guess, the size of the drift depends on how tall the bush is. There is a lot of snow on the rangeland, I just cannot guess how much.

3/12/2020 7:15 AM 0.05 0.9 M 1.0 M This is an exact measurement. There is enough wind with this snow that the total in the rain gauge is probably a hundredth of an inch less than it should be.
3/13/2020 7:00 AM 0.06 2.0 M T M This snow came in with enough wind that the gauge probably missed a couple of hundredths of moisture.

3/26/2020 7:00 AM 0.07 1.7 M 1.5 M This came in with a little SW wind, so the gauge might have missed one hundredth of an inch of moisture.

My guess is I missed .05 of an inch or so. A lot of the snow melted very quickly, so the 4.5 inches that I measured is probably much less than what came down.
4/13/2020 7:00 AM 0.01 0.5 M 2.5 M It snow all day, and snowed hard for an hour, but when it was snowing hard it was all blowing hard, so the gauge did not catch most of the moisture.

9/8/2020 7:30 AM 0.84 9.0 M 9.0 1.35 This storm came in with a 10-20 mph plus wind, so the gauge didn't catch all the moisture. Most of the moisture came down as snow, but the snow was melting on the bottom when I took the core sample. The snow varied in depth from 6 inches where it was blown clear to much more in any protected spot. I think the 9 inches is close to the average. I melted the snow in the core sample by adding water, so the amount is the accurate net number from 10 different amounts.
9/9/2020 7:00 AM 0.09 2.0 M 4.5 M This came in with a 10 mph plus wind, so the gauge probably did not catch all the moisture. New snow is a guess based on what accumulated on the cleared areas. There has been a lot of melting so I did not think a core sample would provide much information.

9/13/2020 7:00 AM 0.00 0.0 M M M The snow near the gauge has finally melted. There is some snow where it is very protected or the drifts were especially deep, but those areas are 1/3 of a mile away.
