10/24/2019 7:00 AM 0.38 5.2 0.38 M M About 2:00 p.m. I began getting a few light sprinkles. 2:40 there was a short period of light rain but not enough to completely wet down the deck. Approximately 8:00 p.m. I began getting light flakes of snow. By 8:30 p.m. the snow was light but steady. The ground and collection area was to warm for the snow to stick. 5:15 a.m. there were still a few flakes of snow falling. By 6:00 all snow had stopped. Temperature was 30 degrees. 7:00 a.m. the temperature had dropped to 27 and no additional snow fall.
10/25/2019 7:00 AM 0.00 0.0 M M M 23 degrees at 7:00 a.m. this morning with mostly clear skies.

10/27/2019 8:00 AM 0.03 1.0 0.03 M M Collection platform and tube were all coated with a layer of ice. A light fall of large snow flakes are falling lazily straight down. 1 inch of snow on collection platform over a layer of ice. Collection tube funnel and bottom of liquid measuring tube coated with ice. Melted core value included melted ice and snow collected on the funnel and tube.
10/28/2019 7:00 AM 0.36 6.3 0.36 M M Through out yesterday morning on and off light flakes of snow changed to grapple and then light flakes of snow, etc. Yesterday afternoon it changed to mostly all grapple falling with varying intensity. The snow pellets were small but a steady fall. During the evening I was not able to make observations... was away from home. This morning it was 17 degrees with a light frozen "mist" falling. (edit: SWE changed from 3.60" to 0.36". PG)
10/29/2019 7:00 AM 0.15 1.5 0.15 6.1 M very small flakes/ice crystals, wind swirling, and 16 degrees Not able to get an accurate core sample as I had taken my collection tube inside from previous snow. Tried marking a ring with the tube, removed snow around tube and then slid the upside down tube with snow inside onto a flat piece of heavy paper and poured snow back into collection tube to take inside to melt. Once melted poured water into small liquid measuring tube. Thus, I am not sure of the accuracy of my liquid measurement.
10/30/2019 7:00 AM 0.28 3.8 0.28 8.5 M Snow fall has stopped and 5 degrees. Yesterday's snowfall was consistent small flakes mixed with grapple. Yard is surrounded by 30-40+ foot tall wall of spruce trees thus mostly a straight down drop of snow with no drifting. Water content measurement was snow collected in 4 inch collection tube and not a core sample as snow was like powder and snow in tube was mostly level.
10/31/2019 7:00 AM T T M M M Approximately 8:20 - 8:45 a.m, I had a period of snow flurries. Once the sun came out they quickly melted.

11/26/2019 12:30 PM 1.49 19.6 1.49 M M This report was taken over the duration of 7:00 a.m. 11/25/2019 to 11/26/2019 at 12:00 p.m. due to being away from home at the 7:00 a.m. time period. This time period included the start to finish of the snow storm. There was light swirling wind. Thus, I took 3 separate snow depth measurements over a level 4-6ft. area. Each measurement was approximately 2 away from each measurement. I averaged the 3 measurements for a total snowfall. 19.3, 22.4, 19.2 inches for an average snowfall of 19.6 inches at 12:30 p.m. There are still very light periods of snow. Flakes are very small with no real accumulation. Due to the depth of snow which extended well over my 4 inch collection tube, I used my metal measuring ruler to level the snow across the top of the tube and melted the full tube of snow (or .0758 inches of water per 1 inch of snow). 12 inches of snow equaled .91 inches of water. I then subtracted 12 (depth of snow in 4" collection tube) from the 19.6 (total depth of snow) which left 7.6 inches of snow that water content was not accounted for. I multiplied the 7.6 inches of snow (not accounted for) by the .0758 inches of water per inch of snow and added that amount to the .91 inches of water for the 12 inches of snow that I knew the water content for.

Late afternoon and into the evening the snow flakes became smaller. Morning accumulation was all very icy. Water content measurement is the melt value of snow and rain collected in my 4" diameter collection tube. The bottom of my tube had approximately 1 inch of ice. Snow on my collection table had a hard ice on the bottom thus unable to get a good core for melt value. There were few periods of light wind but for the most part the snow fall was vertical.

Yesterday after my observation, I cleared 1/2 of my wooden collection platform. During the day there was a continual on and off light to moderate snow during the day with little or no breeze during the day. The snow melted as it fell on my collection plate as well as the areas shoved for my dog to get off the deck and out into the yard. Snow did not start collecting on the collection plate until approximately 5:00 p.m. however I had by that time about 3 inches in my 4" collection tube and it was pretty much a uniform height in the tube. Thus I thought and used the 4" collection tube's accumulation as being a more accurate barometer of actual snowfall depth. (Reminder, my April 12th reading was taken at 8:00 a.m.) At 7:00 a.m. I had a little over 1 inch accumulation of snow above the top of the full 4" collection tube. p.s. My backyard where my collection area is located is surrounded by 13 (30'-40'+) mostly blue spruce trees and, a my two story house sheltering the collection area. In addition, I also have spruce trees in front of our home all situated on almost a 1/4 acre lot.

9/9/2020 7:00 AM 0.93 3.9 M M M Power outage this morning... 7:00 a.m. 9/8 temp was 34 degrees. 7:30-8:00 small ice/slush pellets began to fall intermittently changing over to light snow in the afternoon. By 5:00 the snow had changed over to a wet heavy snow. Because of the wet snowfall, I used only the snow collected in my 4 inch collection tube after removing the rain gauge and funnel top for my melted snow amount. Our 2 story house is surrounded by 18 - 30 to 50 foot tall Blue Spruce and Ponderosa Pines so I have a good wind brake for our 1/4 acre lot.
