Best est. avg. is 1", and average of two core samples = 0.25" water content. My daily core measurements of this north-facing area show that the snow depth keeps compacting slowly as the surface melts, but little overall loss of water content. The density (inches H2O per inch of snow depth) has gradually increased over the past two weeks since most of the snow accumulated, from about 0.08 to 0.25.

Avg. of two snow cores at 1" snow depth = 0.24" water, so, reporting overall average snow cover for the area, as 1/2 x 1" = 0.5" depth, 1/2 x 0.24" = 0.12" water content.
12/20/2013 7:00 AM T T T T T A very light dusting of snow fell during the night. The snow in the gauge, melted, amounts to about 0.005 inch of water; I guess I'll just call it "Trace". Old snow on the ground still measures about 1 inch in places, but only on perhaps 1/3 or 1/4 of my backyard measuring area, so I'll just call it "Trace" overall. Most areas in this neighborhood, not slightly north-sloped like mine, have no snow left or just a trace in small patches.

12/30/2013 7:00 AM 0.00 0.0 M 1.5 0.14 Today I made and averaged 3 snow core measurements around my measuring site of total (old) snow: one on a snow board, 0.14" water content; one on a low glass outdoor tabletop that I often use for snow depth measurements, 0.15"; and one on an undisturbed grassy area, 0.13"; all with approx. 1.5" snow depth; so, average water content, 0.14".
12/31/2013 7:00 AM 0.00 0.0 M 1.0 0.13 Average of two core measurements on old snow, 0.15 and 0.11" water content, avg. = 0.13. Total snow on ground ranges from 0 or trace, to 1 to 2 inches.
1/1/2014 7:00 AM T T T 0.5 0.10 A trace of graupel had fallen by 7 a.m. Hard to estimate average amount of old snow; about 2/3 of area around measuring site still has snow cover, ranging from 0.5 to as much as 2.5 inches in shaded areas. I'll call the typical value as just 0.5 inches; and a snow core at 2.5" old snow depth = 0.51" H2O, so I'll record the water content at 0.5" depth as 0.51/5 = 0.10 inches water content.
1/2/2014 7:00 AM 0.09 0.5 0.09 1.0 0.15 Snow fell mostly as graupel during several periods of snow; mostly 7 to 9 am and from 4 to 7 pm.

1/13/2014 7:00 AM 0.00 0.0 M 0.5 0.13 Total old snow depth ranges from 0 to 4 inches; about 2/3 of ground is bare, 1/3 is snow covered; estimate of average depth on covered part of the area is 1.5 inches, hence est. overal average snow cover is 0.5 inch. One snow core where depth is 2.5" = 0.66" water content, hence reporting overall area average of 0.66/5 = 0.13" water content.
1/14/2014 7:00 AM T T T 0.5 0.13 Old snow covers approx. 1/4 of the area around measuring site, ranging from 1 to 3 inches; rest is bare. Snow core at 2.5" snow depth = 0.63" water. Est. overall average snow depth = 0.5", = 0.13" water.

1/24/2014 7:00 AM T 0.1 T 3.0 0.16 Snow from the previous night's snowfall ended by 9 a.m. yesterday; depositing about 0.1 inch of additional snow between 7-9 a.m., amounting to only a trace (a little less than 0.005") in the gauge.
1/25/2014 7:00 AM 0.00 0.0 M 1.0 0.14 Hard to estimate overall average remaining snow depth and SWE from core; cover varies from bare ground, to 1" (mostly new snow), to as much as 4" total (recent snow + older previous snowfalls still remaining in shaded areas).
1/26/2014 7:00 AM 0.00 0.0 M T M It remains very difficult to report an accurate amount of total old snow & ice, because some of the area (partially shaded) still contains between 1 to 3 inches of old snow; a snow core at 2.5" depth showed 0.64" of water. Area with snow represents perhaps 10% of the total area at measuring site; so, one might calculate perhaps an average overall snow depth for the whole area of 0.2 inches, with averaged overall water content of 0.05 inch. However, given the estimated errors, I'll just report the total snow as "Trace".

Bottom layer elsewhere is a crust of frozen slush, and noticeably orange (really--from dust in the snow it seems, NOT just for the Broncos this time). Total on-the-ground snow measurement is variable because previous old snow cover was variable, 0 to 3 inches, and bottom half inch is crusty ice. [P.S. added next day, in spite of my best effort to have taken a "representative" snow core this day, my measurement the next 2/1, with more snow fallen, showed 0.95" total melted value, less than the 1.25" I measured today--showing the irregularity of total snow and SWE on the ground.]

5/8/2014 7:00 AM 0.51 M M M M Hurray, I finally got to deploy and use my hail pad! There were two hail storms; a very brief one (2 minutes?) at about 2:30 pm, pea-sized hail; rain gauge after this storm read 0.02 inch water, then a slightly longer one (about 5 minutes) at 7:25 pm, with 1/4 to 1/2 inch size hail, but not heavy enough to do damage. I will file a separate hail report for each of these, including data from the hail pad deployed during the second hail event. Followed later by steady rain during the night.

5/11/2014 7:00 AM 0.82 M M M M Precipitation so far, measured at 7 a.m., has been almost entirely rain, but just beginning to turn to sleet at this time; not noticeable anywhere on the ground except in the funnel of the rain gauge, where a small amount of frozen material has collected in the mouth of the funnel in addition to all the water in the tube.
5/12/2014 7:00 AM 0.95 5.5 0.56 5.5 0.56 Much of the first precip. fell as sleet and snow melting as it fell. No snow has accumulated on paved surfaces; the accumulation reported was what remains on the lawn.
5/13/2014 7:00 AM 0.03 0.5 M T M A little snow continued to fall on the morning of the 12th, mostly between 7 to 9 a.m. The (temporary) accumulation of 0.5 inch is my estimate; most or all of it melted away during the day. On the morning of 5/13, remaining snow on the ground ranges from none (most of the area) to about an inch; reporting the average as "trace".

During this we were in Lakewood about 1 mile southeast of our home observation station, and here, there was significant hail, up to about 1/2", with many leaves knocked off trees. Back at the observation site, can't tell for sure if there was any hail; perhaps a little, a few leaves knocked off. Rain gauge showed 0.35 inch when observed at about 9:15 pm, when rain had ended; more rain fell during the night, giving the morning reading of 0.62" total.
