11/20/2011 7:25 AM T T M M M I gave the total snow depth yesterday, as well as its water equivalent. No new snow of significance took place yesterday. In previous years, I took snow depth and its water equivalent on a weekly basis and have done so on Monday. Will do this tomorrow morning.

1/19/2012 7:25 AM 0.20 7.5 0.33 10.0 0.55 There had been some blowing and drifting of snow at the site. Some of the snow probably did not get in the gage, but did collect on the measuring table. The water equivalent of the new snow of 0.33 inches is probably more representative.
1/20/2012 7:45 AM 0.03 0.5 M 8.0 0.59 Some settling of the snow by 2 inches occurred between yesterday's reading and today's. Please note: I will be away from the area for a few days.

1/27/2012 7:45 AM T T M 3.0 M Precipitation that occurred during this past 24 hour period was a mix of rain, sleet, and snow. It only amounted to a trace. Since I took a core sample yesterday, and the snow depth has not changed, I did not take one for this observation.
1/28/2012 7:45 AM 0.00 0.0 M 2.5 M Unless significant new snow occurs over the weekend, I'll take the next core sample during my Monday morning report, provided the snow depth is 2 inches or more.

If temperatures get to where they are forecast to be today, there will probably be just a trace of snow on the ground tomorrow where I measure it. Since the average snow depth was 1 inch, I took no core sample of it.
1/31/2012 7:30 AM 0.00 0.0 M T M The measuring area for snow is almost bare ground. What is left of the snow is not far from where I shoveled the driveway.
2/1/2012 7:50 AM T 0.0 M T M Toward 9 PM, we had a few drops of rain that fell at the site. I happened to be outside when this event happened. The gage did not register this when I checked it this morning.

2/23/2012 7:30 AM 0.03 0.2 M M M The precipitation that fell during the past 24 hours started out as rain, then changed over to snow during the night. The new snow that fell of 0.2 inches actually is also the total snow at the site. I left the number for that as NA, since 0.2 is not half way between zero and a half inch, and to put in a zero for depth of total snow and ice would be misleading.
2/24/2012 7:25 AM T T M M M A shower of snow grains fell at the site early in the afternoon. All had melted away during the remainder of the daylight hours. Thus, the trace of new snow occurred after the shower had passed, not at observation time this morning.

2/26/2012 7:54 AM 0.01 0.2 M M M Again, the actual amount of new snow and total snow depth is the same, 0.2 inches. However, the total snow amount is less than half of a half inch. Thus, reporting NA seems more appropriate here.
2/27/2012 7:25 AM 0.01 M M T M Light snow was in progress when I took my observation yesterday. The snow had stopped while I was away from the site and considerable melting had occurred by the time I returned to it. Thus, I do not have a figure for how much new snow fell for this observation. A trace remained on the ground for this morning's observation. This amount takes into account what snow I reported yesterday and what remains of snow that fell between yesterday's observation and this one.
2/28/2012 7:20 AM 0.00 0.0 M T M
2/29/2012 7:25 AM 0.04 0.4 M 0.5 M Again the new snow depth and the total snow depth are the same - 0.4 inches. However, rounding the total depth to the nearest half inch gives 0.5 inches. Please note - I will be away from the site from later today for a few days. The earliest observation I'll be able to make from this site will be Wednesday morning, March 7.

3/19/2012 7:35 AM 0.61 1.5 0.43 1.5 0.43 Moderate snow in progress at time of observation. Believe that the water equivalent of 0.43 inches is the more accurate one as measured from the measuring table. Snow had accumulated on top of the gage cylinder and it fell in when I lifted the cylinder up to get its water equivalent.
3/20/2012 7:12 AM 0.09 M M 1.5 M The new snow that fell melted during the day. I have no measurement of it. Much of the snow that fell that was measured for yesterday's observation melted as well. Thus, the total amount of snow and ice given here is what I just measured today. Seeing that it was below two inches, I did not calculate a water equivalent of it. There were a few bare spots at the site as well.

5/11/2012 5/16/2012 7:45 AM 6 0.00 M M Please note, there may have been measurable precipitation that occurred here while we were away from the site. I removed the inner cylinder before leaving for fear of temperatures going to freezing or below, but kept the funnel on the gage to keep evaporation at a minimum. There was no water in the gage when I checked it this morning. Thus, if any precipitation occurred during our absence, it all evaporated by the time we returned.
