11/5/2018 5:56 AM T M M M M I was surprised to see water in the gauge since I did not recall rain yesterday or overnight. It is possible the water in gauge may be from rain on previous day that was not completely cleaned out of the gauge.

11/14/2018 6:30 AM 0.15 0.0 0.00 0.0 0.00 Gauge on post had solid ice in bottom of it. Added hot water then measured (subtracting added water) to give 3.9 mm (The web site seems to convert my 3.9 mm to 3.8 mm in the database). No ice or snow on snow board or on the ground.

11/17/2018 8:00 AM 0.23 2.1 0.24 M M This information was sent in a Significant Weather Report last night. No new precipitation since last night. The total gauge precipitation from observations for Nov 16 was (5.9+5.8)=11.7 mm melted value. The total snow board precipitation was (5.5+5.3)=10.8 cm giving (5.8+6.0)=11.8 mm melted value. While taking snow core on board yesterday evening there was a crunching sound while pressing down through snow as if a thin ice layer had formed in the layer of snow. Some of the snow on the board did feel icy.
11/18/2018 8:00 AM T 0.0 0.00 M M This 0.1 mm observation was obtained by using the digital scale technique to weigh the precipitation gauge.

11/20/2018 6:45 AM 0.07 0.3 0.02 M M Layer of ice 2-3 mm thick in bottom of cylinder. Also layer of ice below the snow layer on the board. I was not able this time to get a good measurement of thickness of ice on the board or to collect ice as part of the snow board core.
11/21/2018 7:30 AM 0.19 2.7 0.20 M M Of the 4.9 mm observed in the gauge 4.8 mm was observed yesterday at 10:04 pm and 0.1 mm was observed between then and 7:30 am this morning. of the 6.8 cm observed on the board, 6 cm were observed yesterday at 10:04 pm and 0.8 were observed at 7:30 am. The 0.8 cm that fell overnight had a snow water equivalent near 30 mm/mm. It is snowing again this morning at observation time.
11/22/2018 6:45 AM 0.07 1.5 0.08 M M The 1.9 mm from the gauge was measured after the snow stopped yesterday at about 3:45 pm. Between 3:45 pm yesterday and this morning there was only a Trace in the gauge. The 3.9 cm of snow on the board giving 2.0 mm of water equivalent was also observed yesterday at 3:45 pm. There was nothing measurable off the board this morning. The surface of the snow board was icy.
