10/5/2010 6:00 AM 0.00 0.0 M M M The dew was so heavy that I wonder if we reached 0.01 inch condensation. I will think about a "dew slide" that collects dew over a large area and a way to ultimately measure it. However, I suspect the collection will depend on the alignment of such a slide with the night winds and the measurement could be unsatisfactorily noisy.

11/25/2010 6:00 AM 0.15 M M M M With temperatures dipping below freezing at night, I use an open rain gauge for collection. The increased wall area collects droplets, which may actually be from mist or fog. The total of these droplets was measured as 0.01" of the 0.15 "precipitation. I wish I knew how best to report this succinctly.

When the grass is poking through the snow, the ground probably warms more than my white snowboard. Hence the snow remaining may be an overstatement. I might try a clear snowboard next year, in parallel with my current boards.

Start Date End Date & Time Duration in Days Precipitation Snow Depth Snow Depth SWE Notes
11/21/2010 11/23/2010 6:00 AM 3 1.07 0.0 M Winter has arrived! I had to thaw the ice that formed in the rain gauge before I could measure it. Quite a temperature change from yesterday's high of 60 degrees.
1/8/2011 1/13/2011 7:00 AM 6 2.00 2.0 0.22 I left with clean snowboards and returned to 2 inches of snow.
1/29/2011 1/31/2011 6:00 AM 3 T 3.0 M The pattern of the precipitation on the bottom of the rain gauge suggests that it fell as snow, melted and refroze. The snow board was clean so evaporation must have been strong during the melting period.
6/11/2011 6/17/2011 1:00 PM 7 0.79 M M No rain yet today.
