Elevated surfaces that had cooled first, yielded snowfalls up to 1.9 inches, while my snowboard only showed 1.4 inches. The horizontally blown snow that covered the outside of the gauge had to melt before I could get an accurate measure of precipitation inside the gauge. In such windy conditions, poor snow capture might give a low estimate of total precipitation. However, the snow water content was taken from a sample off the snowboard. Changeover to snow began about 4:15 PM.

The overnight snow was extremely fluffy and round off errors make it look fluffier than it was. I estimate about a real 28:1 ratio of snow depth to water depth.

1/2/2013 6:00 AM 0.00 0.0 M 0.5 M Actual "Total Snow on Ground" is approaching 0.25 inch, but still on the high side. The highly reflective/insulating snow board has inhibited warming of the accumulated snow so the depth there is 0.8 inch, but actual snow on the grass is only one third of this. It is time to suggest an alternate snow board that behaves more like my local vegetation.
1/3/2013 6:00 AM 0.00 0.0 M T M A careful check of the average remaining snow around the property fell below 0.25 inches so it now rounds down to a trace.

1/7/2013 6:00 AM 0.00 0.0 M T M Extremely heavy frost last night, but no precipitation. By the weighing method, the frost on the outside of the gauge was equivalent to 0.04 inches of precipitation! Surprising since the dew point is now 4 degrees colder than the air temperature of 20. Everything just glistens and car windshields will need extra time to warm up.

So, I have tried to level the snow board today to minimize the effect of drifting into the slight depression that can form as the heavier snow board sinks.
