12/19/2011 7:00 AM 0.00 0.0 M 3.5 0.60 It has been a challenge to try to post a "correct and accurate" average total snow depth on the ground this month. My chosen registered location--my back yard around my rain gauge--has a relatively sheltered, partly shaded, slightly northward sloping exposure, hence at this time of year it gets little sun and snow is scarcely melting, even on our "relatively warm" days. My reported snow depth and melted H2O content from core is as accurate as I can make, and each day I'm surprised how little the snow cover has been depleted, though I know other nearby locations with different exposure have only "trace" snow remaining. Around my own observation site, total snow remaining on undisturbed ground now ranges from 4-5" to 2-3", to some areas with trace or no snow at all.

Thus, H2O content measurements on successive days: 1.37, 1.09, 1.16, 1.35 inches; not much to conclude except that the +/- variability in my measurements is more than 10%.

The value, as I similarly commented on in a note I posted a few days ago, was surprisingly high--again, showing the variability (in spite of my effort to make the core measurement at a uniform, representative location) of the snow depth and water content of the old snow on the ground.
