12/10/2009 6:00 AM 0.08 0.7 0.08 3.0 M We have blizzard conditions; continuous blowing and drifting snow. The snow is level across both snowboards at 2.8 inches. However, the settled snow in the gauge is only .7 inch new snow. Temperature is about 3 degrees F.

12/12/2009 6:00 AM 0.00 0.0 M 3.0 M Snow remaining varies from 2.5 to 4.5 inches around my lot. Since the snow drifted to be nearly level, the variation results from the roughness of the lot. The snowboard thickness of .625 inches should probably be added to measured depth since drifting conditions existed during/after the snow fall.

I report the total of 1.4 inches as "new snow." The compaction of old snow hid the fact of any snowfall, but the 0.2 inch crust was very apparent.

1/24/2010 6:00 AM 0.30 0.0 0.00 2.0 M Overnight temperatures above freezing and rain have caused uneven melting. Ditches and slopes are almost bare, while the flat lands still have up to 3.0 inches of cover.

3/1/2010 6:00 AM T T T 5.0 M The trace of precipitation started as a few flakes and switched to rain. The snow should be recorded as a T- and the rain a T+. The temperature warmed up enough to form a stiff crust on the snow -- strong enough to hold my puppy, but not me.

3/3/2010 6:00 AM 0.00 0.0 0.00 4.0 M Melting continues, but is most apparent on south facing slopes or over the warmer septic fields. Level ground away from septic fields is holding a snow level near 5.0 inches, simply generating a harder crust in the temperatures near freezing.
3/4/2010 6:00 AM 0.00 0.0 0.00 3.5 M Melting continues, but the hard crust doesn't change much. Most melting is in the shallow areas and where the bare spots continue to grow.

3/6/2010 6:00 AM 0.00 0.0 0.00 2.5 M Melting continues and the remaining snow is quite uneven - the surface of the snow is now rippled in spots making measurements a judgment call. Level land remaining snow thickness is about 3.0 inches; slopes facing the sun have less than 1 inch remaining snow while shaded slopes still approach a 4 inch depth. Evidence of the warmer septic fields is beginning to appear and the Canada Geese are invading the subdivisions which are on well and septic.

3/9/2010 6:00 AM 0.00 0.0 0.00 0.5 M Melting is continuing. About half the yard is clear of snow and the remaining snow is porous, with large agglomerations of icy snow. The depressions from goose tracks have melted more than the undisturbed snow. Today's .5 inch remaining is on the low side of .5 inch while yesterday's was on the high side.
3/10/2010 6:00 AM 0.09 0.0 0.00 T M The snow finally melted to an average depth of less than 0.25 inches. And the night time temperature is now high enough that I put my funnel and central tube back in the rain gauge.
