The possibility of snow had been forecast, but the ground was too warm for any accumulation; if any flakes did fall, it must have been while we were not watching. By observation time, almost all of the accumulated rain had frozen in the gauge.

Yesterday's rainfall had ended well before the start of the current observation period, which began with the temperature at 35(F). Between 7AM and 8AM, the temperature dropped at least 5 degrees. Onset and end of snowfall were difficult to determine, because it began and ended with very sparse, very small flakes. Even during the heaviest fall (roughly 9AM to 11AM), the flakes were not very large, and visibility was only slightly restricted. Overnight, much of the snow disappeared from pavements and less-sheltered areas of lawn.

Snow depth varies considerably because the wind blew some around after most had fallen: about 0.1 inch has blown in under a roofed but unscreened porch, and some open areas have as little as 2 inches accumulation.

Gradually it became clumpier - not large flakes, but clumps of small flakes, which broke apart on impact. When snowfall ended, the fallen snow did not fully cover any level surface - the underlying color could readily be seen between the individual or clumped flakes.

1/16/2010 7:00 AM T 0.0 M 0.0 M This "trace" may be merely an accumulation of dew, since I replaced the funnel and inner tube in the gauge yesterday, and there has been fog overnight. Although recent warm temperatures have thawed the ground at the surface, it remains frozen below as a result of the long frigid period which preceded. So solid surfaces (such as pavements and soil) are thoroughly wet, while dead vegetation remains dry.

2/6/2010 7:00 AM 0.57 0.8 M 0.5 M Intermittent light to moderate rain fell through the morning and early afternoon, changing rapidly about 3pm to snow, which continued to fall for some hours. The contents of the gauge this morning was mostly rainwater, with some slush from the later snowfall. Some wet snow was stuck to the *outside* of the gauge on the upwind side. In many places, snow depth was less than is reported, because of variable amounts of melting on contact with different surface materials. The reported depth of new snow is the deepest that could be found, rather than an average that would ordinarily be reported, because the snow was too wet to drift and variations in depth are in these conditions more the result of variations in melting than of variations in what fell.
