Notes: Not getting much sleep due to this storm. Intensity seems to be letting up. In the last nearly 2 hours the total depth of snow on ground only increased by one inch, but the area that I had shovelled down to bare ground at 11 PM had about 3" new snow -- so total thick pack seems to have begun to settle already under it's own weight. Snow crystals continue to be small but not us much riming.

Notes: Snow started around 1:45pm; it was 28 degrees. Small round hard pea size snow fell, and by 2:30pm the ground was covered solidly with snow, but not in inches. It was snowing every time I looked outside, all day. After sunset at 6pm there was almost 4 inches. At 9pm there was 9 inches. At 11:45pm, time of this report, there was 12 inches. When I went outside to measure the snow, the tree next to my deck dropped a ton of snow; I guess it is too light to hold together on the branches. It is very light snow and you could brush it with a broom. The deepest part is 15 inches; I did not go out into the middle of the yard to see if it was different. On the railing it was 12 inches. This report covers from 1:45pm to 11:45pm=10 hours. It is still snowing, enough to make me wet when I went inside. I took an additional measurement to confirm, as the gauge was overflowing with snow and I wanted to make sure I had it right.

Most snow has fallen straight down so far and trees all caked in snow Very light northerly wind now.
