1/7/2015 7:45 AM 0.12 M M M M Total snow depth from yesterday's storm: 4" on table on back deck (don't have a snowboard, so not entering it as an official number); depth measurement taken about 1:00 pm on 1/6, after end of snowfall
1/8/2015 8:00 AM T M M M M There was a very small amount of snow in the gauge, but it's possible that it was from blowing of existing snow rather than anything new falling.

1/13/2015 8:00 AM 0.31 M M M M Measurement the previous day (and therefore emptying of the rain gauge) was made later then usual, and while precipitation was falling, so this number is low compared what actually fell in the previous 24-hour period.
