10/10/2018 7:00 AM 0.08 T M T M freezing fog, freezing rain, light snow
10/11/2018 7:00 AM 0.04 0.2 M T M Wintry mix, light snow. New snowfall estimated from approximate ground measurements (put snowboard out during snowfall, so all snow that landed on board melted because the board had not reached temp equilibrium)

10/14/2018 7:00 AM 0.09 1.9 0.09 2.0 0.09 Freezing rain turned to snow overnight. Initial snowboard measurement exceeded rain gauge measurement (0.14), but felt there may have been error in my collection method (first time making this measurement). Took another measurement on nearby surface and got the same value as the rain gauge measurement, so reporting that value (0.09).
10/15/2018 7:00 AM 0.07 1.4 0.07 2.0 0.13 Reporting snow board water equivalent for daily precipitation. Gauge measurement (0.05) is not representative of true precipitation due to very light, dry snow blowing out of gauge.

10/31/2018 6:47 AM 0.45 3.4 0.45 3.5 0.45 Daily total reported from melted core measurement from snow board. Gauge reported only 0.34", likely due to blowing snow. Lightly snowing at the time the measurement was taken.
11/1/2018 7:00 AM 0.02 0.2 0.02 2.0 0.24 Snow remains on north-facing slopes and shaded surfaces. New snow total measured at 7:45 on previous day before leaving for work. Actual amount of new snow may have been higher (melted by the end of the day and could not get true measurment). SWE for new snow is estimated to be the same as the rain gauge measurement.
11/2/2018 7:00 AM 0.00 0.0 M 1.5 0.17 snow remains on north-facing slopes and shaded surfaces
11/3/2018 7:05 AM 0.04 T M T M Rain/snow mix. No new snow stuck to ground, but some patches of snow remain on north-facing slopes and shaded surfaces.

11/15/2018 7:00 AM 0.00 0.0 M 2.5 0.29 Initial measurement of average total snow depth was 2.5" with a SWE of 0.34". Core sample was taken right next to core sample from previous day which had a SWE of 0.32" (which was 0.05" more than the previous day measured in a different location). Being the second consecutive day with a decrease in snow depth but increase in SWE, I took additional measurements to investigate. The conclusion is that because much of my yard is sloped, higher SWE is found at the bottom of the slope and retaining walls, likely due to pooling/settling of melt water from above. An effort will be made to avoid measurements at the bottom of the slopes and retaining walls in the future.
