SWE by weighing method. VP2=0.04" (heated TBR) Snowboard was swept clean by wind, so depth is missing. Some areas are blown clear to bare pavement, there are a few minor drifts in the 5" - 8" range.

SWE by weighing method. Snow is extremely light and fluffy. Significant drifting and scouring clear in different areas. Very difficult to measure an average depth on ground. Ranges from swept clear to about 5.5". Rangefinder area did not change from yesterday and is still 0.91"; VP2=0.07" but this light of snow almost certainly evaporated shortly after melting in the funnel area. Consider the "total depth" as a very rough estimate. |

Mixed layers of melted snow and ice present in gauge and snowboard. SWE by weighing method, but also melted accumulation in gauge after removing exterior ice. By melt/tube measurement liquid equivalent was 0.79". There was 0.1" ice accretion on surfaces. I was able to obtain a core sample. Snow was significantly deeper before rain/freezing rain melted it down. Heated Davis VP2 measures 0.62". Rangefinder depth is 0.59" (ice/snow). Start/Stop times are from Hydreon data which does _not_ detect snow. |

SWE by weighing method. Significant variation in depth due to wind drifting. Normal depth measurement area is in the 8-10" range, average of 9" which is what is being reported. Snowboard area is somewhat lower in depth. Rangefinder target area is less being closer to the house/deck. Rangefinder shows only 1.89" which is less than prevailing areas. VP2 shows melted equivalent of 0.19", but this very fluffy snow probably evaporated a lot due to the heater. (this is typical for this type of snow). Time of snow arrival is not going to be accurate due to the lag in melting in the Davis VP2, but was indicated at 12:30 PM yesterday. |

Measured by melting ice in outer cylinder. Snow all melted into water before refreezing. Snowboard was ice-covered and a depth measurement was not possible. Rangefinder depth is 6.22" vs. 5.94" yesterday morning indicates about 0.3" of new depth. Rangefinder target was in the shade in the afternoon yesterday, so this might be more representative. I am leaving the new snow as "NA" since I cannot get a direct measurement. VP2 TBR shows 0.02 for the past 24 hours. |

SWE by weighing method. Tube measurement shows 0.23" but inside wall of outer collection cylinder had significant droplets clinging to the inner wall which would explain the difference. (weighing captured those droplets). VP2=0.16"; NovaLynx=0.27" (don't understand the discrepency). Snow not observed by this observer. Precip stop time from Hydreon data. |

SWE by weighing method. New snow taken on snow board, but there is drifting resulting in total depth from 4" to 11". Averaged total is 8.5", but normal total measurement area is showing around 11". For consistency from day-to-day, 11" is what I a reporting, with the drifting caveat. Snowboard depth is consistently 8.5". Heated Davis VP2 indicates 0.59"; Novalynx is unheated and will not record this precipitation until it melts. (it is currently 0.03"); Snow start time noted at around 6:10 PM last evening. Hydreon recorded 6:05 PM. Rangefinder depth is 1.46", note that this is in a wind scoured area and is very low compared to surrounding areas. (my yard is small and congested and the measuring areas are not within guidelines for spacing from buildings) |

SWE by weighing method. Liquid measurement after melt was 0.18". Snowboard has 2.5" and deepest drift is 25". I am not going to report this in the entries since most of the precipitation in the gauge was sleet and the vast majority of the snowboard and drift are due to wind driven snow already fallen. The sleet pellets were clearly visible when I had the outer cylinder in the snow melter. Sleet is ongoing at observation time. |

SWE by weighing method. Considerable drifting of snow due to winds. I am not going to report "New Snowfall" or "Total" due to uncertainty of the depths. Snow collected on snowboard was 7". Core sample was very wet and heavy from the snowboard and totaled 3.51" (SWE!). From attempting to shovel this, it is very wet and heavy overall. Majority of the precipitation was in the form of sleet and lasted almost all day and into the night. Light snow at observation time. Davis VP2 (heated) TBR shows 1.05" for the 24 hour period. (NovaLynx is unheated and is full of snow). Rangefinder is showing 1.14" depth, but as noted before, this is in a wind scoured area and is one of the low spots. |

SWE by weighing method. Once again, measurements are difficult due to drifting. Gauge catch vs. Davis heated VP2 TBR compare reasonable well. VP2=0.48"; NovaLynx=0.12 but this is unheated and the cone is full of snow. Overall depth taken over a variety of locations that were not affected as much by wind drifting or snowblower action. Readings were 5, 8, 13, and 15 including some in front yard. These average out to 10.25", rounding it to 10.5". There was little wind comparatively so the Rangefinder depth of 8.11" seems OK. Subtracting out yesterday's measurement on the URF of 1.14" results in new snow of 6.97". Snowboard stick measurement is influenced by drifting somewhat and came out to about 8". I am reporting 7" based on the rangefinder. The gauge catch had about 3/4" of ice frozen in the bottom, so it was liquid prior to freezing. Keep these comments in mind when interpreting the data. |

Depth estimated from snow-stick permanently in ground. this area is reasonably representative and is not a drift or wind-scoured area.
I left snow depths as NA for the 4/15 and 4/16 dates. As a side note, I added the commented values (I did measure it, but drifting was severe) together for 4/14 through 4/17. This total ESTIMATED snow adds up to 25" for the entire storm. |

VP2=0.11"; NovaLynx=0.11"; There were a lot of droplets clinging to interior of outer cylinder that were not measured. I used the tube today. The 0.07" reading might be a tad on the low side. Since the VP2 and NovaLynx agree exactly, I would tend to think that this is closer to the actual amount. Old drifts and plowed areas still exist, but there are significant bare areas now and the snow is really disappearing. Start time from Hydreon data. Rain continuing at observation time. |

This must have occurred when we were out shopping, because when we came out of the store the car had fresh water drops on it. Nothing in CoCoRaHS gauge this morning, so I am calling it a "trace". |
