Snow fell continuously all day yesterday until sometime mid-evening. Heavy snow accumulated to a depth of 22-24" in my driveway, despite my having shoveled off 4.5" before 3 AM. I swapped out the CoCoRaHS gauge at 6:30 PM when it was filled nearly to the brim with snow, to avoid overtopping it. The melt-water from that load was 0.59". The remaining snowfall must have been gentle, because the melt-water load at observation time was only 0.02". IQAir monitor: Temp = 23°F, RH = 93%, AQI = 17, CO2 = 444 ppm. Calculated dew point = 21.3° F. |
| 2026-02-23 | 8:00 AM | 0.65 | NA | NA | NA | NA | | First flakes of the big storm noticed about 8 PM. During initial shoveling from 1:30 to 2:50 AM, the snow depth on the driveway went from about 3" to about 4.5". There were occasional gusts, but it was not generally very windy. I swapped out the CoCoRaHS gauge at 2:30 AM to avoid overtopping it with snow. The melt-water from that load was 0.32"; that is a high-confidence measurement. At 2:30 AM, IQAir monitor: Temp = 29°F, RH = 99%. Our street, a tertiary state highway, was plowed for the first time at 3:15 AM. The real high winds kicked in sometime after 3:30 AM. At the 8 AM observation, the wet sticky snow was piled high above the top of the gauge, but there was lots of air space below that cap, therefore I have no confidence that the extra 0.33" measured from that load captures reality. |

| 2026-01-19 | 7:45 AM | 0.76 | NA | NA | 5.5 | NA | | Snowing gently, small flakes. Every time I looked outside since yesterday's observation, it appeared to be snowing gently to moderately, small flakes, with little to no wind. All tree & shrub branches are heavily laden with wet snow. House lights dimmed occasionally and briefly around 8 AM, I assume due to snow on power lines. No snowboard, but I measured 5.5" snow on a flat surface at observation time. While waiting for my gauge snow to melt before this submittal, I noticed that the snow seemed to have stopped about 8:30 AM today, 1/19. IQAir monitor: Temp = 32°F, RH = 87%, AQI = 58, CO2 = 437 ppm. Calculated dew point = 28.6° F. According to my IQAir monitor, the average hourly temperature has been 32.0 or higher since 5-6 AM on 1/18, therefore the entire duration of the snow event. |
