| 2026-02-20 | 10:00 AM | 0.69 | NA | NA | 0.5 | NA | | Morning rain. Waited until rain ended, so 0.69" is the storm total. To compare against other locations with earlier obs times, you'll need to compare their 2-day totals. Ground still has patchy snow cover from the Jan 25 storm, roughly 20% snow covered up to around 2" in depth (not including plow piles). Accounting for the patchy snow cover, I am estimating 0.5" snow depth as trace (T) is clearly inadequate, it is more. |
| 2026-02-19 | 8:20 AM | 0.01 | NA | NA | 1.0 | NA | | Ground still is around 60% snow covered with depth up to 3", so I'll go with an average of 1" including the bare areas. The streak is now 26 consecutive days of snow cover, since the big Jan 25 storm that brought 2" of water, much of which fell as sleet on top of the snow before the precip changed to sleet. |

I took 3 core samples from representative areas and got 1.56", 1.45", and 1.29". Top of crust was rather uniformly 5" above ground although there seemed to be variability of how much snow was underneath this crust. A few places had different depth, ranging from 3.5" to 6.5" but those were outliers, almost everywhere it was very close to 5". With rain tomorrow, we'll see whether the snowpack holds the extra water in place or if melt runoff plus rain runoff prevails. |

Measuring now that precip appears ended because I am not trapsing through the snowcrete to reach the gauge in the backyard in 50 MPH winds in the morning - calm and mild (26 deg F) now before the arctic front blasts in later overnight. Gauge (outer cylinder) depth around 1/4 inch, melted down to just short of .02" when funneled to inner cylinder (after bringing the sample inside the house). Sticking ruler into the previous ruler holes in the snowcrete show depth ranging from 5.5 to 9.5 inches with 6.5 to 7.5 most common, average and median are around 7 inches now. Afternoon days with a little liquid in the street gutters reveal melting in progress as it has been a little warmer with several hours of temperatures near or above freezing. |

| 2026-02-03 | 9:45 AM | 0.00 | 0.0 | NA | 8.5 | NA | | It's been more than a week and the several-inch-thick ice crust has hardened even more and is impossible to break through without a long sharp instrument - stomping and heel kicking does not break through. I used a screwdriver with a 12-inch blade (e.g., not counting the handle). I was able to dig down to the grass and stick my ruler in. It appears there has been hardly any melting (too cold) or sublimation (too glued, not like loose snow) or compaction (too rigid) - it is the same as immediately after the storm ended. Conditions are unsuitable for collecting core samples, so I can't vouch for the water content but likely not changed much. |

| 2026-01-26 | 9:30 AM | 0.90 | 3.0 | 0.90 | 8.0 | 1.97 | | Note yesterday's reading was at noon so the storm partitioning among the two days may differ from other stations. Today's report is mostly sleet. Storm total in gauge was 1.97" melted. Cores today had 1.82" in typical spot (8" depth) and 2.41" in deeper spot (10" depth) and expect no melting in cores (frozen ground and air temps in teens (deg F)). Found 3" depth in the gauge (no inner cylinder of course) and also 3" in the area on the deck I swept off at the time of yesterday's obs (serves as my snowboard). That makes the storm total at least 10" (e.g., yesterday measured 7" in gauge column of outer cylinder but might already have been a little compressed, plus 3" additional in today's obs). Going with 8" for snowpack depth based on measuring predominantly 8" in yard, with a few spots ranging from 6" to 10". |
| 2026-01-25 | 12:00 PM | 1.07 | 7.0 | 1.07 | 7.0 | 1.07 | | Snow started mixing with sleet in the morning by around 9AM, with increasing fraction of sleet over time, and precipitation is still continuing, expected to last much of the day. Outer cylinder of gauge had 7" depth, melted down to 1.07" including volume of 3 dead ants. Yard mostly had 6" though I found a few spots with 7" including on the deck. Likely compression due to sleet on top, so I do not have a proper measurement of snowfall depth. Everything was frozen well before the snow started and temperatures are still in the teens (deg F), so nothing lost to melting. |

Snow is melting quickly, max was approximately a half inch on the deck railing which was below freezing after the past few cold days and nights. Snow never completely covered the grass (not bare patches, just not deep enough to cover). |

Several other periods of sprinkles/light rain from a series of small convective bands through the afternoon.
