Observation Date Observation Time Precipitation Snowfall Snowfall SWE Snow Depth Snow SWE Notes
10/1/2016 7:00 AM 0.21 M M M M Davis VP reports 0.20", forecast calls for days of on and off light rain.
10/2/2016 7:00 AM 0.05 M M M M Davis VP reported 0.06". The last tip was recorded at 0010. It was probably very lightly drizzling then, and it is now too. It was raining yesterday morning, so I'm just going to skip the duration information.
10/3/2016 7:00 AM 0.02 M M M M Duration info doesn't reflect the drizzle that occurred on and off during the day.
10/4/2016 7:00 AM 0.39 M M M M Davis VP reported 0.40"

10/9/2016 7:20 AM 0.05 M M M M Light rain, from moisture fed from hurricane Matthew. A cold front will keep it mostly offshore, there shouldn't be much more today.
10/10/2016 7:00 AM 0.47 M M M M Davis VP recorded 0.53". Gauge total for event 0.51". Quite a bit more than forecast

10/17/2016 7:00 AM 0.00 0.0 M M M Showers in the area, but I think we didn't even get a trace. Dew would have wiped out any trace of a Trace.
10/18/2016 7:00 AM 0.03 M M M M Light rain overnight. Davis VP recorded two tips, at 0120 and 0450. I'm skipping the duration information.
10/19/2016 7:00 AM 0.01 M M M M Much ado about almost nothing. Fog, mist, sprinkles all day and night related to a stalled warm front added up to a single tip of the Davis VP at 0100. The day dawned with clear sky, the warm front managed to scour out the valleys.
10/20/2016 7:00 AM 0.00 0.0 M M M
10/21/2016 7:00 AM 0.12 M M M M Davis VP also reports 0.12". Rain has been in two light periods with uncertain start/stop times. First, tips at 1650, 1720, and 1800, then resuming with the first tip after midnight. The closest thing to steady rain was a single tip in three consecutive 10 minute periods, which are hardly worth calling heaviest.
10/22/2016 7:00 AM 1.04 M M M M Davis VP reported 1.07". All but 0.05" was between 1450 and 2340, but it was pretty much wet for the whole reporting period. The heaviest rain band was a little east and ways south, as the map will show, I'm sure. The air pressure is notably low, 29.23".
10/23/2016 7:00 AM 0.09 M M M M Davis VP also says 0.09, and reported tips between 0800 and 0350. Nothing worth calling heaviest. Temperature trace shows a FROPA at 0700 yesterday a dip around 0350 tip, supporting the notion that was end of the rain.

10/28/2016 7:00 AM 1.08 M M M M Davis VP recorded 1.24", surprisingly high given the light wind. No snow. My 1.08 is from gauge reading 1.30" at 0800 minus 0.22" per Davis from 0700-0800. Note that nearby site NH-MR-43 reports 1.31" at 0755.
10/29/2016 7:00 AM 1.02 M M M M Davis VP: 1.04". Total CoCoRaHS gauge for event: 2.26". Rain ended with a slow taper, so ending time of 1730 is the best I can do. There was rain to the south during my commute around 1900 and drying pavement north of Concord.
10/30/2016 7:00 AM 0.08 M M M M Davis VP says 0.07", reported tips at 0810, 1250, 1430(4!), 1450. However, it was gray and wet the whole day.
10/31/2016 7:00 AM 0.06 M M M M Davis VP agrees. Rain was associated with a secondary FROPA that is bringing us some sunlight for the first time in a few days.

Air temp has been 33.x for the last six hours or so, surface temp for car windshield and roof is below freezing. The car roofs are covered in lacy frost, CoCoRaHS gauge funnel was frozen to the out tube, just a little ice in the inner tube.

Will shift to regular rain soon enough, I hope. There's so little solar heating this time of year that we may have to wait for the warm front to scour out the valleys.
11/30/2016 7:00 AM 0.61 M M M M Davis VP said 0.66". The day started with a little freezing rain with the usual car rollovers and whatnot, but things were okay for later commuters.

1/24/2017 7:00 AM 0.60 1.1 0.52 5.0 M Awful stuff overnight. The snow board had a little sleet, then some mixed with freezing rain, then dry sleet. The bottom 1/3 is basically ice, the top 2/3 can be scraped off.
1/25/2017 7:00 AM 0.05 0.0 0.00 5.0 M There were showers of all sorts around all day, but they didn't reach the Merrimack valley. More widespread rain finally made it in during the evening, the timing below is derived from the period of higher dew points because the Davis rain gauge has ice and sleet so its timing is all wet.

2/7/2017 7:00 AM T 0.1 T 5.5 M An annoyingly measurable amount of snow fell this morning. The 0.1" of snow is more "surface texture" than ground cover. It weighed 1 gram, on a scale with 1 gram precision, that's 0.05" +/- 0.025" SWE, so I'm calling it a trace, and could make a good case for the new snowfall being a trace also. Instead, I've left this morning's snow in place and will subtract 0.01" from tomorrow's report. With snow changing to rain, it will be tough to get right anyway.
2/8/2017 7:00 AM 0.71 2.4 0.60 7.5 M I forget when the snow started and was asleep when the freezing rain ended so I'll skip the duration info.
2/9/2017 7:00 AM 0.00 0.0 0.00 7.0 M Yay, today's storm held off until just after 0700, so it will all fit in tomorrow's report.

2/11/2017 7:00 AM 0.08 1.6 0.08 12.0 M Radar says the snow shield is past, but there's still insubstantial S-- happening. It will be little more than a trace. Okay, perhaps a little less than a trace. I'll call it a trace tomorrow, though a nor'easter will be starting around then and may make that moot.
2/12/2017 7:00 AM 0.03 0.2 0.03 11.0 M Snow continued past yesterday's 1.6" with another 0.2" over some 6 hours of very light snow.
2/13/2017 7:00 AM 0.81 8.1 0.81 19.0 M Less snow overall than expected. Total weight on snowboard 166 grams, total weight in gauge 167, from three samples. Remarkably close! And despite a range of snow densities, the overall fluff factor is 10.0. Still very light snow, so we're not quite done.

I thought the rain had finished at 1320, the radar was clear around 2000 when I reported 1.09" total to the NWS (station ME74), but bucket tips were recorded at 2330, 0010, 0340, 0600.

Despite the chilly air the rain ushered in, we had a small thunder storm bring 0.06" between 1900 and 1920. The forecast said there was a 10% chance of rain, but nothing about Tstrms.
5/2/2017 7:00 AM 0.76 M M M M Davis VP recorded 0.77". The rain was from a squall line that had been thunderstorms but had lost that activity given the time and temps in the 40s by the time they reached New Hampshire. The heaviest precip was 0.24" in 20 minutes, a decent second peak was 0.15" starting at 0120 for 20 minutes.
5/3/2017 7:00 AM 0.03 M M M M We had drizzle in the first part of the day, showers in the late afternoon as a cold front came through, all resulting in three bucket tips, at 0830, 1150, and 1750. Hardly rainy, but hardly dry.
5/4/2017 7:00 AM 0.01 M M M M Davis VP didn't count it, but we had drizzle and a little rain sometime in the afteroon.

5/6/2017 7:00 AM 1.00 M M M M A statistical anomaly - exactly 1.00". Inner tube full, outer tube dry on the inside. Davis VP recorded 1.04".
5/7/2017 7:00 AM 0.12 M M M M Davis VP reported 0.11". Rain on and off, but a good break after 1430 until a line of showers came through just before sunset with clear sky behind. That left an intact sunset of maximum arc that was seen throughout much of the state.
5/8/2017 7:00 AM 0.12 M M M M Davis VP reported 0.12" too.
5/9/2017 7:00 AM 0.01 M M M M Davis VP reported one tip at 1000. We had a little drizzle and brief showers throughout the day. It was raining when I left for work around 0940, dry 7 miles later in Concord, damp road on the other side of Concord with patches of blue sky.

We are in a dry area now, so the end time is mostly meaningless. Heavy precip period was 0.20 + 0.19 + 0.10 + 0.07", more than 1/3 of total.
5/27/2017 7:00 AM 0.05 M M M M Light rain throughout the day, but it's tough to assign start times. Davis VP reported tips at 0830, 0950, 1210, 1810.

5/30/2017 7:00 AM 0.06 M M M M Davis VP reported 0.05". Light rain, difficult to have accurate start/stop times, so I just used Davis times. Extend both by an hour or so.
5/31/2017 7:00 AM 0.20 M M M M Davis VP reported 0.19". First raindrops were at 1900, first bucket tip not until 2210. The tail end was likely as drawn out, but I'm going with the last bucket tip for that.
6/1/2017 7:00 AM 0.10 M M M M Davis VP reported 0.11". Two tips were outside of the the squall line passage at times it probably wasn't raining, so I'm using them for timing info. OTOH, the rain tapered off slowly, so it's unclear when it really stopped. Most for the rain, 0.08" fell between 2000 and 2010.

6/7/2017 7:00 AM 1.68 M M M M Davis VP reported 1.65". Gauge total with yesterday is 2.31", a lot more than I expected. (NWS expected 0.50" - 1.00" for the day and night.)
