Total rainfall here was 1.21" ending as a brief period of non-accumulating light snow after midnight. The difference between the 4" gage and the ambient was significant; 1.21" in the bucket vs 1.51" with the Ambient. 1.21" stands. If it had been all snow, that would have been some nasty wet slop

I have that problem with the excel files I maintain for my climate records. For my monthly snowfall summary ( https://www.northshorewx.com/ClimateData/SmithtownDailySnowfall.pdf ) I have a 0 for months where there were traces so that the averages don't get messed up (excluding October and May where the average is 0). I keep sheets with the daily data including traces, but I can't calculate an average value for a given date (e.g., December 3) because of all the years that have a trace on that date. As a result, the difference between the actual average seasonal snowfall and the sum of the daily averages for the season in excel is significant; 36.2" vs 41.0"

TLDR: Yes, that's what I would do. To my knowledge, but with low confidence, there is still the "greatest depth in 24 hours" thing. There's so much noise and conflicting guidance on the web, including between different NWS pages, that its near impossible for us mortals to be definitive. Plus, there's different standards for airports/ASOS sites and other users. Not sure if COCORAHS, coops, mesonets, and spotters get the same guidance either. And then there's the measure only at set times sites (cue cpcantmeasuresnow). It's mayhem. I've gone back to resetting at phase changes or between unusual events like separate snowfalls in the morning and evening. Just seems like common sense to me. Otherwise, I do wipe the board at midnight (once per day). I'm amenable to updating my methodology if someone can convincingly show that I'm not doing it correctly.

I think the Dec 1 - 10 mean and median calcs are off. Eyeballing the list, they should be in the 3" range.
-
A lick and a promise from the departing storm. It's snowing. 34.7⁰ I'd play it up like some kind of cosmic irony, but I thought this would happen.
-
1.38" from the ambient, but it's still raining here.
-
Last year was an exception, but that torch thing has been amazingly consistent most Decembers recently.
-
A Dec 14 - 17 warmup would be an improvement on the annual Dec 22 - 25 torch.
-
I just took a walk while it was still dry out. Smells like rain. 39⁰

Looks like some light OES (or freezing drizzle) in the southerly flow, mostly near and east of the CT/RI border. Maybe a few snowflakes, but illustrates the wind direction nicely.

I asked AI to predict the December weather based on this thread. Not sure how/if it weights posts, but it said everything is going to suck forever and then we'll die. In my own experience, there is close to zero correlation between these threads and actual mid to long term outcomes one way or the other (except for potentially the dying part). But at least it's entertaining. The next two weeks should cool the local sea surface temperatures (high confidence).
-
If we have to replicate that period, could we include a 1978 and 1996 in the mix?
-
Ambient 2902 is at 0.46" and counting, but it tends to run slightly high.
-
ISP will probably finish November with a positive temperature departure.
-
12z NAM snow totals look reasonable for the coast.
-
The 12/5/2002 snowfall was a gem.
-
December can't suck forever, but I get it.
-
Gate crashing here because this might be the more interesting thread over the next week. I'm in the Catskills on Wednesday, so there's that. Of course if I'm placing my bet on the LHV, that could be the kiss of death so I am apologizing in advance. Regardless of outcome, it looks like December will keep our attention.
-
The daily snowfall record is potentially misleading (I didn't look to find examples). For Central Park daily snowfall covers 12:00 am to 11:59 pm. There could conceivably be a snowfall approaching 8" that spans both sides of midnight without either day reaching 4". I am sure similar events have happened, although I do not know if it happened within the streak periods.

0.26" north Smithtown

I'd also like to see the original wording of the query, just to further my understanding of how the bot responds.

I was remote for a lot of years before it was fashionable going back to 2006. Not commuting was great, but I actually enjoyed traveling and seeing human beings in an office during that time. These days I'm a self-employed team of 1 (mostly) and all the back office functions are conducted at home, but that isn't really "remote". Low here was 27.9⁰. The 4 hours around 28 or 29⁰ wasn't quite a hard freeze. Maybe there was farther from the sound.
-
28.9⁰ here now. It's been below freezing since 7pm, but flatlined at 29⁰ for the past 2 hours. Stations just to my south are running 26 - 27⁰ and stations just to my north are running 31 - 34 (with a few higher). Just north of that is a lot of relatively warm water.
-
Overnight rainfall here only 0.06". Most of the precip was to our S and SW.
