Addendum: December 2025 was the 5th coldest out of the past 31 Decembers here. It didn't even seem that cold, but certainly we didn't have the extreme warm outlier days that seem to have become prevalent in December. 12/25 average was 33.1, December mean is 37.2. Here are the 5 coldest: December 2000 - 29.6° December 1995 - 30.7° December 2010 - 32.2° December 2002 - 32.9° December 2025 - 33.1°

On the heels of yesterday's "record breaking" New Years Day snowfall, here are some more stats from the current winter season in Smithtown: The period of record for snowfall is 10/1/1995 through the present. The old daily January 1st record of 0.1" was the lowest daily record of any date between November 30 and March 25. Yesterday's 0.3" of snowfall shattered (tripled ) the old record set on New Years Day 2010. Here are all New Years Day snowfalls in Smithtown since 1996: 1997 - Trace 2006 - Trace 2010 - 0.1" 2014 - Trace 2020 - Trace 2021 - Trace 2026 - 0.3" Snowfall this season through 1/2 is 13.4". The December mean temperature was 33.1° and monthly snowfall was 13.0". Thus far we have had 11 days with at least a trace of snow, 7 days with measurable snowfall, and 3 days with at least 1 inch. Total precipitation for December was 4.33". Total precipitation for 2025 was 39.46" (8.34" below the 13-year average) Finally, the only other day in January with a daily snowfall record below 1" is January 13 (0.5" in 2000). We might have a shot at breaking that this year.

Same here. Was that you on mping near that same location?

I assume he's 12 years old.

Perfect fetch for LIS effect snow into the north fork right now. @wthrmn654 might wake up to a surprise. 21⁰ with light snow in Smithtown at 2am. Temp had been down to 16⁰ earlier.

Where has LongBeachSurfFreak been?

Right on the edge here. Those annoying models that said we would be right on the edge were right. How annoying.

Frequent light to moderate snowfalls reminds me of when I was a kid. It's not terrible if the warmups aren't too much. One of my earliest memories, which may have been exaggerated by the years, was of it seeming like every morning waking up to a new snowfall. Mid to late 60s, maybe early 70s it would have been, probably more than 1 winter. Don't care whether that was quite the reality, I'm hanging on to that memory... and 1978.

Philly looked like it was getting skunked too with the snow shield northeast of there, but then it backed up just enough to put them in a heavy band near the edge and they got 8".

Snowcover is about 50-50 here, but not all of the covered area is even an inch, so I'm going with a trace. But it still looks nice in places.

It's too soon to pin down events or dates, but not too soon to be looking at these: https://www.tropicaltidbits.com/analysis/models/gfs/2025122912/gfs_mslp_pcpn_frzn_eu_40.png

I believe that FAA guidelines for airports still include wiping board every 6 hours, but all others pay cash. NWS observers, coops, etc., should clear the board once per day and report the max depth on the board between clearings. Stuff lives forever on the Internet and there's a lot of confusion, but I think that is the current practice. Personally, I wipe my boards at midnight, which is out of sync with my ~9am rainfall observation, but that's probably for the best here.

Just had a light rain shower at 31⁰. I assume it iced on some surfaces, but not enough precip to do much harm.
