Final Smithtown stats for the weekend blizzard: Snowfall: 16.4" Water equivalent: 1.62" Temperature range during the blizzard from 29 at the start down to 12 late Saturday morning. So much for high ratios. I think there's some local effect here that exacerbates the shredding of dendrites. Might be proximity to LI Sound on a bit of an ENE facing hill above the Nisseqogue "fjord". At the surface, it was rather windy but we've had plenty worse. The biggest winds were when we spent an hour or so in subsidence between two nice bands. Other than that, we were on the plus side of banding for much of the storm. Trying to wrap my head around why we're just about always a local min during these windy snowstorms.

Top snowfalls in Smithtown, NY since December 1995. While technically, this weekend's was 6th on the list, I'd rank it a little lower, maybe top 10 or top 12. Great storm, but I guess we're getting used to them. 1 Feb 8-9, 2013 27.0 2 Jan 7-9, 1996 22.3 3 Feb 16-18, 2003 18.8 4 Jan 23-24, 2016 17.5 5 Dec 19-20, 2009 17.0 6 Jan 28-29, 2022 16.4 7 Jan 11-12, 2011 15.8 8 Jan 31 - Feb 2, 2021 15.8 9 Dec 5-6, 2003 15.5 10 Jan 26-27, 2015 15.0 11 Jan 26-27, 2011 14.5 12 Feb 10, 2010 14.5 13 Jan 22-23, 2005 14.4 14 Mar 21-22, 2018 13.6 15 Feb 13-14, 2014 13.5 16 Jan 27-28, 2004 13.5 17 Feb 11-12, 2006 13.3 18 Mar 05-07, 2001 12.2 19 Dec 26-27, 2010 12.0 20 Feb 25-26, 2010 12.0 21 Apr 9-10, 1996 12.0 22 Feb 9, 2017 12.0 23 Mar 1-2, 2009 11.5 24 Dec 19-21, 1995 11.3 25 Dec 30, 2000 11.0 26 Jan 4, 2018 11.0 27 Mar 14-15, 1999 9.8 28 Jan 7, 2017 9.5 29 Feb 5, 2016 9.4 30 Mar 7-8, 2018 9.1 31 Jan 7, 2022 9.1 32 Jan 22-23, 2014 9.0 33 Feb 3, 2014 8.8 34 Feb 2 - 3, 1996 8.5 35 Jan 2-3, 2014 8.5 36 Feb 1-2, 2015 8.3 37 Feb 7, 2021 8.1

It could (either accreting or melting), but in that scenario there might be enough air movement to carry it off without affecting the sensor. I'm sure somewhere someone has studied this for some reason, but it's way beyond my pay grade.

Here's a thought. If the ponds are still freezing (i.e.,the ice is thickening), the latent heat release from that freezing process has to go somewhere.

Lot sizes. Much higher percentage of rooftop snow on the lawn with a 60x100 lot than an acre lot.

I find it much harder to remember those self serving names. It's much easier to remember 2/8/2013 than to remember Juno or Junius, or whatever the heck they called that one.

Young guy with a truck and a snow thrower just snorkled up and knocked on the front door. I told him that I had the snow removal covered. He said "you're going to do it?" I said yes. Then he said "Your driveway just ate me". I almost changed my mind. We'll see how it goes. There will be libations afterwards.

From your lips to God's ears, but no, not going to happen. We can dream.

I'm sure there were multiple factors. There must have been some other source of convergence other than the usual frictional convergence on the north shore. But the sound may have helped. dT around 14 or 15° C is more than enough for some enhancement.

I'd have wanted better for being on the windward side. It was primarily a south of 495 enhancement.

Well worth the price of admission!

Jinkies, temp is down to 12° here. Visibility is about a half mile in snow and blowing snow, but lower in the stronger wind gusts.

Just measure on the deck and report it to the NWS.

Lucky you. Spent over an hour doing basically nothing here. Except for the wind which was howling to feed into the surrounding bands.

Southampton has been getting obliterated. Then again, a lot of places have. But here:

Except for the wind really cranking, that subsidence was kinda boring. Back into good rates now Depth on the snow stake hasn't increased since about 9:30, despite having a couple of hours of approx. 2" rates during that time. Safe to say we have at least the 13" on the stake and probably a good bit more. I was happy with my 9am obs, but since then measuring this one is a royal mess. No idea how to get an accurate number now. The stake is near my boards on flat ground in the most open spot I have. My neighbor has more of a hill in front of his house and the "waves" on his lawn look a little like swells on the ocean. My lawn has more uniform snow depth, but clearly a lot of that snow is going somewhere else.

Excellent timing

Like 14 or 15 hours during the Blizzard of 1978:

Two more videos from Smithtown @ approx 10:37am

Nearly 13" here so far. S+, 17° Some video:

I measured snowfall at 9am (three boards) and averaged out 11.4". Placement of the boards must have been pretty good because there was only about an inch difference between the high and low measurement. It's been pounding pretty good since then and looking out the window, we're past 12" on the snow stake. 10am temperature is 17° Snowflakes have been smallish. I doubt ratios are much better than 10:1, but will have to figure that out later. Smithtown, NY 40.88, -73.21

Alright, I went out for one more observation before bed. 3.5" as of 1AM (1.1" in the past hour). 28° , moderate snow / blowing snow 3.5" storm total Smithtown. NY

This live webcam reminds me of driving at night in a snowstorm. The kind when you get home and close your eyes and still see snow in the headlights for about an hour:

Smithtown, NY Midnight (12am 1/29) 28°, moderate snow, Viz ~ 3/8 mile, Can hear the wind gusts through the trees from inside. 2.4" storm total. Averaging from 3 boards. Liking what I am seeing on radar and out the window...this has been more fun since I stopped looking at models. I'm thinking it even looks kind of promising for the HV, especially east of the river but possibly west too...unless that is going to get eroded by dry air. Gonna turn in soon and get a few hours (if I can sleep).

Smithtown, NY 11:30PM 29, moderate snow About 1.5" down Getting windy. Occasionally gusting to around 25 mph.
