Temp not rising here yet but seems to have leveled off at 16. The current 15.9 is the low for the day, but it's been close to that for a while.

Temp here is down to 17. First teens of the season. Took long enough. What a little snow cover can do ...

We leave the tree and outdoor lights going until my son's birthday, which is this coming week. It's a family thing. One of the plusses is finally having snow on the outdoor tree. I have a 15 foot dwarf Alberta spruce (the kind that aren't supposed to get that big) that I wrap with white lights. Looked great last night.

Just based on my own experiences with my standard 4" COCORAHS gauge, which might not be a valid comparison, they catch rain a lot better than snow. At the time I measured 9.1" on the ground yesterday, there was an uneven (stacked higher on one side) 2" of snow in the guage (I had removed the center and top prior to the storm). I'm not sure what the physics/mechanics of this is, but I've seen it many times. I emptied the paltry catch from the guage and used it to get a clean core of the snow on the ground which melted down to 0.65", a hair under 15:1. The snow depth here this morning was 6", so that 15:1 stuff compacted quickly.

Jeez, what a start to the year. Prayers that things get better for you and family.

January 1999 was meh. There was some very cold low level air around at the beginning of the month, not much snow, and mostly rain or ice. The most interesting thing that happened all month was a localized OES band on a northeast wind off LIS that persisted for hours and deposited at least 6 inches of pure fluff in the Sands Point / Port Washington area. No place else was effected. There was a big ocean storm in late February 1999 that backed in enough to drop snow ranging from 13" at Montauk to almost nothing in Nassau County.

Fair play. When you average them out, we do quite well. Just not as flashy as some people think.

Wound up 14.9:1 SWE ratio here from a melted core. 9.1" snowfall, 0.65" LE

I'm seldom in the regional jack zone, but I just assumed that it is statistically unlikely to be in it for any one place for a given storm. February 2003, January 2005, Feb 2006, Dec 2009, late Feb 2010, January 2015, and January 2016 all come to mind as notable storms where we weren't close to local jackpots. Notable storms where we were in the jackpot zone include 3/15/99, 1/27/2004 and 2/14/2104. There are many others among smaller snowfalls. There were a couple of notable storms where we were reasonably close, including February 2013 which was a real good one to be reasonably close to.

2N Smithtown, NY 9.1" as of 8:30am Still snowing 28°

Eyeball measurements not worth much, but FWIW, eyeballs say about 6" on the picnic table and we're about to get into a real nice looking band. We take.

There was some sort of boundary in the area that I wouldn't have expected to fluctuate towards the colder at that time. I looked at a PWS just west of ISP and it did not bear out the ISP readings, but looking at another PWS just east of ISP, it did: https://www.wunderground.com/dashboard/pws/KNYHOLBR17/table/2022-01-5/2022-01-5/daily Windshift and rapid cooldown was probably not an ASOS error. So there's how far west the initial push of warm air got before backing off. We didn't get to freezing until after 8:30AM here. It was dicey on the steps in front of the house, although the road seemed fine. Up to 41 as of 12:40.

What's behind the windshift and 8 degree temp drop between 5am and 6am at ISP?

What's a newspaper?

I noticed Millville at 5 (with calm wind) at one point this morning.

On the lower resolution models, a lot of the island models as ocean.

I had -2 on 2/14/2016.

Technically, it was sub 20 here this am (19.7) but I record that as 20. Does anyone record without rounding? If the decimal is .5, I round to the even number. Keeps things more even

Sounds right. The minimum temperature here (Smithtown) on 1/4/2014 was 0. The previous day (1/3/2014) had a min of 8 and max of 16 with 8.5" of snow. Not the highest snowfall in the area.

Mind you, 1972-73 was a strong El Nino, but there was this during the winter of NYC's lowest seasonal snowfall: https://www.weather.gov/ilm/Feb1973Snow At least one location in Florida got more snow that day than NYC did the entire season.

January 4, 2018:

So where is the warm air for there to be liquid raindrops that freeze, fall, coat in more liquid, etc? BTW, I could stand another of those too. Almost 30" here. 30+ nearby.

How does it work that the column did not have enough warm air for there to be sleet, so that's why Ryan thought it was actually small hail from convection? Not saying it isn't so, but I don't understand how that would work.

The dry air issue has been discussed enough, but looking at the bottom of this radar view from KENX (Albany), you'd think LI got clobbered today: https://weather.cod.edu/satrad/nexrad/index.php?parms=ENX-N0Q-1-200-100-usa-rad Fun stuff.
