Possible Light Snowfall (1" - 4") on Tuesday Dec 23

NYC needs 0.2 to go above 3 inches, Kalshi odds only 45 percent for December.  Seems low to me

I’d give them a decent shot now but we got a ways to go.  This system will probably have two maxes.  The area that gets hit from the initial warm advection and clipper and then from the developing surface low offshore.  Someone in between will get the shaft.  Right now the prime shaft zones may be places like central MA down through CT and central to eastern LI.  It’s a case where Morristown could see more snow than New Haven

Literally +110 odds lmao

We all know there could be 3 inches on the ground and they’d measure it as a trace

[North and West]

Not to mention, being December 23rd it will be practically the best sun angle possible, especially at night.

are you sure? We will already be past the solstice, so it’s sun angle city from here on out.

it's going to most likely be white rain!

Definitely with the low heading north of the area. Would be white rain to start And then dry slot . And considering central park is notorious for under measurement, it would be like nothing ever fell

To play devils advocate, LGA has the same low measurement. They both seem low, but support each other

Maybe

Nam was colder and further south

RRFS is even further south than 12z. Precip is not quite as robust as 12z but it's basically all snow for our area except maybe ELI. Quick burst then the forcing quickly fizzles. Not much snow for SNE. Good sign to see the south shift but we don't want to lose the signal for heavier banding.

The RRFS actually has additional snow showers for the area (esp N) Tue night. Doubtful since there's not much support and the RRFS isn't reliable at the end of its run. But if the tight thermal boundary stays close to our area and we remain on the cold side, there will be chances for snow. Different models at different times have shown snow chances every day from Tue through Fri. It depends on the track of the very minor shortwaves in the longwave flow and how they interact with the thermal boundary. At some point next week I suspect we'll switch to warmth... but it's not certain yet.

Rgem further north but its in the long range.

The RGEM wasn't further north. The shortwave was actually a hair south. But lighter precipitation and different distribution of precipitation screwed the impression.

ICON and RRFS highlighting the potential for a narrow area of heavier banding. Some indications of possible 0.1" liquid per hour. It probably wouldn't last too long as it shifts east, but it could put down a quick couple of inches if we're lucky.

I still think any of these solutions is possible since we are still closer to 60 hours from the event - we are right on the border of the cold enough air and significant enough precip - could go either way.......
