It would be from WAA front end snow due to the high to the north. Either way I don't expect much of anything but that would be what would produce snow.
The storm is so awful i'm rooting for the record, would be more interesting than 0.10 washed away by rain. If it was like an inch it would be worth it.
Let alone the fact every model has NYC at around 35-36 at the start of the storm, thats not a signal for accumulating snow midday. Depends also if it comes in strung out and messy or like a wall, like a wall would provide some evaporational cooling.
Might actually have a better chance of a flip to snow on the backend of storm 1 in say Westchester and Rockland than any meaningful frozen precip from storm 2.
The Wed storm already is pretty much a cutter with some frozen precip at the start. The Monday storm is actually more favorable for CNE/NNE imo as there is stronger secondary development.
The strength and placement of the high to the north is the only variable here that could make the start more interesting but I’d lean toward the scenario you described above.
How much is needed to be considered measurable? I’m partly confused about this whole 0.0 thing because parts of the city saw a tiny bit of snow in mid December.
The pattern stays active through early February and it's a little cooler so probably thats our best chance although this winter everything that can go wrong seems to go wrong.
The 12Z Euro keeps the low south of Michigan and NYC starts snow on Wed. Can't believe we are tracking a storm that will be at most an inch of slop to rain but thats winter 2022-2023.
