Discussion OBS for minor to possibly moderate impact winter storm interior 4A Tue - midnight Tue 12/2/25, may bring first measurable snow-sleet to coastal areas including NYC

[MANDA]

Thinking along the lines of 2-4" for my location and elevation.  Expect main / well traveled roads to have few if any issues as they will be heavily treated.  Side and back roads I would expect issues.  Not a bad start to the season and no matter what the first half of December looks to average solidly below normal.

Probably some white rain at the onset, maybe even a little grass accumulation at best but will all turn to rain with temps near 40F.

Agree

All rain event for the coast

This probably is a snow event for NYC in January, even without a true high to the north but 12/2 is too early for that setup.  The temps are cold enough but the DPs are not due to the airmass in place

I believe a good comparison would be December 5/6 2009. Offshore track resulting in hours of white rain. Areas just north and west had a moderate accumulation.

Actually a perfect benchmark track.

Again no accumulation for the coast.

Forgot about that storm, that was one of the craziest cases I remember where the setup was almost perfect and it rained.  Many of us at that point felt we were headed for another 97-98

I lived in Norwalk CT at the time and it snowed the entire time yet did not accumulate at all.
