Minimal accumulation changes at this time from last night, lowering the values ever so slightly by an average of 0.50".
They have also raised the temperatures up by 1° meaning for the NY metro area which will see 35° there will be less initial accumulation of snow as it will melt instead, and there may be slight mixing with sleet/rain. Slightly more will accumulate on onpaved surfaces.
However the bigger change is how the storm will be moving, which is slightly more south. This means that NYC may see less with long island (especially east) still seeing similar values.
The GFS moved the storm 10-20 miles SE, the NAM is remaining well south with far less accumulations, and the EURO has started to also track south slightly.
The common theme is a first snowfall time on Sunday between 11am-1pm, ending at night between 6am-8am
