If this storm is a sub 980 millibars low pressure and tracks over the benchmark with a classic +PNA trough, I don’t think you need northern stream interaction to overcome the wetbulbing effect. Globals always underestimate the thermals which in my opinion is huge, it’s happened too many times to name. Evaporative and dynamic cooling with a sub 980 storm will give New York City a big snowstorm. That’s my opinion.
